Fro the one to one functions g and h defined, the value of :
g⁻¹(6) = 2
h⁻¹(x) = 7x + 8
(h⁻¹ o h)(1) = 1
Given one to one functions h and g.
We have that,
g(2) = 6
So, g⁻¹(6) = 2
We have,
y = (x - 8) / 7
Switch x and y.
x = (y - 8) / 7
7x = y - 8
y = 7x + 8
So, h⁻¹(x) = 7x + 8
(h⁻¹ o h) (x) = h⁻¹ (h(x))
= h⁻¹ ((x - 8) / 7)
= 7 ((x - 8) / 7)) + 8
= x - 8 + 8
= x
(h⁻¹ o h) (1) = 1
Hence the functions are found.

Maureen Webster, who is running for mayor in a city, claims that she is favored by 53% of all eligible voters of that city. Assume that this claim is true. What is the probability that in a random sample of 400 registered voters taken from this city, less than 49% will favor Maureen Webster?
Answers
The probability that a random sample of 400 registered voters from this town will have a Maureen Webster under the age of 49 is about 0.0951, or about 9.51%.
What does probability mean?Probability is simply how likely something is to happen. When we are uncertain about the outcome of an event, we can talk about the probability of certain outcomes—how likely they are.
We can use the binomial normal approximation to solve this problem because we have a large sample (400) and the probability (p) of preferring Maureen Webster is not too close to 0 or 1. First, we need to find the mean and standard deviation of the sample proportion, which is given by:
mean = p = 0.53
standard deviation = square (p*(1-p)/n) = square (0.53*0.47/400) = 0.0305
Next, we need to find the z-score corresponding to the sample proportion of 0.49 (which is the "less than 49 percent" threshold). It is given by:
z = (x - mean) / standard deviation = (0.49 - 0.53) / 0.0305 = -1.31
We can now use a standard normal distribution table or calculator to determine the probability that the standard normal variable is less than -1.31. This probability is approximately 0.0951.
Therefore, we can use the binomial normal approximation to solve this problem because we have a large sample (400) and the probability (p) of preferring Maureen Webster is not too close to 0 or 1.

C. How much cash flow is lost due to the reduced depreciation from $48,000 to $16,000?
Cash flow lost?
Answers
A. The cash flow would be $91,400 if the depreciation were $48,000.
B. The cash flow would be $81,800 if the depreciation were $16,000.
C. The lost cash flow due to the reduced depreciation from $48,000 to $16,000 is $9,600.
How cash flow interacts with depreciation:A) Depreciation of $48,000:Earnings before depreciation and taxes = $110,000
Depreciation = $48,000
Earnings before taxes = $62,000 ($110,000 - $48,000)
Taxes (30%) = $18,600 ($62,000 x 30%)
Earnings after taxes = $43,400 ($62,000 - $18,600)
Depreciation $48,000
Cash flow = $91,400 ($43,400 + $48,000)
B) Depreciation of $16,000:Earnings before depreciation and taxes = $110,000
Depreciation = $16,000
Earnings before taxes = $94,000 ($110,000 - $16,000)
Taxes (30%) = $28,200 ($94,000 x 30%)
Earnings after taxes = $65,800 ($94,000 - $28,200)
Depreciation $16,000
Cash flow = $81,800 ($65,800 + $16,000)
C) Lost Cash Flow:Cash flow at $48,000 depreciation = $91,400
Cash flow at $16,000 depreciation = $81,800
Lost cash flow = $9,600 ($91,400 - $81,800)
Thus, we can learn that reduced depreciation increases the tax liability, thereby reducing the cash flow.

