Answer:

probability is 1/2

Step-by-step explanation:

multiples of 3 that will occur in standard dice = 3,6

hence, theres 3 occasions that u will roll a 4 or multiple of 3 on a standard # cube:

3/6 = 1/2

Use complete sentences to describe why it is valid to say that both a function and its inverse describe the same relationship.

Serhud [2]

Answer:

Step-by-step explanation:

A comparison between a function and its inverse would show that the domain and range of the original function swap. The domain of the function becomes the range of the inverse, the range of the function becomes the domain of its inverse.

Looking at ordered pairs of the function and its inverse would look like this:

(2,4) on the original function becomes (4,2) on the inverse.

While the graph of a function and its inverse are noticeably different an important thing to note is that it is merely a reflection across the line y=x.

So even though they appear different you are looking at the same relationship just as y vs. x instead of x vs. y

I hope this helped you because i barley understood this myself.

Percents from Tabled Values

alexandr1967 [171]

Answer:

17.9% of men have a HS degree
50.5% of 2-yr degree earners were women
27.9% of the group has a 4-yr degree or higher

Step-by-step explanation:

It is convenient to use a spreadsheet to total the numbers for you. This reduces errors and put the numbers in a form that makes it easy to see what you're working with in any given calculation.

men with HS degree = (male HS)/(all male)

= 76/425 ≈ 0.1788 ≈ 17.9%

2-yr degrees that are women = (female 2-yr)/(2-yr total)

= 248/491 ≈ 0.5051 ≈ 50.5%

4-yr degrees in group = (4-yr degrees)/(total group)

= 258/925 ≈ 0.2789 ≈ 27.9%

<em>Comment on the problem</em>

The spreadsheet is identical to the one used for your other problem. All that needed to be done was to enter the new numbers. The formatting, headers, and formulas remained the same. For solving these problems, it's a matter of picking the two numbers needed from the appropriate row or column and computing their ratio.

(The computations were done by hand here to better show you the numbers used and the rounding to tenth percent. They can be done in the spreadsheet with point and click.)
