Answer:
y = - 0.833 + 29.5
y = 17
Step-by-step explanation:
Drawing a best fit line through the data points:
The approximate regression model would have an intercept of about 29.5
The slope = Rise / Run = (y2 - y1) / (x2 - x1)
The slope = (5 - 25) / (27 - 3) = 20 / 24 = -0.8333
The regression equation is thus :
y = mx + c
m = slope ; c = intercept
y = - 0.833 + 29.5
B)
x = 15
y = - 0.833(15) + 29.5
y = -12.5 + 29.5
y = 17

Answer:
4 pounds of lime and 5 pounds of pears
Step-by-step explanation:
I + P = 9
0.5l + 1.5P = 9.5
I = 9 - P
0.5(9 - P) + 1.5P = 9.5
4.5-0.5P + 1.5P = 9.5
4.5 + P (1P) = 9.5
P = 9.5-4.5 = 5
I = 9 - 5 = 4
Answer: 4 pounds of lime and 5 pounds of pears
