Answer:
y hat = 2114.20 + 18.96x
Step-by-step explanation:
Given the least square regression model equation:
y hat = -959.00 + 8.60x
weld diameter x ; shear strength y (in pounds)
1 lb = 0.4536 kg
To express shear strength y in kilogram:
y is multiplied by 0.4536
(y hat × 0.4536) = -959.00 + 8.60x
Divide both sides by 0.4536
(y hat × 0.4536) / 0.4536= (-959.00 + 8.60x) / 0.4536
y hat = 2114.1975 + 18.959435x
y hat = 2114.20 + 18.96x
Answer:
The second one
Step-by-step explanation:
Answer:
Step-by-step explanation:
Amount by which the plant gre in one month = 9.5 - 8.75 = 0.75
Amount by which it will grow in x months = x * 0.75
The hegiht of the plant after 6 months = amount it will grow by in 6 months + current heigt = 0.75x + 8.75
Hence answer is
d
Answer: You can watch 14 vines.
Step-by-step explanation: 1 2/5 is equal to 1 4/10
1 4/10 is equal to 14/10
So the amount of vines you could watch is 14 in 1 minute and 24 seconds.
3/5 is the answer. Difference means to subtract
