Answer:
15
Step-by-step explanation:
Andy to get to Willie's house = 15 ways
Andy to get to Willie's house = 45 ways
<h3>
How to determine the ways</h3>
From the information given, we have that from
Andy's house to Billy's hometown = 3 roads
Billy's hometown to Willies house = 5 ways
To travel from Andy's house to Willies house, we should multiply the number of ways
= 3 × 5
= 15 ways
Dan's ranch to Andy's house = 1 road
To Willie's house = 2 roads
For Andy to get to Willie's house, we have;
= 3 × 15
= 45 ways

Answer:
A = 192
Step-by-step explanation:
r = 16/2 = 8
A = 3x(8)^2
8^2 = 64
A = 3 x 64 = 192
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
