Grade X: 568, 570, 575, 578, 584
Grade Y: 573, 574, 575, 577, 578
a. Compute the mean, median, and standard deviation for each grade of tire.
b. What would be the effect on your answers in (a) and (b) if the last value for grade Y was 588 instead of 578? Explain.
c. Which grade of tire is providing better quality? Explain.

Answers

Answer:

See Explanation for answers

Step-by-step explanation:

Given

\(Grade\ X: 568, 570, 575, 578, 584\)

\(Grade\ Y: 573, 574, 575, 577, 578\)

Solving (a): Mean, median, and standard deviation of both grades

Mean is calculated as:

\(Mean = \frac{\sum x}{n}\)

For grade X:

\(Mean = \frac{568 + 570+ 575+578+584}{5}\)

\(Mean = \frac{2875}{5}\)

\(Mean = 575\)

For Grade Y

\(Mean = \frac{573+ 574+ 575+ 577+ 578}{5}\)

\(Mean = \frac{2877}{5}\)

\(Mean = 575.4\)

\(Median = \frac{N+1}{2}th\)

\(Median = \frac{5+1}{2}th\)

\(Median = \frac{6}{2}th\)

\(Median = 3rd\ item\)

For grade X and Y.

\(Median = 575\)

Standard deviation (s) is calculated as:

\(s = \sqrt{\frac{\sum(x_i - \bar x)^2}{n}}\)

For Grade x

\(s = \sqrt{\frac{(568 - 575)^2+(570 - 575)^2+(575 - 575)^2+(578- 575)^2+(584- 575)^2}{5}}\)

\(s = \sqrt{\frac{164}{5}}\)

\(s = \sqrt{32.8}\)

\(s = 5.73\)

For Grade Y

\(s = \sqrt{\frac{(573 - 575.4)^2+(574 - 575.4)^2+(575 - 575.4)^2+(577 - 575.4)^2+(578 - 575.4)^2}{5}}\)

\(s = \sqrt{3.44}\)

\(s = 1.85\)

Solving (b): If the last value is  b, the following will occur.

The mean will increase.

The median will remain unaltered

The standard deviation will increase.

See proof below

For Grade Y: Mean is:

\(Mean = \frac{573+ 574+ 575+ 577+ 588}{5}\)

\(Mean = \frac{2887}{5}\)

\(Mean = 577.4\)

Median still remains the 3rd item.

\(Median = 575\)

The standard deviation is:

\(s = \sqrt{\frac{(573 - 575.4)^2+(574 - 575.4)^2+(575 - 575.4)^2+(577 - 575.4)^2+(588 - 575.4)^2}{5}}\)

\(s = \sqrt{\frac{169.2}{5}}\)

\(s = \sqrt{33.84}\)

\(s = 5.82\)

Solving (c): Which grade provides better quality.

Grade X provides better quality.

This is so because the mean value, the standard deviation of grade X is greater than grade Y

Mean medium and standard deviation are the statistics tools used to measure the center tendency of the given data set.

The mean, medium standard deviation are computed and value obtained.  If value last value of data set Y is 588 instead of 578 the mean and standard deviation will increase but medium will remain same for data set Y.The value of mean and standard deviation of the Tyre X is greater thus the Tyre X provide the better quality.

Given information-

Grade X: 568, 570, 575, 578, 584

Grade Y: 573, 574, 575, 577, 578

a) Compute the mean, median, and standard deviation for each grade of tire.Mean

Mean is the average of the given data or the ratio of the sum of the given data set to the number of data in the set.

Mean for grade X,

\(\overline x=\dfrac{568+570+575+578+584}{5} \\ \overline x=575\)

Mean for grade Y,

\(\overline x=\dfrac{573+574+575+577+578}{5} \\ \overline x=575.4\)

Median

Median is the middle number when the data set is arranged in the assenting or descending order.

The middle number for both the data set is 575 milimeter. Thus the median is 575 for both the data set.

Standard deviation

Standard deviation refers that how much the group member of a data set is differ from the mean value. Standard deviation can be given as,

\(\sigma=\sqrt{\dfrac{\sum(x_i-\mu)^2}{N} } \)

Standard deviation for X

\(\sigma=\sqrt{\dfrac{(568-575)^2+(570-575)^2+(575-575)^2+(578-575)^2+(584-575)^2}{5} } \\ \sigma=5.73\)

Standard deviation for Y

\(\sigma=\sqrt{\dfrac{(573-575.4)^2+(574-575.4)^2+(575-575.4)^2+(577-575.4)^2+(578-575.4)^2}{5} } \\\sigma=1.85\)

b) Effect on the answers in (a) and (b) if the last value for grade Y was 588 instead of 578.

