Andrew took a random sample of 10 decorated ceramic cups from a population of 100 cups to determine the sample mean number of defective cups. Barbara took another random sample of 10 cups from the same population for the same task. What would happen if Andrew and Barbara both choose a sample size of 20?

i am sure it will be 90 degrees.

step-by-step explanation:

x-3y=4

step-by-step e

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.
