Answer:

2.5

Step-by-step explanation:

lower quartile.

3, 4, 5, 5, 6, 6, 7, 7, 8

median = 6

lower quartile 1/4th position

(4+5)/2 = 4.5

Upper quartile 3/4th position

(7+7)/2 = 7

Interquartile range = upper quartile - lower quartile

                                = 7 - 4.5

                                 = 2.5

Answer:

Interquartile range = Q3 - Q1 = 7 - 4.5 = 2.5

Step-by-step explanation:

Before we calculate interquartile range, you should understand that:

Interquartile range is the range between Q3 and Q1 of a dataset i.e Q3 - Q1

Where,

Q1 is the middle value in the first half of the data set and

Q3 is the middle value in the second half of the data set.

So to calculate the interquartile range we find the Q3 and Q1

5, 6, 7, 3, 4, 5, 6, 8, 7

So in the data set to find Q1 and Q3, we rearrange the dataset and divide it into First half and second half.

3, 4, 5, 5, 6, 6, 7, 7, 8

First half = 3, 4, 5, 5

Second half = 6, 7, 7, 8

So

Q1 = (4+5)/2 = 4.5

Q3 = (7+7)/2 = 7

Interquartile range = Q3 - Q1 = 7 - 4.5 = 2.5

Answer: it will take 1.25 hours

Step-by-step explanation:

It

It will take the teacher 1.25 hours to print 6,000 pages.

To calculate how long it will take to print 6,000 pages with a copy machine that can print 80 sheets per minute, we need to divide the total number of pages by the rate of printing per minute to find out the time in minutes, and then convert that time into hours if necessary.

Step 1: Divide the total number of pages by the printing speed to find the time in minutes.

Total pages: 6,000

Printing speed: 80 pages/minute

Time calculation: 6,000 pages divided by 80 pages/minute = 75 minutes

Step 2: Convert minutes into hours by dividing by 60 since there are 60 minutes in an hour.

Conversion to hours: 75 minutes divided by 60 minutes/hour = 1.25 hours

Therefore, it will take the teacher 1.25 hours to print 6,000 pages.

Combine like terms:

3x² - 4x² - 2x + 5x + 6 + 9

-x² + 3x + 15

Final answer:

To simplify the polynomial, combine like terms by adding or subtracting coefficients of terms with the same variable and exponent. The terms simplify to -x^2 + 3x + 15, matching option A.

Explanation:

The subject of the student's question involves simplifying a polynomial. To simplify the given polynomial 3x2 + 6 - 2x + 5x - 4x2 + 9, we need to combine like terms. This process involves adding or subtracting the coefficients of terms with the same variable and exponent. Let's go through the steps:

Combine the terms with x2: 3x2 - 4x2 = -1x2

Combine the terms with x: -2x + 5x = 3x

Add the constant terms: 6 + 9 = 15

Putting it all together, the simplified form of the polynomial is -x2 + 3x + 15, which matches option A.

Remember, when simplifying polynomials, always look for like terms that can be combined and ensure the final expression is written in standard form, with terms ordered from highest to lowest degree.

Answer:

30 mph

Step-by-step explanation:

The average speed = Total distance / Total Time

Distance at 45 m/hr.

t = 20 minutes = 20/60 = 1/3 hour.

r = rate = 45 miles / hour

d = r * t

d = 45 * 1/3 = 15 miles.

Average Speed going home.

t =  30 minutes

t = 30 min / 60 min // hour = 1/2 hours

r = 15 miles / 1/2 = 15 * 2 =  30 miles / hr.

[tex]\sigma ^ 2 = 2.25[/tex]

Step-by-step explanation:

The number of faces obtained by flipping the coin 9 times is a discrete random variable.

If we call this variable x, then, the probability of obtaining a face in each test is p.

Where [tex]p = 0.5[/tex]

If we call n the number of trials then:

[tex]n = 9[/tex]

The distribution of this variable is binomial with parameters

[tex]p = 0.5\\\\n = 9[/tex]

For a binomial distribution, the variance "[tex]\sigma^2[/tex]" is defined as

[tex]\sigma ^ 2 = np(1-p)[/tex]

[tex]\sigma ^ 2 = 9(0.5)(1-0.5)[/tex]

[tex]\sigma ^ 2 = 9(0.5)(0.5)[/tex]

[tex]\sigma ^ 2 = 2.25[/tex]

Given that the volume of a rectangular prism is length x width x height, this problem can be solved by setting up the equation 2w * w * 8 = 400, where w is the width and 2w is the length. Solving this equation, we find that the width is 5 feet and the length is 10 feet.