Mean for grade Y,

\(\overline x=\dfrac{573+574+575+577+588}{5} \\ \overline x=577.4\)

Thus the mean increased with value 2 mm.

Medium remain the same as the middle value is still 575.

Standard deviation for Y

\(\sigma=\sqrt{\dfrac{(573-575.4)^2+(574-575.4)^2+(575-575.4)^2+(577-575.4)^2+(588-575.4)^2}{5} } \\\sigma=5.82\)

c) Tire which provide better quality-

The value of mean and standard deviation of the Tyre X is greater thus the Tyre X provide the better quality.

Hence

The Mean medium and standard deviation are computed and value obtained.  If value last value of data set Y is 588 instead of 578 the mean and standard deviation will increase but medium will remain same for data set Y.The value of mean and standard deviation of the Tyre X is greater thus the Tyre X provide the better quality.

HELPPPP PLEASE

Answers

f = 202

Step-by-step explanation:

\(7 \times 5f = 7070\)

\(5f = \frac{7070}{7} \)

\(5f = 1010\)

\(f = \frac{1010}{5} \)

\(f = 202\)

Verification to check the given answer is correct, then put the value of f in the given question.

\(7 \times 5(202) = 7070\)

\(35(202) = 7070\)

\(7070 = 7070\)

L.H.S. = R.H.S

\({ \green { \boxed{ \red{ \sf{f = 202}}}}}\)

Step-by-step explanation:

The given Eqⁿ is, \({ \purple{ \sf{7 \times 5f = 7070}}}\)

We need to find the value of f. So, let us cancel the numbers one by one.

First, let us cancel 7 by dividing both the sides by 7 in the given Eqⁿ.

\({ \purple{ \sf \frac{ \cancel7 \times 5f}{ \cancel7}}} = { \purple{ \sf{ \frac{ \cancel{7070} ^{ \green{ \tt{1010}}} }{ \cancel 7_{ \green{ \tt{1}}}}}}}\)

\({ \purple{ \sf{5f = 1010}}}\)

Now, let us cancel 5 by dividing both the sides by 5. then,

\({ \purple{ \sf{ \frac{ \cancel5}{ \cancel5}f}}} = { \purple{ \sf{ \frac{ \cancel{1010^{ \red{ \tt{ \: \:202}}}}}{ \cancel 5_{ \red{ \tt{1}}}}}}}\)

Answer:

Multiply the top equation by -3 and the bottom equation by 2

Step-by-step explanation:

Given system of equations:

\(\begin{cases}4x-2y=7\\3x-3y=15 \end{cases}\)

To solve the given system of equations by addition, make one of the variables in both equations sum to zero.  To do this, the chosen variable must have the same coefficient, but it should be negative in one equation and positive in the other, so that when the two equations are added together, the variable is eliminated.

To eliminate the variable y:

Multiply the top equation by -3 to make the coefficient of the y variable 6:

\(\implies -3(4x-2y=7) \implies -12x+6y=-21\)

Multiply the bottom equation by 2 to make the coefficient of the y variable -6:

\(\implies 2(3x-3y=15) \implies 6x-6y=30\)

Add the two equations together to eliminate y:

\(\begin{array}{l r r}& -12x+6y= &-21\\+ & 6x-6y= & 30\\\cline{1-3}& -6x\phantom{))))))} = & 9\end{array}\)

Solve for x:

\(\implies -6x=9\)

\(\implies x=-\dfrac{9}{6}=-\dfrac{3}{2}\)

Substitute the found value of x into one of the equations and solve for y:

\(\implies 3\left(-\dfrac{3}{2}\right)-3y=15\)

\(\implies -\dfrac{9}{2}-3y=15\)

\(\implies -3y=\dfrac{39}{2}\)

\(\implies y=-\dfrac{39}{2 \cdot 3}\)

\(\implies y=-\dfrac{13}{2}\)

4. The average salary for public school teachers for a specific year was reported to be $39,385. A random sample of 50 public school teachers in a particular state had a mean of $41,680, and the population standard deviation is $5975. Is there sufficient evidence at the a _ 0.05 level to conclude that the mean salary differs from $39,385

