Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Given
y + 6 = 
(x - 9) ← distribute the parenthesis
y + 6 = x - 3 ← subtract 6 from both sides
y = x - 9 ← in slope- intercept form
Answer:
y = - 
x - 4
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = - and c = - 4 , thus
y = - x - 4 ← equation of line
Answer: 15
Step-by-step explanation: 5n + 10=10n - 65
-10n -10n
------------------------------
-5n +10 = -65
-10 -10
----------------------------
-5n = -75
divide -5 on both sides and you should get positive 15
First you plug in the missing values
y=3 x=4 z=2
3÷2×4-2
than you solve
the answer is 4
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
