MATHEMATICS MIDDLE SCHOOL

I don’t get this. Can any help me

Answers

Answer 1

Answer:

The average is the sum of the observations divided by the count.

So the sum of the observations is the count times the average.

So the 9 teachers together make 9(1000)=$9000 per week. The 20 staff (9 teachers + 11 aps) makes 20(1275)=25500.

So the 11 aps must make 25500-9000=16500

So the mean ap salary is 16500/11 =$1500 per week

Clearly management is where it's at.

Check: (1500*11+1000*9)/20 = 1275 good

Choice B

Answer 2

Answer: The answer is b. Or 1,500.

What is the median for the numbers 3.60, 3.80, 5.44, 5.52, 5.72, 7.22?I know it's between 5.44 and 5.52

Answers

okay so first of all we need to know the definition of our median first*
median: Given any group of numbers we put the numbers in order from least to greatest then find the number that's right in the middle.
Here ill show you how we do it:)
3.60, 3.80, 5.44, 5.52, 5.72, 7.22?
its already in order for us:)
but when we find the middle number it turns out that we have two middle numbers:/
simple:) all we do is take the two numbers add them together and divide by two
since our middle numbers are 5.44 and 5.52 we are going to use these:)
first add!
5.44 + 5.52 = 10.96
now divide that by 2
10.96 ÷ 2 = 5.48
so our median for this set of numbers is
5.48!
hope this helps;)

The answer is 5.48 because the middle numbers are 5.44 and 5.52 so what you do is find the mean or average of the two numbers by adding them together then dividing them by two, so: (5.44 + 5.52) / 2 = 5.48

Are the following equations (1,2,3) one solution, infinitely many solutions, or no solution for each one? Please and Thank You 1.

y-3x=5

y=3x+5

2.

y=6x+2

y=6x-2

3.

y=5x+9

y=3x-2

Answers

1.when you change the first equation to the form it is the same as the second which means infinite solutions

y-3x=5 --->y=3x+5 then set them equal to find many possible solutions

2.this is no solution because the slopes are the same when you combine these equation the 2's cancel out and you ar left with y=12x which cannot be solved

3.when everything is different there is one solution
