The value of x on the number line is 24 and - 40
A number line in elementary mathematics is a representation of a graduated straight line that acts as an abstraction for real numbers, represented by the letter R. It is assumed that every point on a number line corresponds to a real number, and that every real number corresponds to a point.
When seen as a geometric space, namely the one-dimensional Euclidean space, the number line, also known as a real line in advanced mathematics, is technically defined as the set R of all real numbers. It can be conceptualized as a linear continuum, metric space, topological space, vector space (or affine space), measure space, or topological space.
The given equation is

the volume of water is usually distributed with a mean of 62ml and standard deviation of 40ml. What is the probability that the volume will be greater than 90ml?
The probability of the volume of water being over 90 ml is 24.10%.
What exactly is the standard normal distribution?A symmetric probability distribution only with equal mean, mean, as well as mode values is known as a standard normal distribution.A statistical table as well as computer software is used to estimate the likelihood of a standard normal distribution.For the given question;
The mean of the sample is; μ = 62 ml.
The standard distribution is; σ = 40 ml.
The probability of the values must lie more than 90 ml.
Thus,
P(x > 90) = P[ (x - μ)/ σ ]
Substitute the values;
P(x > 90) = 1 - P[ (90 - 62)/ 40]
P(x > 90) = 1 - P[0.7]
P(x > 90) = 1 - 0.758
P(x > 90) = 0.2410
P(x > 90) = 24.10%
Therefore, the probability that the the volume of water will be greater than 90 ml is 24.10%.

When the admission price for a baseball game was $5 per ticket, 35,000 tickets were sold. When the price was raised to $6, only 30,000 tickets were sold. Assume that the demand function is linear and that the variable and fixed costs for the ball park owners are $0.10 and $95,000 respectively.
(a)
Find the profit P as a function of x, the number of tickets sold
The profit function is P(x) = ( - x² / 5000 ) + 11.9x - 95000.
35,000 baseball game tickets were sold at $5 per ticket.
When the price is raised to $6, then 30,000 tickets were sold.
The variable and fixed costs for the ballpark owners are $0.10 and $95,000 respectively.
Let's say x is the number of tickets sold, and P is the profit.
Then,
P = ax + b
At P = 5,
5 = (35000)a + b ---------(1)
At P = 6,
6 = (30000)a + b --------(2)
Subtracting (2) from (1),
5 - 6 = (35000)a + b - (30000)a - b
- 1 = 5000(a)
a = ( - 1/5000)
So if a = ( - 1/5000),
Then,
5 = (35000)a + b
5 = (35000)( - 1 / 5000 ) + b
5 = - 7 + b
b = 12
Therefore,
P(x) = ( - x /5000) + 12
Now, the profit function is:
Profit = Revenue - Costs
P(x) = R(x) - C(x)
Now, R(x) = xp(x)
R(x) = x[ ( - x/5000) + 12]
R(x) = ( - x² / 5000 ) + 12x
The fixed cost is F(x) = $95000
Hence, the costs will be:
C(x) = 95000 + (0.10)x
Therefore the profit function is:
P(x) = R(x) - C(x)
P(x) = ( - x² / 5000 ) + 12x - 95000 - (0.10)x
P(x) = ( - x² / 5000 ) + 11.9x - 95000

Step-by-step explanation:
1) the slope-interception view of the required tangent line is
y=slope*x+interception;
2) y'=3x²-3;
3) slope=y'(3), then slope=3*3²-3=24;
4) the required equation of tangent line has the form

c. Make a table and identify the range of the function.
a) "how many quarters you have is a function of how many times you paid for the parking meter."
b) y = 10 - x
domain: {0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10}
range: {0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10}

y: 10, 9, 8, 7, 6, 5, 4, 3, 2, 1, 0
How to complete the blanks?Here we know that you have a total of 10 quarters, and the parking meter costs 1 quarter.
Then, each time if we define two variables:
y = how many quarters you have.
x = how many times you paid for the parking meter.
We can write:
"y is a function of x"
Or:
"how many quarters you have is a function of how many times you paid for the parking meter."
b) The rule is really simple, it would be a linear relation:
y = 10 - x
The domain (the set of possible values of x) is:
{0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10}
You can't use less than 0 quarters and you can't use more than 10.
c) The range is also:
{0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10}
Which represents the possible numbers of quarters that you can have.

The amount of money Robert has left given the amount he started with and after deducting tax is approximately $7.34
How much does Robert have left after deducting tax?Tax can be defined as the compulsory levy paid by citizens of a particular country on their income, goods and be services.
Amount Robert started with = $40Amount Robert spent before tax = $30.45Tax rate = 7.25%Amount of tax = Tax rate × Amount Robert spent before tax

consider the line y=9x-8 find the equation that is perpendicular to this line and passes through the point -8,3
The equation of line is y=-9x-69.
To solve this problem we need to know the concept of slope of line and equation of straight line.
Writing the standard form of line is in the form of y= mx+ c where m is the slope of line.
And we also know that the product of slope of a line perpendicular to the line is equal to -1.
Let us assume that the slope of required line is m'
So, m' × 9 = -1

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.”

TC = Total Cost
AC = Average Cost
(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.
