Answer:

0.25

Step-by-step explanation:

This is the question on conditional probability

Let A - the quadrilateral has four right angles

B - the quadrilateral has four equal side lengths

Required probability = P(B/A)

By definition of continuous probability

P(B/A) = \frac{P(AB)}{P(A)}

P(AB) = \frac{2}{20} =0.10

P(A) = \frac{8}{20} =0.4

Hence given probability = \frac{0.1}{0.4} =0.25

Need help with number 43 and 45 and need to show the work
Alex787 [66]
43:
       Negative temperatures are basically the same as normal ones, although they go below zero, so they are still the same distance apart from zero, just on the left side of the number line.

      To find the answer find the difference between 30.5°C and 0 (which is 30.5).

      Next, find the difference between -122.2°C and zero (122.2)

       Finally, add 122.2 + 30.5 to find the total distances from the zero combined for the full distances apart from each other.

     (We add them because -122.2 to the left of zero, and 30.5 is on the right)

      You should get 152.7 as your answer.

45:
     I'm guessing since it is asking for the deepest point (-5315) from sea level (0), the answer is -5,315 feet

     *Remember 5,315 is negative because numbers below sea level are all negative*

     So the answer should be -5,315 feet deep. (I'm not sure how to show your work for that I'm guessing it is 0 - 5,315 at the slightest).

 *Hope this all helped :)*

Suppose you are paid an annual salary, plus a bonus of 20% on annual sales over $500,000. Consider the two functions f(x) = x −
melisa1 [442]

Answer:

C. g\,\circ \, f (x) =g(f(x))

Step-by-step explanation:

Let be f(x) = x-500000 the excedent on annual sales and g(x) = 0.2\cdot x the bonus factor, to determine the bonus amount a composition of f(x) is g(x) must be done. That is:

g\,\circ \, f (x) =g(f(x))

Hence, the right answer is C.