A right rectangular prism has a length of 15 cm width of 10 cm and a height of 5 cm savanna claims that doubling the length width and height of the prism will double its surface area is Savannah, correct?
Answers
No, Savannah is incorrect. Doubling the length, width, and height of a right rectangular prism will not double its surface area.
What is surface area?Surface area is the total area of an object's exposed faces, including any external surface area. It is a measure of the size of a surface and is usually expressed in square units such as square meters or square centimeters. Surface area is a two-dimensional measurement, since it only takes into account the area of a surface, and not its thickness or volume.
The surface area of a right rectangular prism is calculated by multiplying the length by the width and then multiplying that number by two and adding the two products together.
For example, the surface area of a right rectangular prism with a length of 15 cm, a width of 10 cm, and a height of 5 cm is calculated as follows:
Surface area = (15 cm * 10 cm) + (15 cm * 5 cm) = 150 cm2 + 75 cm2 = 225 cm2
Doubling the length, width, and height of this right rectangular prism would give us a prism with a length of 30 cm, a width of 20 cm, and a height of 10 cm. The surface area of this new prism would be calculated as follows:
Surface area = (30 cm * 20 cm) + (30 cm * 10 cm) = 600 cm2 + 300 cm2 = 900 cm2
As you can see, doubling the length, width, and height of the right rectangular prism does not double its surface area - the surface area has increased by four times (900 cm2/225 cm2 = 4).
In conclusion, doubling the length, width, and height of a right rectangular prism does not double its surface area; rather, it increases the surface area by a factor of four.

All four of these inequalities are true. Use them to find the single whole-number value of g. Use that whole number to unlock the door. Your answer g>0 g≤100 4 5.5 is greater than g?
Answers
To find the value of g, we need to use the inequalities given. Since g>0 and g≤100, we know that g must be a whole number between 1 and 100.
The other two inequalities are not useful for finding g, so we can ignore them.
We don't know what value of g is, but we do know that 5.5 is greater than g. This means that g must be less than 5.5.
The only whole number between 1 and 100 that is less than 5.5 is 5.

Write the equation of the line that passes through the points (−9,1) and (−6,−1). Put your answer in fully simplified point-slope form, unless it is a vertical or horizontal line.
Answers
slope = (y2 - y1) / (x2 - x1)
where (x1, y1) = (-9, 1) and (x2, y2) = (-6, -1)
slope = (-1 - 1) / (-6 - (-9))
slope = (-2) / 3
slope = -2/3
Now, we can use the point-slope form of the equation of a line to find the equation:
y - y1 = m(x - x1)
where m is the slope and (x1, y1) is one of the given points.
Using the point (-9, 1), we get:
y - 1 = (-2/3)(x - (-9))
y - 1 = (-2/3)(x + 9)
This is the equation of the line in point-slope form. We can simplify it further by distributing the -2/3:
y - 1 = (-2/3)x - 6
y = (-2/3)x - 5
So the equation of the line that passes through the points (-9, 1) and (-6, -1) is y = (-2/3)x - 5.
if the distance between the line x+y-5 and 3x+3y-k=0 is √18, find the value of k.
Answers
Therefore, the value of k could be either 6 or 24 if the distance between the line x+y-5 and 3x+3y-k=0 is √18.
What is equation?An equation is a statement that two mathematical expressions are equal. It contains an equal sign and can include variables, constants, and mathematical operations such as addition, subtraction, multiplication, and division. Equations can be used to solve problems, find unknown values, and model real-world situations.
Here,
To find the distance between the line x+y-5 and 3x+3y-k=0, we need to find the perpendicular distance between them.
The line x+y-5 can be written in slope-intercept form as y = -x + 5, and its slope is -1.
The line 3x+3y-k=0 can be rewritten as y = -x + k/3, and its slope is also -1.
Since the slopes of the two lines are the same, they are parallel. Therefore, the perpendicular distance between them is the distance between any point on one line and the other line.
Let's choose a point on the line x+y-5. We can choose (1,4) since it lies on the line. The distance between this point and the line 3x+3y-k=0 is:
|3(1) + 3(4) - k|/√(3²+3²)
Simplifying this, we get:
|15 - k|/3√2 = √18
Multiplying both sides by 3√2, we get:
|15 - k| = 3√2 * √18
= 9
This gives us two possible values for k:
15 - k = 9, which gives k = 6
or
k - 15 = 9, which gives k = 24

