Then total bagels=x+3x=4x
A) The fraction of bagels are plain
B) The percent of bagels are plain
C) If ill bought 2 dozen bagels, the number of plain bagels
The number of sesame bagels

Answer:
3rd graph.
Step-by-step explanation:
Roots of the equation are where the graph crosses the x axis. So the bottom left (3rd) graph is correct.
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
