The company should use a one-sample t-test. A one-sample t-test is appropriate when the research question involves comparing the mean of a single sample to a known or hypothesized population mean.

In this case, the company wants to test if the employees spend more than 6 hours a day on their feet. By collecting a sample of 500 employees and monitoring their hours on their feet, the company can calculate the mean of the sample and compare it to the hypothesized mean of 6 hours.

The one-sample t-test allows the company to determine whether the observed mean of the sample significantly differs from the hypothesized mean. If the calculated t-value is large enough and the p-value is below a predetermined significance level, the company can conclude that the employees' average time spent on their feet is significantly different from 6 hours per day. This type of t-test is commonly used when examining the effects of a single treatment or condition on a sample.

Absolute error and relative error are two measures of the difference between an estimated or calculated value and the true or exact value of a quantity.

The main difference between absolute and relative error is that absolute error gives the magnitude of the difference between the estimated value and the true value, while relative error gives a measure of this difference relative to the size of the true value.

Absolute error is the magnitude of the difference between the estimated or calculated value and the true value.

It is calculated as the absolute value of the difference between the estimated value and the true value. Absolute error is expressed in the same units as the quantity being measured.

Relative error, on the other hand, is the absolute error expressed as a fraction or percentage of the true value. It is calculated as the absolute error divided by the true value, and is usually expressed as a percentage.

Relative error is a useful measure when the scale of the quantity being measured varies over a wide range, or when comparing the accuracy of measurements of different quantities.

John sold 55 hot dogs and 34 cokes.

Assume the number of hot dogs sold is represented by "x" and the number of cokes sold is represented by "y."

According to the given information, each hot dog costs $1.50 and each coke costs $0.75. The total revenue from the hot dogs can be calculated as 1.5x, and the total revenue from the cokes can be calculated as 0.75y.

We know that the total number of hot dogs and cokes sold together is 89, so we can write the equation:

x + y = 89   ---(equation 1)

The total revenue from selling hot dogs and cokes is $108, so we can write the equation:

1.5x + 0.75y = 108   ---(equation 2)

We now have a system of two equations with two variables. We can solve this system to find the values of x and y.

Using equation 1, we can express y in terms of x:

y = 89 - x

Substituting this value of y in equation 2:

1.5x + 0.75(89 - x) = 108

1.5x + 66.75 - 0.75x = 108

0.75x = 108 - 66.75

0.75x = 41.25

x = 41.25 / 0.75

x = 55

So, John sold 55 hot dogs.

Substituting the value of x in equation 1:

55 + y = 89

y = 89 - 55

y = 34

Therefore, John sold 55 hot dogs and 34 cokes.

If the material used for the half-spheres are three times more expensive than the material used for the part cylindrical, then the radius of the cylindrical part should be (125/3π)^(1/3) meters and the length of the cylindrical part should be 11.99 meters.

The radius and length of the cylindrical part that will minimize the cost of building the tank, can be determined by considering the cost of the materials used for the half-spheres and the cylindrical part.

Let's start by finding the volume of the cylindrical part. The volume of a cylinder is given by the formula

V = πr²h, where r is the radius and h is the height or length of the cylindrical part.

In this case, we want the volume to be 1000m³, so we can write the equation as:

1000 = πr²h ...(1)

Next, let's find the surface area of the two half-spheres. The surface area of a sphere is given by the formula:

A = 4πr².

Since we have two half-spheres, the total surface area of the half-spheres is:

2(4πr²) = 8πr².

The cost of the half-spheres is three times more expensive than the cost of the cylindrical part. Let's say the cost per unit area of the cylindrical part is x, then the cost per unit area of the half-spheres is 3x.

The total cost, C, is the sum of the cost of the cylindrical part and the cost of the half-spheres. It can be expressed as:

C = x(2πrh) + 3x(8πr²) ...(2)

Now, we can minimize the cost by differentiating equation (2) with respect to either r or h and setting it equal to zero. This will help us find the values of r and h that minimize the cost. To simplify the calculations, we can rewrite equation (2) in terms of h using equation (1):

C = x(2πr(1000/πr²)) + 3x(8πr²) C = 2x(1000/r) + 24xπr² ...(3)

Now, differentiating equation (3) with respect to r:

dC/dr = -2000x/r² + 48xπr

Setting dC/dr equal to zero:

0 = -2000x/r² + 48xπr

Simplifying the equation:

2000x/r² = 48xπr

Dividing both sides by 4x: 500/r² = 12πr

Multiplying both sides by r²: 500 = 12πr³

Dividing both sides by 12π: 500/(12π) = r³

Simplifying: 125/3π = r³

Taking the cube root of both sides: r = (125/3π)^(1/3)

Now, we can substitute this value of r back into equation (1) to find the value of h:

1000 = π((125/3π)^(1/3))^2h

Simplifying: 1000 = (125/3π)^(2/3)πh

Dividing both sides by π and simplifying:

1000/π = (125/3π)^(2/3)h

Simplifying further:

1000/π = (125/3)^(2/3)h

Now we can solve for h: h = (1000/π) / ( (125/3)^(2/3) )

Simplifying: h = 11.99 m

To summarize, to minimize the cost of building the tank, the radius of the cylindrical part should be (125/3π)^(1/3) meters and the length of the cylindrical part should be approximately 11.99 meters.

