You are baking cookies for your class. There are 23 total students in your class and you have baked 12 cookies. Write and solve
KonstantinChe [14]
(x cookies) / (23 students - (12/2) students) = 2 cookies per student
[x / (23 - 6)] cookies per student = 2 cookies per student
23 students * (2 cookies per students) - 12 cookies = x cookies
The "students" unit cancels
46 cookies - 12 cookies = x cookies
x cookies = 34 cookies

QUESTION 3 of 10: Stock returns vary from year to year. The more variance a stock displays the greater the potential risk. These
Dahasolnce [82]

Answer:

The variance of these investment returns is 74

Step-by-step explanation:

Given:

Series =  10, 30, 15, 5, 20

To Find:

variance of a series = ?

Solution:

The variance of the series = Var\left(X\right)=\sum _{i=1}^n\frac{\left(x_i-\bar{x}\right)^2}{n}

\bar{x} = \frac{10+30 +5+15 + 20}{5}

\bar{x} = \frac{80}{5}

\bar{x} =16

Now (x_i -\bar{x})^2 = (10 -16)^2 + (30 -16)^2 + (5 -16)^2 +(15 -16)^2 +(20 -16)^2

= (-6)^2 + (14)^2 + (-11)^2 + (-1)^2+ (-4)^2

= 36  + 196 +121 +  1+ 16

=  370

Now

Var\left(X\right)=\frac{370}{5} =  74
