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
Answer:
ABC is similar to EDC and Angle A is congruent to angle C. Width of lake is 48
Step-by-step explanation:
Answer:
(D)Events A and B are dependent, because P(B)≠P(B|A).
Step-by-step explanation:
<u>Definition:</u> Two events are independent if

An experiment consists of rolling a standard six-sided die once.
Event A is "rolling an even number"
Even numbers are 2,4 and 6
Event B is "rolling a 2."

Substitution into 
Left Hand Side =1/6
Right Hand Side =(1/6)÷(1/2)=1/3
Since
, therefore
which makes the events dependent.
