Procedure for Systematic Random Sampling
First, divide the population size by the sample size and round the result down to the nearest whole number, m.
Then, use a random-number table or a similar device to obtain a number, k, between 1 and m.
Finally, select for the sample those members of the population that are numbered k, kplus+m, kplus+2m,
Apply the procedure to determine the sample (that is, the numbers corresponding to the members of the population that are included in the sample), using the provided random-number table. To use the random-number table, Start at the two-digit number at the top left, read down the column, up the next, and so on.
The value of k for this sample is?
(Type a whole number.)
The sample is ?
(Type whole numbers. Use a comma to separate answers asneeded.)
b. Suppose that the random sample chosen from the random number table is 22 number chosen from the random number table is 22 (that is k=22) Determine the sample.
The sample is-
The sample is 3, 71, 139, 207, and 275.
The procedure for systematic random sampling involves first dividing the population size by the sample size and rounding the result down to the nearest whole number, m. This value of m is known as the sampling interval. For the given population size of 341 and sample size of 5, the value of m is 68.
Next, a random number, k, between 1 and m is chosen. The given random-number table contains the values 03184, 61921, 87377, 97729, and 79151. Reading the two-digit number at the top left, we get 03, which is equal to 3. Therefore, k = 3.
Finally, the sample is taken from the population in intervals of m. In this case, the sample consists of members of the population numbered 3, 71, 139, 207, and 275. Therefore, the sample is 3, 71, 139, 207, and 275.

.Most of Conservative Casey’s money is invested in a savings account that pays 1%
interest a year, but some is invested in a risky stock fund that pays 7% a year. Casey’s
total initial investment in the two accounts was $10000. At the end of the first year, Casey
received a total of $250 in interest from the two accounts. Find the amount initially invested
in each
The amount Casey invested in the certificate of deposit is; $60,000.
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
Assume that
0.01c - 0.02s = $250---equation 1
c + s = $10,000 ------ equation 2
Where: c = amount invested in the certificate of deposit
s = amount invested in the savings account
Now Multiply equation 2 by 0.01:
0.01c + 0.01s = 100 equation 3
Subtract equation 3 from equation 1:
0.01s = 100
Divide both sides of the equation by 0.01:
s = 100 / 0.01
s = 10,000
Substitute for s in equation 2:
c + 10,000 = 70,000
c = 70,000 - 10,000

What is the expanded form for this expression?
a triangle has an area of 16 in2, and two of the sides of the tri- angle have lengths 5 in. and 7 in. find the angle included by these two sides.
The angle included by these two sides is (c^2 - 74) / (-70).
What is triangle ?
A triangle is a polygon with three edges and three vertices. It is one of the basic shapes in geometry. A triangle with vertices A, B, and C is denoted triangle ABC.
The area of a triangle can be found using the formula:
Area = (1/2) * b * h,
where b is the length of the base and h is the height of the triangle.
Since two of the sides have lengths 5 in and 7 in, we can assume that they are the base and the height of the triangle, respectively. Setting b = 5 in and h = 7 in, we can find the area:
Area = (1/2) * 5 in * 7 in = (1/2) * 35 in^2 = 16 in^2.
This means that the height of the triangle is 7 in and the base is 5 in. To find the angle included by these two sides, we can use the Law of Cosines:
c^2 = a^2 + b^2 - 2ab * cos(C),
where a and b are the lengths of the sides and C is the angle included by these two sides.
Since a = 5 in and b = 7 in, we can find the angle C:
c^2 = a^2 + b^2 - 2ab * cos(C)
c^2 = 5^2 + 7^2 - 2 * 5 * 7 * cos(C)
c^2 = 25 + 49 - 70 * cos(C)
c^2 = 74 - 70 * cos(C)
So , The angle included by these two sides is (c^2 - 74) / (-70).

find the volume v of the solid obtained by rotating the region bounded by the given curves about the specified line. y = 5x5, y = 5x, x ≥ 0; about the x-axis
The volume of the solid obtained by rotating the region bounded by the curves y = 5[tex]x^5[/tex] and y = 5x about the x-axis is -(8π/21) cubic units.
We have,
To find the volume of the solid obtained by rotating the region bounded by the curves y = 5[tex]x^5[/tex] and y = 5x about the x-axis, we can use the method of cylindrical shells.
The region bounded by the curves is between x = 0 and x = 1.
Let's consider an infinitesimally thin strip of width dx at a distance x from the y-axis.
The height of this strip will be the difference between the two curves:
(5[tex]x^5[/tex]) - (5x).
The circumference of the shell at this distance x is 2πx (since we are rotating about the x-axis).
Therefore,
The volume of this infinitesimally thin shell is given by:
dV = (2πx) x [(5[tex]x^5[/tex]) - (5x)] x dx.
To find the total volume, we integrate this expression over the interval [0, 1]:
V = ∫(0 to 1) (2πx) x [(5[tex]x^5[/tex]) - (5x)] dx.
Simplifying the expression inside the integral:
V = 2π ∫(0 to 1) [(5[tex]x^6[/tex]) - (5x²] dx.
Integrating term by term:
V = 2π [([tex]x^7[/tex])/7 - (x³)/3] evaluated from 0 to 1.
Substituting the limits of integration:
V = 2π [(([tex]1^7[/tex])/7 - (1³)/3) - (([tex]0^7[/tex])/7 - (0³)/3)].
Simplifying:
V = 2π [(1/7 - 1/3) - (0 - 0)].
V = 2π [(3 - 7)/21].
V = 2π (-4/21).
V = -(8π/21).
Therefore,
The volume of the solid obtained by rotating the region bounded by the curves y = 5[tex]x^5[/tex] and y = 5x about the x-axis is -(8π/21) cubic units.