Answers

Answer:

The p-value of the test is 0.0066 < 0.05, which means that there is sufficient evidence at the 0.05 significance level to conclude that the mean salary differs from $39,385

Step-by-step explanation:

The average salary for public school teachers for a specific year was reported to be $39,385. Test if the mean salary differs from $39,385

At the null hypothesis, we test if the mean is of $39,385, that is:

\(H_0: \mu = 39385\)

At the alternative hypothesis, we test if the mean differs from this, that is:

\(H_1: \mu \neq 39385\)

The test statistic is:

\(z = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}\)

In which X is the sample mean, \(\mu\) is the value tested at the null hypothesis, \(\sigma\) is the standard deviation and n is the size of the sample.

39385 is tested at the null hypothesis:

This means that \(\mu = 39385\)

A random sample of 50 public school teachers in a particular state had a mean of $41,680, and the population standard deviation is $5975.

This means that \(n = 50, X = 41680, \sigma = 5975\)

Value of the test statistic:

\(z = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}\)

\(z = \frac{41680 - 39385}{\frac{5975}{\sqrt{50}}}\)

\(z = 2.72\)

P-value of the test and decision:

The p-value of the test is the probability that the sample mean differs from 39385 by at least 2295, which is P(|Z| > 2.72), which is 2 multiplied by the p-value of Z = -2.72.

Looking at the z-table, Z = -2.72 has a p-value of 0.0033

2*0.0033 = 0.0066

The p-value of the test is 0.0066 < 0.05, which means that there is sufficient evidence at the 0.05 significance level to conclude that the mean salary differs from $39,385

One tablecloth 48 inches wide & 72 inches long. Want 2nd tablecloth 30 inches wide how long should it be

Answers

The length (in inches) of the second tablecloth is 43.75 inches

How to determine the length of the second tablecloth?

From the question, we have the following parameters that can be used in our computation:

Width = 48 inches. and Length = 72 inches ⇒ Small tablecloth

Width = 30 inches. and Length = ?? inches ⇒ Large tablecloth

Represent the unknown length with x

So, we have

Width = 48 inches. and Length = 72 inches ⇒ Small tablecloth

Width = 30 inches. and Length = x inches ⇒ Large tablecloth

This shows a direct variation

So, we cross multiply the equation

x * 48 = 70 * 30

So, we have

x = 70 * 30/48

Evaluate

x = 43.75

Hence, the length is 43.75 inches

Which set of values could be the side length of a 30 60 90 triangle? A. {5,5v3,10}

Answers

Therefore, the answer is A. {5, 5√3, 10}.

The set of values {5, 5√3, 10} could be the side lengths of a 30-60-90 triangle.

In a 30-60-90 triangle, the sides are in a specific ratio. The ratio is 1 : √3 : 2, where the shortest side (opposite the 30-degree angle) has length x, the side opposite the 60-degree angle has length x√3, and the hypotenuse (opposite the 90-degree angle) has length 2x.

Let's check if the given set of values satisfies this ratio:

   If x= 5, then the side opposite the 60-degree angle should be 5√3, and the hypotenuse should be 10. These values match the ratio, so the set {5, 5√3, 10} could be the side lengths of a 30-60-90 triangle.

But since they gave us the diameter we are gonna have to use the first formula.

Now I don’t know if they want u to use 3.14 for pi or the actual number, so i’m gonna assume we are using the actual formula.

So the formula to be able to find the diameter of circle A is going to be:
118/pi.
So put that into your calculator and you get 37.5605mm or 37.56mm.
It depends on what place your instructor wants you to round to.

The formula for circle B is going to be:
1/pi.
So let us put that into our calculator and you get 0.318309mm etc. Or just 0.3183.

I believe that I am correct but if i’m not please correct me.

What is the sum of the interior angles of a regular polygon with 9 sides?

1,260°
1,620°
1,800°
1,980°

Answers

The sum of the interior angles of a regular polygon with 9 sides will be 1260°. The correct option is A.

What is the angle of the polygons?

An angle is defined in mathematics as the figure formed by joining two rays at their common endpoint. An interior angle is an angle that exists within a shape. Polygons are closed shapes with sides and vertices. All of the interior angles of a regular polygon are equal.

