2 answers:
<h2>Answer:</h2>
The number of points she earned in the next game is:
16
<h2>Step-by-step explanation:</h2>The scores of the six games is given by:
9, 12, 10, 8, 14, and 15.
Now, let the score in the next game be: x
We know that the average of the scores is the sum of all the score to the total number of scores.
Here the sum of all the scores is:
9+12+10+8+14+15+x=68+x
Also, number of scores= 7

Answer:
157.1
Step-by-step explanation:
If you split the blue shape like in the picture, it shows that there is 1 large semicircle and 2 smaller ones.
The area of a semicircle is (pi×radius²)÷2
First, you would find out the area of the large semicircle by substituting in the numbers:
(3.142×10²)÷2=157.1
Then you would find out the area of the smaller semicircle:
The diameter of the semicircle is 10 so to find the radius you would half it.
(3.142×5²)÷2=39.275
To find the area of the whole shape, you would have to take away 39.275 and then add it back on so the answer would be 157.1
Hope this helps :)
