Answer:
x = 7
Step-by-step explanation:
<ACF = 90° (since AB is the diameter and it is perpendicular to EF)
But <ACF = 2(7x-4)
So
2(7x-4) = 90
14x-8 = 90
14x = 90+8
14x = 98
Dividing both sides by 14
x = 7

It means the scatter plot is a line with negative slope. The relation is perfectly described by a linear equation.
Toby should choose Project B because since there are equal number of the four colors of beads, you simply divide the total number of beads by four to get the number of one color of bead(re. green). 1020/4 = 255. Since Toby wants to use the project that uses an amount of beads under 260, Project B is the right choice.
