Answer:
Data Set A = 6.5
Data Set B = 4
Step-by-step explanation:
The mean is just the average. It's calculated by adding up the scores and dividing the total by the number of scores in the group altogether.
For Data set A, you add 4 + 4 + 5 + 6 + 7 + 8 + 9 + 9 = 52
Then divide the total by how many numbers are in the set.
In this case, 52 ÷ 8 = 6.5
For Data set B, do the same. 3 + 3 + 3 + 4 + 4 + 5 + 5 + 5 = 32 32 ÷ 8 = 4
Answer:
k = -10
Step-by-step explanation:
Did you try adding all the sides like this: 6+2+6+12+16+6+12=?
Hope this picture helps! ;) Ignore the stuff around it ($12 or the triangle)
Y= 250000-8750t
3.5 percent of 250000 is 8750, if that’s the amount decreasing each (t) years, you multiply that number by number of years taken into account.
