Answer:
62 minutes.
Step-by-step explanation:
To find the mean, you need to <u>add</u> together all of your values (the minutes) and <u>divide</u> them by the number of values (how many sets of minutes given).
So, choosing to add 62 minutes:
38 + 40 + 40 + 42 + 43 + 50 + 62 = 315
There are 7 sets of minutes in total, so we then divide 315 by 7.
315/7 = 45 minutes
Therefore, running 62 minutes on the seventh day would cause you to run a mean of 45 minutes per day for the week.
Step-by-step explanation:
to find mean
add all numbers, then divide by how many set they given
to find median
you need to arrange them ascending order
then what is the number in the middle
to find mode
find what most repeated number
Answer:
Step-by-step explanation:
Let x represent the larger number.
Let y represent the smaller number.
The sum of two numbers is thirty seven. This means that the smaller number would be 37 - x
The translation into a variable expression for the the difference between nine more than twice the larger number and the sum of the smaller number and three would be
2x + 9 - (37 - x + 3)
Opening the parenthesis and putting the constants together, it becomes
2x + 9 - 37 + x - 3
2x + x + 9 - 37 - 3
3x - 31
