Answer:
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
Answer:
2+6x+11+3x27x+y
=x2+6x+11+3x28+y
Answer:
=3x28+x2+6x+y+11

yes
Step-by-step explanation:
493,712 divided by 8 = 61724
Answer:
The answer is attached as an image.
Step-by-step explanation:
- If we assume that the space is 100% of the population then:
88% have something and 12% have nothing.
So within the 88% there are 10% who have TV, 20% who have Radio and 58% who have both TV and Radio.
