The function graphed on the axis above should be expressed as a piecewise function as follows;
f(x) = x + 1 {x < -5}
= 5x - 10 {x > 1}
How to determine the piecewise function?In order to determine the piecewise function, we would determine an equation that represent each of line shown on the graph. Therefore, we would determine the slope of this line;
Slope (m) = (y₂ - y₁)/(x₂ - x₁)
Slope (m) = (-7 + 4)/(-8 + 5)
Slope (m) = -3/-3
Slope (m) = 1.
At data point (-5, -4) and a slope of 1, a linear equation for this line can be calculated by using the point-slope form as follows:
y - y₁ = m(x - x₁)
y + 4 = 1(x + 5)
y = x + 1
1, -5 2 0
For the second line, we have:
Slope (m) = (0 + 5)/(2 - 1)
Slope (m) = 5/1
Slope (m) = 5.
At data point (2, 0) and a slope of 5, a linear equation for this line can be calculated by using the point-slope form as follows:
y - y₁ = m(x - x₁)
y - 0 = 5(x - 2)
y = 5x - 10

Consider the demand for fresh detergent in a future sales period
Answers
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]

A quantity with an initial value of 480 grows exponentially at a rate such that the quantity doubles every 6 minutes. What is the value of the quantity after 0.2 hours, to the nearest hundredth?
answer 1920
Answers
The value of quantity after 0.2 hours is, 960
Given that;
A quantity with an initial value of 480 grows exponentially at a rate such that the quantity doubles every 6 minutes.
We know that;
The exponential growth function is
A = A₀ (1 + r)ⁿ
Where, A= The number of quantity after t days
A₀ = initial number of quantity
r = rate of growth
n = time in minutes
A quantity with an initial value of 830 grows at a rate such that the quantity doubles in 0.2 hours = 12 minutes
And, A = 2 x 480 = 960
A₀ = 480
n = 12 minutes
r = ?
⇒ A = A₀ (1 + r)ⁿ
⇒ 960 = 480 (1 + r)¹²
⇒ 2 = (1 + r)¹²
⇒ [tex]r = \sqrt[12]{2} - 1[/tex]
Now, to find the quantity after 12 minutes, we plug A = 830, t = 12 minutes in exponential function;
⇒ A = A₀ (1 + r)ⁿ
⇒ [tex]A = 480 (1 + \sqrt[12]{2} - 1)^{12}[/tex]

A school dance committee is to consist of 2 freshmen, 3 sophomores, 4 juniors, and 5 seniors. If 7 freshmen, 8 sophomores, 7 juniors, and 7 seniors are eligible to be on the committee, in how many ways can the committee be chosen?
Answers
The problem can be solved using combinations. We need to choose 2 freshmen from 7, 3 sophomores from 8, 4 juniors from 7, and 5 seniors from 7. The number of ways to do this is:
C(7,2) * C(8,3) * C(7,4) * C(7,5) = 21 * 56 * 35 * 21 = 2,756,040.
Therefore, there are 2,756,040 ways to form the dance committee.
The number of ways to choose 2 freshmen from 7 is 7C2 = 21.
The number of ways to choose 3 sophomores from 8 is 8C3 = 56.
The number of ways to choose 4 juniors from 7 is 7C4 = 35.
The number of ways to choose 5 seniors from 7 is 7C5 = 21.
To find the total number of ways to choose the committee, we multiply these numbers together:
21 x 56 x 35 x 21 = 2,849,680
Therefore, there are 2,849,680 ways to choose the dance committee.

Answers
To find the ordered pair solutions for the system of equations y = -x² + 2 and y = x, we can set the two equations equal to each other:
-x² + 2 = x
Now we can rearrange this equation into standard quadratic form by moving everything to one side:
-x² + x + 2 = 0
We can solve this quadratic equation using the quadratic formula:
x = (-b ± √(b² - 4ac)) / 2a
where a = -1, b = 1, and c = 2
Plugging these values into the formula, we get:
x = (-1 ± √(1 - 4(-1)(2))) / 2(-1)
x = (-1 ± √9) / (-2)
x = (-1 ± 3) / (-2)
So the solutions for x are x = -1 and x = -2.
To find the corresponding values of y, we can plug these values of x into either of the original equations. Let's use y = x:
When x = -1, y = -1
When x = -2, y = -2
Therefore, the ordered pair solutions for this system of equations are (-1, -1) and (-2, -2).

