Answer:
1. 23
2. 8
3. 64
4. 26
5. 192
6. 600
Mean = 18.8
Step-by-step explanation:
Mean = (Sum of all values)/(Number of values)
Mean = (12 + 15 + 18 + 23 + 26)/5
Mean = 94/5
Median: 6
1,2,3,3,4,4,5,5,5,6,6,6,6,7,7,7,8,8,8,9,9,11
half of 22 (total numbers) is 11, on the 11th spot it is 6
His work should have looked like this.
2x + y = 5 x − 2y = 10 y = 5 − 2x x − 2(5 − 2x) = 10 x − 10 + 4x = 10 5x − 10 = 10 When he added in both sides, he subtracted 10 from 10, 5x = 20 instead of adding 10 from 10 to make 20. x = 4 2(4) + y = 58 + y = 5
y = -3
create a graph
like this
X Y
-3
0
3
and solve for y
