D>7

To write an inequality means to write an expression where one side is greater than the other, or less than the other. In this case, we are to write an inequality that shows that John will have more than 7 dollars in his bank account. The variable we are to use is d, which will represent the number dollars in his bank account. If he wants to have more than seven dollars, then d will have to be greater than seven.

The cable company takes an simple random sample of 250 of the approximately 15,000 households who subscribe to them. They found

finlep [7]

Answer:

The standard deviation of the sampling distribution of p is 0.03.

Step-by-step explanation:

According to the Central limit theorem, if from an unknown population large samples of sizes <em>n</em> > 30, are selected and the sample proportion for each sample is computed then the sampling distribution of sample proportion follows a Normal distribution.

The mean of this sampling distribution of sample proportion is:

$\mu_{\hat p}=p$

The standard deviation of this sampling distribution of sample proportion is:

$\sigma_{\hat p}=\sqrt{\frac{p(1-p)}{n}}$

It is provided that, a cable company takes an simple random sample of 250 of the approximately 15,000 households who subscribe to them to determine the proportion of households that watch sports on television at least once a month.

The actual proportion is 70%.

As the sample selected is quite large, i.e. <em>n</em> = 250 > 30, the central limit theorem can be used to approximate the sampling distribution of sample proportions.

Compute the standard deviation of this sampling distribution as follows:

$\sigma_{\hat p}=\sqrt{\frac{p(1-p)}{n}}$

$=\sqrt{\frac{0.70(1-0.70)}{250}}\\\\=0.0289828\\\\\approx 0.03$

Thus, the standard deviation of the sampling distribution of p is 0.03.

Find output value of s.

Brrunno [24]

Considering the value of the equation after each iteration of the loop, the output value of s is 25.

<h3>What is the value of s after each iteration?</h3>

We have that i ranges from 1 to 3, and from each value of i, j ranges from 1 to 1. s starts at 0, hence, for each iteration, the value of s is found as follows. The output value is the value after the last iteration.

i = 1, j = 1: s = 0 + 1 x 1 = 1.

i = 2, j = 1: s = 1 + 2 x 1 = 3.

i = 2, j = 2: s = 3 + 2 x 2 = 7.

i = 3, j = 1: s = 7 + 3 x 1 = 10.

i = 3, j = 2: s = 10 + 3 x 2 = 16.

i = 3, j = 3: s = 16 + 3 x 3 = 25.

The output value of s is of 25.

The volume of a cylinder is 1,0291 cubic centimeters. The height of the cylinder is 21 centimeters. What is the radius, to the n

boyakko [2]

Answer:

12.49 = r

13 = r to the nearest cm.

Step-by-step explanation:

The formula to calculate the volume is:

V = π*r^2*h

We know that V = 10291 cm^3 and Height (h) = 21cm

V = π*r^2*h

10291 = π*r^2*21

Divide both side by 21

10291/21 = (π*r^2*21)/21

490.05 = π*r^2

Now divide both side by π

490.05/π = (π*r^2)/π

155.99 = r^2

Now square root both side

√155.99 = √(r^2) Note: square and square root cancel eachother out.

12.49 = r or,

13 = r
