How do you find the median

2 answers:

4 0

In a list of numbers, such as 1,2,3,4,5,6,7, start from the right and cross off the last number. In this case, it's the 7. Then, go to the left and cross of the first number, the one. Keep going from right to left, and when you get down to one number in the middle, that is the median. However if there are two numbers in the middle, I think that you have to find the mean of those two numbers, and that should be the median. That's only if there are two numbers left in the middle. Hope this helps!

The median is the middle score for a set of data that has been arranged in order of magnitude.

So order your vales, and then pick the middle record.

This works fine when you have an odd number of scores.

BUT

What happens when you have an even number of scores?

It is easy...

You would calculate the mean of the two middle records ..

in other words:
you simply have to add up the middle two scores and average the result.

I hope that helps!

Answer:

So I would say your answer is..............A

Step-by-step explanation:

For most places, global warming will result in more frequent hot days and fewer cool days, with the greatest warming occurring over land. Longer, more intense heat waves will become more common. Storms, floods, and droughts will generally be more severe as precipitation patterns change

Also, A is correct because lets say you put an ice cube in the sun...okay well if it keeps getting hotter and hotter multiply ice cubes into ice caps. Well same thing will happen. It will melt causeing water from the ice caps. Which will result into more water. Which will cause water to go above sea level!

Hope this helps!!!

The sum of two positive integers, a and b, is at least 30. The difference of the two integers is at least 10. If b is th

Dafna11 [192]

Answer:

$a + b \geq 30$

$b - a \geq 10$

Step-by-step explanation:

Given

The sum of the two positive integer a and b is at least 30, this means the sum of the two positive integer is 30 or greater than 30, so we write the inequalities as below.

$a + b \geq 30$

The difference of the two integers is at least 10, if b is the greater integer then we subtract integer a from integer b, so we write the inequality as below.

$b - a \geq 10$

Therefore, the following system of inequalities could represent the values of two positive integers a and b.

$a + b \geq 30$

$b - a \geq 10$
