Students in a psychology class are identified as either introverts or extroverts using a personality quiz. They are then asked how many close friends they have. The results are summarized in the table. a) What is the probability that one of the students selected at random is an extrovert or has fewer than 5 close friends? _

b) What is the probability that one of the students selected at random is an extrovert given that they have 5 or more close friends? _

c) What is the probability that one of the students selected at random is an introvert? _

just do 5.2 + 2 ( 7.2) and 1/3 x 3 (.9) and youv'e got your equation. 0.9( 9/10) + 7.2 ^2 = 16.4 hope i could !

step-by-step explanation:

is there a picture

step-by-step explanation:

( - 4 , -7 )

all the lines must parallel  

step-by-step explanation:

coordinates of c = ( - 1 , 2 )

3 units left = ( -4 , 2 )

9 units down = ( - 4 , 11 )

the equation of the parallel line would be y = 2x + 9

step-by-step explanation:

to start we need to find the slope of the original line. we can do that by looking at the coefficient of x, which is 2

since the slope of the original line is 2 and parallel lines have the same slope, we know the new line will also have 2 slope. now we can use that along with the point given in point-slope form to get the find equation.

y - y1 = m(x - x1)

y - 5 = 2(x + 2)

y - 5 = 2x + 4

y = 2x + 9
