Answer:
-6, 2
Step-by-step explanation:
using the zero product property, 0=(x+2)^2-16, so, 16=(x+2)^2, square root both sides, then 4= +or- x+2
so x is equal to -6 and 2
Answer:
4cm x 5cm x 3cm = 60cm
Step-by-step explanation:
You have to multiply each number by the next, then you have the area, to find the PERIMETER, you multiply each number by the amount of sides it is on and add
The answer is w=5 how I got it was u add 10 to both sides than minus seven to both sides than u divide and u get w=5
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
B. y=2/3x-13/3 is written in slope intersept form
