15 tickets are yours.
250 * .06 = 15
You move the decimal point 2 places to the left because .6 is 60% instead of 6%
Answer:
i believe so
Step-by-step explanation:
Mean is the same thing as average
example
the mean of 30 and 40 is 35 because (30+40)/2=70/2=35
mean absolue deviation is when you take the mean of the set
then you find the diffference of each number of the set then take the mean of that
ex if yo uhave 1,2,3,4,5 and the mean is 3, then ou find the absolute value of the difference of each
|1-3|=2
|2-3|=1
|3-3|=0
|4-3|=1
|5-3|=2
add them and divide by 5
(2+1+0+1+2)/5=6/5= MAD=6/5
basically it tells how spread out the graph is or how close the points are to the mean
so the smaller mean average deviation, the closer the points are to the mean
the bigger it is, the farther they are
so if they had the points 1,2,3,4,5 and mean is 3 and MAD=6/5, 6/5 is small so therefor the points are close to that number
if I had the points 1,1,1,2,5,5 and the mean was 3 and MAD=11/5, 11/5 is bigger than 6/5 and therefor the points are more spread out
therefor the math scores are closer togeher
science is farther apart
if you mean that the highest grade in math was compared witht eh highest grade in science, then science is higher since the plots are more spread out
since math had a smaller MAD than science, the points are closer together
so the answers are C and D
