Joe surveyed 128 students at his school. In the survey, he asked students what type of sibling they had: brother, sister, both, or neither. His data is in the Venn diagram below. (I need answers for 1, 2, and 3

answer: list the statements and i will follow up!

step-by-step explanation:

answer is  

c.

36

step-by-step explanation:

is the anwser b. (-13)?

d

step-by-step explanation:

the two points from this line are   (0,4)   & (2,-2)

we can call

now, lets find the slope (m):

now finding b (the y intercept). this is the point at the y-axis where the line cuts the axis. looking at the graph, it is y = 4. so the point is 4. hence b = 4

the slope-intercept form is given by  

putting the points, we have:

d is the correct answer.
