Answer:

(a) 20.9 years.

(b) 34 years old.

Step-by-step explanation:

Well for part a, just multiply the ages by their respective frequencies, and add them and divide by 11. You would get 20.90909091, so the mean age is about 20.9.

For part b, there would be 12 players with a mean age of 22. Their ages would add up to be 12 * 22 = 264.

The original 11 players' ages add up to be 230. 264 - 230 = 34. So, the new player is 34 years old.

Hope this helps!

The base of a triangle is represented by (2x − 6) and the height by (x − 2). Which polynomial expression BEST represents the are
BabaBlast [244]
Area of a triangle= \frac{1}{2} *base*height
A=\frac{1}{2} *(2x-6)*(x-2)
A=\frac{1}{2} ( 2x^{2} -4x-6x+12)
A=x^{2} -2x-3x+6
A=x^{2} -5x+6

What is the solution to the system of equations?<br><br> 6x – 9y = 16<br><br> 2x – 3y = 7
kifflom [539]
The first step for solving this problem is to multiply both sides of the bottom equation by -3.
\left \{ {{6x-9y=16} \atop {-6x + 9y = -21}} \right.
Add the two equations together.
6x - 9y - 6x + 9y = 16 - 21
Eliminate the opposites.
-9y + 9y = 16 - 21
Remember that the sum of two opposites equals 0,, so the equation becomes the following:
0 = 16 - 21
Calculate the difference on the right side of the equation.
0 = -5
This means that the statement \left \{ {{6x-9y=16} \atop {2x-3y=7}} \right. is false for any value of x and y. That means that the answer to your question is (x,y) ∈ ∅,, or no solution.
Let me know if you have any further questions.
