In order to determine how far the wheel travels, we will have to find the circumference of the wheel. This is expressed as;

Circumference of the wheel = 2πr

r is the radius of the wheel = 9in

Substitute

Circumference of the wheel = 2(3.14)(9)

Circumference of the wheel = 56.52inches

Hence the wheel travels 57inches to the nearest inch

Answer: System 1 has an infinite number of solutions and System II has no solutions.

Step-by-step explanation:

If we look at system 1, we see that if we multiply the first equation by 2 and subtract the y value so that its on the same side as x, the equations are the same. That means that no matter the x or y value, it will be a solution.

If we look at system 2, however, we see that if we multiply the top equation by 3, the equations are the exact same except for the fact that the top equation has a -21. This means that no matter the x or y, there will never be a solution.

Step-by-step explanation:

Use the triangle inequality theorem.

Add two sides together and see if it is greater than the length of the 3rd side:

28 + 41 = 69 which is greater than 13

41 + 13 = 54 which is greater than 28

28 + 13 = 41 this is equal to the 3rd side length of 41 and not greater than 41

Because 28 + 13 is not greater than 41 those 3 lengths cannot make a triangle.

Answer:

  4, -1

Step-by-step explanation:

We can let x and y represent the two numbers. The first relation is ...

  2x + 4y = 4

The second relation is ...

  x - y = 5

Subtracting the second relation from half the first gives ...

  1/2(2x +4y) -(x -y) = 1/2(4) -(5)

  3y = -3

  y = -1

From the second relation, ...

  x = 5 +y = 5 -1 = 4

The two numbers are 4 and -1.

Answer:

the answer is 10

Step-by-step explanation:

The difference between the range and the IQR of the data set represented by the box plot is 10.

An interquartile range is a measure of the difference between the upper and lower quartiles of a dataset.

W can find the values of the upper and lower quartile and median from a box plot.

The middle line is the median and the first line is the lower quartile and the last line is the upper quartile.

The formula used is Upper quartile - Lower quartile.

We have,

The range of a dataset is calculated as the difference between the maximum and minimum values in the dataset.

In this case, the range is:

Range = highest value - lowest value = 34 - 16 = 18

The interquartile range (IQR) is the difference between the third quartile (Q3) and the first quartile (Q1). In this case, the IQR is:

IQR = Q3 - Q1 = 29 - 21 = 8

So the difference between the range and the IQR is:

Range - IQR = 18 - 8 = 10

Therefore,

The difference between the range and the IQR of the data set represented by the box plot is 10.

Answer: x=-1+2

Step-by-step explanation:

Answer:

Step-by-step explanation:

Subtract 2x from both sides of the equation.

X2-1=−2x

Add 1 to both sides of the equation.

X2=−2x+1

Take the square root of both sides of the equation to eliminate the exponent on the left side.

X=±√−2x-1

The complete solution is the result of both the positive and negative portions of the solution.

First, use the positive value of the ± to find the first solution.

X=√−2x+1

Next, use the negative value of the ± to find the second solution.

X=−√−2x+1

The complete solution is the result of both the positive and negative portions of the solution.

X=√−2x+1

X=−√−2x+1

Answer:

y = -3x

Step-by-step explanation:

To get slope intercept, you divide both y values by both x values like this

[tex]\frac{y_2 - y_1}{x_2 - x_1}[/tex]

In this case this will be [tex]\frac{(-3 - 6)}{(1 - (-2))}[/tex]

This will become [tex]\frac{-9}{3}[/tex]

Divide those two to get -3, and now you get your slope intercept.

Answer:

[tex]z=\frac{0.48-0.59}{\sqrt{\frac{0.59(0.41)}{100}}}[/tex]

Step-by-step explanation:

The z score in terms of the null hypothesis and surveyed statistic is in the form [tex]z=\frac{\hat{p}-p_0}{\sqrt{\frac{p_0(1-p_0)}{n}}}[/tex], (similar to [tex]z=\frac{x-\mu}{\sigma}[/tex]) where [tex]p_0[/tex] is the population parameter (in this case, 0.59) and [tex]\hat{p}[/tex] is the statistic (in this case, 0.48). Finally, [tex]n[/tex] is the sample size, 100. Substitute in your values, and you get the above answer.

The test statistic calculation look like in this situation for an appropriate hypothesis test is negative.

A local elementary school claims that 59% of its students bring their own lunch on a daily basis.

The z score in terms of the null hypothesis and surveyed statistic is in the form,

[tex]\frac{P-P_0}{\sqrt{P_0(1-P_0)/n} }[/tex]

where [tex]p_0[/tex] is the population parameter (in this case, 0.59) and P is the statistic (in this case, 0.48)

Finally,  is n the sample size, 100.

Substitute in your values, and you get the above answer,

[tex]Z=\frac{0.40-0.59}{\sqrt{\frac{0.59(0.41}{100} } }\\ \\=-3.8630[/tex]

17) -4y + 16 = 6x

Isolate the variable, y. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.

First, subtract 16 from both sides of the equation:

-4y + 16 (-16) = 6x (-16)

-4y = 6x- 16

Next, divide -4 from both sides of the equation:

(-4y)/-4 = (6x - 16)/-4

y = (6x)/-4 + (-16)/-4

y = -3x/2 + 4

Slope: [tex]-\frac{3}{2}[/tex]

~

18) 0 = -12y -36 + 15x

Isolate the variable, y. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.

First, add 12y to both sides of the equation:

0 (+12y) =  - 12y (+12y) + 15x - 36

12y = 15x - 36

Next, divide 12 from both sides of the equation to isolate the variable, y:

(12y)/12 = (15x - 36)/12

y = (5/4)x - 3

Slope: [tex]\frac{5}{4}[/tex]

~

19) 3x = -6y

Isolate the variable, y. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.

Divide -6 from both sides of the equation:

(3x)/-6 = (-6y)/-6

y = 3x/-6

y = -(3/6)x

Simplify. Divide common factors from both the numerator and denominator.

-(3/6)/(3/3) = - 1/2

Slope: [tex]-\frac{1}{2}[/tex]

~

20) -2x -5 = -5y

Isolate the variable, y. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.

Divide -5 from both sides of the equation:

(-2x - 5)/-5 = (-5y)/-5

y = (-2x - 5)/-5

y = (2/5)x + 1

Slope: [tex]\frac{2}{5}[/tex]
