Step-by-step explanation:
Use ToA method (tan = opposite / adjacent)
For this question we have to use pythagoras' Theorem to find the adjacent side.
take a as the length of the adjacent side.
given b = 12
c = 13
By pythagoras' Theorem,
Now we can find tan(x)
tan(x) = Opposite / adjacent
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.
