Which linear equation best represents the line of best fit for the scatterplot?

Mathematics

Lena [83]1 year ago
7 0

Answer:

y = -\frac{1}{3}x

Step-by-step explanation:

The scatter plot trends downward from left-> right, meaning that it is negative. Next, use two points to solve for the value for the slope.

In this case, I will use (-3 , 1) & (0 , 0)

Use the following equation. m = slope:

m = \frac{y_2 - y_1}{x_2 - x_1}

Let:

(x_1 , y_1) = (0 , 0)\\(x_2 , y_2) = (-3 , 1)

Plug in the corresponding numbers to the corresponding variables:

m = \frac{1 - 0}{-3 - 0} = \frac{1}{-3} = -\frac{1}{3}

Your answer will be:

y = -\frac{1}{3}x

The average number of newspapers for sale in an airport stand is 15. SD is 6. The average age of the pilots is 36 and SD is 4. W
balu736 [363]

Answer:

The average age of pilots has a lower coefficient of variation, so it is the most consistent data set.

Step-by-step explanation:

The coefficient of variation is used to measure consistency of a data set. It is the standard deviation divided by the mean. The higher the coefficient of variation, the more variable, that is, the least consistent the data set is.

The average number of newspapers for sale in an airport stand is 15. SD is 6.

The consistency is:

C = \frac{6}{15} = 0.4

The average age of the pilots is 36 and SD is 4.

The consistency is:

C = \frac{4}{36} = 0.11

The average age of pilots has a lower coefficient of variation, so it is the most consistent data set.
