Fill in the blanks in the photo below.

Step-by-step explanation:

The scatter plot is a plot of amount spent on entertainment(in dollars) against the number of hours worked. The equation of the line of best fit is given as

y = 0.6x + 21.82

This equation gives the predicted amount spent on entertainment while the table gives the exact amount spent on entertainment.

1) when the number of hours worked is 7.8,

The observed amount is $33.50

The predicted amount is y = 0.6 × 7.8 + 21.82 = $26.5

The residual is 33.5 - 26.5 = $7

2) when the number of hours worked is 10.2,

The observed amount is $21.5

Approximately 22

The predicted amount is y = 0.6 × 10.2 + 21.82 = $27.94

Approximately $28

The residual is 22 - 28 = $6

blue marble is 15 times out of 50 = 15/50 reduces to 3/10

landing on tails is 24 out of 50 = 24/50 reduces to 12/25

to find the probability of both multiply together:

3/10 x 12/25 = 3 x 12 / 10 x 25 = 36/250

if you multiplied the numerator and denominator by 10 you get 360/2500.

the answer is 360/2500
