Answer:
D) Survey 100 randomly selected students from the school
Step-by-step explanation:
This gives an equal chance to everybody, so it's not biased and it is of everybody that goes to his school. A is only the people on the football team so its not students in his school. Walking to school has nothing to do with the survey topic and so thats also definitely not it. C again doesn't give a fair chance to everybody, so it would be possible to get an accurate, unbiased answer. D is definitely your answer!
I hope that helps!!
Have an awesome day! :)
Answer:
Part A) The area of the figure is
Part B) The perimeter of the figure is
Step-by-step explanation:
step 1
Find the area of the figure
we know that
The area of the figure is equal to the area of triangle ABD plus the area of triangle BCD
The area of triangle is equal to
<u>Area of triangle ABD</u>
Observing the graph
substitute
<u>Area of triangle BCD</u>
Observing the graph
substitute
The area of the figure is
step 2
Find the perimeter of the figure
we know that
The perimeter of the figure is equal to
we have
the formula to calculate the distance between two points is equal to
Find the distance AB
Find the distance BC
Find the distance CD
Find the distance AD
substitute the values
Answer:
