Answer:
530.66 in.²
Step-by-step explanation:
Area of a circle = πr²
In the circle above, the diameter is given. To find the radius, you divide the diameter by 2, i.e.
Radius(r) = 
= 13 in.
∴Area of the circle = 3.14 × 13²
= 3.14 × 169
= 530.66 in.²

Answer:
The mean birth weight for the sampling distribution is
3,500 grams.
Step-by-step explanation:
The sample mean is the average of the sample values collected divided by the number of the samples, while the population mean is the average or mean of all the values in the population. If the sample is random and the sample size is large enough, then the sample mean would be a good estimator of the population mean. This implies that with a randomly distributed and unbiased sample size, the sample mean and population mean will be equal, according to the central limit theorem. Therefore, the mean of the sample means will always approximate the population mean.
First, let's multiply 86.50 by 20 since she deposited $86.50 each month for 20 months.
86.50 * 20 = $1,730
Now, we have to divide this by 24.50 * 20 to find how much out of her $1,730 that she used on singing lessons.
24.50 * 20 = $490
Subtract how much she used for singing lessons from her total amount.
1,730 - 490 = $1,240
Finally, we multiply the amount she has left by 1/4 to find out how much she spent on her summer camp. We can also do this by multiplying 1,240 by 0.25 since 0.25 = 1/4.
1,240 * 0.25 = $310
So, Molly spent $310.00 on her summer camp.
