Mode is E. 65 (Remember it's the number you see most.)
Range is D. 26 (Your difference between you highest and lowest number.)
Median is C. 72 (The number in the middle - 62 / 65/ 65 / 68 / (72) / 74/ 75 / 79 / 88)
Mean is C. 72 as well (Just add up all of your number, then divide by the amount that is there. *Solution 648/9 = 72)
You're welcome :)
Answer: 28
Step-by-step explanation:
times 4 and 7 seven and get your answer
We look for constants <em>a</em> and <em>b</em> such that

Rewrite all terms with a common denominator and set the numerators equal:

Then
<em>a</em> + 2<em>b</em> = 7
-2<em>a</em> - <em>b</em> = -8
Solve for <em>a</em> and <em>b</em>. Using elimination: multiply the first equation by 2 and add it to the second equation:
2 (<em>a</em> + 2<em>b</em>) + (-2<em>a</em> - <em>b</em>) = 2(7) + (-8)
2<em>a</em> + 4<em>b</em> - 2<em>a</em> - <em>b</em> = 14 - 8
3<em>b</em> = 6
<em>b</em> = 2
Then
<em>a</em> + 2(2) = 7 ==> <em>a</em> = 3
and so

Close. It's actually choice D) 7 < n < 17
The value n must be less than 5+12 = 17. If its equal to 17 or larger, then a triangle isn't possible.
Answer:
Rosa. 5a and 5b are not like terms. The letters have to be the same
