Exercise #4 The number of calories in a 1-ounce serving of a certain breakfast cereal is a random
variable with mean 110 and standard deviation 10. The number of calories in a cup of
whole milk is a random variable with mean 140 and standard deviation 12. For
breakfast, you eat 1 ounce of the cereal with 1/2 cup of whole milk. Let T be the
random variable that represents the total number of calories in this breakfast.
The standard deviation of T is... be sure to show/explain
your reasoning!

Step-by-step explanation:

:)

25 questions , because they start with 100.  

350-100=250 .  

. 250/10=25

step-by-step explanation:

first take off 100, then what x 10 = 250? that is your answer. (25)

d 25 pi/6

step-by-step explanation:

the diameter is 10 inches

the radius is 1/2 of the diameter or 5 inches

the area of the circle is

a = pi r^2

  = pi 5^2

  = 25 pi

the slice is 60 degrees of the entire circle.

60 degrees out of 360   60/360 = 1/6

the area of the slice is 1/6 of the circle

a slice = 1/6 a circle

a slice = 1/6 * 25 pi
