Answer:
90°?..........................
Answer:
399.9 seconds
Step-by-step explanation:
First, do 20 divided by 150 to get the unit rate of how many seconds it takes for one meter and get 0.1333.
Next, multiply 0.1333 by 3,000 so you can get how long it takes for her to bike 3,000 meters and get 399.9.
Answer:
A. 0.0625
B. 0.1089
C. 0.81
D. 0.0196
Step-by-step explanation:
The proportion of variance is shared by the two correlated variables is given as the r².
Therefore,
For A. r = 0.25
Proportion of variance is shared by the two correlated variables = 0.25²
= 0.0625
For B. r = 0.33
Proportion of variance is shared by the two correlated variables = 0.33²
= 0.1089
For C. r = 0.90
Proportion of variance is shared by the two correlated variables = 0.90²
= 0.81
For D. r = 0.14
Proportion of variance is shared by the two correlated variables = 0.14²
= 0.0196
Answer:
-4x/7
Step-by-step explanation:
4x + 7y = -35
7y = -4x - 35
y= -4x/7 - 35/7
y= -4x/7 - 5
-4/7 (the slope is the x equation)
