Answer:
Coefficient of determination = 0.149769
Step-by-step explanation:
We are given the following in the question:
Coefficient of correlation, r = -0.387
We have to find the coefficient of determination.
Coefficient of determination =

Coefficient of determination:
- It tells us about the variation explained in the model.
- This correlation of determination tells that 14.98% of the variation is explained in the model that is we can say that the independent variable explains 14.98% changes or prediction in the dependent variable.
- It ranges from 0 to 1 and a correlation of determination of 1 means that the dependent variable is 100% predicted by the independent variable.
- Correlation of determination of 0 means that the dependent variable cannot be predicted by the independent variable.
Assuming it's a constant rate, there is a four hour difference from t=1 and t=5, so subtract the difference in depth (0.03 - 0.06) and divide that by four.
-0.03/4 = -0.0075
So your change in depth in feet per hour is -0.0075

Answer:
The fraction of the students that walk in in Marla's school is equal to 
Step-by-step explanation:
Let
x------> the total students in Marla's school
we know that
The number of students that not ride the bus is equal to

The number of students that walk to the school is equal to

therefore
The fraction of the students that walk in in Marla's school is equal to 
First you need to know that the internal angles of a triangle always equals 180°. Therefore:
15+45= 90°
Then since the angles should equal 180, you do:
180-90=90
So the missing angle equals 90°
Answer:
you will need to find the difference (subtract) between two of the y points then do the same for the x points and put to difference of y on top of x and there is you slope using a graph( or if eaven, will come put as a whole number
