Rounding off to the nearest tenths = the value should be written correctly to one decimal place. The tenth place value in a decimal number is the first number which comes first after the decimal point. For this, we need to observe the hundredth number (the number which comes second after the decimal point). If this number is greater than or equal to 5, we add 1 to the tenth value. If it is less than 5, we leave the tenth place value as it is, and remove all the numbers present after this number.

Finding the Equation of a Line Given Two Points:

Most people when asked, “What is the equation of a line?”, will answer, “y = mx + b”. This is the

equation of a line in what is called slope-intercept form where “m” is the slope and “b” is the y-

intercept. So, how do you find the equation of a line? There are several different ways that you can find

the equation of a line. I find the equation of a line everytime by following the same three steps:

Step 1: Find the slope of the line.

Step 2: Use the slope to find the y-intercept.

Step 3: Use steps 1 and 2 to write the answer.

I will explain these steps by looking a several examples. Please understand that there are often several

different ways to complete each math problem, but I have found through the years that students are most

successful when the do problems the same way each and every time they attempt the problem. If you

know a different way to find the answer that is great, but I am going to show how to do the problem one

way and use the same technique everytime I see this problem.

Example 1: Find the equation of the line passing through the points (–1, –2) and (2, 7).

Step 1: Find the slope of the line.

To find the slope of the line passing through these two points we need to use the slope

formula:

( )

( )

So the slope of the slope of the line passing through these two points is 3.

Step 2: Use the slope to find the y-intercept.

Now that we know the slope of the line is 3 we can plug the slope into the equation and

we get:

y = 3x + b

Next choose one of the two point to plug in for the values of x and y. It does not matter

which one of the two points you choose because you should get the same answer in either

case. I generally just choose the first point listed so I don’t have to worry about which

one I should choose.

(–1, –2) → –2 = 3(–1) + b Multiply to simplify the problem.

–2 = –3 + b Solve for b and you will have the y-intercept. b=1

Step 3: Write the answer.

Using the slope of 3 and the y-intercept of 1, the answer is:

y = 3x + 1

The simplified form of the expression 2x^2 - 3x - 2 remains as 2x^2 - 3x - 2.

To simplify the expression 8x - 2x - x^2, we can combine like terms by adding or subtracting coefficients.

8x - 2x - x^2

First, let's combine the x terms:

(8x - 2x) - x^2

This simplifies to:

6x - x^2

Therefore, the simplified form of the expression 8x - 2x - x^2 is 6x - x^2.

Now, let's simplify the expression 2x^2 - 3x - 2:

The expression is already in simplified form, and no further simplification is possible.

Therefore, the simplified form of the expression 2x^2 - 3x - 2 remains as 2x^2 - 3x - 2.

Using the normal distribution, it is found that:

a) The 10th percentile for incubation times is of: 18.72 days.

b) The incubation times that make up the middle 95​% are of: Between 18.04 and 21.96 days.

The z-score of a measure X of a variable that has mean symbolized by \(\mu\) and standard deviation symbolized by \(\sigma\) is obtained by the rule presented as follows:

\(Z = \frac{X - \mu}{\sigma}\)

The mean and the standard deviation for the incubation times are presented as follows:

\(\mu = 20, \sigma = 1\)

The 10th percentile for the distribution is X when Z = -1.28, which is the value of Z with a p-value of 0.1, hence:

-1.28 = (X - 20)/1

X - 20 = -1.28

X = -1.28 + 20

Z = 18.72 days.

Considering the symmetry of the normal distribution, the bounds of the middle 95% of values are given as follows:

Hence the lower bound is:

-1.96 = (X - 20)/1

X - 20 = -1.96

X = -1.96 + 20

Z = 18.04 days.

The upper bound is:

1.96 = (X - 20)/1

X - 20 = 1.96

X = 1.96 + 20

Z = 21.96 days.

Answer:

1 full physical and 33 routine visits per day to maximize income for the day.

Maximum income is $2080.

Step-by-step explanation:

The doctor has 9 hours per day which equals to 9 x 60 = 540 minutes

If there are 10 physicals per day, the maximum minutes will be 45 x 10 = 450 minutes.

so the time left for routine office visits will be 540 - 450 = 90 minutes

then the number of routine office visits will be 90 / 15 = 6

Her income will be ($100 x 10) + ($60 x 6) = 1000 + 360 = $1360

If there is 1 physical per day, then the time will be 45 x 1 = 45 minutes

so time left for routine office visits will be 540 - 45 = 495 minutes

then the number of routine office visits will be 495 / 15 = 33

Her income will be ($100 x 1) + ($60 x 33) = 100 + 1980 = $2080

If there are 2 physicals per day, then the time will be 45 x 2 = 90 minutes

so time left for routine office visits will be 540 - 90 = 450 minutes

then the number of routine office visits will be 450 / 15 = 30

Her income will be ($100 x 2) + ($60 x 30) = 200 + 1800 = $2000

Answer:

Step-by-step explanation:

You want to maximize the doctor's income when she makes $60 for a 15-minute routine visit and $100 for a 45-minute physical. She can work 9 hours per day.

For a routine visit, the doctor is charging $60 for 15 minutes, or $4 per minute.

For a physical, the doctor is charging $100 for 45 minutes, or $2.22 per minute.

Clearly, the doctor earns income faster by spending her time doing routine office visits. There appears to be no limit on the number of those she can do.

