Step-by-step explanation

When the curve y = 8√x on [9, 20] is revolved around the x-axis, the area of the surface generated is 120π.

The surface area of revolution can be obtained by integrating 2π(y) √(1+ (dy/dx)²) dx over the given interval. In this case, y = 8√x, and (dy/dx) = 4/√x.

∴ The surface area is given by:

S = ∫209 (2πy √(1+ (dy/dx)²) dx)

= 2π ∫209 y √(1+ (dy/dx)²) dx

= 2π ∫209 8√x √(1+ (4/√x)²) dx

= 16π ∫209 x √(16 + x) dx

= 16π ∫(209)18 (u-16)² du (where u = x + 16)

After simplification,

S = 16π × 2/3 (u-16)×(3/2) |_9×20

= 32π (16×(3/2) - 8×(3/2))

= 120π (approximately)

Hence, the surface area generated is 120π.

There are 120 different possible combinations for writing the numbers on the six faces of the dice, satisfying the given condition.

To find the different possible combinations for writing the numbers on the six faces of the dice, we can consider the prime factorization of each number from 6 to 11.

The numbers from 6 to 11 are:

6, 7, 8, 9, 10, 11

Prime factorization of these numbers:

6 = 2 * 3

7 = 7

8 = 2^3

9 = 3^2

10 = 2 * 5

11 = 11

Since the highest common factor (HCF) of numbers written on any pair of opposite faces is always 1, it means that no prime factor is common between the numbers on any pair of opposite faces.

To determine the different combinations, we can count the number of ways we can arrange the prime factors on the six faces of the dice without repeating any factor.

The prime factors are:

2, 3, 5, 7, 11

Considering that each face of the dice can have one prime factor, the number of different combinations is equal to the number of ways we can arrange these prime factors.

Using the concept of permutations, the number of different combinations can be calculated as:

5! (5 factorial) which is equal to 5 * 4 * 3 * 2 * 1 = 120

Therefore, there are 120 different possible combinations for writing the numbers on the six faces of the dice, satisfying the given condition.

Answer:

The answer is C) 15

Step-by-step explanation:

a)  The random variable is the number of fish caught in a single cast of the line and and the parameter is the probability of hooking a fish with a single hook

b) The probability of catching 9 fish on a single cast of the line is:

P(X=9) = p^9

c) The probability of catching at least one fish on a single cast is

1 - (1-p)^9

d) The smallest value of n that satisfies this condition is:

n = ⌈log(1-p/100) / log(1-p)⌉

(a) The random variable is the number of fish caught in a single cast of the line, denoted by X. This is a discrete random variable, taking values from 0 to 9. The parameter is the probability of hooking a fish with a single hook, denoted by p.

(b) The probability of catching 9 fish on a single cast of the line is:

P(X=9) = p^9

This is because each hook has a probability of p of catching a fish, and since the events are independent, the probability of all 9 hooks catching a fish is simply the product of their individual probabilities.

(c) The probability of catching at least one fish on a single cast is:

P(X ≥ 1) = 1 - P(X=0)

= 1 - (1-p)^9

This is because the probability of not catching any fish is the complement of the probability of catching at least one fish.

(d) Let n be the number of hooks needed to catch at least one fish on each cast with probability p%. We need to find the smallest value of n that satisfies this condition. Using the complement rule, the probability of not catching a fish with n hooks is:

P(X = 0) = (1-p)^n

So the probability of catching at least one fish is:

P(X ≥ 1) = 1 - (1-p)^n

We want this probability to be at least p%, so we have:

1 - (1-p)^n ≥ p/100

Simplifying, we get:

(1-p)^n ≤ 1 - p/100

Taking the logarithm of both sides, we get:

n log(1-p) ≤ log(1-p/100)

Dividing by log(1-p), we get:

n ≥ log(1-p/100) / log(1-p)

So the smallest value of n that satisfies this condition is:

n = ⌈log(1-p/100) / log(1-p)⌉, where ⌈x⌉ denotes the smallest integer greater than or equal to x.

Answer:

Step-by-step explanation:

Here is the answer

The correlation coefficient measures the strength of the linear relationship between two variables, and it ranges from -1 to 1. A correlation coefficient of -1 indicates a perfect negative linear relationship between the variables, which means that as one variable increases, the other decreases at a constant rate.

To find the value of A in this scenario, we need to look for a perfect negative linear relationship between the two variables, time (x) and distance from destination (y). The table shows that as time increases, the distance from the destination decreases, but we need to find the exact rate of change.

