At a certain college, 100 students were surveyed. The results are in the two-way table above.

One of these 100 students is selected at random to give more detailed answers to some follow-up questions.

What is the probability that the chosen student has taken a public speaking class or is majoring in business administration?
Find the value of P(taken a public speaking class | majoring in business administration).

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c

im with everythinglos so yeahhhhh

step-by-step explanation:

if y=4x then you will substitute 4x in for y in the second equation.

8x + 4x = 18 combine like terms

12x = 18 divide by 12 on both sides

x = 18/12 or 3/2

now replace x in the first equation with 3/2 to get

y = 4 3/2

y = 6

the answer is a

(3/2,6)

hope that .
