a) The distance value is the leverage value from the output which is 0.004
b) The 99% prediction interval is [7.676, 9.146]
a) We are interested in finding and reporting the prediction interval on the output.
Thus, the prediction interval on the output is [7.9188, 8.9025]
Let us consider the estimated value for y as yₓ
We have
x₁ = 3.7, x₂ =3.9, x₃ = 6.5, β₀= 7.5891, β₁ = -2.3577, β₂= 1.6122, β₃= 0.5012
We know that yₓ = β₀ +β₁x₁ + β₂x₂ + β₃x₃
By substituting the value
x₁ = 3.7, x₂ =3.9, x₃ = 6.5, β₀= 7.5891, β₁ = -2.3577, β₂= 1.6122, β₃= 0.5012 into the above equation we get
yₓ =7.5891-(2.3577*3.7)+(1.6122*3,9)+(0.5012*6.5) = 8.411
Let us calculate the value for the prediction interval
The 100 (1 - a) \% prediction interval is
yₓ ±(tₐ/₂ * x * s* √ 1+distance value )
The distance value is the leverage value from the output which is 0.004
We have yₓ =8.411, t₀.₀₀₅.₂₆ =3.067 and s = 0.235. By substituting these values we find that the 95% prediction interval is
8, 411 + (2.3788 * 0.235sqrt(1 + 0.04)) = [7.841, 8, 981]
b) If Enterprise Industry's plan to have in inventory of the number of bottles implied by the upper limit of the prediction interval, which is approximately 9, it can be very confident that it will have enough bottles to meet demand for detergent in the future sales period.
Thus, the bottles are approximately 9
By multiplying the number of bottles implied by the lower limit of the prediction interval, that is approximately 8, by the price of the detergent that is $3.7. we get the minimal revenue from detergent in the future sales period that is $29.6
We are interested in calculating a 99% prediction interval for the demand of detergent in the future sales period
We have yₓ =8.411, t₀.₀₀₅.₂₆ =3.067 and s = 0.235 By substituting these values, we find that the 95% prediction interval is as follows
8, 411 ± (3.067 * 0.235sqrt(1 + 0.04)) = [7.676, 9.146]
Therefore the 99% prediction interval is [7.676, 9.146]

Answers
The correct answer is "not enough information to prove any parallel lines."
What is the special property of two parallel lines?If two lines in a two-dimensional plane are parallel, then the corresponding angles formed by a transversal (a line that intersects both lines) are congruent (i.e., they have the same measure).
Additionally, the alternate interior angles (angles that are on opposite sides of the transversal and inside the pair of parallel lines), as well as the corresponding angles (angles that are in the same position relative to the transversal on the two parallel lines), are also congruent.
In the given diagram, line k is parallel to m, while line a is also parallel to line b but forming a transverse line to line k and line m. Also line k and line m form a transverse line to lines a and b.

Answer:
f(x) = 16*0.75^x
Step-by-step explanation:
first off let's use this coordinate (the one given) :
(0,16)
let's substitute this into the equation with x being 0 and f(x) being 16
16 = a*b^0
*anything to the power of 0 is 1*
so:
a = 16
now use the second coordinate :
(1,12)
and do the same by substituting 1 for x and 12 for f(x), we also know what 'a' is:
12 = 16*b^1
12 = 16 * b
b = 3/4
so :

What is reflection in math?A reflection in mathematics is a mapping from a Euclidean space to itself that is an isometry with a hyperplane as a fixed point set; this set is known as the axis or plane of reflection.
Because the line of reflection has a slope of -1/2, each image point will be on a line with a slope of 2 that passes through the associated pre-image point.
It might be simplest to count the grid squares between the pre-image point and the line, then from the line to the image point's location. Those measurements will be the same.

-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.
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.

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.

suppose tire pressure is normally a distribution random variable with a standard deviation equal to 3 psi. if the car's average tire pressure is on target, what is the probability that the TPMS will trigger a warning? round to 4 decimal places
Answers
The probability of the TPMS triggering a warning is 0.0198 or about 0.02, rounded to four decimal places.
What is a probability?It is used to predict and estimate the likelihood of future events and is calculated by dividing the number of favorable outcomes by the total number of possible outcomes.
Let's assume that the tire pressure follows a normal distribution with a mean of 32 psi and a standard deviation of 3 psi.
Let's also assume that the TPMS warning is triggered when the tire pressure falls below 25 psi or rises above 39 psi.
Using a standard normal distribution table or calculator, we can find the z-scores corresponding to 25 psi and 39 psi:
z₁ = (25 - 32) / 3 = -2.3333
z₂ = (39 - 32) / 3 = 2.3333
Then, we can find the probabilities associated with these z-scores:
P (z < -2.3333) = 0.0099
P (z > 2.3333) = 0.0099
The total probability of the TPMS triggering a warning is the sum of these two probabilities:
P(TPMS warning) = P(z < -2.3333) + P(z > 2.3333) = 0.0099 + 0.0099 = 0.0198
Therefore, the probability of the TPMS triggering a warning is 0.0198 or about 0.02, rounded to four decimal places.

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.
So the value of g is 5, and that is the whole number you can use to unlock the door.
Assume a corporation has earnings before depreciation and taxes of $110,000, deprecation of $48,000, and that is has a 30 percent tax bracket.
A. Compute it's cash flow using the following format.
Earnings before depreciation and taxes?
Depreciation?
Earnings before taxes?
Taxes?
Earnings after taxes?
Depreciation?
Cash flow?
B. How much would cash flow be if there were only $16,000 in depreciation? All other factors are the same.
Cash flow?
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.

The solution of the equation is [tex]z = \frac{[-9 \±9\sqrt{3 i}]}{2}[/tex]
Given is an equation, [tex]\frac{1}{z+9} -\frac{1}{z} = \frac{1}{9}[/tex], we need to solve it,
[tex]\frac{1}{z+9} -\frac{1}{z} = \frac{1}{9}[/tex]
[tex]\frac{z-(z+9)}{z(z+9)} = \frac{1}{9}[/tex]
[tex]\frac{-9}{z^2+9z} =\frac{1}{9}[/tex]
[tex]z^2+9z = -81\\\\z^2+9z+81 = 0[/tex]
Using the quadratic formula,
[tex]x = \frac{[-b \±\sqrt{(b^2-4ac)}]}{2a}[/tex]
here, a = 1, b = 9 and c = 81.
So,
[tex]z = \frac{[-9 \±\sqrt{(81-4(81))}]}{2}\\\\z = \frac{[-9 \±\sqrt{(-243)}]}{2}\\\\\\\\\z[/tex]
[tex]z = \frac{[-9 \±9\sqrt{3 i}]}{2}[/tex]
Hence, the solution of the equation is [tex]z = \frac{[-9 \±9\sqrt{3 i}]}{2}[/tex]
