Answer:
Step-by-step explanation:
since both the figures are similar, the ratio of the corresponding sides will be constant. We will see the ratio of the corresponding sides

Step-by-step explanation:
we have
To convert to vertex form complete the square
Rewrite as perfect squares
----> equation in vertex form
The vertex is the point (-3,-20) (is a minimum)
Yes. 5 meters = 500 centimeters.
Answer is 34.96$ for the final cost.
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
