Profit is determined using the equation Profit = Selling Price - Cost Price. The final price after discount is $612.
Following this, the formula for calculating profit percentage is: profit percentage = (profit/cost price) x 100.
What is the loss percent formula?
The firm is considered to be losing money if a product's cost price is higher than its selling price; conversely, if the product's cost price is lower than its selling price, a profit might be made. Loss% is equal to Loss/CP multiplied by 100.
Profit is calculated as cost less selling price. Similar to this, the cost price is higher than the targeted selling price when a loss occurs. A profit percentage is computed by dividing the cost price by 100. 100 divided by the cost price is the loss percentage.
Determine the net profit and loss from a company's operations over the course of an accounting period with the help of the profit and loss account, also referred to as the income statement. The trading account's gross profit or loss is transferred to this account.
Given,
the cost price = $500
Selling price = 70% increase in import price
70 / 100 × $500 = $ 350
Selling price = $350 + $500
Selling price = $850
Selling price after 20% discount = 20% of $850
⇒ 0.2 × 850 = 170
⇒ Selling price after 20% discount = $850 - $170 = $680
Selling price after discount 10% = 0.10 × $680 = $68
Selling price after discount 10% = $680 - $68 = $612

Among recent graduates of mathematics departments, half intend to teach high school. A random sample of size 2 is to be selected from the population of recent graduates. a. If mathematics departments had only four recent graduates total, what is the chance that the sample will consist of two graduates who intend to teach high school? b. If mathematics departments had 10 million recent graduates, what is the chance that the sample will consist of two graduates who intend to teach high school? c. Are the selections technically independent in part a? Are they technically independent in part b? In which part can you assume independence anyway? Why?
In part a, since the population mean is small, selections are independent and can be assumed to be so. In part b, the population size is too large for selections to be independent, so independence can not be assumed.
a. If mathematics departments had only four recent graduates total, the chance that the sample will consist of two graduates who intend to teach high school is
0.5 * 0.5
= 0.25.
b. If mathematics departments had 10 million recent graduates, the chance that the sample will consist of two graduates who intend to teach high school is

A student decides to finance a used car over a 5-yr (60-month) period. After making a down
payment of $2000, the remaining cost of the car including tax and interest is $14,820. The
amount owed y = A(t) (in $) is given by A(t) = 14,820-247t, where t is the number of
months after purchase and 0 ≤t≤ 60. Determine the t-intercept and y-intercept and interpret
their meanings in context.
Answer:The t-intercept of a function is the point at which the function crosses the t-axis. To find the t-intercept of the function A(t) = 14,820 - 247t, we need to find the value of t when A(t) = 0. Setting A(t) = 0 and solving for t, we get:
14,820 - 247t = 0
t = (14820/247)
The t-intercept of the function is 60 months, which means that after 60 months (or 5 years) the amount owed on the car will be $0.
The y-interval of a function is the point at which the function crosses the y-axis. To find the y-intercept of the function A(t) = 14,820 - 247t, we need to find the value of A(t) when t = 0.
At t = 0, A(t) = 14,820 - 247(0) = 14,820.
The y-intercept of the function is $14,820 which means that before making the first payment, the cost of the car including tax and interest is $14,820.

The result of the convolution integral is the same as the solution obtained in part (a).
a. Solving the ODE with y(0) = 0 using integrating factors,
multiplying both sides of the equation by e^4t, we get
e^4t y' + 4e^4t y = 4e^-te^4t
Integrating both sides,

If ‘a’ varies jointly with ‘b’ and ‘c’, and inversely as the square of ‘d’, how would ‘a’ be affected if ‘b’ is tripled and both ‘c’ and ‘d’ are doubled.
When two or more variables vary jointly, their product is always constant. In this case, if 'a' varies jointly with 'b' and 'c' it means that their product is always constant, so abc = k, where k is a constant value.
When a variable 'a' varies inversely as the square of another variable 'd', it means that a*1/d^2 = k, where k is a constant value.
So, if 'b' is tripled, 'c' is doubled and 'd' is doubled, we can see the effect on 'a' by substituting the new values into the equations.
abc = k => a3b2c = k
a1/d^2 = k => a1/(2d)^2 = k
So the effect on 'a' if 'b' is tripled, 'c' is doubled, and 'd' is doubled is that it will be divided by 4.
a3b2c = a1/(2d)^2 => a = k / (3b2c*(2d)^2) = (k/(12bcd^2))
So a = k/(12bcd^2) = a/4.
Therefore, the value of 'a' is decreased by a factor of 4.

12. Hydrology A reservoir has a capacity of 9000 cu ft. How long will it take
to fill the reservoir at the rate of 250 gallons per minute?
It will take approximately 270.28 minutes, or 4 hours and 30.28 minutes, to fill the reservoir at a rate of 250 gallons per minute.
How to calculate the time it takes to fill a reservoir?we can use the formula:
time = volume ÷ flow rate
where volume is the capacity of the reservoir in cubic feet and flow rate is the rate at which the reservoir is filled in cubic feet per minute.
Since the capacity of the reservoir is given in cubic feet and the flow rate is given in gallons per minute, we need to convert the flow rate to cubic feet per minute. One gallon is equal to 0.133681 cubic feet, so:
250 gallons/minute x 0.133681 cubic feet/gallon = 33.342 cubic feet/minute
So the flow rate in cubic feet per minute is 33.342. Now we can calculate the time it takes to fill the reservoir:
time = 9000 cubic feet ÷ 33.342 cubic feet/minute = 270.28 minutes
So it will take approximately 270.28 minutes, or 4 hours and 30.28 minutes, to fill the reservoir at a rate of 250 gallons per minute.

