The percentile rank of the score 71 on the test is 26.7.

What is a percentile?

The value that a specific percentage falls under is known as the percentile. Ben, for instance, is the fourth-tallest child in a group of 20, and eighty percent of the kids are shorter than you.

Given:

58, 64, 66, 70, 71, 75, 77, 80, 84, 85, 87, 90, 93, 95, 96

Calculate the percentile of score 71 as shown below,

[tex]Percentile = n / N \times 100[/tex]

Here, n is the number of scores below 71 and N is the total number of scores,

Percentile = 4 / 15 × 100

Percentile = 0.267 × 100

Percentile = 26.7 percentile

Therefore, the percentile rank of the score 71 on the test is 26.7

commpute how many of those cis contain the true mean. assume that the true mean is 25,000 . store this value in sample hits. does this value match the theoretical value?

Answers

assume that the true mean is 25,000 . store this value in sample hits.No, this value does not match the theoretical value.

This code is calculating the number of "hits" in a list of "CIS" that match the specified true mean of 25,000. The loop iterates through each item in the list and if the value matches the true mean, the sample_hits counter is incremented by one. After the loop has finished iterating through the list, the sample_hits value should represent the number of times the true mean was found in the list. The result does not necessarily match the theoretical value because it is dependent on the contents of the list and whether or not the true mean is actually present.

What are complementary and supplementary angles? How do you find the measure of an unknown angle using these relationships? Give an example and show your work.

Answers

Two angles are called complementary when their measures add up to 90 degrees. Two angles are called supplementary when their measures add up to 180 degrees.

Complementary angles add up to 90°- example: 15° & 75° are complimentary

For example:

Suppose if one angle is x then the other angle will be 90° – x.

Now, to find the complement of 2x + 52°, subtract the given angle from 90 degrees.

90o –  (2x + 52o) =  90o – 2x – 52o  = -2x + 38o

The complement of 2x + 52o is 38o – 2x.

Supplementary angles add up to 180°- example: 50° & 130° are supplementary

if the two angles form a linear angle, such that, if one angle is x, then the other angle is 180° – x

Answers

Mariol pays $12 for a pound of cheese and a pound of sausage, and $42 for 4 pounds of cheese and 1 pound of sausage.

To solve this problem, we can apply simple algebra. Let's use the letter for the initial, C for a pound of cheese, and S for a pound of sausage.

3 C + 3 S = $36

If the sausage cost $2.00 per pound, so

3 C + 3 ($2) = $36

3 C + $6 = $36

To know the price for a pound of cheese, do as follow

3 C = $36 - $6

3 C = $30

1 C = $30 : 3 = $10

Thus, 1 pound of cheese and 1 pound of sausage would be $2 + $10 = $12

Moreover, if 4C + 1S = 4($10) + 1($2) = $40 + $2= $42

Brust's votes equaled 2 times the sum of Pitt's votes and 400:

B = 2(P + 400), this is the first equation

The total number of votes received was 2012:

B + P = 2012, this is the second equation

Solve for P by substitution:

2(P + 400) + P = 20122P + 800 + P = 20122P = 2012 - 8002P = 1212P = 606

Find B:

B =2012 - 606B = 1406

Answer:

a)   Total # of votes:   B + P = 2012

     Brust vs Pitt:   B = 2(P + 400)

b)   1608 = votes for Brust

      404 = votes for Pitt

      Brust won by 1204 votes

Step-by-step explanation:

Given variables:

Let B = the number of votes for BrustLet P = the number of votes for Pitt

Given information:

Brust's votes equalled 2 times the sum of Pitt's votes and 400.The total number of votes received was 2012.

Create a system of linear equations using the given variable and information:

Total # of votes:   B + P = 2012Brust vs Pitt:   B = 2(P + 400)

Substitute the second equation into the first equation and solve for P:

⇒ 2(P + 400) + P = 2012

⇒ 2P + 800 = 2012

⇒ 3P = 1212

⇒ P = 404

Substitute the found value of P into the first equation and solve for B:

⇒ B + 404 = 2012

⇒ B = 1608

Therefore:

1608 = votes for Brust404 = votes for Pitt

To find how many votes Brust won by, subtract the total number of votes for Pitt from the total votes for Brust:

What is the slope of the line that fits Bryce's data?

Answers

y = 7 x is the situation's linear equation in two variables and 7 is Slope of line.

How to calculate Slope?

To determine a line's inclination or steepness, use the slope formula. By calculating the ratio of the change in the y-axis to the change in the x-axis, it may be used to calculate the slope of any line. A line's slope is determined by how its "y" coordinate changes in relation to how its "x" coordinate changes.

