The graph above shows the graphs of the cost (in green) and revenue (in blue) functions for a company that manufactures and sells small radios.
a) How many radios must be produced and sold to break even?
Answer:
b) What is the dollar amount coming in and going out if the company just breaks even?
Answer:
c) Use the formulas to write the company's profit function, (), from producing and selling radios.
(Notice in this problem, you must enter the entire function, not just the right hand side)
Answer:
d) How much profit will the company earn if it produces and sells 500 radios?
Answer:
Answers
The company must sell 400 radios to break even, i.e, when the revenue function and cost function is same.
The sum of the units sold times the price per unit is the revenue. Multiply the output level by the pricing function to get the revenue function.
The cost function is the total cost of production of the item which includes the cost of raw materials, labor, transport and establishment costs.
The cost function and the revenue function is given as:
Cost function is C(x) =5000 + 7.5x
And the revenue function is R(x) = 20x
a)In the break even point cost will be equal to revenue
so, C(x)=R(x)
or,5000+7.5x=20x
or,12.5x=5000
or, x=5000÷12.5
or, x=400
The number of radios produced to break even is 400.
(b)When the company breaks even then x=400
∴R(200)=200×20=8000
So the amount of money is dollars that is coming in or going out is given by 8000.
(c)We know that the profit=Revenue - cost
So the required profit function is given by:
p(x)=R(x)-C(x)
or, p(x)=20x-5000-7.5x
or,p(x)=12.5x-5000
(d)The company sells 500 radios
Therefore profit will be given by
p(500)=12.5×500-5000
or,p(500)=6250-5000
or, p(500)=1250
So on selling 500 radios the company will earn $1875.
Disclaimer: The revenue and cost function of the equation are
C(x) =5000 + 7.5x and R(x) = 20x .

Answers
The total mile Kaili ran during her training was 54.151 miles
Calculating total distanceFrom the question, we are to calculate the total miles Kaili ran during her training
From the given information,
" For the first five days of her training plan, she will need to walk 5.431 miles each day"
That is,
She ran 5 × 5.431 miles
5 × 5.431 miles = 27.155 miles
Also, from the information,
"For the next four days she will to increase her mileage and walk 6.749 per day"
That is,
She ran 4 × 6.749 miles
4 × 6.749 miles = 26.996 miles
Thus,
The total mile Kaili ran = 27.155 miles + 26.996 miles
The total mile Kaili ran = 54.151 miles
Hence, the total mile Kaili ran during her training was 54.151 miles

Consider the following problem.
One number is 3 less than 6 times a second number.
Their sum is 46. Find the numbers
If × represents the second number, which equation is
correct for solving this problem?
Answers
Step-by-step explanation:
y is the second number. This means we can define it as the following equations where x is the second number:
y=6x-3
y+x=46
we have a system of equations, let's move all x to the right side
y=6x-3
y=46-x
this means that 6x-3=46-x
6x+x=46+3
7x=49
x=7
now that we know x we can calculate the y through one of the equations above:

Line I has a Gamma connection time with parameters a = 3 and λ = 2 min-¹. Line II has
a Uniform(a, b) connection time with parameters a = 20 sec and b = 50 sec. Compute the
probability that it takes a randomly selected customer more than 30 seconds to connect to
the internet.
Answers
Using the uniform distribution, there is a 0.6667 = 66.67% probability that it takes a randomly selected customer more than 30 seconds to connect to the internet.
What is the uniform probability distribution?It is a distribution with two bounds, given by a and b, in which each possible outcome is equally as likely.
The probability of finding a value above x is:
[tex]P(X > x) = \frac{b - x}{b - a}[/tex]
For this problem, the connection time has parameters a = 20 sec and b = 50 sec, as stated in the problem.
The probability that it takes a randomly selected customer more than 30 seconds to connect to is P(X > 30).
Hence, applying the formula, with the bounds, we have that:
P(X > 30) = (50 - 30)/(50 - 20) = 2/3 = 0.6667.
The measure above is the desired probability.

What is a linear equation ?
There are only one or two variables in a linear equation. No variable can be multiplied by a number larger than one or used as the denominator of a fraction in a linear equation. All of the points fall on the same line when you identify the values that together make a linear equation true and plot those values on a coordinate grid.let x be the salary of individual with bachelor degree
Then the average salary of individual with Masters degree is:
(2x-40000)
the combined of two salaries is 130000:
x+(2x-40000)=130000
3x-40000=130000
3x=130000+40000
x=170000/3
x = 56,666.66
x= 56,666.6 dollars ( the average salary of bachelor degree)
the average salary of Masters degree = 2x - 40000

Z-scores can be placed on a normal distribution curve. Z-scores range from -3 standard deviations (leftmost part of normal distribution curve) to +3 standard deviations (rightmost part of normal distribution curve).

Answers
The inequality represents the number of rides that Connor can afford is 1.50x+5≤22 and he can ride 11 rides
The amount Connor had when he went to the fair = $22
The cost of a hotdog and coke = $5
The cost of each ride = $1.50
Consider then number of rides he ride as x
Then, the equation of the inequality is
1.50x+5≤ 22
Solve the inequality
1.50x+5≤ 22
1.50x ≤ 17
x ≤ 11.33

The quotient of x² − 16/ x − 4 is x + 4.
Now, We have compute each quotient as;
The quotient of x³ - 64/x - 4 is;
[tex]\frac{x^{3} - 64}{x-4} = \frac{x^{3} - 4^{3} }{x-4} = \frac{(x-4) (x^{2} +4x+16)}{(x-4)} = (x^{2} +4x+16)[/tex]

And, The quotient of x⁴ − 256/x − 4 is;
[tex]\frac{x^4-4^4}{x-4} = \frac{((x^2)^2-(4^2)^2)}{(x-4)} = \frac{(x^{2} -4^4) (x^{2} + 4^2)}{(x-4)} = \frac{(x-4)(x+4)(x^{2} +4^2)}{(x-4)} = (x+4)(x^{2} + 16)[/tex]
[tex](x+4)(x^{2} + 16) = x^{3} + 4x^{2} +16x + 64[/tex]
