Answers
1. The correct histogram (attached) that captures the frequency distribution is Option C.
2. Whether the data appear to have a distribution that is approximately normal, A. No, it is not symmetric.
What is a symmetric distribution?A symmetric distribution is a distribution in which the left and right sides mirror each other and it is a normal distribution, with a distinct bell shape.
In a symmetrical distribution, mean = median = mode. It is a skewed distribution when it is not symmetrical.

Find the first five terms of the recursive sequence. Show all your work. an = 3a n-1 - 6 where a1 = 7

All whole numbers can also be classified as
integers and rational numbers.
True
False
Answers
Answer:
True
Step-by-step explanation:
We use definitions to help us in this problem. The definition of an integer is a whole number that is not a fraction or has any fractional value. This definition includes all whole numbers, so we know that all whole numbers can be classified as integers. That's one condition done. The definition of a rational number is a number that can be written as a fraction. All whole numbers can be written as a fraction (i.e. 12/1, -3/1, 10000/1). This means that all whole numbers are also rational numbers, giving us our final answer of True.

Interns,
Mr. Howell, the prestigious founder and owner of our company Coal is Gold Electricity would like you to perform an
analysis on the company’s emission control. The government is providing subsidies to encourage reducing emissions.
Mr. Howell would like to know is it worth reducing emissions with the subsidy. The pertinent information can be found
in Mr. Howell’s email below.
“Mr. Kleppin,
As you know, my company has supplied the energy needs of the entire state since 1968! I can’t believe they are
demanding that we reduce our emissions! This will force us to pass on the increase in the cost to our customers!
Thankfully, the government will be providing a subsidy to offset these costs! The current subsidy is $500 per pound of
pollution reduction each day with a minimum reduction of 15 pounds per day. I have spoken to the engineering
department regarding the cost to reduce emissions. They informed me that the average daily cost to us is a fixed daily
cost of $100 in addition to $30 times the square of the quantity of pounds of pollution reduced each day. Currently, I
would like to reduce emissions by 15 pounds of pollutant per day. At this level, what is the marginal average daily cost of
reducing emissions to 16 pounds of pollutant per day? What is the average daily cost at this reduction level? Is the
average daily cost increasing or decreasing at this reduction level? With the government subsidy, what would be our
average daily cost for reducing emissions by 15 pounds of pollutant per day? The government would like us to reduce
emissions by 20 pounds of pollutants per day. Could we accomplish this with no cost to us? If not, at what reduction level
would we have no cost to us? What do you recommend? I would like you, Mr. Kleppin, to give the interns a chance to
earn one of the 10 available positions at the end of their internship by giving them the opportunity to do the analysis.”

(i) Marginal Cost of a 16-pound reduction in emissions = 7680 - 6750
= $930
(ii) Average Price at a decline of 15-pound = 6850 / 15 = $456.67
( Every additional unit results in an increase in Variable Cost per unit. The Average Cost will thus rise as the amount increases. )
(iii) Since our expenses are less than the subsidies in pounds (15), there will be no net cost.
(iv) It will cost us $12,000 to maintain the decrease level at 20 pounds, of which the corporation may recoup $10,000. Thus, the final price will be $2100.
(v) Break Even can be calculated between 16-17 pounds (You can refer to the table for the clarifications)

Find the after-tax return to a corporation that buys a share of preferred stock at $49, sells it at year-end at $49, and receives a $4 year-end dividend. The firm is in the 21% tax bracket.
This is what I got so far:
Before-tax:
(49-49)+4 = 4,
4/49 = 0.0816,
After-tax:
0.0816 (1-021) = 0.06448 or 6.45%
Answers
Based on the calculation below, the after-tax return to the corporation is $3.16 per share or 6.44% if expressed in percentage.
How do we calculate the after-tax return?The after-tax return can be calculated using the following formula:
After-tax return = Total return * ( 100% - tax rate) .............. (1)
Where:
Total return Received = Dividend received + Change in price = $4 + ($49 - $49 ) = $4 + $0 = $4
Tax rate = 21%
Substituting the values into equation (1), we have:
After tax return = $4 * ( 100% - 21%)
After-tax return = $3.16 per share
The after-tax return can also be expressed in percentages as follows:
After-tax return in percentage = After-tax return / Share price = $3.16 / $49 = 0.06444897 = 6.44%

I dont understand the problem i think it's 4.5 but i dont know
Answers
Answer:
probably 4.5
"Step-by-step explanation:
To break even, we need the total profit to be equal to 0. If we make x dollars in 2012, then we need to solve
2.5 + 1.75 + (-3.3) + (-1.4) + x = 0
This gives us x = 0.45 in thousands.
Since the question asks us to give the answer in hundreds, we multiply by 10 and get 4.5. Thus the profit in 2012 must be 4.5 (in hundreds) to break even."

Answers
Answer:

Step-by-step explanation:
You want the smaller of the two factors of 896 that have the ratio 8:7.
SetupLet x represent the smaller of the two factors (the one we want to find). Then the larger factor is (8/7)x, and their product is ...
x(8/7)x = 896
(8/7)x² = 896
SolutionMultiplying by the inverse of the coefficient of x², we have ...
x² = (7/8)(896) = 784
x = √784 = 28 . . . . . . . . take square root
The smaller of the two numbers is 28.

You want to buy a $193,000 home. You plan to pay 5% as a down payment, and take out a 30 year loan for the rest.
Answers
Answer:
Down Payment = 5% of 168,000. You finance 95% of 168,000 which is the PV of your payments.
Use the same annuity formula as in your student loan question with monthly rate = 7%/12 and t=12*30 =360 months. That will give you your payment amount.
you will make 360 payments so total Payments = 360*pmt. Total Payments less principal = total interest paid.

the fixed point is called the focus and the fixed line is directrix and the ratio is the eccentricity.
The general equation for the vertical hyperbola is
[ (y-k)^2 / a^2 ] – [ (x-h)^2 / b^2 ] = 1
The conjugate axis of the vertical hyperbola is y = k

We have data on the weights in grams of 5 baby pythons. Their mean weight is 31.8 and the standard deviation of the weights is 2.79 . The correct units for the standard deviation is Grams.
According to the question statement, We have data on the weights in grams of 5 baby pythons. Their mean weight is 31.8 and the standard deviation of the weights is 2.79.
The correct units for the standard deviation is Grams because the unit of standard deviation is the unit of simple data and the unit of variance is the square of the simple data unit.
And as we know the unit of weight is Grams only hence we conclude that Grams is the correct unit of standard deviation.
Standard Deviation: Abbreviated as SD and standard deviation is a measure of the amount of variation of a set of values. A low standard deviation indicates that the values tend to be close to the mean (expected value) of the set, while a more or high SD indicates that the values are spread out over a wider range.To learn more about standard deviation, click on the given link below

when two items are thrown from the same height how does it affect the two in different ways if so
Answers
The height from which any two objects is thrown affects their time of motion, the greater the height, the more time the objects spend in air and vice versa.
What is time of motion?
The time of motion of an object is the time taken for an object to travel from point of projection to the projection plane or it can be said as the time a projected object spent in air.
The time taken for an object dropped from a certain height is calculated as follows;
h = vt + ¹/₂gt²
where;
h is the height from the which the object is droppedv is the initial vertical velocity of the objectt is the time of motion of the objectg is acceleration due to gravitywhen the object is dropped from rest, v = 0
h = ¹/₂gt²
t = √(2h/g)
