Answer:  The midpoint of the points A(-4, 2) and B(8, 5) is M(2, 3.5).

Step-by-step explanation:  We are given to find the midpoint of the points A(-4, 2) and B(8, 5).

We know that

the co-ordinates of the midpoint of the points (a, b) and (c, d) are given by

M=\left(\dfrac{a+c}{2},\dfrac{b+d}{2}\right).

Therefore, the co-ordinates of the midpoint of the points (-4, 2) and B(8, 5) will be

M=\left(\dfrac{-4+8}{2},\dfrac{2+5}{2}\right)=\left(\dfrac{4}{2},\dfrac{7}{2}\right)=(2,3.5).

Thus, the midpoint of the points A(-4, 2) and B(8, 5) is M(2, 3.5).

Mileage tests are conducted for a particular model of automobile. If a 98% confidence interval with a margin of error of 1 mile
Llana [10]

Answer: 37

Step-by-step explanation:

Given : Significance level : \alpha:1-0.98=0.02

Critical value : z_{\alpha/2}=z_{0.01}=2.33

margin of error : E= 1 mile per gallon

Population standard deviation: \sigma=2.6 miles per gallon.

We know that when the population standard deviation is known then the formula to find the sample size is given by  :

n=(\dfrac{z_{\alpha/2}\times \sigma}{E})^2

n=(\dfrac{(2.33)\times 2.6}{1})^2=36.699364\approx37  [Round to the next whole number.]

Hence, the required number of automobiles should be used in the test = 37
