Question

Can someone PLEASEEE help me with this for questions 3-5

Answer 1

Answer:

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 = $\sqrt{(0.2 +1)^{2}+ (-3 + 3.5)^{2}}$

dAB = $\sqrt{(1.2)^{2} + (0.5)^{2}}$

dAB = $\sqrt{1.44 + 0.25}$

dAB = $\sqrt{1.69}$

dAB = 1.3

dBC = $\sqrt{(0.2 - 5)^{2} + (-3 + 1)^{2}}$

dBC = $\sqrt{(-4.8)^{2}+ (-2)^{2}}$

dBC = $\sqrt{23.04 + 4}$

dBC = $\sqrt{27.04}$

dBC = 5.2

Ratio $\frac{AB}{BC} = \frac{1.3}{5.2}$

        $\frac{AB}{BC} = 4$
