If you randomly purchase one item, the probability it will last longer than 9 years is; 11.12%
<h3>How to find the probability from z-score?</h3>
The formula for Z-score is;
z = (x' - µ)/σ
where;
x' = sample mean
µ = population mean
σ = standard deviation
Thus;
z = (9 - 7.9)/0.9
z = 1.22
From online p-value from z-score calculator, we have;
probability = 0.1112 = 11.12%

Hello!
You have to add how many trials he did
41 + 19 + 28 + 12 = 100
Now you look for the box that has 6 and tails
It has a 12 in it
You do 12/100
This can be reduced to 3/25
The answer is A
Hope this helps!
(190,258.50 + 152,698.00 + 122,753.00 + 220,523.00 + 231,951.00) : 5 = 183,636.70 - answer.
Answer:
9
Step-by-step explanation:

Answer:
tan(C) = √3/√2
Step-by-step explanation:
First, using Pythagorean Theorem, find AC.
=> AC = √(3√5)² - (3√3)²
=> AC = √45 - 27
=> AC = √18
=> AC = 3√2
tan C = 3√3/3√2
= √3/√2
