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
Factors are numbers that when you multiply them you get another number or quantity
ex: 3 x 4 = 12
three and four are the factors because when multiplied they give you twelve, a new quantity.
Answer:
125 cm^3
Step-by-step explanation:
Find THE volume of this cube of side length 5 cm:
Volume of a cube is V = s^3, where s is the side length.
Here, V = (5 cm)^3 = 125 cm^3
Answer:
B
Step-by-step explanation:
Because there are 2 different y values for the x value of 5. All x values can only have 1 y value.
For B, there are y points on the x value of 5, so this fails the vertical line test, and is therefore not a function
Answer:
x=131/21
y=-23/21
Step-by-step explanation:
<u>Given:</u>
5x+2y=29
8x-y=51
<u>Eliminate y variable and solve for x:</u>
5x+2y=29
+ 16x-2y=102
_________
21x=131
x=131/21
<u>Plug x into either original equation and solve for y:</u>
5x+2y=29
5(131/21)+2y=29
655/21+2y=29
655/21+2y=609/21
2y=-46/21
y=-46/42
y=-23/21