Step-by-step explanation:

The odds in favor of obtaining a number divisible by 3 or 4 in a single roll of a die are 7:5 or 7/5.

The probability of obtaining a number divisible by 3 or 4 in a single roll of a die can be found by adding the probabilities of rolling 3, 4, 6, 8, 9, or 12, which are the numbers divisible by 3 or 4.

There are six equally likely outcomes when rolling a die, so the probability of obtaining a number divisible by 3 or 4 is:

P(divisible by 3 or 4) = P(3) + P(4) + P(6) + P(8) + P(9) + P(12)

P(divisible by 3 or 4) = 2/6 + 1/6 + 1/6 + 1/6 + 1/6 + 1/6

P(divisible by 3 or 4) = 7/12

The odds in favor of an event is the ratio of the probability of the event occurring to the probability of the event not occurring. Therefore, the odds in favor of obtaining a number divisible by 3 or 4 in a single roll of a die are:

Odds in favor = P(divisible by 3 or 4) / P(not divisible by 3 or 4)

Odds in favor = P(divisible by 3 or 4) / (1 - P(divisible by 3 or 4))

Odds in favor = 7/5

Step-by-step explanation:

A triangle is equal to 180°

The power of (1 - i√3)² is -2 - 2i√3 in rectangular form.

DeMoivre's Theorem states that for any complex number in polar form, (r(cosθ + i sinθ))ⁿ = rⁿ(cos nθ + i sin nθ).

To use DeMoivre's Theorem to find the power of (1 - i√3)² we first need to express it in polar form. We can do this by finding the magnitude and argument of the complex number:

Magnitude:

|(1 - i√3)| = √(1² + (√3)²) = √4 = 2

Argument:

arg(1 - i√3) = arctan(-√3/1) = -π/3 (since the complex number is in the third quadrant)

Therefore, we can write (1 - i√3) in polar form as 2(cos (-π/3) + i sin (-π/3)).

Now, using DeMoivre's Theorem, we have:

(1 - i√3)² = [2(cos (-π/3) + i sin (-π/3))]²

= 4(cos (-2π/3) + i sin (-2π/3))

= 4(-1/2 - i√3/2)

= -2 - 2i√3

Therefore, the power of (1 - i√3)² is -2 - 2i√3 in rectangular form.

(A) 60

(B) 70

(C) 80

(D) 50

Answer:

15 degrees

Step-by-step explanation:

So you know that the sum of the two angles is 90 degrees, so you can make an equation:

$3x+45=90$

Then, solve:

subtract 45 from both sides

$3x=45$

divide both sides by 3

$x=15$

This means that x = 15 degrees

Answer:

The answer is 15 degrees.

Step-by-step explanation:

1) Do you see the little square symbol at the bottom right corner? That represents that the angle is a right angle, or a 90 degree angle, in other words.

2) If you know that the first part of the angle is 45 degrees, as it is already labeled, then subtract 90 degrees - 45 degrees = 45 degrees, which is the angle that is left.

3) Set 3x equal to 45 degrees, and solve.

4) So, the equation is 3x = 45; divide by 3 on both sides to get x = 15 degrees.

Using the Central Limit Theorem, it is found that the sampling distribution will be approximately normal, with mean of -0.04 and standard error of 0.0423.

In this problem, for each sample, the mean and the standard error are given by:

$p_C=0.08,s_C=\sqrt{\frac{0.08(0.92)}{100}}=0.0271$

$p_A=0.12,s_A=\sqrt{\frac{0.12(0.88)}{100}}=0.0325$

Then, for the distribution of differences, we have that:

$p=p_C-p_A=0.08-0.12=-0.04$

$s=\sqrt{s_C^2+s_A^2}=\sqrt{{0.0271}^2+{0.0325}^2}=0.0423$

The probability that the laptop was tested, given that it is functional, is 0.95, or 95%.

Given that the laptop is usable, we need to assess the probability that it has been tested. Let T stand for the laptop's testing event and F stand for the laptop's functioning event. The probability of T given F is what we are looking for next, or P(T|F).

The Bayes theorem can be used to determine P(T|F):

P(T|F) = P(F|T) * P(T) / P(F)

where P(F|T) is the probability that a laptop will be tested (which is 0.95), P(T) is the likelihood that a laptop will be tested, and P(F) is the likelihood that a laptop will be functional (which is the total of the likelihoods of being functional and defective, i.e., 0.95 + 0.05 = 1).

Using the conditional probability formula, we can determine P(F|T):

P(F|T) = P(F and T) / P(T)

Since 95% of the laptops produced are tested and determined to be functional, we know that the probability of a laptop being functional and tested is 0.95.

Therefore:

P(F|T) = 0.95 / 0.95 = 1

Substituting into Bayes' theorem:

P(T|F) = 1 * 0.95 / 1 = 0.95

Therefore, the probability that the laptop was tested, given that it is functional, is 0.95, or 95%.
