Answer:
0.29
Step-by-step explanation:
z-score is given by the formula:
z=(μ-M)/σ where
- μ is the hypothesis drive distance, which is 222
- M is the mean sample drive distance
- σ is the standard deviation of the sample drive distance
Therefore
z=(222-218)/14≈0.29
B.$2.55 i think but just check
Answer:
Height, 24, 80, and cubic feet
Step-by-step explanation:
I just did this on edge-unity and it gave me that.
Length = 31 ft
width = 19 ft
Assume that the width of the rectangle is w.
We are given that the length is 12 ft more than the width. This means that the length of the rectangle is w + 12
The perimeter of the rectangle in this case would be:
perimeter = 2 (length + width)
perimeter = 2 (12 + w + w)
perimeter = 24 + 4w
Assume that Dan would use all 100 ft of fencing to surround the yard. This would mean that the largest perimeter is 100 ft.
Therefore:
perimeter = 24 + 4w
100 = 24 + 4w
4w = 100 - 24
4w = 76
w = 19 ft
Since we have calculated that the width of the yard is 19 ft, we can substitute to get the length as follows:
length = 12 + w
length = 12 + 19
length = 31 ft
Answer:
Step-by-step explanation:
Selling price = (100+5)/100 × 1400
= 105 × 14
= $ 1470.00
