Can someone show me how to do Mean absolute deviationWhat is the means-to-MAD ratio of the two data sets, expressed as a decimal? Data set Mean Mean absolute deviation (MAD) 1 10.7 2.4 2 13.7 2.5
Answers
To find the mean of a set, add up all of the numbers and divide by how many numbers you have. For the first set:
For the second set:
To find the mean absolute deviation, (MAD) find the mean of the distances of each number from the mean. For the first set:
For the second set:
Note that when you only have two data points the mean is directly between them, which is why the distances are the same.
The means-to-MAD ratio is simply that, divide one by the other and that's it. For the first set:
For the second set:
What is 2x6÷2+1 help me!
Answers
2×6÷2+1 =12÷2+1 =6+1 =7
You would first multiply the 2 and the 6 to get 12. Then you would divide the 12 by the 2 and get 6. Finally you would add one to 6 and get 7
1 ) what is 175 % of 85? 2 ) 76 is 80 % of what number?
3 ) 96 is 160 % of what number?
4 ) what is 85 % of 120?
5 ) 56 is 75 % of what number?
Answers
well if 100% of 85 is 85, the answer is going to be more than that. the multiplication is 175 x 85 =14875 /100 = 148.75. 1) if 100% of 85 is 85; 2) What is the remaining 75% 85 x 3/4 => 85 x3=255 => 255/4 =>63.75 therefore 175% => 85 + 63.75 = 148.75.
Two problems here- 1) Find the total cost to the nearest cent, $100 dinner; 20% gratuity 2) Find the total cost to the nearest cent, 12300 car; 5% sales tax
Answers
In both of these problems you are asked to find a percentage of another number and then add it to that number... In math
"is" means = "of" means ×
1) In the first problem 20% of 100 is, means 20% × 100 = .20 × 100 = $20
now add it to the cost of the meal.
100 + 20 = $120 (final cost)
___________________
2) In the second problem 5% of 12300 is, means 5% × 12300 = .05 × 12300 = $615
add this to the original price for the final cost...
12300 + 615 = $12,915
