The probability of picking a blue pen from a cup of pens is 1/3. Tim picks one pen from the cup without looking, records the color, and puts the pen back. he does this 15 times. how many times can he expect to pick a blue pen?

5

Step-by-step explanation:

1/3 of 15 is five because 5 plus 5 plus 5 is 15.

Step-by-step explanation:

1/3 of 15 is five because 5 plus 5 plus 5 is 15.

y = 3x+4

step-by-step explanation:

to find the slope

slope = (y2-y1)/ (x2-x1)

    = (-8-4)/ (-4-0)

    = -12/-4

  = 3

using the slope intercept form of a line

y= mx+b

we know the slope is 3

we know the y intercept is 4 ( the point where it crosses the y axis or x=0)

y = 3x+4
