A club with college students is doing volunteer work this semester. Each student is volunteering at one of four locations. Here is a summary. Location Number of students Library Pet shelter Nursing home Tutoring center Three students from the club are selected at random, one at a time without replacement. What is the probability that the first student volunteers at the tutoring center and the other two do not

step-by-step explanation:

the first one is x^2+2x+2

the second one is x^2+4

the last one is x^2-4x+8

b

step-by-step explanation:

the equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (0, 4) and (x₂, y₂ ) = (3, - 5) ← 2 points on the line

m = = = - 3

with m = - 3 and (a, b) = (3, - 5), then

y - (- 5) = - 3(x - 3), that is

y + 5 = - 3(x - 3) → b
