Question 1)
575 = 100%
57.5= 10%
57.5 × 2= 115 (20%)
question 2)
575=100%
57.5=10%
115=20%
5.75=1%.
5.75 × 4=22.8 (4%)
22.8 (4%) + 115 (20%) =137.8(24%) which would be rounded up to 138
hope this helps♡♡~~Chyna
E(X) = 0(0.7) + 1(0.2) + 2(0.1) = 0.2 + 0.2 = 0.4
The expected daily loss due to blackouts = 0.4 * $500 = $200
Var(X) = 0(0.7 - 0.4)^2 + 1(0.2 - 0.4)^2 + 2(0.1 - 0.4)^2 = 0.04 + 0.18 = 0.22
The expected daily variance due to blackouts = 0.22 * $500 = $110
Answer:
depends on situations
Step-by-step explanation:
Answer:
see below
Step-by-step explanation:
Add 4 to find the solution:
z ≤ 7
The value 7 is included in the solution set, so there will be a solid dot at that point. Numbers less than 7 are also included in the solution set, so the number line will be shaded to the left of that solid dot.
Answer:
C
Step-by-step explanation:
Mean is the average. To find mean, add all the numbers in a data set, then divide by the number of values.
Example: 1,2,3,4,5
Mean: 1+2+3+4+5= 15
Number of values: 5
15/5 = 3
Mean is 3
