How do you get the Median?
Place the numbers in order from least to greatest and cross each one off from each side. The number that is left is the median. If two numbers are left find the middle of those numbers 1,2,3,4,5 3 is the median 1,2,3,4,5,6 3.5 is the median
All the numbers from 1 to 99 are multiplied together Use a pattern to determine the last digit of the product?
As the numbers 1 to 99 are multiplied together, one factor of the product will be 10 which means the last digit must be 0 (a zero). Without working out the product, it can be seen that every multiple of 5 in the original numbers can be paired up with an even number (that is not a multiple of five) and multiplied together (which produces a multiple of 10) which are all factors of the product together; thus the product will ends with that number of zeros: there are 19 multiples of 5 in the numbers 1-99, so the last 19 digits of the product are all 0 (zero).
What is A grouping of data into categories giving the number of observations in each category is called?
It is called grouping data.
Try to put the numbers 1 to 7 in the seven diamonds below so that the numbers in each row of three diamonds add up to 10 Each number can be used only once?
There are no seven diamonds below.
How many 5 digit numbers that end with 0 are there?
Assuming positive integers, and no leading zeros, the range of five digit numbers is 10000 to 99999. The ones that end in zero can be found by taking the four digit numbers: 1000 to 9999 and multiplying each by ten. {1000,1001, 1002, ...9999}, multiplied by ten is {10000,10010,10020,....99990}. There are 9000 of them.
