Answer:
y = 3/5 + 4
Step-by-step explanation:
Given Coordiantes:
(0,4) - Y-intercept
(5,7) - Coordinates
To make an equation, first find the slope.




In decimals:

Now convert to point slope.


In decimals:

Now convert to slope-intercept form.
Find the Equation of the Line:

by solving for y using the Point Slope Equation.
y = 3/5 + 4
Answer:
The standard deviation of the sample mean is 4 minutes
Step-by-step explanation:
The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean
and standard deviation
, the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean
and standard deviation
.
For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.
In this problem, we have that:
The standard deviation of the population is 32.
Sample of 64.
So

The standard deviation of the sample mean is 4 minutes
Answer:
=288
Step-by-step explanation:
(4yz)-3(x)
(4(4)(2))-3(-3)
(4x8)x9
32x9
288
20 and 2/3 is correct, I think
Answer:
She should ski on Slope B because it is steeper
Step-by-step explanation:
Slope A
We need to find the "slope"
15/24 = 5/8
Slope B
12/16 = 3/4
To compare, we need a common denominator
5/8 3/4*2/2
5/8 6/8
<
Slope B is steeper because the slope is greater
She should ski on Slope B because it is steeper
