Answer:
ans = $105 per hour
Step-by-step explanation:
first: you subtract the charge for parts from the total and this gives you $446.25.
second: because the technician worked for 4.25 hours = $446.25,if the technician worked for an hour what would be the cost?
4.25hr = $446.25
1 hr = x . then cross multiply.
4.25x = 446.25 then divide by 4.25 both sides to find th value of x, which is the cost of labour per hour
The answer is 400 degrees because 325 + 75 = 400 degrees
Answer:
np = 81 , nQ = 99
Step-by-step explanation:
Given:
X - B ( n = 180 , P = 0.45 )
Find:
Sampling distribution has an approximate normal distribution
Computation:
nP & nQ ≥ 5
np = n × p
np = 180 × 0.45
np = 81
nQ = n × (1-p)
nQ = 180 × ( 1 - 0.45 )
nQ = 99

Just took the test.
Answer:
188.53 m²
Step-by-step explanation:
Total area of the stage = area of the rectangle + area of the semicircle
Area of rectangle = Length * Width
Length = 16 m
Width = 5.5 m
Area of rectangle = 16*5.5 = 88 m²
Area of semicircle = ½(πr²)
r = ½(16) = 8 m
Area = ½(π*8²)
Area = 100.53 m²
Total area of the stage = 88 + 100.53 = 188.53 m²
