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

Mike and Andy are each reading the same book. Mike read 2/4 of the book on Tuesday and 1/3 of the book on Wednesday. Andy read 1/2 of the book on Tuesday and 1/5 of the book on Wednesday. Andy says that altogether he read more of the book on Tuesday and Wednesday than Mike. Is Andy correct?


Select from the drop-down list to complete the sentence. Explain your answer by typing in the box.


is andy correct or incorrect




Explanation:
ASAP

Answers

Andy is wrong, on tuesday they read the same amount, but on wednesday mike read more than andy because 1/3>1/5 so mike read more altogether, hope this helps :) plz give branliest if it does

In the second attempt, Mike read (1/3)rd of the book which is more than

(1/5)th of the book Andy read.

What is a fraction?

A fraction is written in the form of p/q, where q ≠ 0.

Fractions are of two types they are proper fractions in which the numerator is smaller than the denominator and improper fractions where the numerator is greater than the denominator.

Given,  Mike read 2/4 of the book on Tuesday and 1/3 of the book on Wednesday.

Therefore in total, Mike read (2/4 + 1/3) of the book.

= (6 + 4)/12.

= 10/12.

= 5/6 of the book.

Also given, Andy read 1/2 of the book on Tuesday and 1/5 of the book on Wednesday.

Therefore in total, Andy read (1/2 + 1/5) of the book.

= (5 + 2)/10.

= 7/10.

As the fractions (2/4) which Mike read and (1/2) Andy read they have read the same amount of the book but in the next time Mike read 1/3 of the book and 1/5 and we know 1/3 is greater than 1/5.

So, Mike read more of the book than Andy.

Answer: 0.11

Step-by-step explanation: (2/3) / 6 = 0.11

This question is simple. Do not worry. I will get it done for you. What we need to do here is to divide 2/3 by 6 because you have 2/3 of the salad leftover and you want to split it among 6 friends. 6/1 is the same as 6 because if you divide 6 and 1, you get 6. Hence, 2/3 / 6/1. However, we need to flip the second fraction. So, 6 is the denominator and 1 is the numerator. When we do that, the question is now a multiplication question.

2/3 x 1/6 = 2/18

However, the fraction can be simplified by dividing both sides by 2.

2/2 x 18/2 = 1/9

Hence, each friend receives 1/9 of the salad.
