Calculate the slope of the line for Graph C.

Probability of having between 15 and 33 days of vacation = 0.933 - 0.067 = 0.866

First, we need to standardize the values of 15 and 33 days of vacation by subtracting the mean (24) and dividing by the standard deviation (6).

15 days of vacation: (15 - 24) / 6 = -1.5

33 days of vacation: (33 - 24) / 6 = 1.5

Next, we can use the standard normal distribution to find the probabilities of having less than 15 and 33 days of vacation.

The probability of an individual having less than 15 days of vacation is 0.067.

The probability of an individual having less than 33 days of vacation is 0.933.

Finally, we can subtract the probability of having less than 15 days of vacation from the probability of having less than 33 days of vacation. This gives us the probability of having between 15 and 33 days of vacation.

Probability of having between 15 and 33 days of vacation = 0.933 - 0.067 = 0.866

Answer: it weighs about 80 ounces

Step-by-step explanation:

a-1. The expected value and standard error of the given sample proportion is 0.167 and 0.0287.

a-2.  It is appropriate to use the normal distribution approximation for the sample proportion because np ≥ 5 and n(1 - p) ≥ 5. Therefore, the correct option is 1.

b. The probability that more than 20% of smartphone users in the sample have fallen prey to cyber-attack is 0.125.

1. Determine the population proportion (p): p = 1/6

2. Calculate the sample size (n): n = 200

3. Find the expected value (E): E = p = 1/6 ≈ 0.167 (rounded to 2 decimal places)

4. Calculate the standard error (SE): SE = sqrt(p * (1 - p) / n) = sqrt(0.167 * (1 - 0.167) / 200) ≈ 0.0287 (rounded to 4 decimal places)

Hence,

Expected value: 0.167

Standard error: 0.0287

1. np ≥ 5: 200 * 0.167 = 33.4 ≥ 5

2. n(1 - p) ≥ 5: 200 * (1 - 0.167) = 166.6 ≥ 5

Since both conditions are met, it is appropriate to use the normal distribution approximation.

Yes, because np ≥ 5 and n(1 - p) ≥ 5. Hence, option 1 is correct.

1. Calculate the z-score: z = (sample proportion - population proportion) / standard error = (0.2 - 0.167) / 0.0287 ≈ 1.150

2. Use a standard normal distribution table or calculator to find the probability corresponding to the z-score: P(z > 1.150) ≈ 0.125

The probability that more than 20% of smartphone users in the sample have fallen prey to cyber-attack is 0.125.

Step-by-step explanation:

hope it helps ^^

Answer:

y = -x - 2

Step-by-step explanation:

Since we have a straight, linear line, the line follows the y = mx + b format

The line moves one unit down for every unit to the right, making m = 1

Since the line has a downward slope, m = -1

Since the line crosses the y-axis at -2, b = -2

Therefore, the equation is y = -1x - 2 or more simplified, y = -x - 2

Answer:

Average rate of fall = \(\frac{h(3)-h(0)}{3}\)

Step-by-step explanation:

Since they give you an expression for the position of the object as a function of time, one can derive the average velocity of the object during the first 3 seconds of the fall by estimating the position of the object at time 0, the position of the object at time 3 seconds, finding the displacement of the object (distance covered) in that interval of time (via a subtraction of these two quantities), and finally dividing this change by the elapsed time (3 seconds) thus using the concept that velocity is the quotient between distance covered over the elapsed time:

Average rate of fall = (h(3) - h(0))/ 3

Average rate of fall = \(\frac{h(3)-h(0)}{3}\)

f(g(x)) or (f ∘ g)(x) represents the composition of functions f(x) & g(x), where g(x) acts first (x). It integrates a number of functions to produce another.

The output of one function inside the parenthesis is becoming the input of the other function in a function composition. i.e.,

Now, as per the given question;

To create a composite function, we pertain one function to another. In this scenario, we would like to find area in terms of time, so we apply the function A(r) to the function r. (t).

To accomplish this, we substitute r with r(t).

Since we know that r(t) = 0.5 + 2t, we can replace r to 0.5 + 2t:

A(r(t)) = π(0.5+2t)²

To make things easier, we'll simplify this same squared term:

A(r(t)) = π(0.5 + 2t)(0.5 + 2t)

A(r(t)) = π[(0.5×0.5) + (0.5×2t) + (2t×0.5) + (2t×2t)]

A(r(t)) = π(0.25 + t + t + 4t²)

A(r(t)) = π(0.25 + 2t + 4t²)

The speed of the star as compared to the speed of the star relative to earth is the frequency of light emitted by the source.

A star moving away from the observer (say on Earth) will have its emitted light red-shifted (move to lower frequency), i.e., the spectrum moving to left if we consider the intensity of light is plotted as a function of frequency with the frequency increasing from left to right.

