During a sports competition, students participated in races of various distances. The data is shown in the frequency table. What is the range of lengths of the various races?

Answers

Answer:

150

Step-by-step explanation:

I believe the lengths are on the left and to find a range you subtract the largest and smallest numbers. In this case the largest number is 200 and the smallest is 50.

And 200-50=150

Hence, the range is 150.

what is range?

The range is the difference between the largest and smallest numbers. The midrange is the average of the largest and smallest number.

How to solve?

We know that,

highest distance(meters) = 200

lowest distance(meters) = 50

Hence, Range = 200-50 = 150

For each diagram, decide if y is an increase or a decrease of x. Then determine the percentage.

Answers

Answer:
In A: y is a 25% decrease of x
In B: y is a 25% increase of x
Step-by-sep explanation:
For A:
The diagram in A shows that x = 4, while y = 3.
Thus, this means that y decreased by 1, relative to x.
The percentage decease would be:

Therefore, y is a 25% decrease of x.
For B:
The diagram for B shows that x = 4, while y = 5.
Thus, this means that y increased by 1, relative to x.
The percentage increase would be:

Therefore, y is a 25% increase of x.
