Answer:
C. 0.98
Step-by-step explanation:
Let x be the mean of Company A and B annual profit and x/2 and y are standard deviation of Company A and B annual profit.
P(B<0) = 0.9*P(A<0)
P(Z<(0-x)/y) = 0.9*P(Z<(0-x)/(x/2))
P(Z<-x/y) = 0.9*P(Z<-2)
P(Z<-x/y) = 0.0205
x/y =2.04
Or y/x = 1 /2.05
y/x =0.49
Ratio of the standard deviation of company B annual profit to the standard deviation of company A annual profit =y/(x/2)
= 2*(y/x)
= 2*0.49
= 0.98

Expression
-------------------------------------
5x - 3x
-------------------------------------
Substitute x = 2
-------------------------------------
5 (2) - 3(2)
= 10 - 6
= 4

Answer:
B. $337.50
Step-by-step explanation:
1.5% of $22,500 is 337.5
Answer:
-74
Step-by-step explanation:
First you use term 0, which is 6 because term 1 is 4. The slope is -2x so after 40 terms it would be -74.
Answer:
a.) The values of y from
x = - 2 to x = 2 are
6
1
0
3
10
<h3>b.) The answer is curve B.</h3>
