ANSWER: 14
Hello!
First of all, we need to find the mean. To find it, we add up all of the scores and divide by the number of tests.
85+93+78+90+88+97+88=619
619/7≈88.43
Mean≈88.43
Now we need to find the median. First we order the numbers from least to greatest.
78,85,88,88,90,93,97
Now we have to find the middle number. As you can see, the number in the middle is 88.
Median: 88
Finally, we need to find the mode. This is the number that appears the most. As you can see, 88 appears twice, while all of the others appear only once. Therefore, our mode is 88.
Mode:88
I hope this helps!

Answer:
Their expenses and sales will both equal at 200 ounces.
Step-by-step explanation:
This can be determined using the break-even point in ounce formula as follows:
Break even point in ounce = Fixed cost / Contribution per ounce
Where;
Fixed cost = Advertising = $600
Contribution per ounce = Selling price per ounce - Cost per ounce = $4 - $1 = $3
Substituting the values into equation (1), we have:
Break even point in ounce = $600 / $3 = 200 ounces
Therefore, their expenses and sales will both equal at 200 ounces.
Suppose that executive decides to invest X Dollars on the 8% annual
interest investment. so that means that he would invest the remaining
money on investment with 6% annual interests, which is = (26,000-X)
Total annual return he will get on 8% annual interest investment would be: X/100*8
Total annual return he will get on 6% annual interest investment would be: (26,000-X)*6 /100
We know that total annual return he got was $1,860 which is the sum of annual return of both the investments.
So: X*8/100 + (26,000-X)*6/100 = 1860
We now have a equation with only one variable X and we can find its value by solving this simple equation.
1860= 8X/100 + (26,000-X)*6/100
1860 = 8X/100+ 156000-6X/100
1860 = (8X+ 156000-6X)/100
186000 = 2X + 156000
186000 - 156000 = 2X
30000 = 2X
30000/2 = X
15000 = X
so X= 15000 and Y= 26000-15000 which is 11,000.
Executive invests 15,000 on the 8% annual interest investment and He invests 11,000 on the 6% investment.
