Answer:
a. mean = 1000
standard deviation = 4358.9
b. expected value of average damage bar Y = 1000
probability bar y exceeds 2000 = 0.011
Step-by-step explanation:
we have p1 = 95%, y1 = 0, p2 = 5%, y2 = 20000
Mean = (0.95 * 0) + (0.05 * 20000)
= 1000
var(y) = E(y²) - E(Y)²
= we solve for E(y)²
= 0²*0.95 + 20000²*0.05
= 0 + 20000000
then the variance of y = 20000000 - 1000²
=20000000-1000000
= $19000000
standard deviation is the square root of variance
= √19000000
= 4358.9
2.
a. Expected value of average is also the mean = 1000
b. we are to find probability that barY exceeds 2000

= 1000/435.889
= 2.29
1-p(z≤2.29)
= 1 - 0.989
= 0.011
so the probability that barY exceeds 2000 is 0.011
Turkey dinner has to be zero as 0/? = 0 and it would be undefined if it was ?/0
Dinner plate would be 0 as ? * 0 * ? = 0
Radish is ?^2 cake as solving for radish will get that
Cake will be 4 as turkey is 0
Since cake is 4, radish is 16
Let’s plug them in to figure it out
0 / 4 = 0 ✅
16 * 0 * 4 = 0 ✅
4 = 16 / 4 ✅
4 / 4 = 0 + 1 ✅
0 + 16 * 4 = 64
Turkey = 0
Cake = 4
Radish = 16
Dinner plate = 0
? = 64
From the information given,
Students ticket = $4
Adult ticket = $6
Let student ticket be x, and adult ticket be y.
This means;
