Answer:
Step-by-step explanation:
100 + 100÷100 - 100 = 100 + 1 -100 {apply BODMAS}
= 101 - 100 = 1
Answer:
See explanation below
<u>Step-by-step explanation:</u>
range = 2200 - 300 = 1900
To find standard deviation, we have:
standard deviation = range/4 =
= 475
The range rule of thumb estimate for the standard deviation is 475
Given:
Standard deviation,
= 475
Margin of Error, ME = 100
= 1 - 0.90 = 0.10
Za/2 = Z0.05 = 1.64
Find sample size, n:
n ≥
n ≥
n ≥ 60.68
≈ 61
Minimun sample size,n = 61
Answer: $4
The cost of an 8x10 piece is $2, and 16x20 is just 2 times that amount, multiply the cost.
24 times 7 = 168 times 145 = 22, 680 hours
