Answer:
The best predicted IQ score is 103.
Step-by-step explanation:
We are given the following regression equation:
![y=100.2+0.00297x](https://tex.z-dn.net/?f=y%3D100.2%2B0.00297x)
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.
![y=100.2+0.00297(998)\\y=103.16406\\y\approx 103](https://tex.z-dn.net/?f=y%3D100.2%2B0.00297%28998%29%5C%5Cy%3D103.16406%5C%5Cy%5Capprox%20103)
Thus, the best predicted IQ score is 103.
Here you go!! Those are the points and labeled for you
Answer:
4 1/3 miles = 13/3 miles
Step-by-step explanation:
One way to add these mixed numbers is to convert them to improper fractions with a common denominator.
(1 5/6) + (2 1/2) = 11/6 + 15/6
= (11 +15)/6 = 26/6 = 13/3 . . . . (a fraction)
= 4 1/3 . . . . (a mixed number)
