Answer:
9
Step-by-step explanation:
just do 16 - 5 its exactly the same
It would be the second one... y=3x^2+10
Answer:
Mean- 5
Median- 6
Mode- 6
Step-by-step explanation:
1. Place the numbers in order from smallest to biggest.
0,2,3,4,5,6,6,6,7,8,8
Finding the mean (average)- add all the numbers in thd data set together. Which would be 55. Then, you would divide that number by the number of the numbers in the data set. (11 numbers.) 55/11. 55 divided by 11 is 5, so that is your answer.
Finding the median- This is why we put the numbers in order. We are finding the number that is directly in the middle of the numbers. Mark one on each side until you get to the number in the middle. In this case, the median number will be 6.
Finding the mode- This one is easy. It's simply the number that repeats itself the most. In this case it would be 6 because it repeats itself 3 times.
Answer:
12/5 days
Step-by-step explanation:
if d=number of days
w=work completed
person one completes w=d/6 (ie. after 6 days (when d=6) work will be completed (w=1))
person two completes w=d/4 (ie. after 4 days (when d=4) work will be completed (w=1))
so total work competed together w=d/6 + d/4
the job is complete when w=1 so
1 = d/6 + d/4
12 = 2d + 3d
12 = 5d
d = 12/5
