(see below)

Step-by-step explanation:

given that the playground is in the shape of a rectangle where

Length = 400 ft and Width = 200 ft

Perimeter = Length + Length + Width + Width

= 400 + 400 + 200 + 200

= 1200 feet long

We also know that 1 ft = (1/3) yard

hence 1200 feet = 1200 x (1/3) = 400 yards

We are given that fencing cost $20 for each yard.

Hence for 400 yards, the total fencing cost will be

= $20 per yard x 400 yards

= 20 x 400

= $8000

8000 dollars for 400 yds

Step-by-step explanation:

We need to find the perimeter

P = 2(l+w) where l is the length and w is the width

P =2( 400+200)

P = 2(600)

P = 1200 ft

Change from feet to yards

3 ft = 1 yd

P = 1200 ft * 1 yd / 3ft = 400 yd

Now each yd is 20 dollars so multiply by 20

400 * 20 = 8000 dollars

Answer from: Quest

median is the value separating the higher half of a data sample, a population or probablity distribution from the lower half.

step-by-step explanation:

say you have 3,8,7,3,1,9,8 order them from lowest to highest

if orderd it would be 1,3,3,7,8,8,9 now you take away from the lowest and the highest until you end up in the middle.

so you would remove the 1 and 9 leaving you with 5 digits remaining

when you've reached the middle that would be your answer so in this case the answer is 7

if there were two numbers left say 7 and 5 you'd and them together so 12 then divide by 2 witch would equal 6 so the answer would be 6

good luck on that project hoped i you at all

hello,

b) 62.47% of the students are between 14 and 18 years old.

step-by-step explanation:

mean = 15 and standard deviation = 2

student between 14 to 18

formula used z-score

for age 14 , z score

using z-table , p(z> -0.5)=0.3085

for age 18 , z score

using z-table , p(z< 1.5)=0.9332

p(-0.5< z< 1.5)=0.9332-0.3085 = 0.6247

thus, 62.47% of the students are between 14 and 18 years old.
