Answer:
(a) is 4*C and (B) is 16*C
9 is A. To find y set x equal to zero. To find x set y equal to zero.
10 is D. I found the slope of the two points. Slope is y1-y2 / X1-x2
Answer:
H0 : μ = 4.50
H1 : μ > 4.50
Test statistic = 1.525
we conclude that there is no sufficient evidence to conclude that the mean wait time for customers is longer than 4.50.
Step-by-step explanation:
H0 : μ = 4.50
H1 : μ > 4.50
Test statistic :
(xbar - μ) ÷ s/sqrt(n)
(4.94 - 4.50) ÷ 2.10/ sqrt(53)
0.44 / 2.10/ sqrt(53)
= 1.525
α = 1 - 98% = 0.02
Decision region :
Reject H0 ; if Pvalue < α
Pvalue = p(Z < 1.525) = 0.936
Pvalue = 0.936
Since Pvalue > α ; We fail to reject H0
Hence, we conclude that there is no sufficient evidence to conclude that the mean wait time for customers is longer than 4.50.
Answer:
180 degrees are in a triangle.
B. 1 = 12
i + (-3) is really just i - 3
i - 3 = 9
add 3 to both sides since the opposite of -3 is +3
you’re left with i = 12
