You simplify the equation and then graph it duh, jk i have no clue i just need points
Answer:
y = 4.69X + 52.93 ;
As Education increases by 1 unit, an individual’s annual salary is predicted to increase by $4,690. ;
$86000

The regression equation obtained using a linear regression calculator :
y = 4.689X + 52.93182
Where ;
y = Salary ; x = Educational attainment
Slope is the Coefficient of x = 4.689
Intercept = 52.93
The slope value in thousand = 4.689 * 1000 = 4689 = 4690 (the slope is interpreted to the mean the change in y value per unit change in the value of x)
Therefore, salary increases by about $4690 for every unit increase.
If x = 7
y = 4.689(7) + 52.93182
y = 32.823 + 52.93182
y = 85.7548
Salary =, $86,000
To find out how much they earned, we need to find the GCF of 184 and 207.
The greatest common factor (GCF) of 184 and 207 is 23.
That means they earn 23 dollars per day. That is your answer for part b.
And Thomas worked 184/23 = 8 days
While Sharlina worked 207/23 = 9 days
That is your answer for part a.
Answer:
20%
Step-by-step explanation:
Well if there's 5 answers for the question, and he answered two questions. That means the two questions together have 10 answers.
He chose one answer for each question, that is 2/10 or 1/5 or 20%
