15. 1/2 base * <span>hight ,</span> 1/2 * 11 * 6 = the answer is 33 cm^2
16. The "median" is the "middle" value in the list of numbers. To find the median, your numbers have to be listed in numerical order from smallest to largest, so you may have to rewrite your list before you can find the median. So the answer is 155.
17. <span>The mean is the usual average, so I'll add and then divide. (33+25+42+25+31+37+46+29+38) / 9 = 34

Answer: choice a
Step-by-step explanation:
Set up your variables. For this question lets use x, y, and z.
the equations will be . .
x + y + z = 165
x = 2y - 65
z = y -10
If we now substitude the equations for x and z with the first equation we cans solve for y. Hence the equation will be . . .
2y - 65 + y + y -10 = 165
y = 60
then substitude the equations for x and z with y.
your answer should match choice a.
100,000
0 is in the ten thousands place, 2 in the thousands. If the number to the right of the placeholder of the number you're rounding is five or more, you round up. Otherwise, you round down.