Working 9 hours at $4 per minute, the doctor earns ...

  (9 h/day)(60 min/h)($4/min) = $2160/day

The number of routine visits in a day will be ...

  (9 h/day)(60 min/h)/(15 min/visit) = (9·60/15) visits/day = 36 visits/day

The doctor's maximum income is $2160 per day, making 36 routine office visits per day.

__

Additional comment

Each physical will reduce the doctor's income by $80. (In that 45 minutes, she could have done 3 routine visits, for a revenue of 3·60 = 180, instead of the physical for a revenue of 100.)

This is an example of a sample survey or a sampling method.

Sampling techniques in a statistical study refer to how participants are chosen from the population to participate in the study. If a sample isn't chosen at random, it will likely be skewed in some way, and the results might not be generalizable.

In the given scenario, you are conducting a sample survey to determine the proportion of each color of Peanut Butter M&Ms. A sample survey is a method used to collect data from a subset of a larger population in order to make inferences about the entire population.

Instead of counting every single Peanut Butter M&M in existence, which would be impractical and time-consuming, you decide to take a smaller representative sample. You purchase 10 packages of Peanut Butter M&Ms, each weighing 1.69 ounces, and count the number of M&Ms of each color in those packages.

By analyzing the data collected from this sample, you can estimate the proportion of each color of Peanut Butter M&Ms in the larger population. This approach is more feasible and provides a reasonable approximation of the overall distribution of colors without having to examine every individual item.

For the differential equation y′ + 2xy^2 = 0, we will substitute the given function y = f(x) into the equation and check if it satisfies the equation. Taking the derivative of y with respect to x, we have y′ = f'(x). Substituting these into the equation, we get f'(x) + 2xf(x)^2 = 0. If this equation holds true for all x in the domain, then the function y = f(x) is a solution to the differential equation.

For the differential equation x^2y′′ + xy′ − y = ln(x), we will substitute the given function y = f(x) into the equation and check if it satisfies the equation. Taking the first and second derivatives of y with respect to x, we have y′ = f'(x) and y′′ = f''(x). Substituting these into the equation, we get x^2f''(x) + xf'(x) - f(x) = ln(x). If this equation holds true for all x in the domain, then the function y = f(x) is a solution to the differential equation.

The digit that occurs the least frequently in the numbers between 1 and 1,000 is 9, which appears only 271 times.

To answer this question, we need to analyze the numbers between 1 and 1,000 and determine which digit occurs the least frequently. We can start by looking at each individual digit (0-9) and counting how many times it appears in each of the numbers in this range.
For example, the digit 0 appears 192 times in this range, while the digit 1 appears 301 times. We can continue this process for all of the digits and find that the digit that occurs the least frequently is 9, which appears only 271 times.
We can also note that this is not surprising since 9 is the largest single-digit number, and thus, it is less likely to appear in numbers between 1 and 1,000. Additionally, we can observe that the digits 0-8 all appear relatively evenly throughout this range, with each digit appearing between 271-305 times.
In conclusion, the digit that occurs the least frequently in the numbers between 1 and 1,000 is 9, which appears only 271 times.

The box should have base 52 cm by 52 cm and height 26 cm.

What is volume?

A three-dimensional space's occupied volume is measured. It is frequently expressed as a numerical value using SI-derived units, other imperial units, or US customary units. Volume definition and length definition are connected.

The Volume of a box with a square base x by x cm and height h cm is

\(V = x^2h\)

Since the surface area directly affects the amount of material used, we can reduce the amount of material by reducing the surface area.

The surface area of the box described is  \(A = x^2 + 4xh\)

We need A as a function of x alone, so we'll use the fact that

\(V = x^2h= 70304 cm^3\)

⇒ \(h = \frac{70304}{x^2}\)

So, the area becomes,

\(A = x^2+4x(\frac{70304}{x^2})\\ A = x^2 + \frac{281216}{x}\)

We want to minimize A, so

\(A' = 2x - \frac{281216}{x^2} =0\\\frac{2x^3-281216}{x^2}=0\\ {2x^3-281216} = 0\\x^3 - 140608=0\\x^3 = 140608\\x = 52\)

The second derivative test verifies that A has a minimum at this critical number:

\(A'' = 2+\frac{562432}{x^3}\)  which is positive at x = 52.

Now,

\(h = \frac{70304}{x^2}= \frac{70304}{(52)^2}=26\)

Step-by-step explanation:

Take the shaded figure as a full larger rectangle minus the rectangular part which is not shaded.

Area of the full larger rectangle:

Area = length × width

Length = |12 - 2| = 10 units

Width = |8 - 1| = 7 units

Area = 10 × 7 = 70 units²

Area of the unshaded small rectangle:

Length = |10 - 4| = 6 units

Width = |3 - 1| = 2 units

Area = 6 × 2 = 12 units²

Area of the shaded figure = 70 - 12 = 58 square units

The percentage of 322 out of 450 using the percentage formula was found out to be approximately 71.56%.

To find the percentage of 322 out of 450, we can use the following formula:

where, "part" is the value we want to express as a percentage (in this case, 322), "whole" is the total value (in this case, 450), and "x" means "multiply".

Using the formula mentioned above, we get:

percentage = (322/450) x 100

percentage = 0.7156 x 100

percentage = 71.56%

Therefore, percentage of 322 out of 450 is approximately 71.56%.
