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:
X=3
Step-by-step explanation:
11=3(X × ⅓) +8
11=3(X/3) +8
11-8=X
X=3
The first thing we are going to do for this case is define variables.
We have then:
x: Amount of soybean meal
320 - x: quantity of cornmeal
We now write the equation that models the problem:

Rewriting we have:

From here, we clear x:

Then, the amount of Soybean meal is:

The amount of cornmeal is:
Answer:
cornmeal: 280 lb
Soybean: 40 lb.
With 20 tickets sold the revenue would be 30
With 2 it would be $3
Therefore 1 ticket would have a $1.50 revenue
$16.75, because 33% of 25 which is (25x 0.33) =8.25. This is the amount deducted. 25-8.25=16.25
