The mean return/year and the standard deviation are given below.
u= $300,
0 = $1000.
Suppose the company insures four houses with returns designated by X1, X2, X3, and X4.
Let Z be the average of the four returns; that is,
7
X1 + X2 + X3 + X4
(a) Find uz.

Given the equation f(x)=a(b)x where the initial value is 40 and the growth rate is 20% what is f(4)

Michelle and julie work at a catering company. they need to bake 264 cookies for a birthday party that starts in a little over an hour and a half. each tube of cookie dough claims to make 36 cookies, but michelle eats about 1/5 of every tube and julie makes cookies that are 1.5 times as large as the recommended cookie size.it takes about 8 minutes to bake a container of cookies, but since julie's cookies are larger, they take 12 minutes to bake. a. how many tubes should each girl plan to bake? how long does each girl use the oven? b. explain your solution process what did you make? c. what assumptions did you make?
