Answer:
Try 116?
Explanation:
First, let's us know the formula for finding area of a rectangle.
Formula - A = l * w
In the image, it shows the length (12) and width (10)
Length = L
Width = W
Now, what is 12 x 10? 120
Because we need the shaded region and the little box isn't apart of it, we need to find the area of that box to and subtract it from big box
The length is 2 and the width is 2, shown by the image.
2x2 = 4
120-4 = 116
Answer:
Step-by-step explanation:
Given that in our industry on average a firm paid out record year end bonuses of $125,500 per employee for 2008. We would like to take a sample of employees at our firm to see whether the mean year end bonus is different from the reported mean of $125,500 for the population.
1. Sample Mean =
118000
2. Population Mean = 125500
3. Population Standard Deviation = 30000
4. Sample size = 40
5. Alpha Error = 5%
6. Confidence Coefficient = 95%
7. Calculate Test Statistic = Mean difference /s td error = -1.581
8. Rejection Region Critical Value = If Z statistic is below -1.96 or above 1.96
Answer:
question 1: the lower left hand graph represents that equation.
question 2: a+b = 180°
question 3: a = b
question 4: a + b = 90°
question 5: a + b = 90°
Answer:
3 follows 4 from 5 backwards
Answer:
9' - 1.29"
Step-by-step explanation:
Total rise = 5' - 2"
Total run = 7' - 6"
1' = 12" = 1 feet = 12 inches
5' = 5 * 12 = 60"
3' = 7 * 12 = 84"
Total rise = 60" + 72" = 62"
Total run = 84" + 6" = 90"
Length of stringer = hypotenus
Hypotenus = √(total rise² + total run²)
Hypotenus = √(62² + 90²)
Hypotenus = 109.28860"
Convwrting back to feet and inches
= 9' - 1.29"