What is the absolute minimum value of y =-cos(x) - sin(x) on the closed interval [0,π/2]? Justify your answer
The absolute minimum value of y =-cos(x) - sin(x) on the closed interval [0, π/2] is [tex]-\sqrt{2}[/tex]
Consider equation,
y = -cos(x) - sin(x)
Let y = f(x)
Differentiate the function f(x) = -cos(x) - sin(x) with respect to x.
f'(x) = -(-sin(x)) - cos(x)
f'(x) = sin(x) - cos(x)
For f'(x) = 0,
sin(x) - cos(x) = 0
sin(x) = cos(x)
sin(x)/cos(x) = 1
tan(x) = 1 ..............(tan(θ) = sin(θ)/cos(θ))
x = π/4
For above value of x, the value of function would be,
f(π/4) = -cos(π/4) - sin(π/4)
f(π/4) = [tex]-\frac{1}{\sqrt{2} } -\frac{1}{\sqrt{2} }[/tex]
f(π/4) = [tex]-\sqrt{2}[/tex]
f(0) = -cos(0) - sin(0)
f(0) = -1
And f(π/2) = -cos(π/2) - sin(π/2)

a total of 35% of americans smoke cigarettes, 15% smoke cigars and 7% smoke both cigarettes and cigars. a. what percentage smoke something (cigars, cigarettes or both)? b. what percentage smoke neither cigars nor cigarettes? c. what percentage smoke cigars but not cigarettes? d. what is the conditional probability that a randomly selected person smokes cigarettes given that he smokes cigars? g
The solution of each part of the question is given below:
a. Let C be the event that a person smokes cigars, and let S be the event that a person smokes cigarettes. The percentage of Americans who smoke either cigars, cigarettes, or both can be calculated as P(C U S), where U represents the union of two events. From the given information, P(C) = 15% and P(S) = 35%. The probability that a person smokes both cigars and cigarettes is 7%, so P(C ∩ S) = 7%.
P(C U S) = P(C) + P(S) - P(C ∩ S)
P(C U S) = 15% + 35% - 7% = 43%
So, 43% of Americans smoke either cigars, cigarettes, or both.
b. The percentage of Americans who smoke neither cigars nor cigarettes can be calculated as P(C' ∩ S'), where C' represents the complement of event C (not smoking cigars) and S' represents the complement of event S (not smoking cigarettes).
P(C' ∩ S') = 100% - P(C U S)
P(C' ∩ S') = 100% - 43% = 57%
So, 57% of Americans smoke neither cigars nor cigarettes.
c. The percentage of Americans who smoke cigars but not cigarettes can be calculated as P(C ∩ S').
P(C ∩ S') = P(C) - P(C ∩ S)
P(C ∩ S') = 15% - 7% = 8%
So, 8% of Americans smoke cigars but not cigarettes.
d. The conditional probability that a person smokes cigarettes given that he smokes cigars can be calculated as P(S | C), where S represents the event that a person smokes cigarettes and C represents the event that a person smokes cigars.
P(S | C) = P(S ∩ C) / P(C)
P(S | C) = 7% / 15% = 0.47
So, the conditional probability that a randomly selected person smokes cigarettes given that he smokes cigars is 0.47, or 47%.

Since not all of the leading coefficients are ones and not all of the rows are in descending order, the above linear equation is not in echelon form.
No, an echelon form does not exist for the given linear system. All leading coefficients must be 1 for the structure to be in echelon form, and all rows must be arranged in decreasing order. The second and third rows in this equation are not in decreasing order, and the leading coefficient in the first row is 2, not 1.
An echelon form cannot be described by the given linear system. All of the leading coefficients in the equations must be 1, and all of the rows must be arranged in descending order for the equation to be in echelon form. The leading coefficient of the first row in the preceding equation is 2, not 1, and the second and third rows are not arranged in descending order. The equation is therefore not in echelon form.

