Answer: The percent higher is 41.68%. If 49 planes were selected, 20 of them should be above 15 years.
To find the percent, we first need the z-score.
(15 - 13.5) / 7.3 = 0.21
Now, use a normal distribution table to find the percent above a score of 0.21. It will be 41.68%.
To find the number of 49 planes above this value, multiply 49 by 0.4168. You will have about 20.4 planes.
Y=4/5x hope that’s the right answer
Hi,
Divide using Copy Dot Flop,
2/3 ÷ 4/5 = 2/3 x 5/4
Multiply,
2 x 5 = 10
3 x 4 = 12
= 10/12
Simplify,
10/12 = 5/6
Answer - 5/6
