Please help! A graph titled ticket sales has rainy days in season on the x-axis and total ticket sales (dollars) on the y-axis. Points are grouped together and decrease. Points are at (1, 2,800), (2, 2,500), (2, 3,500), (3, 1,400), (4, 3,000), (5, 2,800), (6, 1,500), (6, 2,500), and (8, 1,000). Use the points to describe the data and determine the line of best fit. What type of correlation do the data points represent? What is the equation that best represents the data?

the diameter is 16 cm. are you a teacher?

step-by-step explanation:

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.
