What is the median of the following set of data?

19, 45, 62, 5, 23, 45, 98, 11

Answers

Answer 1
Answer: Re-arrange the set of data in order from smallest to biggest.

= 5, 11, 19, 23, 45, 45, 62, 98. 

So let's take the two middle values and subtract.

23 - 45

Middle value = 22
Answer 2
Answer: First u arrange da numbers in order from smallest to biggest:
5, 11, 19, 23, 45, 45, 62, 98
If it was a data set of an odd number (For example 9 numbers then u would get da fifth number as da median), but this is an even number of 8 numbers.
So u have to add da two numbers in da middle n divide by 2 (in this case 23+45÷2=34

The candidates for mayor had 2 debates. The first debates lasted 2/3 hour. The second debate was 3 times as long as the first one. How many hours long was the second debate?

AC = 4, AE = 7, AD = 10, what is the length of AB?


PLZ HELP

Answers

The above answer is not correct! The correct way to solve this is to look at the ratio of the sides as these are similar triangles. We are told that AC = 4 and AE = 7. That means that the side AC has been multiplied by 7/4 in order to become the length AE. Because these are similar trianges, all the sides must be multiplied by the same amount - therefore the side AD is equal to the length of AB multiplied by 7/4. Because we are given the side AD and need to find AB, we simply run the process in reverse like so:
If AD = 7/4 x AB:
AB = 4/7 x AD
AB = 4/7 x 10
AB = 40/7 (5.71 as a decimal)
Hope I helped :))

Answer:

The length of AB is 1 3/7 .