Calculation:

The faucet leakage rate is shown here to be 7 gallons per hour.

Since y gallons could leak in x hours , we have

Leakage rate is expressed as gallons per hour divided by the number of hours.

Given that our leakage was y gallons, and

The duration of the leaking is x hours, as well.

7 gallons per hour is the leakage rate, so we have;

Amount of gallons leaked = Gallons leaking per hour × Number of hours

The situation is represented by the linear equation =

y = 7 × x.

By comparing this with y=mx+c, Slope of line is 7

y = 7 x is the situation's linear equation in two variables and 7 is Slope of line.

consider the words consisting of 5 letter "a"'s, 7 letter "b"'s, and 1 letter "c". find the number of such words where there are no two consecutive "b"'s.

Answers

Answer:

To avoid consecutive b's, the string of b's must be divided into one or more groups of 1, 2, or 3 b's. There are a total of 5 + 1 = 6 possible places to insert the dividers to create these groups. For example, suppose we have a string of 7 b's and we insert dividers between the 3rd and 4th b's, and between the 5th and 6th b's. This would create the following groups of b's: bb|bb|b. In general, the number of possible ways to divide the string of b's into groups of 1, 2, or 3 b's is equal to the number of ways to insert 6 dividers into a string of 7 b's. This is equal to the number of ways to choose 6 of the 8 possible places to insert the dividers, which is equal to $\binom{8}{6} = 28$.

Since the 5 a's and the 1 c must be arranged in a specific order, there is only 1 way to arrange these letters. Therefore, the total number of words consisting of 5 letter a's, 7 letter b's, and 1 letter c is equal to $1 \times 28 = 28$.

Answer:

6 possible words.

-----------------------------------------------

According to the question there are 7 'b' s  and we can't have them together. We assume more than two consecutive 'b' s contain two consecutive 'b' s and hence not considering any option of having 3, 4, 6 or 7 'b' s.

There is only one way to place 'b' s apart which leaves us with 6 gaps.

There are 5 + 1 = 6 other letters which is just the number to fill in the gaps between 7 'b' s.

We have only an option for 'c' to have any of the 6 gaps, it gives us 6 options and no other options for 'a' s.

Therefore in total we have 6 possible ways.

How to define the system of linear inequalities?

The system of linear inequalities is defined with linear functions, which have the slope-intercept format given as follows:

y = mx + b.

In which the parameters are given as follows:

m is the slope, representing the change in y when x is increased by one.b is the y-intercept, representing the value of y when the graph of the function crosses the y-axis.

For the upper bound of the inequality, we have that the linear function:

Has a slope of -1, as when x increases by one, y decreases by one.Has an intercept of 1, as when x = 0, y = 1.

Then the upper bound of the inequality has the definition given by:

y ≤ -x + 1.

For the lower bound of the inequality, we have that the linear function:

Has a slope of -0.75, as when x increases by four, y decreases by three.Has an intercept of 0.5, as when x = 0, y = 0.5.

Hence the lower bound of the inequality has the definition given by:

y ≥ -0.75x + 0.5.

What is scale factor?

A scale factor is defined as the ratio between the scale of a given original object and a new object, which is its representation but of a different size.

Given that, A rectangle has a height-to-width ratio of 6.25:4.

4/6.25 = 0.64

The ratio of width to height should be 0.64 for the scaled versions of this rectangle.

A) A rectangle with a height of 18.75 units and a width of 12 units = 12/18.75 = 0.64

B) A rectangle with a height of 50 units and a width of 32 units = 32/50 = 0.64

C) A rectangle with a height of 1.25 units and a width of 0.8 unit = 0.8/1.25 = 0.64

Given the equation. y = x^2 + 4
Write the vertex form equation of each parabola.

A. y = (x + 2)^2 - 4
B. y = (x - 2)^2 + 4
C. y = (x + 4)^2 - 1
D. y = (x + 4)^2 - 2

Answers

Answer:

The vertex form equation of a parabola is y = a(x - h)^2 + k, where (h, k) is the vertex and a is a constant that determines the shape of the parabola.

To write the vertex form equation of each parabola, we need to find the values of a, h, and k for each equation.

A. y = x^2 + 4 To find a, we can compare the coefficients of x^2 in the given equation and the vertex form equation. We see that a = 1 in this case.

