Answer:
yards.
yards.
Step-by-step explanation:
We have been given that a square playground is surrounded by a sidewalk on all sides. The sidewalk is 
yards long on each side of the park.
Since side walk is 0.5 yard wide, so each side of playground will be 0.5 less than each side of sidewalk.
Since playground is square, so perimeter of playground will be 4 times the length of each side of playground.
Upon distributing 4 we will get,
Therefore, perimeter of playground will be yards or yards.
3x+7+5x-4=67
8x+3=67
8x=64
x=8, now sub 8 for x
3(8)+7
24+7=31
Answer:EF=31

Answer:
0.3277 = 32.77%
Step-by-step explanation:
If we want the probability for Sasha being late after the fifth day, we need that in the first five days she is not late, which has a probability of 1 - 0.2 = 0.8
So, multiplying the probability for each day, we have that:
P = 0.8 * 0.8 * 0.8 * 0.8 * 0.8 = 0.3277 = 32.77%
So we have a probability of 32.77% that Sasha's first delay will occur after the fifth day.
