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.
Answer:10
Step-by-step explanation:
Each exterior angle is (3x + 6)°
A decagon has 10 sides
Each exterior angle=360/n
n=number of sides
3x+6=360/10
Cross multiply
10(3x + 6)=360
30x+60=360
Collect like terms
30x=360-60
30x=300
Divide both sides by 30
30x/30=300/30
x=10
