Answer:
ED = 26
Step-by-step explanation:
Using tangent-secant theorem
(12)²=(8)(x+10)
144=8x+80
144-80=8x
8x = 64
x=8
Now
ED = 8+8+10
ED = 26
If the sales representative is able to get 20% of the prospective customers to subscribe, the maximum expected number of subscriptions per week is
34. If the sales representative earns $3 per subscription in addition to daily wages, the minimum expected value of the extra income per week is
$94.20.
For the first answer, refer to the attached solution. Add the data each week, then multiply the sum by 20% to find out which has the maximum expected number of subscriptions.
For the second answer, the minimum expected value in week 2 multiplied by $3 to get the minimum expected value of the extra income in that week.
The z-score is given by:
Z-score=(x-μ)/σ
where:
μ=mean
σ=std deviation
From the information:
mean for 20-29 year old man is μ=69.669 and std deviation is σ=3.23
mean for 20-29 year old woman is μ=64.564 and the std deviation is σ=3.83
the z-score for 75 inch men is:
z-man=(75-69.669)/3.23=1.651
the z-core for 70 inch woman:
z-woman=(70-64.564)/3.83
=1.42
From the above we conclude that the z-score for the man is relatively larger than that of the women, this means that the man is taller.
The answer is A.
The second value in a set of parenthesis is the y value, so B is true.
If you multiplied each value of W by -2, you would get the values for V, so C is also true.
The answer is B and C.