We can calculate the rate of change by finding the slope of the line that represents the relationship between time and distance. We can use the formula for the slope of a line, which is:

slope = (change in y) / (change in x)

If we choose the first and last points in the table, we get:

slope = (690 - 1060) / (7 - 1) = -70

This means that for every hour of time that passes, the distance from the destination decreases by 70 miles. Therefore, if the correlation coefficient is -1, we should see a perfect negative linear relationship between time and distance, with a slope of -70.

To check if A is the correct value, we can use the formula for the equation of a line in slope-intercept form:

y = mx + b

where m is the slope and b is the y-intercept. We can plug in the values of m and b and solve for A:

y = -70x + b

If we use the first point in the table, where x = 4 and y = 1000, we get:

1000 = -70(4) + b

b = 1220

So the equation of the line is:

y = -70x + 1220

If we plug in the values of x for the remaining points in the table, we get:

y = 1030 when x = 0

y = 880 when x = 2

y = 800 when x = 3

y = A when x = 5

y = 760 when x = 6

To find the value of A, we can plug in the corresponding value of y and solve for A:

1030 = -70(0) + 1220

880 = -70(2) + 1220

800 = -70(3) + 1220

760 = -70(6) + 1220

A = -70(5) + 1220 = 850

Therefore, the value of A should be 850 if the correlation coefficient for the data shown in the table is -1.

The profit/loss when 40 watches have their battery changed is $173.60. If the value is positive, it indicates a profit, and if it is negative, it represents a loss. In this case, the watchmaker has a profit of $173.60 when 40 watches have their battery changed.

To calculate the break-even quantity and the profit/loss when 40 watches have their battery changed, we need to consider the fixed costs, variable costs, and the revenue generated from each watch battery replacement. Here are the calculations:

a) Break-even quantity:

The break-even quantity is the number of watch battery replacements at which the revenue equals the total costs (fixed costs plus variable costs). To calculate the break-even quantity, we can use the following formula:

Break-even quantity = Fixed costs / (Revenue per unit - Variable costs per unit)

Given:

Fixed costs = $346

Revenue per unit = $19.99

Variable costs per unit = $7

Break-even quantity = $346 / ($19.99 - $7)

Using a calculator, the calculation would be as follows:

Break-even quantity = $346 / $12.99

Break-even quantity ≈ 26.71

The break-even quantity is approximately 26.71. This means that the watchmaker needs to replace around 27 watch batteries to cover the fixed and variable costs.

b) Profit/loss for 40 watch battery replacements:

To calculate the profit or loss when 40 watches have their battery changed, we need to consider the revenue and total costs.

Revenue = Number of watches * Revenue per unit = 40 * $19.99

Variable costs = Number of watches * Variable costs per unit = 40 * $7

Fixed costs remain the same at $346.

Profit/Loss = Revenue - Total costs

Total costs = Fixed costs + Variable costs

Using a calculator, the calculation would be as follows:

Revenue = 40 * $19.99 = $799.60

Variable costs = 40 * $7 = $280

Fixed costs = $346

Total costs = $346 + $280 = $626

Profit/Loss = $799.60 - $626 = $173.60

The profit/loss when 40 watches have their battery changed is $173.60. If the value is positive, it indicates a profit, and if it is negative, it represents a loss. In this case, the watchmaker has a profit of $173.60 when 40 watches have their battery changed.

The mean number of miles the hiker walked for the 6 days was 6.5 miles.

To calculate the mean or average of a set of numbers, we add up all the numbers and then divide the sum by the number of items in the set. In this case, we have the number of miles the hiker walked on each of the six days. To find the total number of miles the hiker walked, we simply add up all the numbers

8 + 5 + 7 + 2 + 9 + 8 = 39

Next, we divide the total number of miles by the number of days (which is 6) to get the average or mean number of miles the hiker walked per day:

Mean number of miles = Total number of miles / Number of days

= 39 / 6

Therefore, the sum of the measure of angle ABD and measure of angle CBD is equal to 180 degrees, so the angle ABD and angle CBD are supplementary angles

Angle ABD + Angle CBD = 180 degree

The standard deviation of the inside diameter measurements of the old water tank is approximately 0.165m, and the standard deviation of the height measurements is approximately 2.122m.

To calculate the standard deviation, we first find the mean of the inside diameter and height measurements. For the inside diameter, the mean is (4.4 + 4.2 + 4.5 + 4.2) / 4 = 4.325m. we calculate the squared difference between each measurement and the mean, sum them up, and divide by the number of measurements. The result is the variance. Taking the square root of the variance gives us the standard deviation.

