Answers

Mean length of steel rods is 23 cm and the standard deviation is 0.08.

Find out what proportion of rods has a length less than 22.9 cm.

z-score as shown below:z = (x - μ) / σ, where x is the given value, μ is the mean, and σ is the standard deviation.z = (22.9 - 23) / 0.08 = -1.25

Proportion = P(Z < -1.25) = 0.1056Therefore, the proportion of rods that have a length less than 22.9 cm is 0.1056.

Now, we have to find the proportion of rods that will be discarded

z-score for 22.82 cm is given by z = (22.82 - 23) / 0.08 = -2.25And, z-score for 23.18 cm is given by z = (23.18 - 23) / 0.08 = 2.25

To find the proportion of rods that have a length shorter than 22.82 cm.Proportion for Z < -2.25 is 0.0122And, the proportion of rods that have a length longer than 23.18 cm is P(Z > 2.25) = 0.0122

Thus, the proportion of rods that will be discarded is 0.0122 + 0.0122 = 0.0244.c)

We have found that the proportion of rods that will be discarded is 0.0244. The number of rods to be discarded in a day is given by:Discarded rods = 0.0244 × 5000= 122

Therefore, the plant manager should expect to discard 122 rods in a day.

We have been given that all rods must be between 22.9 cm and 23.1 cm and we have to find how many rods should the plant manager expect to manufacture if an order comes in for 10,000 steel rods.

To solve this, we need to find the proportion of rods that have a length between 22.9 cm and 23.1 cm.z-score for 22.9 cm is given by z = (22.9 - 23) / 0.08 = -1.25And, z-score for 23.1 cm is given by z = (23.1 - 23) / 0.08 = 1.25

Proportion = P(-1.25 < Z < 1.25) = 0.7887Therefore, the proportion of rods that will be manufactured with a length between 22.9 cm and 23.1 cm is 0.7887.So, the plant manager should expect to manufacture 0.7887 × 10,000 = 7887 rods.

Rounding up to the nearest integer gives us 7887 as the answer.

a tank contains 1120 l of pure water. solution that contains 0.08 kg of sugar per liter enters the tank at the rate 4 l/min, and is thoroughly mixed into it. the new solution drains out of the tank at the same rate. (a) how much sugar is in the tank at the begining?

Answers

a) 0 kg of sugar is in the tank at the beginning., b) ds/dt = 0.08-(S/1120)*4, c) 0.32 kg of sugar is in the tank after 1 minute., d) 2.59 kg of sugar is in the tank after 84 minutes.

a) At the beginning, there is no sugar in the tank since it contains only pure water.

b) Let S(t) be the amount of sugar in the tank at time t (in minutes). The rate of change of S is given by the rate at which sugar enters the tank minus the rate at which it leaves. Since the solution enters at a rate of 4 L/min, and contains 0.08 kg of sugar per liter, the rate at which sugar enters is 0.08 kg/L * 4 L/min = 0.32 kg/min. Since the solution leaves at the same rate, the differential equation that models the situation is:

dS/dt = 0.32 - (S/1120) * 4

c) To find the amount of sugar after 1 minute, we need to solve the differential equation from part (b) with the initial condition S(0) = 0 (since the tank initially contains only water). One possible way to solve the differential equation is to use separation of variables:

dS/dt + (4/1120) S = 0.32

Multiplying both sides by dt and dividing by (0.32 - (4/1120) S), we get:

(1/S) dS = (4/0.32 - (1120/4)) dt

Integrating both sides from t = 0 to t = 1 and from S = 0 to S = S(1), we get:

ln(S(1)) - ln(0) = (1.25 - 280) * 1

S(1) = \(e^{0.25} * 1120\) ≈ 300.92 kg

Therefore, after 1 minute, there is approximately 300.92 kg of sugar in the tank.

d) To find the amount of sugar after 84 minutes, we can solve the differential equation from part (b) numerically using an appropriate method such as Euler's method, or we can use an integrating factor to solve it analytically. One possible way to use an integrating factor is to multiply both sides of the differential equation by exp(4t/1120):

exp(4t/1120) dS/dt + (S/280) exp(4t/1120) = 0.32 exp(4t/1120)

This can be written as:

d/dt [S exp(4t/1120)] = 0.32 exp(4t/1120)

Integrating both sides from t = 0 to t = 84, we get:

[S(84) exp(4/1120 * 84)] - [S(0) exp(4/1120 * 0)] = ∫(0 to 84) 0.32 exp(4t/1120) dt

Since S(0) = 0 and exp(4/1120 * 84) is a constant, we can simplify this to:

S(84) = (1/exp(4/1120 * 84)) ∫(0 to 84) 0.32 exp(4t/1120) dt

Using integration by substitution with u = 4t/1120, we get:

S(84) = (1/exp(4/1120 * 84)) * (1120/4) * (0.32/4) * [exp(4/1120 * 84) - 1]

S(84) ≈ 301.53 kg

Therefore, after 84 minutes, there is approximately 301.53 kg of sugar in the tank.

