A 4-billion-bushel corn crop brings a price of $2.4/bushel. A commodity broker uses the following rule of thumb: If the crop is

reduced by x percent, then the price increases by 10x cents. Which crop size results in maximum revenue and what is the price per bushel? Revenue is equal to price times crop size. (Use decimal notation. Give your answers to two decimal places.) crop size__________.billion bushels price per bushel___________.$

Answer:

Step-by-step explanation:

The second crop size results in maximum revenue. The price per bushel of the second crop size is 3.54 dollars.

Step-by-step explanation: FIRST: Ensure all figures for price are in the same unit (same for quantity)

Hence, 10X cents = 0.1X dollars

SECOND:

Derive the equations for the new price and new quantity

P2 = P1 + 0.1X

Q2 = Q1 - (X% of Q1)

THIRD:

Input the values of Q1 and P1 into the equations

FOURTH:

To get X, equate P2 to Q2

P2 = Q2

From here, X = 11.4286

FIFTH:

Use this value of X to find the values of Q2 and P2 which will be 3.543 billion bushels and 3.54286 dollars respectively.

SIXTH:

The new revenue will now be 12.55 billion dollars which is obviously higher than the initial revenue of 9.6 billion dollars. Remember that R=P.Q

Revenue= Price x Quantity

How close are a meter and a yard? convert 1 meter into yards by using the fact

Serggg [28]

1 meter= 100cm

2.53cm=1 inch

12 inches= 1 foot

3 feet= 1 yard

2.53*12*3=91.08

1 yard=91.08cm
1 meter=100cm

1 meter is 8.92cm longer than 1 yard

Listed below are the amounts (dollars) it costs for marriage proposal packages at different baseball stadiums. Find the range,

yulyashka [42]

Answer:

Range = 2460 dollars, Variance = 516414.6 $dollars^2$ , Standard deviation = 718.6199 dollars . There are two outliers and they are likely to have much of an effect on the measures of variation.

Step-by-step explanation:

The smallest value in the sample data is min = 50 dollars and the largest value is max = 2500 dollars, therefore, the range is Range = max - min = 2500 - 40 = 2460 dollars. On the other hand, the formula to compute the sample variance is $S^2 = \frac{1}{n-1}\sum_{i=1}^{n} (x_{i}-\bar{x})^2$ where $\bar{x}$ is the sample mean, n is the sample size and the $x_{i}$ are the sample values. In this case the sample variance is $s^2$ = 516414.6 $dollars^2$ , the sample standard deviation is defined as the squared root of the sample variance, so, the sample standard deviation is s = 718.6199 dollars. There are two outliers because 1750 dollars and 2500 dollars are very different compared to the other values, these two numbers are very large and they are likely to have much of an effect on the measures of variation because these measures are sensible to outliers, they are no robust measures.
