Answer: 45/10
Explanation:
We want to add
11/5 + 23/10
The first step is to find the lowest common multiple, LCM of the denominators. The LCM of 5 and 10 is 10. We would divide the LCM by each denominator and multiply each numerator by the results. The common denominator of the final fraction would be the LCM. We have
For the first fraction,
10/5 = 2
2 x 11 = 22
For the second fraction,
10/10 = 1
1 x 23 = 23
Thus, the final fraction would be
(22 + 23)/10
= 45/10

Ghost, Inc., has no debt outstanding and a total market value of $395,600. Earnings before interest and taxes, EBIT, are projected to be $53,000 if economic conditions are normal. If there is strong expansion in the economy, then EBIT will be 13 percent higher. If there is a recession, then EBIT will be 22 percent lower. The company is considering a $195,000 debt issue with an interest rate of 8 percent. The proceeds will be used to repurchase shares of stock. There are currently 8,600 shares outstanding. The company has a tax rate of 21 percent, a market-to-book ratio of 1.0, and the stock price remains constant. Calculate earnings per share (EPS) under each of the three economic scenarios before any debt is issued.
a-1.
Calculate earnings per share (EPS) under each of the three economic scenarios before any debt is issued. (Do not round intermediate calculations and round your answers to 2 decimal places, e.g., 32.16.)
a-2. Calculate the percentage changes in EPS when the economy expands or enters a recession. (A negative answer should be indicated by a minus sign. Do not round intermediate calculations and enter your answers as a percent rounded to 2 decimal places, e.g., 32.16.)
b-1. Calculate earnings per share (EPS) under each of the three economic scenarios assuming the company goes through with recapitalization. (Do not round intermediate calculations and round your answers to 2 decimal places, e.g., 32.16.)
b-2. Given the recapitalization, calculate the percentage changes in EPS when the economy expands or enters a recession. (A negative answer should be indicated by a minus sign. Do not round intermediate calculations and enter your answers as a percent rounded to 2 decimal places, e.g., 32.16.)
EPS for recession is $3.7975, EPS for normal is $4.8686, EPS for expansion is $5.5015, and Percentage change in EPS for expansion is 13% and for recession is -22%, EPS under each of the three scenarios after recapitalization is 4360 and percentage change in EPS after the recapitalization is -31.17% and 18.42% for recession and expansion respectively.
A-1) Calculation of EPS under each scenario:
EBIT for expansion condition,
= EBIT × 113%
= $53,000 × 113%
= $59,890
EBIT for recession conditions,
= EBIT × 78%
= $53,000 × 78%
= $41,340
Tax = EBT × 21%
Net income = EBT - Taxes
EPS = Net income ÷ No. of shares
EPS for recession = $3.7975
EPS for normal = $4.8686
EPS for expansion = $5.5015
A-2) Calculation of Percentage change in EPS,
For Expansion = (Expansion EPS - Normal EPS) ÷ Normal EPS
= (5.05 - 4.86) ÷ 4.86
= 13%
For Recession = (Recession EPS - Recession EPS) ÷ Recession EPS
= (4.86 - 3.79) ÷ 4.86
= -22%
B-1) Calculation of EPS under each of the three scenarios after recapitalization,
Market to Book ratio (l) = Market value ÷ Book value
l = $395,600 ÷ Book Value
Book Value = $395,600
Stock Price = Book Value ÷ No. of outstanding shares
= $395600 ÷ 8,600
= 46
No. of shares repurchased = Debt ÷ Stock Price
= $195,000 ÷ 46
= 4240
No. of shares after repurchasing = No. of outstanding shares - No. of shares repurchased
= 8,600 - 4240
= 4360
B-2) Calculating percentage change in EPS after recapitalization,
For Recession = (Recession EPS - Recession EPS) ÷ Recession EPS
= (4.66 - 6.77) ÷ 6.77
= -31.17%
For Expansion = (Expansion EPS - Normal EPS) ÷ Normal EPS
= (8.02 - 6.77) ÷ 6.77
= 18.42%

b) What is the dosage in milligrams per hour, mg/hr?
c) How many milliliters per hour, ml/hr, should be administered?
The Dosage in milligrams per min, mg/min : 0.01mg / min
The Dosage in milligrams per hour, mg/hr : 0.6mg/hr
The dosage available in milliliters per hour, ml/hr: 6ml/hr
What is Dosage ?
A dosage is a predetermined amount of a drug, food, or pathogen that is administered as a single unit. The dose increases with the amount administered. In medicine, doses are most frequently calculated for substances.
Given,
Dose(mcg) = 10mcg/min
Dose available = 50mg
Volume of dose available = 500ml
a) The dosage in milligram per minute will be:
= 10mcg / 1000mcg
= 0.01mg / min
b) The dosage in milligrams per hour, mg/hr :
= 10mcg x 60min / 1000mcg
= 0.6mg/hr
c) By dosage formula we can write:
= OxV / A
Where,
O = Dose ordered
V = Volume of dose available
A = Dose available
So that we know,
Dose ordered (mg) = 0.6 mg
Volume of dose available (mL) = 500 mL
Dose available (mg) = 50 mg
= 0.6 x 500 / 50
= 6ml/hr
Hence,
The Dosage in milligrams per min, mg/min : 0.01mg / min
The dosage in milligrams per hour, mg/hr : 0.6mg/hr
The dosage available in milliliters per hour, ml/hr: 6ml/hr

The graph of a function f is given. Use the horizontal-line test to determine whether f is one-to-one.Is f one-to-one?
A function is called being one-to-one if, for every value of x, there is only one value of y and vice-versa.
If the graph of the function is given, a practical rule to determine if the function is one-to-one is to use the horizontal-line test.
This test is as follows: Imagine you have a horizontal line (maybe a ruler) and you can move it up and down the grid.
If your line touches the graph only once at every vertical position, then your function is one-to-one.
Now if we test our function drawn in blue, we can touch it only once as we move our line up and down, thus:
Is f one-to-one?
Yes

A probability density function, also known as the density of a continuous random variable, is a function used in probability theory whose value at any given sample (or point) in the sample space can be interpreted as giving a relative likelihood that the random variable's value would be close to that sample. While the absolute likelihood of a continuous random variable taking on any given value is 0, probability density (PDF) at two different samples can be used to infer, in any given draw of the random variable, how much more likely it would be that the random variable would be close to one sample compared to the other sample.
