The statement of the question tells us that 45% of the customers getting an oil change will have their car tires rotated. Therefore:
probability of both = 0.7 x 0.45
= 0.315
= 31.5%

Answer:

64.3%

Step-by-step explanation:

You are finding a conditional probability. You divide the second percent by the first percent.

P(B | A) = [P(A and B)] / P(A)

P(A) = 0.7

P(A and B) = 0.45

= 0.45 / 0.7

= 0.643

= 64.3%

The equation $x=tan^{-1}(\frac{12}{5})$ can be used to find the measure of ∠BAC ⇒ 2nd answer

Step-by-step explanation:

Let us revise the trigonometry ratios in the right triangle ABC, where B is the right angle, AC is the hypotenuse, AB and BC are the legs of the triangle

The trigonometry ratios of the ∠BAC, the opposite side to this angle is BC and the adjacent side to it is AB are
