Of 60 cities, 3 have a lake and 29 have a river running through them. What fraction of these 60 cities have a lake or river runn

nekit [7.7K]

Hello!

We know our denominator is 60, because that is the total amount of cities. Now, we must find our numerator:

3 + 29 = 32

Fraction: 32/60

You can simplify this by dividing both the numerator and denominator by 4:

32 ÷ 4 = 8 60 ÷ 4 = 15

FRACTION (SIMPLIFIED): 8/15

A line of best fit predicts that when x equals 30, y will equal 34.215, but y actually equals 32. What is the residual in this c

Katarina [22]

Answer: A. - 2.215

Step-by-step explanation:

• A residual is the difference between the actual value and the predicted value in a regression model. It represents the vertical distance from the actual point to the point on the regression line.

$\text{Residual=Actual value of y -predicted value of y}\\\\\Rightarrow\text{Residual}=32-34.215\\\\\Rightarrow\text{Residual}=-2.215$

Hence, the residual in this case = -2.215
