What two pairs of numbers have 10 as their LCM?
2 and 5 2 and 10 5 and 10
What is the average mean for -20 -20 -10 10 15 20 30 25 20 10 8 -20?
Add up all the numbers together and then divide by 12 to find the average mean:- 68/12 = 17/3 or as 5 and 2/3
Can two numbe215r have 20 as their HCF and 215 as their LCM?
No, 2 and 10 are factors of 20. The LCM of 2 and 10 is 10.
What 2 numbers have LCM of 20 and HCF of 2?
2 and 20 have an HCF of 2 and an LCM of 20. You could also use 4 and 10.
How many phone numbers can a person commit to memory?
An average person could commit to memory around 10-15 phone numbers.
The average of two numbers is 10 What is the sum of the two numbers?
Avreage = Sum/number of values So 10 = sum/2 Multiply both sides by 2: 20 = sum
What is the average of two number is 10?
Assuming mean average: average = sum/number_of_items → 10 = sum/2 → sum = 10 x 2 = 20 So any two numbers with a sum of 10 have a mean average of 10, eg {5, 15}, {1, 19}, {0, 20}, {-5, 25}, etc. With the median average, for two numbers it is exactly the same as the mean average, so any pair of numbers that sum to 20 will do. With the mode average, only the case of the pair of numbers {10, 10} will suffice.
How do you find the average in numbers?
Add the numbers then divide the sum by the number of numbers you added e.g. average of 1,2,3,4 four numbers add em up 1+2+3+4 =10 divide the sum by the number of numbers 10/4 average of 1,2,3,4 is 2.5
What is the average of 6 and 10?
To find the average of a group of numbers, add together all the numbers and divide by the number of numbers you have added together. In this instance, 6 + 10 = 16 / 2 = 8.
How to you work out the values when you have average and number of values?
There is not enough information. For example, 2 numbers, whose average is 10 could be -50 and 70 or 10 and 10 or 9 and 11 or 7.5 and 12.5 etc. All that you know in this case is that the sum of the two numbers = average*number of values = 10*2 = 20
What is the average of 7 2 9 22?
Sum of numbers = 40 Count of numbers = 4 Average = Sum/Count = 40/4 = 10
What number is halfway between -20 and 10?
The halfway point between two numbers is found by calculating the average of the two numbers. In this case, the average of -20 and 10 is (-20 + 10) / 2 = -10 / 2 = -5. Therefore, the number halfway between -20 and 10 is -5.
How do you find the sum and average of two integers?
Add the numbers together (sum) and divide by two (average). SUM: 2 + 8 = 10 AVG: 10 / 2 = 5
What is the average of the numbers 10 10 9?
The average is 9.66... recurring.
What is halfway between 10 and 90?
The halfway point between two numbers is found by taking the average of the two numbers. In this case, the average of 10 and 90 is (10 + 90) / 2 = 50. Therefore, the number halfway between 10 and 90 is 50.
What does the term average in Math means?
The term average (which can also be referred to as the mean) is where you add all of the numbers in a set and divide by how many numbers there are. For example, the average of 2, 3, 5, and 6. First, add all of the numbers. 2+3 = 5 5+5 = 10 10+6 = 16 or... 2+3+5+6 = 16 Lastly, you divide by the amount of numbers in the set. In this example, there are four numbers. Now, you divide by the total by the amount of numbers. 16/4 This equals 4, and you have your average (or mean)!
Which integer is halfway between -10 and plus 6?
That would be the average of those two numbers.The average of two numbers is half of their sum.1/2 (-10 + 6) = 1/2 (-4) = -2
