a) 20.9
The mean is calculated by adding up the scores and dividing the total by the number of scores, it is also called the average.
First, we can count and see there are 11 players (makes sense for a football team). Adding up the ages gives us 19 + 19 + 20 + 20 + 20 + 21 + 22 + 22 + 22 + 22 + 23 = 230. Divide by 11 and we get a mean of of about 20.9!
b) 30
To figure this out, we will set up an equation that looks like this:
[tex]\frac{19 + 19 + 20 + 20 + 20 + 21 + 22 + 22 + 22 + 22 + 23+x}{12} =22[/tex]
And now we will solve:
[multiply both sides by 12] 230 + x = 264
[subtract 130 from both sides] x = 30
So the age of the new player should be 30!
Have a nice day!

ill give you braindeath if you get this right
Answer:
The larger angle is 144 degrees and the smaller angle is 36 degrees
Step-by-step explanation:
Because this is a supplementary angle you have to find out what x is to solve this equation [tex]2.4x+9.6x=180[/tex]
Because 2.4x and 9.6x are like terms we add them [tex]2.4x+9.6x=12x[/tex]
So now to find x we divide 180 by 12 to get 15 [tex]\frac{12x}{12} =\frac{180}{12}[/tex]
We replace the x with 15 [tex]2.4(15)+9.6(15)=36+144[/tex]
We add 36 and 144 which equals 180
Using subsitution, which value of x makes this equation true? x+1/6=1
x=13
x=23
x=56
x=76
Answer:
5/6
