4. .36 km/h

## Ans 8:

Class : Class 7
The slowest speed among the options is 4. .36km/h . Let us see why...First lets convert all the options to decimal form:-Option 1 is 3.6 km/h, option 2 is 36.0 km/h, option 3 is 360.0 km/h and option 4 is 0.36 km\h. The descending order for these numbers is 360.0 km/h, 36.0 km/h, 3.6 km/h and finally 0.36 km/h. Hence, we can conclude that that .36 km/h is the slowest speed.

MEDIAN IS THE MID VALUE OF THE DATA ARRANGED IN ASCENDING ORER........ MODE IS THE VALUE IN THE DATA WHICH HAS MOST FREQUENTLY OCCURED.......

## Ans 3:

Class : Class 7
middle number of a given data is called its median most occouring number of a given data is called its mode

## Ans 4:

Class : Class 7
The median, as the name suggests, is the middle number of a set of numbers. For example, in 23, 24, 25, 26, and 27, 25 is the median. In case of an even number of numbers in your set, take the average(mean) of the two numbers. For example, in 23, 24, 25, and 26, You would be taking the average of 24 and 25. Average= (24+25)/2 Ans= 49/2 Ans= 24.5 Therefore, 24.5 is your median in this case. The mode, is the value in a set of numbers that occurs most frequently. For example, in the numbers 37,35,24,46,68,37, and 93, 37 is the mode as it occurs twice and the other numbers are only occurring once. Remember, if there are two numbers that are repeated for the same number of times, and they are the greatest in value, then you could be having two modes. For example, in the numbers 37,35,24,46,68,37, and 35, 37 and 35 are the modes.

We have, 1^3+2^3...10^3 = {10(10+1)/2}^2 1^3+2^3...10^3 = 55^2 1^3+2^3...10^3 = 3025