A star moving towards the observer (say on Earth) will have its emitted light blue-shifted (move to higher frequency), i.e., the spectrum moving to the right if we consider the intensity of light is plotted as a function of frequency with the frequency increasing from left to right.

A star moving perpendicular to the observer (say on Earth) will have its emitted light will no change with respect to the spectrum of the stationary star.

These are due to the Doppler effect, the equation of frequency detected by the observer as

\(f_{0} = f_{s}\sqrt{\frac{1-\beta }{1+\beta } }\) where \(\beta = \frac{v}{c}\), v the relative velocity of the moving source (the star here), f^s is the frequency of light emitted by the source.

Step-by-step explanation:

Since S satisfies both defining properties of an ideal in R, we can conclude that S is indeed an ideal in R.

To prove that the subset S = {λ1r1 +···+ λnrn | λ1,...,λn ∈ R} is an ideal in R, we need to show that it satisfies the two defining properties of an ideal:

1. S is a subgroup of R under addition.
2. S is closed under multiplication by elements of R.

First, let's show that S is a subgroup of R under addition.

- Closure under addition: Let x,y ∈ S, so that x = λ1r1 + ··· + λnrn and y = μ1r1 + ··· + μnrn for some λi,μi ∈ R. Then their sum is x + y = (λ1 + μ1)r1 + ··· + (λn + μn)rn, which is in S since each coefficient is still in R.

- Additive inverse: Let x ∈ S, so that x = λ1r1 + ··· + λnrn for some λi ∈ R. Then its additive inverse is -x = (-λ1)r1 + ··· + (-λn)rn, which is also in S since each coefficient is still in R.

Therefore, S is a subgroup of R under addition.

Next, let's show that S is closed under multiplication by elements of R.

- Closure under left multiplication: Let r ∈ R and x ∈ S, so that x = λ1r1 + ··· + λnrn for some λi ∈ R. Then their product is rx = (rλ1)r1 + ··· + (rλn)rn, which is in S since each coefficient is still in R.

- Closure under right multiplication: This follows from the distributive property of multiplication over addition.

Therefore, S is closed under multiplication by elements of R.

Since S satisfies both defining properties of an ideal in R, we can conclude that S is indeed an ideal in R.

NUMBER ONE

The slope of tghe line (m) = (y₂ - y₁) ÷ (x₂ - x₁)

                                           =  (- 9 - (-9)) ÷ ( 5 - (-3))

                                           =    0

The slope is zero because the y values of the line remain the same which means the line doesn't slope or rise.

We can now use the point-slope form to write the equation for this line:

y - y₁ = m(x - x₁)

            y - (-9) = 0 (x - (-3))

             y + 9  = 0

                   y  =  - 9

NUMBER TWO

For the slope-intercept form ( y = mx + c ) we need two main things: the slope (m) and the y-intercept (c)

slope = (y₂ - y₁) ÷ (x₂ - x₁)  = (10 - (-11)) ÷ (-2 - 5)

                                        =  21 ÷ (-7)

                                         = - 3

Let's write the equation without the value of c. This will help us solve for it.

                  y = -3x + c

if we substitute in a point give (-2 , 10) we can find c

                  10 = -3 (-2) + c

                   10 = 6 + c

                    c = 10 -6

                    c = 4

⇒ the equation of the line is y = -3x + 4

Jon will pay $3476.88 for the vacation package after the 25% discount and 9% resort charge are applied.

If the vacation package is obtainable for 25% off, then Jon will pay 75% of the original price. To discover the price after the discount, we can now multiply the original fee via 0.75:

Discounted charge = 0.75 x $4250 = $3187.50

Next, we need to add the 9% resort charge to the discounted fee. To do that, we are able to do multiply the discounted price by using 1.09:

There are 64 teams in the sample space. There are 16 teams in the event W. p(W) = 0.25, is the probability that a randomly chosen team is in event W.

Since the teams are divided equally into four regions, there are 16 teams in the event W (assigned to the West region). The probability that a randomly chosen team is in event W, p(W), is the number of teams in event W divided by the total number of teams in the sample space. So, p(W) = 16/64 = 1/4 or 0.25. There are 64 teams in the sample space. There are 16 teams in the event W (since each region has 16 teams). P(W) = 16/64 = 0.25, which is the probability that a randomly chosen team is assigned to the West region.

The minimum cost of the food that satisfies the requirements is $2.60, and this occurs when the zoo uses 2 units of Custom Foods and 4 units of Zookeeper’s Best.