C. 100
D. 16
Answers
The wildlife group can estimate that there are 100 wild hogs in the area. The answer is C.
Define the capture-recapture method?The basic idea behind this method is that if we capture a random sample of animals from a population, tag them, and release them back into the population, then later capture another sample of animals, the ratio of tagged to untagged animals in the second sample can be used to estimate the total population size.
To estimate the total population of wild hogs in the area, we can use the capture-recapture method.
In this case, the wildlife group tagged and released 20 wild hogs, and later counted 8 wild hogs out of the 40 they saw. We can set up a proportion to estimate the total population size:
(Tagged hogs in first sample) / (Total population size) = (Tagged hogs in second sample) / (Number of hogs in second sample)
Putting the values,
⇒ 20 / x = 8 / 40
Simplifying and solving for x, we get:
⇒ x = (20 × 40) / 8 = 100
⇒ x = 100
Therefore, the wildlife group can estimate that there are 100 wild hogs in the area. The answer is C.

What is the total cost of interest?
Note: Do not round intermediate calculations. Round your answer to the nearest whole dollar.
Answers
Answer:
Step-by-step explanation:
To find the total cost of interest, we first need to find the total payment over the life of the loan:
Total payment = Monthly payment x Number of payments
Total payment = $370.41 x (30 x 12)
Total payment = $133,347.60
Next, we need to subtract the principal (loan) amount to find the total interest paid:
Total interest = Total payment - Principal
Total interest = $133,347.60 - $69,000
Total interest = $64,347.60
Rounding to the nearest whole dollar, the total cost of interest is $64,348.

Answers
Thus, the given system of equation has one unique solution (-3, 6).
Explain about the system of equations:Two or even more equations with the same variables are referred to be a system of equations. The intersection of the lines is the location where an equation system has a solution. Systems of equations can be solved using one of four techniques: graphing, substitution, elimination, or matrices.
Given: system of equations:
y = 3x + 15 ...eq 1
3x + 3y = 9 (divide by 3)
x + y = 3
y = 3 - x ..eq 2
equation eq 1 and eq 2
3x + 15 = 3- x
3x + x = 3 - 15
4x = -12
x = -3
y = 3 - (-3) = 3 + 3 = 6
Solution - (-3, 6)
Thus, the given system of equation has one unique solution (-3, 6).

The diameter of the lead in a pencil p must be within 0.01 millimeters of 1 millimeter
Answers
The diameter of the lead in a pencil p must be within 0.01 millimetre of 1 millimeter. In the form of inequality, this can be expressed as 0.01<p<1.
A mathematical expression with values that on the left and right are not equal is referred to as having an inequality. In essence, an inequality examines any two values as well as demonstrates whether one is bigger than, less than, or neither greater nor less than the comparable quantity. Numbers are compared using inequalities to determine the range of quantities that fall inside the parameters of a variable. The diameter of the lead in a pencil p must be within 0.01 millimetre of 1 millimeter. This can be expressed as 0.01<p<1 inequality.

Answers
The 50th partial sum of the given arithmetic sequence is 4600
Calculating partial sum of an arithmetic sequenceFrom the question, we are to calculate the 50th partial sum of the given arithmetic sequence
The given arithmetic sequence is
-6, -2, 2, 6, ...
To find the 50th partial sum of the sequence, we will find the sum of the first 50 terms in the sequence.
The sum of n terms of a sequence is given by the formula,
S = n/2(a + l)
Where a is the first term
and l is the last term
l is given by
l = a + (n - 1)d
Where d is the common difference
In the given series
a = -6
d = -6 -(-2) = -6 + 2 = 4
Thus,
l = -6 + (50 - 1)4
l = -6 + 49×4
l = -6 + 196
l = 190
Then,
S = 50/2(-6 + 190)
S = 25(184)
S = 4600
Hence,
The sum is 4600

Solve for x. Enter the solutions from least to greatest.
(x - 10)² - 1 = 0
lesser x =
greater x =
Answers
Answer:
lesser x = 9
greater x = 11
Step-by-step explanation:
(x-10)² - 1 = 0
(x-10)² = 1
(x-10) = +- root1 (positive and negative root1)
So (x-10) = +1 and (x-10) = -1
Firstly
X - 10 = 1
X = 11
Secondly
X - 10 = -1
X = 9
So you have x = 9, and x = 11
The smaller one is the lesser x (9)
The larger one is the greater x (11)
