Answer:

B. the mean

Step-by-step explanation:

According to the Bar Chart shown, the number of DVDs sold at a local music store during one week are displayed.

Therefore, the measure(s) of central tendency that can be used to determine the average number of DVDs sold each day is the mean.

This is because the mean is the sum total of the number of DVDs sold, divided by the number, which gives the average.

Bingel [31]

Answer:

$80.15

Step-by-step explanation:

We can make an equation to solve this problem, that helps a lot. If h represented hours, we could make the equation 15.53h+s=157.8

Now we know that he worked 5 hours, so we can multiply 15.53 by 5 to simplify the equation.

15.53*5=77.65

So now the equation is 77.65+s=157.8.

Now, we can subtract 77.65 from both sides.

So now, our final equation is s=80.15

It cost $80.15 to buy supplies.

Hope this helps!

What is the answer of it

polet [3.4K]

The correct answer is A. 15,200.00

Explain

E= 1 -x/p

X= 293

P= 473 k

E= 1 -x/p = 1 - 293/473. = 0.38

So now E= 0.38 —> 38%

40, 000,000 x 0.38 = 15, 200, 000

Hope this help you

Using the z-distribution, as we are working with a proportion, it is found that the margin of error for the 90% confidence interval is of 0.0524 = 5.24%.

<h3>What is a confidence interval of proportions?</h3>

A confidence interval of proportions is given by:

$\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}$

In which:

$\pi$ is the sample proportion.

z is the critical value.

n is the sample size.

The margin of error is given by:

$M = z\sqrt{\frac{\pi(1-\pi)}{n}}$

In this problem, the critical value is given as z = 1.645, and since 26 out of 80 students said they would be willing to pay extra:

$n = 80, \pi = \frac{26}{80} = 0.325$

Then, the <em>margin of error</em> is of:

$M = 1.645\sqrt{\frac{0.325(0.675)}{80}} = 0.0524$

A circle in the XY-plane has center (5, 7) and radius 2. Which of the following is an equation of the circle?

MAXImum [283]

Answer: A, because the equation of a circle is $(x-h)^2+(y-k)^2=r^2$ . So, if the point of the center is $(5,7)$ and the radius $2$ , then on the equation should be changed as negative and the radius should be multiplied as $4$ , which is $(x-5)^2+(y-7)^2=4$
