Answer:
b(x) = -2x² + 7x + 114
Step-by-step explanation:
Step-by-step explanation:
First we convert 50 cent into dollar,
1 cent = dollar
1 cent = 0.01 dollar
50 cent = 0.5 dollar
According to question,
x is the number of 50¢=$0.5 price increases.
b(x) is the revenue generated
He currently charges $3 per book.
i.e. price of book = 3+0.5x
Quantity or average = 38 per day
According to a study, for every 50¢ increase in rental price, the average business can expect to lose 4 rentals a day.
i.e. quantity became 38-4x
Revenue = Price × Quantity
The required equation is given by,
Answer:
The options 2,3 and 5 are correct.
Step-by-step explanation:
From the figure it is noticed that the points U,V and W are midpoint of JK,KL and JL respectively.
Midpoints theorem of triangle states that the line connecting the midpoints of two sides is parallel to third side and its length is half of the third side.
The points U and W are midpoint of JK and JL. Using midpoint theorem, we get


The points U and V are midpoint of JK and KL. Using midpoint theorem, we get


The points V and W are midpoint of KL and JL. Using midpoint theorem, we get



Therefore options 2, 3 and 5 are correct.

Answer: It would be d,15m
Answer:
86.7%
Step-by-step explanation:
For questions regarding values related to a normal distribution, a suitable calculator is required. Numerous calculators, apps, web sites, and spreadsheets are capable of answering this question.
__
One standard deviation above the mean is 327 +27 = 354, so the value is expected to be slightly more than 50% +34% = 84%. It is no surprise, then, that a calculator tells you 86.7% of the data is below 857.
_____
<em>Additional comment</em>
The "empirical rule" tells you 68% of the area is within 1 standard deviation of the mean. The distribution is symmetrical, so half that, 34%, is between the mean and 1 standard deviation above the mean. Of course, 50% of the data is below the mean.
