Step-by-step explanation:

it is given in question that

sample space n=34

μ the population mean =120

the sample mean $\bar{x}=115$

the population standard deviation σ=20

we have to find the null hypothesis and alternative hypothesis

null hypothesis

the average braking distance for a small car travelling at 65 miles per hour equals to 120 feet

so $H_{\0}:\mu =120$

Alternative hypothesis

the average braking distance for a small car travelling at 65 miles per hour not equals to 120 feet

so $H_{\0}:\mu \neq 120$

Answer:

70. 8x⁴

71. 3n - 10

72. a/5 + 12

Step-by-step explanation:

70. a number "x" raised to the fourth = x⁴

Product of 8 and x⁴ = 8 × x⁴

= 8x⁴

71. 3 times a number "n" = 3 × n = 3n

3n decreased by 10 = 3n - 10

72. Quotient of a number "a" and 5 = a/5

12 more than a/5 = a/5 + 12