Let x be the number of units of Custom Foods and y be the number of units of Zookeeper’s Best required. Then, the cost can be expressed as:

C = 0.8x + 0.5y

Since each serving must have at least 60 grams of protein and 30 grams of fat, we have the following inequalities:

15x + 20y ≥ 60 (for protein)

10x + 5y ≥ 30 (for fat)

Simplifying the inequalities, we get:

3x + 4y ≥ 121x + y ≥ 6

We can solve this system of inequalities by graphing the equations on a coordinate plane:

Since the feasible region lies above and to the right of the line 3x + 4y = 12 and above and to the right of the line x + y = 6, the corner points are as follows:(0, 6), (2, 4), (4, 3), and (6, 0)

For each corner point, we can calculate the cost:

C(0, 6) = 0.8(0) + 0.5(6) = 3

C(2, 4) = 0.8(2) + 0.5(4) = 2.6

C(4, 3) = 0.8(4) + 0.5(3) = 4.2

C(6, 0) = 0.8(6) + 0.5(0) = 4.8

Therefore, the minimum cost of the food that satisfies the requirements is $2.60, and this occurs when the zoo uses 2 units of Custom Foods and 4 units of Zookeeper’s Best.

the answer is (D) XY = 11 mm, YZ = 12 mm, XZ = 28 mm would NOT form a triangle with vertices X, Y, and Z.

How to solve the question?

To determine whether a triangle can be formed using the given side lengths, we need to apply the Triangle Inequality Theorem, which states that the sum of any two sides of a triangle must be greater than the third side.

Let's check each option:

A. XY = 11 mm, YZ = 12 mm, XZ = 18 mm

To form a triangle, we need to check whether the sum of any two sides is greater than the third side. Let's check:

XY + YZ = 11 mm + 12 mm = 23 mm > XZ = 18 mm

YZ + XZ = 12 mm + 18 mm = 30 mm > XY = 11 mm

XY + XZ = 11 mm + 18 mm = 29 mm > YZ = 12 mm

All the combinations are greater than the third side, so a triangle can be formed with these side lengths.

B. XY = 16 mm, YZ = 12 mm, XZ = 23 mm

Let's check whether the sum of any two sides is greater than the third side:

XY + YZ = 16 mm + 12 mm = 28 mm > XZ = 23 mm

YZ + XZ = 12 mm + 23 mm = 35 mm > XY = 16 mm

XY + XZ = 16 mm + 23 mm = 39 mm > YZ = 12 mm

Again, all the combinations are greater than the third side, so a triangle can be formed with these side lengths.

C. XY = 16 mm, YZ = 17 mm, XZ = 18 mm

Let's check whether the sum of any two sides is greater than the third side:

XY + YZ = 16 mm + 17 mm = 33 mm > XZ = 18 mm

YZ + XZ = 17 mm + 18 mm = 35 mm > XY = 16 mm

XY + XZ = 16 mm + 18 mm = 34 mm > YZ = 17 mm

All the combinations are greater than the third side, so a triangle can be formed with these side lengths.

D. XY = 11 mm, YZ = 12 mm, XZ = 28 mm

Let's check whether the sum of any two sides is greater than the third side:

XY + YZ = 11 mm + 12 mm = 23 mm < XZ = 28 mm

YZ + XZ = 12 mm + 28 mm = 40 mm > XY = 11 mm

XY + XZ = 11 mm + 28 mm = 39 mm > YZ = 12 mm

The first combination is less than the third side, so a triangle cannot be formed with these side lengths.

Therefore, the answer is (D) XY = 11 mm, YZ = 12 mm, XZ = 28 mm would NOT form a triangle with vertices X, Y, and Z.

The model consists of four stages: forming, storming, norming, and performing.

The forming stage is characterized by a sense of excitement and anticipation as group members first come together. During this stage, members focus on getting to know one another, establishing goals and objectives, and understanding the task at hand.

The storming stage is characterized by conflict and disagreement as group members begin to assert themselves and their ideas. During this stage, there may be tension as different personalities and approaches clash, and members may question the group's direction or leadership.

The probability of guessing the correct answer for each question is 1/4, while the probability of guessing incorrectly is 3/4.

To calculate the probability of answering at most one correct answer, we need to consider two cases: answering zero correct answers and answering one correct answer.

For the case of answering zero correct answers, the probability can be calculated as (3/4)^5, as there are five independent attempts to answer incorrectly.

For the case of answering one correct answer, we have to consider the probability of guessing the correct answer on one question and incorrectly guessing the rest. Since there are five questions, the probability for this case is 5 * (1/4) * (3/4)^4.

To obtain the probability of answering at most one correct answer, we sum up the probabilities of the two cases:

Probability = (3/4)^5 + 5 * (1/4) * (3/4)^4.

Therefore, by calculating this expression, you can determine the probability of answering at most one correct answer among five questions when guessing randomly.