How to find the equation of a line?The equation of a line can be represented in different form such as slope intercept form.
The equation of a line in slope intercept form can be represented as follows:
y = mx + b
where
m = slopeb = y-interceptHence, let's find the equation of a line passing through (3, -2) and is parallel to the line shown.
Parallel line have the same slope.
Hence,
m = -4 + 1 / 1 - 2
m = -3 / -1
m = 3
Therefore,
y = 3x + b
-2 = 3(3) + b
b = -2 - 9
b = -11
The equation is y = 3x - 11
Hence, let's find the equation of a line passing through (3, -2) and is perpendicular to the line shown.
The slopes of perpendicular lines are negative reciprocals of one another.
hence,
m = - 1 / 3

Find the exact value of x.
Answers
Applying the Pythagorean theorem, the exact values of x are:
1. x = 13 2. x = 4 3. x = 6 4. x = 8 5. x = 15 6. x = √7
How to Find the Exact Value of x Using the Pythagorean Theorem?If a and b are smaller sides (legs) of a right triangle, and c is the longest side (hypotenuse), the Pythagorean theorem states that:
c = √(a² + b²).
Apply the Pythagorean theorem to find the exact value of x:
1. x = √(12² + 5²)
x = 13
2. x = √(5² - 3²)
x = 4
3. x = √(10² - 8²)
x = 6
4. x = √(17² - 15²)
x = 8
5. x = √(12² + 9²)
x = 15
6. x = √(4² - 3²)
x = √7

The slope of a line given the table is equal to 0.
How to calculate or determine the slope of a line?In Mathematics and Geometry, the slope of any straight line can be determined by using the following mathematical equation;
Slope (m) = (Change in y-axis, Δy)/(Change in x-axis, Δx)
Slope (m) = rise/run
Slope (m) = (y₂ - y₁)/(x₂ - x₁)
By substituting the given data points into the slope formula, we have the following;
Slope (m) = (9 - 9)/(3 - 1)
Slope (m) = 0/2
Slope (m) = 0.
Based on the table, the slope is the change in y-axis with respect to the x-axis and it is equal to 0.

Consider a football team with a 13
-game schedule. Each game ends with a win (W), a loss (L), or a tie (T). Once the schedule is set, how many ways can the schedule end with 9
wins, 3
losses, and 1
ties?
Answers
Answer:
Step-by-step explanation:
To find the answer, we can use the formula for combinations:
nCr = n! / r!(n-r)!
where n is the total number of games, r is the number of losses, and n-r-1 is the number of ties (since we already know there are 9 wins).
Substituting the values, we get:
13C3 * 10C1
= (13! / 3!10!) * (10! / 1!9!)
= (13*12*11 / 3*2*1) * 10
= 2860
Therefore, there are 2860 ways the schedule can end with 9 wins, 3 losses, and 1 tie.

Step-by-step explanation:
MEDICO Corporation makes several portable electronic devices used in hospitals. Some of these products require rechargeable batteries that MEDICO purchases from various suppliers. Although they try to find them at the best price, they must also consider the quality. In one case, two suppliers were being considered, and batteries were selected from various purchase dates. A test was run on the time the batteries would last in a certain device before it had to be recharged. The results are given in the table below.
Sample Statistics for Survey of Batteries
Supplier Number of Batteries Used in Test Mean Life Standard Deviation
Power+ 45 24 hours 5.1 hours
Electro 61 22 hours 2.6 hours
a) Set up the null and alternative hypotheses to see if the data supports the conclusion that the rechargeable batteries sold by Power+ last longer.
b) Check the conditions.
c) Calculate the test statistic.
d) Find the p-value.
e) Using α = 0.05, state your conclusion in the context of the problem.
Answers
The null hypothesis states that there is no distinction between the mean shelf life of the rechargeable batteries marketed by Power+ and Electro. Whereas, the alternative suggestion maintains that the mean duration of the batteries sold by Power+ stands greater than that of Electro.
The test statistic is 2.24
How to explain the statisticsUtilizing a t-distribution with degrees of freedom akin to the entire sample size minus two (df = n1 + n2 - 2 = 104) alongside the derived test statistic, the p-value can be accessed via calculator or software as 0.014.
As the figure procured from the p-value is lower than the significance level α = 0.05, we invalidate the null positing. The evidence warrants corroborating the allegation that the rechargeable batteries proffered by Power+ remain usable for longer than those provided by Electro.
