Answer:
2
Step-by-step explanation:
-8-(-12)=4
1.8-12=-4
2.-8+12=4
3.-8-12=-20
4.-(8+12)=-4
Step 1: Add up all the scores.
Step 2: count the number of scores.
step 3: divide the sum of the scores by the number of scores themselves.
step 4: The answer is 26 points.
W = unknown number
7w - 8 = 3 (product of 7 and a number, w, subtract 8) is 3
7w = 11
w = 11/7
To find the mean: You have to add them all together, then divide them by how many numbers there are.
So: 23+25+32+35+36+25+27 = 203
How many numbers did we add up? 7.
203 ÷ 7 = 32.85714 (That is the mean rounded up to the nearest hundredth thousandth).
To find the mean you first add all the numbers up you get each day
12+16+0+8+31+28+17=112
Than you divided it by how many days there are...
112/7=16
So the mean is 16
