Answer:
Sam has the more convincing victory with a greater Zscore value
Step-by-step explanation:
Given that :
Year 1:
Mean finish time (m) = 185.64
Standard deviation (s) = 0.314
Sam's time (x1) = 185.29
Year 2:
Mean finish time (m) = 110.3
Standard deviation (s) = 0.129
Rita's time (x1) = 110.02
Zscore = (x - mean) / standard deviation
Sam's Zscore :
(185.29 - 185.64) / 0.314
= - 0.35 / 0.314
= −1.114649
= - 1.115
Rita's Zscore :
(110.02 - 110.3) / 0.129
= - 0.28 / 0.129
= −2.170542
= - 2.171
Sam has the more convincing victory with a greater Zscore value
You add them up to see that it is in fact greater...
12.6+3.1+5.4=
21.1
Answer:
The first graph
Step-by-step explanation:
when x is equal to something it is always up
y = 2 would be #4
The answer is the first one
Answer:
q = -3.
Step-by-step explanation:
By the Remainder Theorem:
Remainder when dividing by x + 2 = g(-2) and
the remainder when dividing by x - 1 = g(1) .
So g(-2) = g(1) .
That is:
2(-2)^3 + 3(-2)^2 - 2q - 1 = 2(1)^3 + 3(1)^2 + q - 1
-16 + 12 - 2q - 1 = 2 + 3 + q - 1
-2q - q = 5 + 2 + 3 - 1
-3q = 9
q = -3.