Q1. Find the gradient of function x^3e^xy+e^2x at (1,2).
Q2. Find the divergence of F = xe^xy i+y^2 z j+ze^2xyz k at (−1,2,−2). Q3. Find the curl of F = y^3z^3 i+2xyz^3 j+3xy^2z^2k at (−2,1,0).

Answers

The solutions are:

1) Gradient ∇f(1, 2) = (5e², e²)

2) Divergence of F at (-1, 2, -2) is 3e⁻² - 60e⁸ - 4.

3) Curl is the zero vector (0, 0, 0).

Given data:

To find the gradient, divergence, and curl of the given functions, we need to use vector calculus.

1)

The gradient of a function is represented by the symbol ∇.

The gradient of a scalar function \(f(x, y) = x^3e^{xy} + e^2x\)  can be found by taking the partial derivatives with respect to x and y:

∂f/∂x = 3x²e^xy + 2e²ˣ

∂f/∂y = x⁴e^xy

Now, substituting the given point (1, 2) into the partial derivatives:

∂f/∂x = 3e² + 2e² = 5e²

∂f/∂y = (1)⁴e¹ˣ² = e²

Therefore, the gradient at (1, 2) is given by:

∇f(1, 2) = (5e², e²)

2)

The divergence of a vector field F = Fx i + Fy j + Fz k is given by

∇·F = ∂Fx/∂x + ∂Fy/∂y + ∂Fz/∂z

To find the divergence, we need to compute the partial derivatives of each component and evaluate them at the given point (-1, 2, -2):

∂Fx/∂x = e^xy + ye^xy

∂Fy/∂y = 2z

∂Fz/∂z = e^2xyz + 2xyze^2xyz

Substituting the values x = -1, y = 2, and z = -2 into each partial derivative:

∂Fx/∂x = 3e⁻²

∂Fy/∂y = 2(-2) = -4

∂Fz/∂z = 4e⁸ - 64e⁸ = -60e⁸

Finally, calculating the divergence at (-1, 2, -2):

∇·F = ∂Fx/∂x + ∂Fy/∂y + ∂Fz/∂z =  3e⁻² - 60e⁸ - 4

Therefore, the divergence of F at (-1, 2, -2) is 3e⁻² - 60e⁸ - 4

3)

The curl of a vector field F = Fx i + Fy j + Fz k is given by the following formula:

∇ × F = (∂Fz/∂y - ∂Fy/∂z) i + (∂Fx/∂z - ∂Fz/∂x) j + (∂Fy/∂x - ∂Fx/∂y) k

To find the curl, we need to compute the partial derivatives of each component and evaluate them at the given point (-2, 1, 0):

∂Fx/∂y = 3y²z³

∂Fy/∂x = 2yz³

∂Fy/∂z = 6xyz²

∂Fz/∂y = 0

∂Fz/∂x = 0

∂Fx/∂z = 0

Substituting the values x = -2, y = 1, and z = 0 into each partial derivative:

∂Fx/∂y = 0

∂Fy/∂x = 0

∂Fy/∂z = 0

∂Fz/∂y = 0

∂Fz/∂x = 0

∂Fx/∂z = 0

Finally, calculating the curl at (-2, 1, 0):

∇ × F = (0 - 0) i + (0 - 0) j + (0 - 0) k = 0

Therefore, the curl of F at (-2, 1, 0) is the zero vector (0, 0, 0).

A softball player has had 8 base hits out of 25 at bats for a current batting average of 8/25 = .320.

Answers

Using proportions, it is found that she needs 4 consecutive hits to raise her batting average to .400.

What is a proportion?

A proportion is a fraction of a total amount.

Hence, the batting average is given by the number of hits divided by the number of at-bats.

If she gets x consecutive hits, she will have 8 + x hits in 25 + x at-bats, for an average of 0.400, hence:

\(0.4 = \frac{8 + x}{25 + x}\)

8 + x = 10 + 0.4x

Vector subtraction is done by arranging head to tail.

Vector subtraction is the process of finding the vector that results from taking away one vector from another. To perform vector subtraction, we arrange the vectors head to tail, with the tail of one vector touching the head of the other vector. We then draw a new vector from the tail of the first vector to the head of the second vector. The resulting vector is the difference between the two vectors. This can be mathematically represented as:

Answers

Tamara pays $80 upfront and then $25 per month. Tamara pays $45 per month without any upfront membership fee. So the total cost after 'n' months would be 45n. Hence, both plans will be equal after 4 months.

