Answer:
It is 4.3
Explanation:
because 15.7 minus 11.4 is equal to 4.3.
This is the equation g of h. It means that h(g(x). Wherever there is an x input g(x).
h(g(x))= 3-(4-3x)^2
The probability that the sample mean would differ from the population mean by less than 655 miles in a sample of 79 tires if the manager is correct is = 0.9805.
<h3>
What is the calculation for the above?</h3>
P (
< 655) ≡ P [ |(
- μ)/√(σ²/n) | <655/√(6,220,036/ 79)]
= P (| Z | < 3.55)
= P - 3.55 < Z < 3.55) Using the z -score table
= 0.9998 - 0.0193
= 0.9805

Answer: 10
Explanation:
When the number removed, the mean change from 12 to 11, so we assume that the removed number, x, has related to the median.
To find the removed number x, we sat their average equal to 11.
(12 + x) /2 = 11
12 + x = 22
x = 10
