I'm guessing you're looking for the mean or average? That would be the sum of all the ages divided by the numbers of people
So:
19+8+21+19=67
Divided by 4
67/4= 16.75
Rounded up you get 17

PLEASE HELP!!!!
3241004551 [841]

Answer: Correct

Step-by-step explanation:

The conclusion is valid. Since \overline{AB} \parallel \overline{DC} and \overline{AD} \parallel \overline{BC}, we know that ABCD is a parallelogram because it has two pairs of parallel sides. Also, since \overline{AB} \cong \overline{BC}, we know that ABCD is a parallelogram with a pair of consecutive congruent sides, making it a rhombus.

PLEASE HELP ME The length of the one of the legs of a right triangle is 8m and the hypotenuse is 12m. Which of the following cho
Bas_tet [7]

Answer:

The length of the other leg is 8.94 m.

Step-by-step explanation:

Given that,

Hypotenuse of a right triangle is 12 m

The length of the one of the legs of a right triangle is 8 m

We need to find the length of the other leg. It is based on the concept of Pythagoras theorem. Let the other leg is h. So, according to this theorem,

H^2=b^2+h^2

H = hypotenuse = 12 m

b = base = 8 m

h^2=H^2-b^2\\\\h^2=12^2-8^2\\\\h=\sqrt{80}\\\\h=8.94\ m

So, the length of the other leg is 8.94 m.
