Answer:
The best predicted IQ score is 103.
Step-by-step explanation:
We are given the following regression equation:
where y is the predicted IQ score and x is the brain volume.
y is the dependent variable and x is the independent variable.
Significance level = 0.05
We have to find the best predicted IQ score with a brain volume of 998 cubic cm.
We put x = 998 in the equation.
Thus, the best predicted IQ score is 103.
I think the answer is 126.6466666666667but rounded be 126.65
Answer: The approximate solution is (-0.36, 2.08).
Given system of equations : x+5y=10 and 3x+y=1
Answer:
60 miles per hour
Step-by-step explanation:
You divide 300 by 5 and you get 60. You always need to divide the upper part to the lower part to reach the distance in ONE UNIT OF TIME. There, you have 5 seconds, yet you need the distance in 1 second.
This all is assuming that the train moved at a constant speed, where
ACCELERATION = 0, which is pretty improbable for a train.