Let's denote the number of months as 'n'. For the first plan, Tamara pays $80 upfront and then $25 per month. So the total cost after 'n' months would be 80 + 25n.

For the second plan, Tamara pays $45 per month without any upfront membership fee. So the total cost after 'n' months would be 45n.

To find the month when both plans are equal, we set up the equation 80 + 25n = 45n and solve for 'n'.

80 + 25n = 45n

A spherical helium-filled balloon with a diameter of 30 centimeters can lift a 14-gram object. Find the size of a balloon that could lift a person who weighs 65 kilograms. Round to the nearest tenth.

Answers

The diameter of the balloon that can lift a person weighing 65Kg is  299.72 cm.

To get the diameter of the balloon that can lift a person weighing 65 Kg, we need to know the volume which this diameter will occupy

Since, density is constant, what will change will be the volume and the weight.

Hence, the ratio of the volume to the weight at any point in time irrespective of the weight and volume will be the same.

With a 30cm diameter, the volume that can be lifted would be the volume of a sphere with diameter 30cm. If the diameter is 30, then the radius is 15.

The volume of a sphere = 4/3 × π× 15³ = 4/3 × π × 15³ = 1125π

So, what this means is that, a spherical helium balloon of size 1125π  can lift a person weighing 14 gram object .

Now, let the radius of the balloon that can lift a person of weight 65 Kg be x feet

The needed volume is thus 4/3 × π× x³ = 4π * x³/3

Now let's make a relationship;

A volume of  1125π   lifts 14 gram

A volume of  4π *x³/3     lifts 65 Kg pounds

To get x, we simply use a cross-multiplication;

1125π  × 65 = 4π * x³/3  × 0.014

x = 149.86 cm

Since the radius is  149.86cm, the diameter will be 2 × 149.86 =  299.72 cm.

Answers

The average yearly growth rate of the height of the tree is approximately -5.55 feet/year.

To calculate the average yearly growth rate of the tree, we need to find the total change in height over the given time period and divide it by the number of years.

The initial height of the tree is 4012 feet, and the final height is 57 feet. The total change in height is:

Total change in height = Final height - Initial height

= 57 feet - 4012 feet

= -3955 feet

The negative sign indicates a decrease in height.

The time period is 712 years.

Average yearly growth rate = Total change in height / Number of years

= -3955 feet / 712 years

≈ -5.55 feet/year

The average yearly growth rate of the height of the tree is approximately -5.55 feet/year. Note that the negative sign indicates a decrease in height over time.

The ratio test can be applied to series with non-negative terms.  From the given series, The nth term of a series is given by  an=2^n/5^n+1 ⋅n  By applying the ratio test, we get; an+1/an = [2^(n+1)/(5^(n+1) + 1)*(n + 1)] / [2^n / (5^n + 1)*n] an+1/an = [2^(n+1)*n / (5^(n+1) + 1)*n+1] * [(5^n + 1)*n / 2^n] an+1/an = (2n / (5n + 1)) * (5n + 1) / 2an+1/an = n / 5n + 1 Therefore, we have r = lim n→∞ | an+1/an |= lim n→∞ |n/5n+1| = 1/5 < 1 From the ratio test, r = 1/5. Since r < 1, the series converges.

Therefore, the correct statement reflecting George's conclusion is "From the ratio test, r = 0.4. The series converges."

108° 4x+8° O alternate interior corresponding vertical linear pair same-side Interior alternate exterior degrees

108 4x+8 O alternate interior corresponding vertical linear pair same-side Interior alternate exterior

Answers

Answer:

Alternate Interior angles

x = 25

Explanations:

By careful observation of the diagram, we would see that both angles are at the opposite sides of the transversal. At the same time, they are at the interior of the two parallel lines.

This means that <108 and <4x + 8 are alternate interior angles.

Since the two lines intersecting the transversal are parallel, the alternate interior angles are equal

That is,

4x + 8 = 108

4x = 108 - 8

4x = 100

x = 100/4

x = 25

The Benefits of Using the 4-Step Method to Solve Problems

Problem solving is an essential skill in life. It helps us to find solutions to difficult situations and can be applied to almost any area of life. One effective way to approach problem solving is to use the 4-step method. This method is designed to help you analyze a situation, plan an action, execute the plan, and evaluate the results. In this essay, we will discuss the benefits of using the 4-step method to solve problems.

The first step of the 4-step method is to analyze the situation. This involves identifying the problem and its causes. Taking the time to understand the problem before attempting to solve it can help ensure that the solution is effective. By analyzing the situation, you can determine the most effective solution and avoid wasting time and resources on ineffective solutions.

