Answer: 5/7
Step-by-step explanation:
I assume it is 100 meters, not 100100 meters.
Length (L)=width(w)+4
Perimeter: 2L+2W>100
Plug L=W+4 into the equation 2L+2W>100:
2(W+4)+2W>100
2W+8+2W>100
4W+8>100
4W>92
W>23
the width needs to be at least 23 meters

Multiple Answers
Step-by-step explanation:
We know that the mean is 35 and the median is 31.2 hours.
- Step 2: If we clear n of the percentil formule of the 6th percentile:
(n)()= 24 families → n=400 families.
- Step 3: true. The half of the population is 200. Therefore the 50% of the sample(the 50th percentile) is under or equal 31.2
- Step 4: By definition the median is the 50th percentil. So the 50 percentil → 31.2.
- Step 1: If we considerate that the 50th percentil is 31.2, a bigger percentil had to be bigger too.
- Step 5: False. At the beggining we have that the 6% of the population were below or equal to 20 hours, therefore the 25% of the data have to be greater or equal to 20.
