The answer of the question is x.
Answer:
Distance of point P(3,0) from x axis is zero as this point lies on x axis.
distance of point Q is 3.
Distance of point R is 4.
Distance of point S is 3.
Step-by-step explanation:
Point P already lies on x axis as its y coordinate is zero so its distance from x axis is zero
distance of points Q , R and S is the absolute value of their y coordinates that is 3 , 4 and 3 respectively.

Step-by-step explanation:
Answer:
Yes, we reject the auto maker's claim.
Step-by-step explanation:
H0 : μ ≥ 20
H1 : μ < 20
Sample mean, xbar = 18 ;
Sample size, n = 36
Standard deviation, s = 5
At α = 0.01
The test statistic :
(xbar - μ) ÷ s /sqrt(n)
(18 - 20) ÷ 5/sqrt(36)
-2 /0.8333333
= - 2.4
Pvalue from test statistic : Pvalue = 0.00819
Pvalue < α
0.00819 < 0.01
Hence, we reject the Null
I believe it is going to be 60
