1.) The mode is the number that's most frequent in a given list. In our list, we have 2, 4, 4, 5, 5, 5, 6, 6, 6, 6, 7, 9, 10. Our most frequent number is 6; therefore, our mode is 6.
2.) The median is the number in the middle of a list organized from least to greatest. 2, 4, 4, 5, 5, 5, 6, 6, 6, 6, 7, 9, 10; 4, 4, 5, 5, 5, 6, 6, 6, 6, 7, 9; 4, 5, 5, 5, 6, 6, 6, 6, 7; 5, 5, 5, 6, 6, 6, 6; 5, 5, 6, 6, 6; 5, 6, 6; 6. 6 is our median.
I hope this helps, despite your answer choices not providing the correct answer.
A two-digit number is twice the sum of its digit. If the tens digit is 7 less than the unit digit, find the number. Let x= the unit digit Then y= the tens digit <span>And 10y+x= the number
</span>x+y= the sum of the digits <span>Now we are told that 10y+x=2(x+y) ------1st equation </span> <span>We are also told that y=x-7 ----------- 2nd Equation </span> <span>So our equations to solve are: </span> (1) 10y+x=2(x+y) <span>(2) y=x-7 </span>
Factoring is a useful skill in real life. Common applications include: dividing something into equal pieces, exchanging money, comparing prices, understanding time, and making calculations during travel.
Sorry if this is a little wordy, I can get carried away with this sort of thing
anyway, hope this helped and answered your question :)