The second step of the 4-step method is to plan an action. This involves developing a plan of action to address the problem. Taking the time to plan ahead can help ensure that the solution is tailored to the specific situation. It can also help to minimize the risk of unexpected problems or delays during the execution of the plan.

jada biked 3/5 kilometer and then stopped to adjust her helmet. she biked another 12 kilometer and stopped to drink some water. jada has to bike a total of 3 kilometers.how many more kilometers does jada have to bike?responses

Answers

The remaining distance Jada has to bike is 19/10 km.

Distance is a measurement of how far apart two things or points are, either numerically or occasionally qualitatively. The distance can refer to a physical length in physics or to an estimate based on other factors in common usage.

Jada biked for 3.5 kilometers before stopping to adjust the helmet.

d₁ = 3/5 kilometer

Jada bikes another 1/2 kilometer and stopped to drink water.

d₂ = 1/2 kilometer

The total distance Jada has to bike is 3 kilometers.

The distance traveled by Jada is:

= d₁ + d₂

= 3/5 km + 1/2 km

Using LCM,

= ( 6 + 5 ) / 10

= 11/10 km

The distance remaining to cover is :

- 3 km - 11/10 km

= ( 30 - 11 ) / 10 km

= 19/10 km

The drama club is selling tickets to their play to raise money for the show's expenses. Each student ticket sells for $7.50 and each adult ticket sells for $11. The drama club must make no less than $990 from ticket sales to cover the show's costs. Write an inequality that could represent the possible values for the number of student tickets sold, ss, and the number of adult tickets sold, aa, that would satisfy the constraint.

Answers

Answer: ss*$7.50 + aa*$11 ≥ $990.

Step-by-step explanation:

We have two variables:

aa = # of adult tickets sold.

ss = # of student tickets sold.

The total profit is:

P = ss*$7.50 + aa*$11

And we want P ≥ $990.

Then we can write the inequality:

ss*$7.50 + aa*$11 ≥ $990.

Now, we have only one equation and two variables, so there are a lot of possible solutions for this system.

use the method of cylindrical shells to find the volume v of the solid obtained by rotating the region bounded by the given curves about the x-axis. xy = S, x =0, y=5, y=?

Answers

The volume of the solid obtained by rotating the region about the x-axis is 2π * [5S * ln(5) + S^2/5].

To find the volume of the solid obtained by rotating the region bounded by the curves xy = S, x = 0, and y = 5 about the x-axis using the method of cylindrical shells, we'll integrate the volume of the cylindrical shells.

The region bounded by the curves xy = S, x = 0, and y = 5 can be rewritten as x = S/y.

The height of each cylindrical shell will be the difference between the upper and lower boundaries, which is 5 - (S/y).

The radius of each cylindrical shell will be the x-coordinate, which is x = S/y.

The differential thickness of each cylindrical shell is given by dy.

Therefore, the volume of each cylindrical shell is given by dV = 2π(S/y) * (5 - (S/y)) * dy.

To find the total volume, we integrate this expression over the range of y values that define the region, which is from y = 0 to y = 5.

v = ∫[0,5] 2π(S/y) * (5 - (S/y)) dy

Simplifying the integrand, we get:

v = 2π * ∫[0,5] (5S/y - S^2/y^2) dy

v = 2π * [5S * ln|y| + S^2/y] [0,5]

Evaluating the integral and subtracting the lower limit from the upper limit, we have:

v = 2π * [5S * ln(5) + S^2/5]

Therefore, the volume of the solid obtained by rotating the region about the x-axis is 2π * [5S * ln(5) + S^2/5].

The experimental probability of each event is as follows:

Landing open side up = 1/50 = 0.02 = 2%.Landing closed side up = 5/50 = 1/10 = 0.1 = 10%.Landing on its side = 44/50 = 0.88 = 88%.

The experimental probability of an event is the ratio of the number of outcomes that favored the event to the total number of outcomes in the experiment.

In the question, we are given that Jake tossed a paper cup 50 times and recorded the position how it landed, which is shown in the table:

Open-sided up: 1

Closed side up 5

On the side: 44.

We are asked to determine the experimental probability of each outcome.

The number of outcomes, when the landing is open-sided up is 1.

The number of outcomes, when the landing is closed-sided up is 5.

The number of outcomes, when the landing is on the side up is 44.

The total number of times the experiment took place is 50.

Thus, the experimental probability of each event is as follows:

Landing open side up = 1/50 = 0.02 = 2%.Landing closed side up = 5/50 = 1/10 = 0.1 = 10%.Landing on its side = 44/50 = 0.88 = 88%.
