I agree...C is the answer.  Anytime you put in a value for X, you get a different Y answer, so yes, there are many answers.  The other answer gives you two examples using x = 5 and x = 10.  You could also substitute any other number for x and get a different y answer; an infinite number of x's and y's actually.

A researcher selects all of the possible samples with n = 8 scores from a population and computes the mean, dividing by n, for e
Nadusha1986 [10]

Answer:

By the Central Limit Theorem, the average value for all of the sample means is 14.

Step-by-step explanation:

We use the central limit theorem to solve this question.

The Central Limit Theorem estabilishes that, for a random variable X, with mean \mu and standard deviation \sigma, the sample means of size n can be approximated to a normal distribution with mean \mu and standard deviation, which is also called standard error s = \frac{\sigma}{\sqrt{n}}

If the population mean is μ = 14, then what is the average value for all of the sample means?

By the Central Limit Theorem, the average value for all of the sample means is 14.

Can a triangle be formed with the side lengths of 2.9 in, 4.8 in, and 7.4 in?
ddd [48]

Answer: Yes

Step-by-step explanation: A triangle can be formed because A+B>C

A and B are 2.9 and 4.8

Since those numbers have the least value

I added both and found that A and B are equal to 7.7

7.7>7.4

These sides could form a triangle

What is the area of the shaded region plzz help
Aneli [31]

Answer:

78.10 cm^2

Step-by-step explanation:

The area of the shaded region is the area of the rectangle subtracted from the area of the circle.

area of circle = (pi)r^2

area of rectangle = LW

shaded area = area of circle - area of rectangle

shaded area = (pi)r^2 - LW

shaded area = (pi)r^2 - LW

shaded area = (3.14159)(6 cm)^2 - (7 cm)(5 cm)

shaded area = (3.14159)(36 cm^) - 35 cm^2

shaded area = 113.097 cm^2  35 cm^2

shaded area = 78.097 cm^2

Answer: 78.10 cm^2