Given that the number of the sides of the polygon is 9. The sum of the interior angles of the polygons will be calculated as,

Sum = ( n - 2 ) 180°

Sum = ( 9 - 2 ) 180

Sum = 7 x 180

Sum = 1260°

The number of new contributors to a public radio station's annual fund drive over the last ten years is ​63, 58, 61, 72, 98, 103, 121, 147, 163, 198 Using Microsoft Excel, develop a linear regression model that predicts the number of new contributors. Explain the slope of this model. Based on this model, how many new contributors would you predict for the following year?

Answers

Answer:

The number of potential members predicted in next year's estimate becomes 193. The further explanation is given below.

Step-by-step explanation:

The slope of the model,

m = 15.345

c = 24

After comparing with the equation,

⇒  \(y=mx+c\)

we get,

⇒     \(=15.345x + 24\)

The slope seems to be a positive value which also means that another always improves this as component decreases. Which ensures that perhaps the number of contributors rising as time went by.

What is the Pythagorean Theorem?

The Pythagorean Theorem states that in the case of a right triangle, the square of the length of the hypotenuse, which is the longest side,  is equals to the sum of the squares of the lengths of the other two sides.

Hence the equation for the theorem is given as follows:

c² = a² + b².

In which:

c > a and c > b is the length of the hypotenuse.a and b are the lengths of the other two sides (the legs) of the right-angled triangle.

For the triangle in this problem, we have that:

The sides are d ft and 90 ft.The hypotenuse is of 409 ft.

Hence the distance is obtained as follows:

d² + 90² = 409²

\(d = \sqrt{409^2 - 90^2}\)

d = 399 ft.

What are the new coordinates if the figure were rotated 90 degrees counterclockwise

What are the new coordinates if the figure were rotated 90 degrees counterclockwise

Answers

Answer:

third option

Step-by-step explanation:

under a counterclockwise rotation of 90° about the origin

a point (x, y ) → (y, - x )

Then

A (- 1, - 2 ) → (- 2, - (- 1) ) → (- 2, 1 )

B (2, - 2 ) → (- 2, - 2 )

C (1, - 4 ) → (- 4, - 1 )

The new coordinates are (d) A = (2, -1) B = (2, 2) and C = (4, 1)

How to determine the new coordinates rotating by 90 degrees counterclockwise

From the question, we have the following parameters that can be used in our computation:

The figure,

Where, we have

A = (-1, -2)

B = (2, -2)

C = (1, -4)

The rule of 90 degrees counterclockwise is

(x, y) = (-y, x)

Using the above as a guide, we have the following:

A = (2, -1)

B = (2, 2)

C = (4, 1)

Hence, the new coordinates are (d) A = (2, -1) B = (2, 2) and C = (4, 1)

A wire is 71cm long . you wish to cut it into two pieces. One piece is bent into shape of triangle with legs of equal length .The piece is to be bent into shape of circle .

Answers

To solve this problem, we need to find the lengths of the two pieces when the wire is cut into two parts. Let's denote the length of each leg of the triangle as\(\(x\).\)

The perimeter of the triangle is the sum of the lengths of its three sides. Since the two legs are equal in length, the perimeter can be expressed as \(\(2x + x = 3x\).\)

The length of the wire is given as 71 cm, so we have the equation \(\(3x = 71\).\)

Solving for\(\(x\),\) we divide both sides of the equation by 3:

\(\(x = \frac{71}{3}\).\)

Now that we know the length of each leg of the triangle, we can proceed to the next part of the problem.

The circumference of a circle is given by the formula \(\(C = 2\pi r\)\), where\(\(C\)\)is the circumference and r is the radius. In this case, the wire of length xis bent into the shape of a circle, so we can set the circumference equal to x and solve for the radius r:

\(\(x = 2\pi r\).\)

Substituting the value of x we found earlier, we have:

\(\(\frac{71}{3} = 2\pi r\).\)

Solving for r, we divide both sides of the equation by \(\(2\pi\):\)

\(\(r = \frac{71}{6\pi}\).\)

Therefore, the two pieces of wire will have lengths\(\(\frac{71}{3}\)\)cm and the radius of the circle will be\(\(\frac{71}{6\pi}\)\) cm.

In summary, when the 71 cm wire is cut into two pieces, one piece will have a length o\(\(\frac{71}{3}\)\)cm, which can be bent into the shape of an equilateral triangle with legs of equal length, and the other piece can be bent into the shape of a circle with a radius of \(\(\frac{71}{6\pi}\)\) cm.
