Answer:
A. 0.3204 B. $14.669
Explanation:
Mean = 8.9 SD = 4.5
Required probability = P (X >/= 550/50)
P(X>/=11) = 1 - P[(X - mean/SD) < (11 - mean)/SD]
= 1 - P(Z < (11-8.9)/4.5)
P(X>/=11) = 1 - P(Z < 0.4666667)
Using Excel NORMDIST(0.4666667,0,1,1)
P(X>/=11) = 1 - 0.6796 = 0.3204
The probability that she will earn at least $550 = 0.3204
b. P
(
X > x
) = 0.10
1 − P
(
X − mean)/SD ≤ (x − mean)
/SD = 0.10
P
(
Z ≤ z
) = 0.90
Where,
z = (x − mean
)/SD
Excel function for the value of z:
=NORMSINV(0.9)
=1.282
Hence (x - mean)/SD = 1.282
= (x - 8.9)/4.5 = 1.282
x = (1.282*4.5) + 8.9
x = 14.669
He earns $14.669 on the best 10% of such weekends.

Explanation:
To begin with, the total manufacturing costs variance is the concept known in the field of business and that is comprehended in the accounting field that involves and cosists of direct materialsl costs variance, direct labor costs variance and factory overhead costs variance. And therefore that it implicates the difference between what actually all that variables end up costing and what the company thought that it will cost regarding their standards given.
Answer: $3865.8
Explanation:
The formula to find the simple interest is given by :-
, where P is the initial amount deposited , r is the rate of interest in decimal and t is the time period in years.
Given : P= $1700 ; r= 9.8%=0.098 ; t=13 years
Then , the simple interest earned in 13 years will be :-
Now, the combined amount = P+I =$1700+$2165.8= $3865.8
Hence, the credit union would owe Heather $3865.8 in 13 years.
