Answer:
8 hours
Step-by-step explanation:
Job v starts at time 0 and completes at time 3.
Job w starts at time 1 and completes at time 4.
Job x starts at time 4 and completes at time 8.
Job y starts at time 8 and completes at time 10.
Job z starts at time 10 and completes at time 15.
The average completion time is (3 +4 +8 +10 +15)/5 = 8 . . . hours.
_____
<em>Comment on the schedule</em>
Jobs v and x are the only ones completed by the time due. The latest is 8 hours late. If they are scheduled in order of due time, jobs v, w, and y can be completed by the due time; the others will be 4 and 6 hours late.
Angle 4 equals 34 degrees since angle 2 and 4 are opposite angles and opposite angles are congruent

Answer:
5901
Step-by-step explanation:
The margin of error is the critical value times the standard error.
ME = CV × SE
For α = 0.05, the critical value is z = 1.96.
The standard error of a proportion is √(pq/n). Given p = 0.04, then q = 1−p = 0.96.
The margin of error is 0.5% or 0.005.
Plugging in:
0.005 = 1.96 √(0.04 × 0.96 / n)
n ≈ 5901
CP - the cost of painting the house for Painting USA company [$]
cP = 75 + 25 * 25 = 75 + 625 = 700 [$]
cU - the cost of painting the house for Upscale Home Painting company [$]
cU = 0 + 40 * 25 = 1000 [$]
cP < cU
The most cost effective is Painting USA company.
n - number of houres required to paint the house if the same cost for both companies
75 + 25 * n = 40 * n
40 n - 25n = 75
15n = 75 /:15
n = 5
The cost of paining the house is the same for both companies if the number of houres required to paint the house is 5.
