Question

Angelique makes beaded jewelry. The graph below shows the number of beads used for varying cord lengths.

Jewelry
A graph has cord length (inches) on the x-axis and number of beads on the y-axis. A trend line has a regression equation of y = 2.52 x + 1.61.

Angelique has a cord that is 32 inches long. Based on the information above, which is the best estimate for the number of beads she can use?
12
68
82
132

Answer 1

The best estimate for the number of beads Angelique can use for a 32-inch cord is approximately 82 beads. Therefore, the answer is 82

Based on the given information, Angelique has a cord that is 32 inches long. To estimate the number of beads she can use, we can use the regression equation provided: y = 2.52x + 1.61.

To find the best estimate for the number of beads, substitute the cord length (x = 32) into the equation and solve for y:

y = 2.52(32) + 1.61

y = 80.64 + 1.61

y ≈ 82.25

Rounding to the nearest whole number, the best estimate for the number of beads Angelique can use is 82.

Therefore, the answer is 82.
