Answer:
Step-by-step explanation:
a. P(Z > 1.12) = 1-N(1.12) = 1-0.8686431=0.1313569
b. <em>P(Z S-2.35)</em> => P(Z <= 2.35) = 0.009386706
(please check interpretation of question b)
c. <em>POSZ s 1.34)</em> => P(0 <= Z <= 1.34) = 0.9098773 - 0.5 = 0.4098773
(please check interpretation of question c)
d. P(-0.8 sz s 2.44) => P(-0.8 <= 2.44) = 0.9926564 - 0.2118554 = 0.780801
(please check interpretation of question d)
Answer:8.3 repeating
Step-by-step explanation
First, subtract 47 by 32.
Then, multiply that difference by 5/9.
For ex:
47-32=15
15 x 5/9=8.3333333 and so on

Answer:</h3>
7 months
<h3>
Step-by-step explanation:</h3>
After Carter makes his $500 payment, the balance on the loan is -1596.37. We want to find the number of months (m) such that ...
... -1596.37 +250m ≥ 0
... m ≥ 1596.37/250 . . . . add 1596.37, divide by the coefficient of m
... m ≥ 6.4
The least number of months that is more than 6.4 is 7 months.

Carter's loan balance may also be affected by interest charged on the loan amount. We don't expect those charges to be so high as to require an additional month's payment.