For the inside diameter:

Variance = [(4.4 - 4.325)² + (4.2 - 4.325)² + (4.5 - 4.325)² + (4.2 - 4.325)²] / 4 ≈ 0.027m²

Standard Deviation = √0.027m² ≈ 0.165m

For the height:

Mean = (8.8 + 3.9 + 8.6) / 3 ≈ 7.767m

Variance = [(8.8 - 7.767)² + (3.9 - 7.767)² + (8.6 - 7.767)²] / 3 ≈ 4.507m²

Standard Deviation = √4.507m² ≈ 2.122m

These standard deviations indicate the spread or variability of the measurements from the mean. A smaller standard deviation implies that the measurements are closer to the mean, while a larger standard deviation suggests greater variability among the measurements.

Linear functions are functions where the relationship between the independent variable (x) and the dependent variable (y) is a straight line. This means that the graph of a linear function is a straight line and the slope (or rate of change) of the line is constant.

On the other hand, nonlinear functions are functions where the relationship between the independent variable (x) and the dependent variable (y) is not a straight line. The graph of a nonlinear function is often a curve, and the slope (or rate of change) of the curve can vary.

b) The percentage of ball bearings will be discarded is 0.26%

c) We would expect to find approximately 78 faulty ball bearings in a batch of 30,000.

d)  We need to produce 30,008 ball bearings to fulfill the order for exactly 30,000 ball bearings.

e) If a small batch of 100 ball bearings are randomly and independently selected for quality control, then the probability that only 5 out of 100 ball bearings will be faulty is approximately 0.2195 or 21.95%.

a) To calculate the probability of randomly selecting a ball bearing with a diameter exceeding 5.03mm, we can use the normal distribution function with a mean of 5mm and a standard deviation of 0.02mm. The formula for the normal distribution function is:

f(x) = (1/σ√(2π)) * \(e^{-(x-\mu)^2\)/(2σ²))

Where μ is the mean, σ is the standard deviation, x is the value we want to find the probability for, e is the mathematical constant approximately equal to 2.71828, and π is the mathematical constant approximately equal to 3.14159.

We want to find the probability that x is greater than 5.03, so we need to find the area under the normal distribution curve to the right of 5.03. We can use a standard normal distribution table or calculator to find that the probability is approximately 0.0478 or 4.78%.

b) To determine the percentage of ball bearings that will be discarded due to their diameter being outside the range of 4.95mm to 5.05mm, we need to find the area under the normal distribution curve that falls outside of this range.

P(x < 4.95 or x > 5.05) = P(x < 4.95) + P(x > 5.05)

= (1/0.02√(2π)) * \(e^{(-((4.95-5)^2)}\)/(20.02²)) + (1/0.02√(2π)) * \(e^{(-((4.95-5)^2)}\)/(20.02²))

= 0.0013 + 0.0013

= 0.0026

Percentage of ball bearings that will be discarded = 0.0026 * 100%

= 0.26%

c) To find the expected number of faulty ball bearings in a batch of 30,000, we can use the mean and standard deviation of the normal distribution to calculate the expected value of the number of ball bearings that fall outside of the range of 4.95mm to 5.05mm.

We can calculate the expected value of the number of faulty ball bearings as follows:

E(X) = μ * n

= (P(x < 4.95 or x > 5.05)) * n

= 0.0026 * 30,000

= 78

d) To fulfill an order for exactly 30,000 ball bearings, we need to produce more than 30,000 ball bearings to account for the percentage of ball bearings that will be discarded. We can use the percentage of ball bearings that will be discarded (0.26%) from part (b) to calculate the total number of ball bearings that need to be produced. The formula is:

Total number of ball bearings needed = 30,000 / (1 - percentage of ball bearings that will be discarded)

= 30,000 / (1 - 0.0026)

= 30,007.8 (rounded up to the nearest whole number)

e) To find the probability that only 5 out of 100 ball bearings will be faulty, we can use the binomial distribution function.

In this case, n = 100, x = 5, and p is the probability that a ball bearing is faulty, which we can calculate using the probability from part (b) (0.0026).

f(5) = (¹⁰⁰C₅) * 0.0026⁵ * (1-0.0026)¹⁰⁰⁻⁵

= (100! / (5! * 95!)) * 0.0026^5 * 0.9974^95
