on a large college campus, 84% of the students report drinking alcohol within the past month, 33% report using some type of toba

Natasha_Volkova [10]

Answer: 0.31

Step-by-step explanation:

Let A denotes the event that the students report drinking alcohol and B denotes the students report using some type of tobacco product .

Given : P(A) =0.84 ; P(B)=0.33 and P(A∪B)=0.86

We know that $P(A\cap B)=P(A)+P(B)-P(A\cup B)$

Then, the probability that the student both drunk alcohol and used tobacco in the past month is given by :-

$P(A\cap B)=0.84+0.33-0.86=0.31$

Hence, the probability that the student both drunk alcohol and used tobacco in the past month = 0.31

First you have to subtract 1.3 from 0.75 which equals -0.55. Then you have to add 3/7 to 2 which equals 2 and 3/7. Then you divide 2 and 3/7 by -0.55 which equals 0.9785 and that’s your answer. Sorry I don’t know the answer for the second problem but I hope this helped.

Can someone solve this

dimaraw [331]

Answer:

y= -1/4x + (-1)

Step-by-step explanation:

(4,-2) (0,-1)

m= y2-y1/x2-x1

m=-2-(-1)/4-0

m= -1/4

y= mx + b

-2= -1/4(4)+ b

-2= -1 +b

+1 +1

-1= b
