Answer: The probability that you select a women who passes is 1/2.

First, let's look at the men. 21 of the 84 test takers were men. If the ratio is 5:2 for failing. Then, 15 failed and 6 passes.

Second, let's look at the women. 63 of the test takers were women. If double the number passed, then 42 passed and 21 failed.

The chances that a random person was a women who passes is 42 out of 84 or 1/2.

Can someone help me?
Ne4ueva [31]

Answer:

Step-by-step explanation:

All the interior angles are of measure 60 degrees.

We want to find the height of this triangle.  Call it h.  On the left side of this illustration is a right triangle with height h and base (1/2)(10), or 5.

The ratio of height to base is the tangent of 60 degrees:

                                    h

tan 60 degrees = --------------

                                     5

                                                  h

and tan 60 degrees = 1.73  = ------

                                                   5

Multiplying both sides of this equation by 5 yields h = 8.66.  This is |BD|.  This is the same as Answer B.

A function has a constant tripling time. What type of function does this represent?
Olenka [21]
This would be an exponential function.

Exponential functions are of the form 

y = a*bˣ, where a is the initial value, b is the rate the function changes by, and x is the time period.  Since this triples, b would be 3.
