Answer:
A)1050
B)8050
Step-by-step explanation:
to find interest we use the formula A= P(1+rt) where P is the initial investment, r is the rate percent, and t is the time interval
for this question we have A=7000(1+3(5)) which gives 8,050 dollars which is the answer to part B
for part A we simply subtract the answer from B from the initial investment so 8050 - 7000 = 1050 made from interest
Answer:
31.42ft
Step-by-step explanation:
diameter = 10
radius = diameter ÷ 2
r = 10 ÷ 2
r= 5
Circumference = 2(pie)(r)
= 2(22÷7)(5)
= 31.42ft
Answer:
The required probability is 0.94
Step-by-step explanation:
Consider the provided information.
There are 400 refrigerators, of which 40 have defective compressors.
Therefore N = 400 and X = 40
The probability of defective compressors is:

It is given that If X is the number among 15 randomly selected refrigerators that have defective compressors,
That means n=15
Apply the probability density function.

We need to find P(X ≤ 3)


Hence, the required probability is 0.94
Answer:
A
Step-by-step explanation:
12*3 = 36 = A
Hey hey!
56 would be the answer.
WAIT, don’t leave just yet! You have to show at least some work! You CANT learn if you don’t know what you’re doing.
Here’s how I got the answer:
7:4 walls = 10:8 people =M:40 minutes
M = (7/4) / (10/8) x 40
M = 56 minutes.
