The weight of apples selected at random from a bin at the local farmers market is a random variable with mean m = 12 ounces and standard deviation s = 1 ounce. If 5 apples were selected what would be the expected weight and standard deviation of all 5 apples together?

A. Mean of 12 ounces with a standard deviation of 1 ounces
B. Mean of 60 ounces with a standard deviation of 5 ounces
C. Mean of 60 ounces with a standard deviation of 2.236 ounces
D. Mean of 12 ounces with a standard deviation of 2.236 ounces

y = 2x

step-by-step explanation:

if you divide each number in the sequence, you'll see that they all have a multiple factor of 2. each number in the series, and any other numbers which may continue, will be multiplied by 2. therefore, y is the next number in the sequence, and x is the current one, so, our formula will be y = 2x.

step-by-step explanation:

n=9

step-by-step explanation:

7 times a number = 7n

decreased by 13 = 7n-13

same as is =

5 times the number = 5n

increased by 5 = 5n+5

7n-13 = 5n+5

2n=18

n=9

m∠a is 90°
