Answer:
0.0066
Step-by-step explanation:
Given that:
Mean = 75
Variance
The standard deviation
The sample size n = 100
Using the Z table;
P(x > 83.7) = 1 - 0.9934
P(x > 83.7) = 0.0066
Thus, probability = 0.0066
what do you need help with
=6x+20
3(x+5)+(3x+5)
Solution:
=3x+15+3x+5
Answer: 1,000
First, you have to find how much 7.5% is coming out of 10,000. So in this case it's 750. Multiply 750 by 12 years. Thats 9000, you then subtract 9000 and 10,000 to get 1,000.
