Answer:
3.93% probability that both say service is poor
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
The customers are chosen without replacement, and the order in which they are chosen is not important. So we use the combinations formula to solve this question.
Combinations formula:
is the number of different combinations of x objects from a set of n elements, given by the following formula.
What is the probability that both say service is poor?
Desired outcomes:
Two saying it is poor, from a set of 66. So
Total outcomes:
Two customers from a set of 331. So
Probability:
3.93% probability that both say service is poor
Answer:
O=30° or O=29°
Step By Step Explanation:
∠α =arcsin( a/c )
= arcsin(4/8)
= arcsin(0.5)
= 0.5 rad = 30° = 29°
I Hope This Helps. I Gave you 2 answers just in case 1 is Wrong. And I Hope you Understand This Calculation, I Used Different Variables and the arcsin thing is something my teacher told my class to use, and I Have no Idea what it means because my teacher never explained what it meant, Sadly.

Answer:
$95.5090 must be deposited monthly
Step-by-step explanation:
From the information given:
The annual interest rate (r) = 4.2% = 0.042
Let assume that an amount Y is deposited, then after one month, it will increase to:
The total amount after 4 years will be:
Using the sum of a geometric progression:
The above amount is then equal to $5000
i.e