the distance between (4,-2) and (0,4) is √(52) or approximately 7.2 units.
Step-by-step explanation:
To find the distance between two points in a Cartesian coordinate plane, we can use the distance formula:
distance = √((x2-x1)² + (y2-y1)²)
In this case, the two points are (4,-2) and (0,4). So,
x1 = 4, y1 = -2 and x2 = 0, y2 = 4
By substituting these values in the distance formula, we get:
distance = √((0-4)² + (4-(-2))²)
distance = √((-4)² + 6²)
distance = √(16 + 36)
distance = √(52)
So the distance between (4,-2) and (0,4) is √(52) or approximately 7.2 units.
Out of 300 people sampled, 60 preferred Candidate A. Based on this, estimate what proportion of the voting population ( p ) prefers Candidate A. Use a 95% confidence level, and give your answers as decimals, to three places.
___ < p < ___
At 95% confidence level, the proportion will be between .0.19912815 and 0.200086, when you have a mean of 0.2 and a standard error of 0.00053.
How do you calculate population proportion?
P′ is equal to x / n, where x is the total number of successes and n is the sample size. As a point estimate for the genuine population proportion, the variable p′ represents the sample proportion.
FPC = (N-n)/(N-1), where Z/2 is the critical value of the Normal distribution at /2, p is the sample proportion, n is the sample size, and N is the size of the population (for example, at a confidence level of 95%, is 0.05 and the critical value is 1.96).
A portion of a population that possesses a certain characteristic, given as a percentage, fraction, or decimal of the entire population. The population percentage for a finite population is equal to the population's size divided by the proportion of its members who possess a given attribute.
Given data :
p = 60 / 300 = 0.2
q = 1 - p = 0.8
mean proportion = p = .2
standard error = sqrt(p * (1-p / 300) = sqrt(0.2 * 0.8/ 300) =0.00053333333
critical z-score at 95% confidence level is plus or minus 1.645.
use the z-score formula to find the critical raw score.
for the low side, z = (x - m) / s becomes:
-1.645 = (x - 0.2) / 0.00053
solve for x to get:
x = -1.645 * 0.00053 + 0.2 = 0.19912815
for the high side, z = (x - m) / s becomes:
1.645 = (x - 0.2) / 0.00053
solve for x to get:
x = 1.645 * 0.00053 + 0.2 = 0.200086125
At 95% confidence level, your proportion will be between .0.19912815 and 0.200086, when you have a mean of 0.2 and a standard error of 0.00053.

when the fraction 1/70000000 is written as a decimal, which digit occurs i the 2023 place after the decimal point
The decimal representation of 1/70000000 is 0.0000000142857142857....
In math, what is a fraction?
An element of a whole is a fraction. The number is represented mathematically as a quotient, where the numerator and denominator are split. Both are integers in a simple fraction. A fraction appears in the numerator or denominator of a complex fraction. The numerator of a proper fraction is less than the denominator.
To find the digit that occurs in the 2023rd place after the decimal point, we can use long division to divide 1 by 70000000 and track the remainders.
Since the decimal representation of 1/70000000 is repeating every 6 digits, we can find the digit at the 2023rd place by taking the remainder when 2023 is divided by 6.
2023 % 6 = 1
So the digit in the 2023 place is the first digit after the repeating decimal, which is 4.
Therefore the digit in the 2023rd place after the decimal point is 4.

The logarithmic functions, f(x) and g(x), are shown on the graph.
What is the equation that represents g(x)? Explain your reasoning.
The image of the function after the translation is g(x) = log(x + 1) + 4
What is graph?In mathematics, the graph of a function f is the set of ordered pairs, where {\displaystyle f(x)=y.} In the common case where x and f(x) are real numbers, these pairs are Cartesian coordinates of points in two-dimensional space and thus form a subset of this plane.
here, we have,
f(x)=logx
How to determine the equation of g(x)?
From the graph, the given parameters are:
f(x) = log(x)
From the graph, we can see that:
The graph of f(x) is translated left by 1 unit
The graph of f(x) is translated up by 4 units
This transformation is given as
g(x) = f(x + 1) + 4
Mathematically, this transformation can be represented as
(x, y) = (x + 1, y + 4)
When represented as a function, we have
g(x) = f(x + 1) + 4
Substitute the equation f(x) = log(x)
f(x + 1) = log(x + 1) + 4
So, we have the following equation
g(x) = log(x + 1) + 4
Hence, the equation of g(x) is g(x) = log(x + 1) + 4

What is the Probability.
The value of the conditional Probability is P(A|B) is 1/3.
What is probability ?The area of mathematics known as probability deals with numerical representations of the likelihood that an event will occur or that a statement is true. An event's probability is a number between 0 and 1, where, broadly speaking, 0 denotes the event's impossibility and 1 denotes certainty.
The main distinction between a probability and a conditional probability is that a probability is the likelihood of an event, such as A, occurring, whereas a conditional probability assumes that another event, such as B, has already happened in order to define the probability of an event, such as in the conditional probability of A given B.
Conditional probability is the likelihood that any event A will occur in the presence of another event B that is related to A. P(A|B) illustrates it.
By, Conditional Probability :
P (A∩B) =P (A∩B') - P(B)= 4/9 - 1/3 = 1/9
P(A|B) = P (A∩B)/ P(B)
= (1/9)/(1/3) = 1/3
