Answer: 28/3 hours

Step-by-step explanation:

From the question, Kim and Josh can clean a house together in 3 hours while Kim alone uses 7 hours to clean the house by herself.

Kim's hourly rate will be to clean the house = 1/7 per hour.

In 4 hours:

Kim will have completed = 1/7 × 4 = 4/7 of the house

This mean that Josh completes:

1 - 4/7 = 3/7 of the house.

Josh's hourly rate will now be:

1/4 × 3/7 = 3/28 of the house per hour.

From Josh to clean the house alone, he will use:

= 1 ÷ (3/28)

= 1 × 28/3

= 28/3 hours

Josh will use 28/3 hours to clean the house alone?

The rectangle has a height of 222 and a width of 5x^2 - 2x + 35.

To find the area of the rectangle, we multiply the height by the width. Let's substitute the given values:

Area = height * width

Area = 222 * (5x^2 - 2x + 35)

To simplify the expression, we can distribute the 222 to each term within the parentheses:

Area = 222 * 5x^2 - 222 * 2x + 222 * 35

Now, let's further simplify each term:

Area = 1110x^2 - 444x + 7770

The requirement that we are strictly failing when using the critical z value is the knowledge of the population standard deviation.

The problem with calculating the confidence interval using the critical z value is that it assumes the population standard deviation is known.

This assumption is often not realistic because in most cases, the population standard deviation is unknown and needs to be estimated from the sample data.

When the population standard deviation is unknown, it is more appropriate to use the t-distribution instead of the standard normal distribution (z-distribution) to calculate the confidence interval.

The t-distribution takes into account the uncertainty introduced by estimating the population standard deviation from the sample.

Therefore, the requirement that we are strictly failing when using the critical z value is the knowledge of the population standard deviation.

y= -3x+2

Step-by-step explanation:

Parallel lines have the same slope. We can form an incomplete equation:

y= -3x+b

(make sure to see why the slope is -3)

We can plug in the coordinates of (2, -4):

-4= -3(2)+b

-4= -6+b

2=b

b is 2! We can form an equation: y= -3x+2

The arc length of the curve y = (1/3)x^(3/2) on [0,60] is approximately 137.78 units.

For the arc length of the curve y = (1/3)x^(3/2) on [0,60], we can use the formula:

L = ∫[a,b] √(1 + [f'(x)]²) dx

where f(x) = (1/3)x^(3/2) and a = 0, b = 60.

We first need to find f'(x):

f'(x) = d/dx [(1/3)x^(3/2)] = (1/2)x^(1/2)

Now we can plug this into the formula:

L = ∫[0,60] √(1 + [(1/2)x^(1/2)]^2) dx

 = ∫[0,60] √(1 + (1/4)x) dx

To evaluate this integral, we can use the substitution u = 1 + (1/4)x, du/dx = 1/4, which gives us:

L = 4 ∫[1/4,16] √u du

 = (8/3) [u^(3/2)] [1/4,16]

 = (8/3) [(16^(3/2) - (1/4)^(3/2))]

 ≈ 137.78

Therefore, the arc length of the curve y = (1/3)x^(3/2) on [0,60] is approximately 137.78 units.

The work of  5/6 more than 360 is equal to 660.

To calculate what 5/6 is out of 360, you can use the following steps:

Divide 360 by 6 (the denominator of the fraction) to determine the value of 1/6.

360 / 6 = 60 Multiply the value of 1/6 by the numerator (5) to find the value of 5/6.

60 * 5 = 300

Step 1: Calculate 5/6 of 360.

To find 5/6 of a number, you multiply that number by the fraction 5/6. In this case, we want to find 5/6 of 360. To do that, we multiply 360 by 5/6:

(5/6) * 360 = (5 * 360) / 6 = 1800 / 6 = 300

So, 5/6 of 360 is equal to 300.

Step 2: Add the result to 360.

To find 5/6 more than 360, we take the result from Step 1, which is 300, and add it to 360:

300 + 360 = 660

Therefore, 5/6 more than 360 is equal to 660.

