30(6)+25(4)+20(9)=460
$460 this week
Answer:
Down below
Step-by-step explanation:
Sub in the values
y = Mx + b
4. y = -3x + 7
5. y = 2/3x + 8
6. y = 4x - 3
7. Y = -1/5x - 1
8. -5/6x +0
9. Y= 7x -2
Answer:
So then the we have perfect linear association. Because the heights and weights of the men are similar.
Step-by-step explanation:
Let X represent the Height and Y the weigth
We have the follwoing dataset:
X: 70, 69
Y: 169, 164
n=2
The correlation coefficient is a "statistical measure that calculates the strength of the relationship between the relative movements of two variables". It's denoted by r and its always between -1 and 1.
And in order to calculate the correlation coefficient we can use this formula:
For our case we have this:
n=2
And if we replace in the formula we got:
So then the we have perfect linear association. Because the heights and weights of the men are similar.
Answer:
exactly 12:00 midnight on a 24hour clock is represented as 00:00
Y = -x/5 I believe.
The negative reflects over the y-axis
and the coefficient 1/5 stretches
