Can someone me with this for questions 3-5

The answer to your question is below

Step-by-step explanation:

3.-

P(A) = 0.3

P(A and B) = 0.24

P(B) = ?

P(B) = P(A) - P(A and B)

P(B) = 0.3 - 0.24

P(B) = 0.06

4.- From the graph we know that

C (1, 1)

radius = 4

Equation of a circle

                                 (x - h)² + (y - k)² = r²

Substitution

                                 (x - 1)² + (y - 1)² = 4²

Simplification

                                 (x - 1)² + (y - 1)² = 16

5.-

Points

A (-1 , -3.5)     C (5, -1)      B (0.2, -3)

dAB =

dAB =

dAB =

dAB =

dAB = 1.3

dBC =

dBC =

dBC =

dBC =

dBC = 5.2

Ratio

x+y = 29, 5x + 2y = 100

step-by-step explanation:

i'm guessing it was a multiple first option was the correct answer
