Answer:
Step-by-step explanation:
Given
The x and y values
Required
The regression line equation
Because of the length of the given data, I will run the analysis using online tools, then analyze the result.
From the analysis, we have:
--- Sum of squares
--- Sum of products
The regression equation is calculated as:
Where:
So, we have:
So:
becomes
Answer:
(5, 8)
Step-by-step explanation:
(5. – 5) down 3 units => (5, -8)

Answer:
$98.4.
Step-by-step explanation:
Since the university has decided that for the following year lecture costs will increase by 20%, workshop costs by 10%, and examination costs will stay the same, and that for level 2 the current hourly costs are 10, 24, and 60 respectively To determine how much the level 2 course cost in the following year, the following calculation must be performed:
10 x 1.2 + 24 x 1.1 + 60 = X
12 + 26.4 + 60 = X
98.4 = X
Thus, the level 2 course will cost $ 98.4 next year.
Answer:
slope= 3/5 y int=-2 equation y = 3/5 -2
Step-by-step explanation:
slope= rise over run
y int = where the y axis and the line meet
equation= y =mx+b
m=slope
b = y int
