Answer:
1st blank: 1
2nd blank: -3
Step-by-step explanation:
1 - 2 / 4 - 5
-1/-1
slope = 1
1 = 4 + b
-3 = b
2 = 5 + b
-3 = b
hope this helps :)
To get the slope of -2y+38x=38.
Let us convert to slope intercept form, that is y=mx+b
So, subtracting 38x from both sides, we get
-2y=-38x+38
Now, Divide by -2 on both sides, we get
y=(-38/-2)x+(38/-2)
y=19x-19
Slope, m=19
Answer:
9 + 4x = 101
Step-by-step explanation:
9 + 4x = 101 Equation
( +9 - 9 ) + 4x = ( 101 - 9 ) Subract 9 on both sides
4x = 92 Simplify
x = 23 Divide 4 on both sides

I think it's 1/6. Because before school she drinks 1/4 then before lunch she drink 2/3 if 1/4 so you would multiply. 1*2=2. 4*3=12. So you get 2/12 or if you simplify, 1/6
Answer:
Step-by-step explanation:
Given that for a biology project, you measure the weight in grams and the tail length in millimeters of a group of mice.
The correlation is r = 0.9
If you had measured tail length in centimeters instead of millimeters, what would be the correlation?
For this we must understand the meaning of correlation and formula
Correlation is a measure of linear association between the two variables and always lie between -1 and 1
This is got by dividing covariance of (x,y) by product of std deviation of x and y
So because we changed the units of length correlation coefficient would not change.
It would remain the same as 0.90
