Answer:

Total distance covered = 436 yards

Step-by-step explanation:

Walking path BE joins the midpoints B and E of the sides AC and AD.

By midsegment theorem,

"Line joining midpoints of two sides of a triangle is parallel and measure half of the third side"

m(BE) = \frac{1}{2}[m(CD)]

CD = 2(BE)

CD = 2(74) = 128 yd

From starting point D,

DE = 107 yd

EB = 74 yd

BC = \frac{254}{2}

     = 127 yd

CD = 128 yd

Total walking distance = DE + EB + BC + CD

                                      = 107 + 74 + 127 + 128

                                      = 436 yd

Total distance covered = 436 yards

ANYBODY WHO ANSWERS THIS WILL GET 60 POINTS. Male and female high school students reported how many hours they worked each week
Alexxandr [17]
D. The males have a suspected significant high outlier. 

The outlier will make the box plot be uneven and this will affect the spread and the center.

I know isn't A, because if anything that would make it more balanced.
I know it isn't B because this would not affect the spread or the center.
I know it isn't C because the question is not asking you to determine the spread and center, just to see if there is anything that would affect them.

I hope this helps!

If 3/4 gallon of paint covers 1/3 of the wall then how much paint is needed for entire wall
torisob [31]
3/4 times 3
3 times 3 =9 
9/4
9 divided by 4 = 2.25
because you have to paint the whole wall you have to have 2.25 so you can't round down therefore you have to round up
so the answer would be 
3 gallons
