The solutions to the inequality y > −3x + 2 are shaded on the graph. which point is a solution? (0, 2) (2, 0) (1, −2) (−2, 1)

(2,0) is a solution.

Step-by-step explanation:

The given inequality is y > -3x + 2 and we have find the point of solution of this inequality.

For ( 0,2 ) ⇒ y > (-3) (0) + 2 ⇒ y > 2

                 But y coordinate of the point is 2 so it is not the solution.

For ( 0,2 ) ⇒ Y > (-3) (2) + 2 ⇒ y > (-6) + 2

                                            ⇒ y > -4

and y coordinate is 0 which is greater than -4 so (2,0) is a solution of the inequality.

For ( 1,-2) ⇒ y > (-3) (1) + 2 ⇒ y > (-3) + 2

                                          ⇒ y > (-1)

While y coordinate is (-2) which is less than (-1) so this point is not a solution.

For (-2,1) ⇒ y > (-3) (-2) +2 ⇒ y > 6 + 2

                                           ⇒ y > 8

while y coordinate is 1 which is less than 8 so ( -2,1 ) is not solution.

(2,0) is a solution.

a) 0.1535

b) 0.4866

c) 0.8111

Step-by-step explanation:

The probability that the next call come within the next t minutes is:

According to this model,

a) the probability that a call in comes within 1/2 minutes is =0.1535

b) the probability that a call in comes within 2 minutes is   =0.4866

c) the probability that a call in comes within 5 minutes is   =0.8111