To find h and k, we can complete the square for the x-term in the given equation. We add and subtract (b/2a)^2, where b is the coefficient of x and a is the coefficient of x^2.

y = x^2 + 4 y = x^2 + 4 + (0/2)^2 - (0/2)^2 y = x^2 + 4 + 0 - 0 y = (x + 0)^2 + 4 - 0 y = (x + 0)^2 + 4

We see that h = -0 and k = 4 in this case. The vertex form equation is y = (x + 0)^2 + 4, or y = x^2 + 4.

B. y = (x - 2)^2 + 4 This equation is already in vertex form, so we can directly read the values of a, h, and k. We see that a = 1, h = 2, and k = 4 in this case. The vertex form equation is y = (x - 2)^2 + 4.

C. y = (x + 4)^2 - 1 This equation is also already in vertex form, so we can directly read the values of a, h, and k. We see that a = 1, h = -4, and k = -1 in this case. The vertex form equation is y = (x + 4)^2 - 1.

D. y = (x + 4)^2 - 2 This equation is also already in vertex form, so we can directly read the values of a, h, and k. We see that a = 1, h = -4, and k = -2 in this case. The vertex form equation is y = (x + 4)^2 - 2.

find a power series representation for the function. f(x) = x^8 tan^−1(x^3)

The Power series representation of f(x) = [tex]x^8tan^-^1x^3[/tex] is [tex]$$ \Sigma_{n=0}^\infty $$ (-1)^n\frac{x^6^n^+^1^1}{2n+1}[/tex]

What is Maclaurin series?

The Maclaurin series expansion method can be used to get the power series of such functions if the function has a composite part, such as the multiplication or quotient form.

What is power series?

An infinite series in mathematics known as a "power series" can be compared to a polynomial with an infinite number of terms.

The Maclaurin series will be used in this instance to expand the function:

[tex]tan^-^1x[/tex] = [tex]$$ \Sigma_{n=0}^\infty $$ (-1)^n\frac{x^2^n^+^1}{2n+1}[/tex]

and for    [tex]tan^-^1x^3 = $$ \Sigma_{n=0}^\infty $$ (-1)^n\frac{(x^3)^2^n^+^1}{2n+1}[/tex]

=>  [tex]tan^-^1x^3 = $$ \Sigma_{n=0}^\infty $$ (-1)^n\frac{x^6^n^+^3}{2n+1}[/tex]  -------(i)

and f(x) = [tex]x^8tan^-^1x^3[/tex]

now we need to multiply [tex]x^8[/tex] in the above equation to get the power series expansion of f(x)

[tex]x^8tan^-^1x^3[/tex] = [tex]x^8[/tex] [tex]$$ \Sigma_{n=0}^\infty $$ (-1)^n\frac{x^6^n^+^3}{2n+1}[/tex]

=> [tex]$$ \Sigma_{n=0}^\infty $$ (-1)^n\frac{x^6^n^+^3^+^8}{2n+1}[/tex]

=>  [tex]$$ \Sigma_{n=0}^\infty $$ (-1)^n\frac{x^6^n^+^1^1}{2n+1}[/tex]

so the expansion of f(x) = [tex]x^8tan^-^1x^3[/tex] is [tex]$$ \Sigma_{n=0}^\infty $$ (-1)^n\frac{x^6^n^+^1^1}{2n+1}[/tex]

The sum of 5 and y is greater than or equal to -19

Answers

When the sum of 5 and y is greater than or equal to -19, the inequality is y ≥ - 24.

How to illustrate the inequality?

Inequalities are created through the connection of two expressions. It should be noted that the expressions in an inequality aren't always equal. Inequalities implies that the expressions are not equal. They are denoted by the symbols ≥ < > ≤.

Since the sum of 5 and y is greater than or equal to -19, this will be:

5 + y ≥ - 19

y ≥-19 - 5.

Two-sevenths of the students in the theater club will be in the second show, and three-fifths of them will be in the third show. The rest will be in the first show. If there are 70 students in the theater club, how many of them will be in the first show?

Answers

Answer:

8 students

Step-by-step explanation:

Let's say there are x students in the theater club. We can set up the following equations to represent the information given in the problem:

2/7 * x = number of students in the second show3/5 * x = number of students in the third showx - (2/7 * x + 3/5 * x) = number of students in the first show

We are told that there are 70 students in the theater club, so we can substitute 70 for x in the equations above to find the number of students in each show:

2/7 * 70 = 20 students in the second show3/5 * 70 = 42 students in the third show70 - (2/7 * 70 + 3/5 * 70) = 8 students in the first show

Therefore, there will be 8 students in the first show.
