Answer:
mean=average which means you add all of the numbers and divide by the number of numbers there are, which sounds pretty confusing, but i'll show you! 9+7+11+10+8=45, now you divide 45 by 5, which is how many numbers there are that we had to add. 45 divided by 5 is 9, which means the MEAN/average is 9!

hope this helps!
Area of frame=area of total-area of inside ting
area=lenght times width
so
inner one
length is 16-2-2 (both sides) or 12
width or height is 9-2-2=5
so area is 12 times 5=60
outter one
16 by 9
16 times 9=144
so
outer-inner=144-60=84
so 2nd option

Answer:
Step-by-step explanation:
- ED = FG = 4, easy to calculate
- ED ║ FG, both are vertical line segments
- EF ║ DG as the slopes are same
- m(EF) = (7-6)/(6-1) = 1/5
- m(DG) = (3-2)/(6-1) = 1/5
As we see the opposite sides are parallel and congruent. This is the property of a parallelogram