Approximately 86.5% of customers will be served in less than 10 minutes and only 13.5% of customers will take more than 10 minutes to check out.
Exponential Checkout Time ProportionTo find the proportion of customers who take more than 10 minutes to check out, we need to calculate the cumulative distribution function (CDF) of an exponential distribution at 10 minutes and subtract it from 1. The CDF for an exponential distribution with mean (lambda) 5 minutes is given by:
CDF = 1 - e^(- λ * x)
Plugging in λ = 0.2 (1/mean) and x = 10, we get:
CDF = 1 - e^(-0.2 * 10) = 1 - e^(-2) = 1 - 0.135 = 0.865

solve the following initial value problems for y(t) by antidifferentiation or by aseparation of variables: dy dt = y t cos( ) y; y(0) = 2
y(t) = 2e^(sin(t) + t) is the antiderivative of the function dy/dt = y cos(t) + y, and satisfies the initial condition y(0) = 2.
This is a first-order linear differential equation, which can be solved by the separation of variables. To do so, we can start by writing:
dy/dt = y cos(t) + y
We can divide both sides by y:
dy/dt / y = cos(t) + 1
Now, we can integrate both sides with respect to t, using the property that d(ln y)/dt = 1/y:
∫(dy/dt / y) dt = ∫(cos(t) + 1) dt
ln|y| = sin(t) + t + C
Where C is the constant of integration. To find its value, we can use the initial condition y(0) = 2:
ln|2| = sin(0) + 0 + C
C = ln|2|
Therefore, the solution of the initial value problem is:
y(t) = 2e^(sin(t) + t)
This is the antiderivative of the function dy/dt = y cos(t) + y and satisfies the initial condition y(0) = 2.

Assuming that the standard deviation remains 0.12 ounces, so 16.251 ounces mean weight should Buckley Farms use.
The total weight of each bag follows an approximately normal distribution with a mean of 16.15 ounces and a standard deviation of 0.12 ounces.
Mean (μ) = 16.15
Standard deviation, (σ) = 0.12
n = 6
Buckley Farms decides to increase the mean weight of each bag of chips so that only 5%(0.05) of the bags have weights that are less than 16 ounces. So
P(X > x) = 0.05
P[(X - μ)/(σ/√n) > (x - μ)/(σ/√n)] = 0.05
1 - P(Z ≤ z) = 0.05
Subtract 1 on both side , we get
P(Z ≤ z) = 0.95
z = 1.96
(x' - μ)/(σ/√n) = 1.645
Now putting the value
(x' - 16.15)/(0.15/√6) = 1.645
(x' - 16.15)/(0.15/2.45) = 1.645
(x' - 16.15)/(0.0612) = 1.645
Multiply by 0.0612 on both side, we get
x' - 16.15 = 0.100674
Add 16.15 on both side, we get

To show the given two triangles are similar, choose option D.
What are similar triangles?If in two triangles the ratio of corresponding sides are equal, and all corresponding angles are equal then they are considered as similar triangles.
Given that, two triangles are similar Δ STW ~ Δ XYZ,
According to definition of similar triangles,
The ratio of corresponding sides are equal, and all corresponding angles are equal,
Therefore, we have,
ST/XY = TW/YZ = SW/XZ
And,
Angles A, B and C are equal to Angles X, Y and Z respectively.
From the above discussion we can conclude, the correct options are;
To show the given two triangles are similar, we should have all the given sides in equal proportion.
As we are already given that, ST = 27 and XY = 9
The scale factor is 1/3
So, we should consider the option D, SW = 15 and TW = 24
By this we can get, SW/XZ = 3 and TW/YZ = 3
Hence, the correct option is D

Practice 7-3 Constructing Bisectors (PLEASE HELP)
Therefore , the solution of the given problem of angle bisector comes out to be each measurement will be equivalent to 30 degrees,
What is an Angle Bisector?A bisector exists for each angle. Additionally, it is the symmetry line that connects an angle's two arms, triangle whose construction facilitates the creation of smaller angles.
Here,
A 30° angle, for example, might be called for. A 60° angle can be made, and it can then be divided, to accomplish this.
The concept of an angle bisector is used to construct angles such as 90 degrees, 45 degrees, 15 degrees, and others.
Examples :
What is each angle's measurement if an angle bisector divides an angle of 80 degrees?
The answer is that 80 degrees is the measure of an angle.
It is common knowledge that the angle is divided into two equal pieces by the angle bisector.
Consequently, 80 degrees is divided into two equal portions, let's call x.
Hence,
x + x = 80°
2x = 80°
x = 80°/2
x = 40°.
The second option is ineffective since it would result in A' being positioned at (-5, 2) after translation A 3 up and 1 left (5, -2).
The third option: spinning A in a clockwise direction 90 degrees places it at (-1, 4), then reflecting it across the y-axis places it at (1, 4).
In the fourth option, A is rotated 90 degrees counterclockwise, putting it at (1, -4), and it is reflected across the x-axis, putting it at (1, 4).
The fifth option is to rotate A 180 degrees, which positions it at (-3, -4), after translating 3 down & 1 right (3, 4). B(-5, -5) (-5, -5) Translated results in (-4, -8), and rotated results in (4, 8). Translation of C(-3, -4) results in (-2, -7), and rotation results in (2, 7).
