Since it's asking for for the range of variable B, look the y-coordinates.
The range is largest number subtracted by the smallest number.
8-1=7
Your answer should be 7.
Answer: B
Step-by-step explanation:
You can see that the length of the sides from abc are factored by 1/3 to get the length of xyz. Therefore, the scale factor is 1/3.
Answer:
first option
Step-by-step explanation:
Regression line is given in the form of: y = a + bx
Where b is the gradient
Working out 'b'
Σxy - [ΣxΣy]/N
Σx² - [Σx]²/N
Working out 'a'
a = [∑y/N] - b[∑x/N]
a = [2650/460] - 0.264[3920/460]
a = 5.86 - 2.25
a = 3.61
Regression line equation is
y = 3.61 + 0.264x
