Make Sense and Preserve. Grade 9 Council is raising money for class dances by selling spirit T-
Ugo [173]

Answer:

4 dollars or 13 dollars

Step-by-step explanation:

Revenue is the income or increase in net assets that a commercial organization have as a result of offering services.

Revenue is the product of selling price per goods and the number of goods sold. That is:

Revenue = selling price per goods * number of goods sold

Given the revenue function:

R=-n² +17n +200; where n is the increase in the original price of T-shirt.

Since the council wants to make a revenue of $250, hence:

-n² +17n +200 = 250

-n² + 17n - 50 = 0

Solving using a calculator gives:

n = $4 or $13  (to the nearest whole number)

Help please!<33:) i dont really understand it
belka [17]

Answer:

4. 8/15

Step-by-step explanation:

I will do #4. For dividing fractions, you multiply them together and remember to flip the second one.

Example: Instead of 2/5 divided by 3/4, it would be (2/5)(4/3), which = 8/15. Multiply the 2 and the 4 to get 8, then multiply the 5 and the 3 to get 15.

When Sophia runs the 400 meter dash, her finishing times are normally distributed with a mean of 75 seconds and a standard devia
alukav5142 [94]

Answer: 90% of the time.

Step-by-step explanation: This is because you can add the two different times and the standard time of 75 seconds, divide it all by 3 leaving you with 75.2 and that is 0.2 away from the original between those times all together. Take that 0.2 and subtract it from the 1.1 deviation and you’ll get 0.9 times that by 100 and you get it in a percentage; 90%.
