The number of calories in peanut m& ms have an approximately normal distribution with mean 10 calories per m& m and variance 4. what percentage of peanut m& ms are more than 15 calories

0.62%

Step-by-step explanation:

Given : The number of calories in peanut M&Ms have an approximately normal distribution with

Standard deviation :

Let x be the amount of calories in a randomly selected peanut M&Ms.

Z-score :

The probability that the peanut M&Ms are more than 15 calories using standardized normal distribution table  :

In percent ,

Hence, the  percentage of peanut M&Ms are more than 15 calories is 0.62%.

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

answer:

f(5/2) = 10/3

i hope this you!
