On the most recent district-wide math exam, a random sample of students earned the following scores:
95,45,37,82,90,100,91,78,67,84,85,8 5,82,91,93,92,75,84,100,59,92,77,68 ,88

what is the mean score, rounded to the nearest hundredth?

what is the median score?

mean=80.833

median=84.5

Step-by-step explanation:

scores:

95,45,37,82,90,100,91,78,67,84,85,85,82,91,93,92,75,84,100,59,92,77,68,88

we arrange the scores in ascending order

37,45,59,67,68,75,77,78,82,82,84,84,85,85,88,90,91,91,92,92,93,95,100,100

mean=sum of all observations/total number of observations

        = 1940/24

        =80.833

median is the central tendency of all observations

median lies between 84 and 85

median=(84+85)/2

           = 84.5

step-by-step explanation:

the original amount doesn't ''re just looking for the time it takes for 1/2 of the substance to we have

(1/2) =)     take the ln   of both sides

ln (1/2)   = )   and we can write

ln(1/2) = ) lne     and lne   = 1     so we have

ln(1/2) = -.1092t     divide both sides by -.1092

t = ln(1/2)/-.1092 = about 6.347 days = about 6.3 days (rounded)