In summary, by calculating 5/6 of 360, we found that it is 300. Adding 300 to 360 gives us the final result of 660, which represents 5/6 more than 360.

The simple random sample provided a sample mean of X and a sample standard deviation of Y.

A simple random sample is a subset of individuals selected randomly from a larger population. The sample mean (X) represents the average value of the variable of interest within the sample, while the sample standard deviation (Y) measures the dispersion or spread of the data around the sample mean. The sample mean is calculated by summing up all the values in the sample and dividing it by the sample size. The sample standard deviation is calculated by taking the square root of the variance, which is the average of the squared differences between each value and the sample mean.

The sample mean is a useful statistic as it provides an estimate of the population mean, assuming the sample is representative of the population. It is often used to make inferences about the larger population. On the other hand, the sample standard deviation indicates the variability within the sample. A smaller standard deviation suggests that the data points are closer to the sample mean, while a larger standard deviation indicates greater variability or dispersion.

It is important to note that the sample mean and sample standard deviation are statistics calculated from the sample and are subject to sampling variability. To make more accurate inferences about the population, it is often necessary to use inferential statistics, such as confidence intervals or hypothesis testing. These techniques take into account the sample size, sample mean, and sample standard deviation to draw conclusions about the population parameters.

Overall, the simple random sample provided a sample mean of X and a sample standard deviation of Y, which are essential measures to understand the central tendency and dispersion of the data within the sample.

The answer is dR/dt = -8f(10).

The equation linking the price p and the quantity demanded q is given by p2+2q2=1100.

The expression of R in terms of p and q is given by:

R = pq.

Now, we have that dR/dt can be expressed as:

dR/dt=A dp/dt,

where A is a function of just q.

To determine A, we use the chain rule of differentiation.

Differentiate both sides of the equation p2+2q2=1100 with respect to time t and use the fact that

dp/dt = 2p dp/dq - 4q.

Then, we have:

d(p2 + 2q2)/dt

= d(1100)/dt2p dp/dt + 4q dq/dt

= 0dp/dt

= (-2q/p) dq/dt

Therefore, dR/dt = A (-2q/p) dq/dt

We know that A is a function of just q.

Since A is a function of q, we can express it as A = f(q).

Substituting this into the equation above, we have:

dR/dt = (-2f(q)q/p) dq/dt.

When q = 10, and dp/dt = 4,

we need to determine p.

To do this, substitute the value of q into the equation:

p2 + 2q2 = 1100.

Thus,p2 + 2(10)2 = 1100 => p = 10 square root of 6.

The derivative of R = pq is dR/dt = p dq/dt + q dp/dt.

Substituting values of q, p, and dp/dt, we have:

dR/dt = (-2f(10)(10 square root of 6)/(10 square root of 6)) (4)

= -8f(10).

We cannot say that the antiderivative of sign(x) is abs(x). Instead, the antiderivative of sign(x) is x*abs(x)/2 + C, where C is the constant of integration.

Here's a step-by-step explanation:
Step:1. Recall that the antiderivative (or integral) represents the function whose derivative is the given function. In this case, we need to find the antiderivative of sign(x).
Step:2. Consider the three cases of sign(x) separately: x < 0, x = 0, and x > 0.
Case 1: x < 0
- sign(x) = -1, so we need to find the antiderivative of -1. The antiderivative of -1 is -x + C1, where C1 is the constant of integration.
Case 2: x = 0
- sign(x) = 0, so the antiderivative is simply C2, where C2 is the constant of integration.
Case 3: x > 0
- sign(x) = 1, so we need to find the antiderivative of 1. The antiderivative of 1 is x + C3, where C3 is the constant of integration.
Step:3. Combine the three cases using the absolute value function:
Antiderivative of sign(x) = x * abs(x) / 2 + C
In this expression, C is the constant of integration, and the term x*abs(x)/2 accounts for the three cases of sign(x) with their respective antiderivatives.
