Answer: It is usefull.
Step-by-step explanation:
The regression squared talks to us about how well the model fits in the experimental data, where 0.0 means that the model does not fit at all, and 100% means that the model fits perfectly.
This is always true? well, really not, there are cases where you can have a regression square of 0.98, which would imply that the model is correct, but when you see the residual vs fit the plot, you may see some pattern, which implies that there is a problem with the model (you always expect to see randomness when you look at this graph). While for a prediction, this actually may work (at least in the range of the data points, outside this range the model and the data may not coincide at all)
Now, it still is useful in a certain range, so we can actually conclude that if R^2 = 0.949 represents a model that is useful for predicting the exam marks.
Answer: 9/25
Step-by-step explanation: .36 equals 36/100 in decimal form.
Reducing it into its simplest form:
Both numbers are divisible by 4-
36/100 = 9/25 - which is the simplest form.

Answer:
Step-by-step explanation:
Let's solve for b.
−2(bx−5)=16
Step 1: Add -10 to both sides.
−2bx+10+−10=16+−10
−2bx=6
Step 2: Divide both sides by -2x.
−2bx/−2x=6/−2x
b=−3x
Answer:
b=−3x
———————————————————
Let's solve for x.
−2(bx−5)=16
Step 1: Add -10 to both sides.
−2bx+10+−10=16+−10
−2bx=6
Step 2: Divide both sides by -2b.
−2bx/−2b=6/−2b
x=−3b
Answer:
x=−3b
