Answer:

Mean: 33.454545 Median: 34.5 Mode: 25

Step-by-step explanation:

By putting all of the numbers in numerical order, then adding them and dividing them by 11 (the number of numbers in the list), you get 33.45 repeating as the mean. With the organized list of numbers find the middle number, which is 35, and that is the median. The mode, the most common number in the sequence, is 37 and 25.

25+25+27+28+32+35+37+37+39+41+42=368

368/11=33.45454545

Answer: $\displaystyle\ \large \boldsymbol{ 2t^2+5t+2= {(2t+1) (t+2)}}$

Step-by-step explanation:

$\displaystyle\ \large \boldsymbol{} 2t^2+5t+2=0 \\\\2t^2+\underbrace{4t+t}_{5t}+2=0 \\\\ (2t^2+4t)+(t+2)=0 \\\\ 2t(\underline{t+2})+(\underline{t+2})=0 \\\\ \boxed{(2t+1) (t+2)=0 }$
