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 = 
Now 
= 
= 36 + 196 +121 + 1+ 16
= 370
Now
= 74
Answer:
x=2 f(x)=5-x
o≤x≤3 f(x)=x
2＜x＜3 f(x)=1
3＜x≤5 f(x)=5-x
Step-by-step explanation:
Answer:
Lies in the shaded regions of both the top and bottom inequalities.
Step-by-step explanation:
The point of solution for BOTH systems of inequalities must work for both equations. Therefore, the point has to lie in both top and bottom shaded regions or it won't work for both, but just one.
Answer:
<em>The expression is equal to 22</em>
Step-by-step explanation:
<u>Expression Evaluation</u>
We are given the expression
10 + 2p - 3r
And it's required to evaluate it when p=3 and r=2. This means we have to replace the letter for the value assigned to them, as follows:
10 + 2*3 - 3*(-2) = 10 + 6 - (-6)
= 10 + 6 + 6
= 22
The expression is equal to 22
