- help plz what is Mean, Median and Mode?

The arithmetic mean is found by adding the numbers and dividing the sum by the number of numbers in the list. ... This is what is most often meant by an average. The median is the middle value in a list ordered from smallest to largest. The mode is the most frequently occurring value on the list.

See below

Step-by-step explanation:

The mean of a data set is what the average value is. For example, the mean of 3, 6, and 9 is (3+6+9)/3 = 18/3 = 6.

The median of a data set is the middlemost value from least to greatest. For example, in {3,6,9}, the median is 6 because it's the middlemost value.

The mode of a data set is the most frequent value. For example, in {1,1,2,2,2,3,5,6,6}, we can see that the mode is 2 because it appears the most frequently in the data set.

46.2+112.3

step-by-step explanation:

distance covered by pamela in 9 l of fuel = 99km

let us apply unitary method here.

distance covered by pamela in 1 l of fuel =99/9 =11 km

now let us find distance covered by pamela if she has 12 l of fuel.

distance covered in 12 l = distance covered in 1 l of fuel * 12

we know that distance covered by here in 1 l is 11 km.

so distance covered in 12 l of fuel = 11*12 = 132 km.
