4) The prices of various cereal boxes is normally
distributed with a standard deviation of 0.5. If a
box of Lucky Charms sells for $4.29 and has a z-
score of 1.6, what is the mean price of a box of
cereal?

$3.49

Step-by-step explanation:

-The z value is calculated by the formula:

Where are the mean and standard deviation respectively and is the price of the random selection.

#We substitute and solve for :

Hence, the mean price of a box of cereal is $3.49

f(x) = x^3 -2x^2 -3x

x( x^2 -2x-3)

x( x^2 +x -3x -3)

x( x(x+1) -3(x+1))

x( x-3)( x+1)

so zeroes are 0, 3,-1
