Answer:
a) 0.64
b) -1.13
Step-by-step explanation:
We are given the following information in the question:
Women:
Mean, μ = 64.2 inches
Standard Deviation, σ = 2.8 inches
We are given that the distribution of heights of women is a bell shaped distribution that is a normal distribution.
Men:
Mean, μ = 69.4 inches
Standard Deviation, σ = 3.0 inches
We are given that the distribution of heights of men is a bell shaped distribution that is a normal distribution.
Formula:
5.5 feet = 66 inches
a) z‑score for a woman 5.5 feet tall
b) z‑score for a man 5.5 feet tall
Find the area of the rectangle that makes the master bedroom , bath and closet:
16 x 17 = 272 sq.ft
Subtract the area of the bathroom and hallway:
Bathroom= 10 x 5 = 50 sq. Ft.
Hallway: 7 x 4 = 28 sq.ft.
= 50 + 28 = 78 sq ft.
Area of bedroom and closet = 272 - 78 = 194 sq. Ft.
Now multiply area by price of carpet:
194 x 1.34 = $259.96
To find what the y value is, we just have to input the x value and solve.
y =
x + 2
y =
* 2 + 2
y =
+ 2
y = 3.2
That means that the missing half of the coordinate is
3.2.
Out of 3 coins, if you are given that 1 is on tails, then the most heads you could have is 3 coins - 1 tails = 2 heads.
The probability of getting 3 heads would be 0.
Area = Length x Width
Substituting the given values:
16S^2 t = 8St^2 x Width
Manipulating for Width:
Width = 16S^2 t / <span>8St^2
Rewriting the squared terms in simplified form :
</span>Width = 16 x S x S x t / <span>8 x S x t x t
</span>Cancelling the like terms
Width = 16 x S / <span>8 x t
</span>Cancelling the numeric terms :
Width = 2S / <span>t</span>