In mathematics, the volume of a rectangular prism is given by the formula length x width x height. We are given that the volume of the storage container is 400 cubic feet, its height is 8 feet, and the length is twice the width. Let us denote the width as w, then the length is 2w.

From the given volume formula, we have:

Length x Width x Height = Volume

Substituting the values, we get:

2w * w * 8 = 400

Solving this equation, we find:

w^2 = 25

Taking the square root of both sides, we get:

w = 5

Substituting w=5 into 2w, we find the length:

Length = 2*5 = 10

So the width of the container is 5 feet and the length is 10 feet.

Here is what i figured out.

Answer:

First, to find the median, we have to order all numbers, from least to highest:

Now, we calculate the position of each quartile:

[tex]Q_{k}=\frac{k(n+1)}{4}\\Q_{1}=\frac{1(15+1)}{4}=4\\Q_{2}=\frac{2(15+1)}{4}=8\\Q_{3}=\frac{3(15+1)}{4}=12[/tex]

So, the first quartile is in the fourth position, the thirds quartile is in the twelfth position:

So, first quartile is 6.1. Second quartile is 14.6, and the third quartile is 27.1.

It's important to remember that the second quartile is the median. So the median is 14.6

Lastly, the interquartile range is the difference between the third and first quartile. So:

[tex]Q_{3}-Q_{1}=27.1-6.1=21[/tex]

Therefore, the interquartile range is 21.

Max walks 0.2 laps per minute around the track. This conclusion was reached by dividing the total number of laps (6) by the total number of minutes (30).

The Mathematics problem posed is one concerning rates. It is given that Max walks 6 laps in 30 minutes. We need to find out how many laps would Max be able to walk in 1 minute.

To do this, we divide the total number of laps walked by the total number of minutes. In this case, we would divide 6 laps by 30 minutes.

6 laps ÷ 30 minutes = 0.2 laps per minute

Therefore, Max walks 0.2 laps around the track in 1 minute.

Answer:

the radius of sphere X is 2 times larger than the radius of sphere T

Step-by-step explanation:

Given

Surface area of sphere, T =452.16

Surface area of sphere, X= 1808.64

how many times larger is the radius of sphere X than the radius of sphere T?

Finding radius of both spheres:

Surface area of sphere is given as

A=4πr^2

Now putting value of Ta=452.16 in above formula

452.16=4πrt^2

rt^2=452.16/4π

rt^2=35.98

Taking square root on both sides

rt=5.99

Now putting value of Xa=1808.64 in above formula

1808.64=4πrx^2

rx^2=1808.64/4π

rx^2=143.92

Taking square root on both sides

rx=11.99

Comparing radius of sphere X and the radius of sphere T

rx/rt=11.99/5.99

      = 2.00

rx=2(rt)

Hence the radius of sphere X is 2 times larger than the radius of sphere T!

The answer is:

The radius of the  sphere X is 2 times larger than the radius of the sphere T

To solve the problem, we need to find the radius of both spheres using the following formula:

[tex]Area=\pi *radius^{2}\\\\radius=\sqrt{ \frac{Area}{\pi }}[/tex]

Where,

Area, is the area of the circle.

r, is the radius of the circle.

So,

We are given:

[tex]T_{area}=452.16units^{2}\\X_{area}=1808.64units^{2}[/tex]

Now, calculating we have:

For the sphere X,

[tex]X_{radius}=\sqrt{ \frac{X_{area}}{\pi }}=\sqrt{\frac{1808.64units^{2} }{\pi } }\\\\X_{radius}=\sqrt{\frac{1808.64units^{2} }{\pi }}=\sqrt{575.71units^{2} }=23.99units[/tex]

For the sphere T,

[tex]T_{radius}=\sqrt{ \frac{T_{area}}{\pi }}=\sqrt{\frac{452.16units^{2} }{\pi } }\\\\X_{radius}=\sqrt{\frac{452.16units^{2} }{\pi }}=\sqrt{143.93units^{2} }=11.99units[/tex]

Then, dividing the radius of the X sphere by the  T sphere to know the ratio (between their radius), we have:

[tex]ratio=\frac{23.99units}{11.99units}=2[/tex]

Hence, we have the radius of the sphere X is 2 times larger than the radius of the sphere T.

Final answer:

The function f(x) = 4(2)^(-x) - 3 approaches -3 as x approaches infinity and decreases without bound as x approaches negative infinity, with a horizontal asymptote at y = -3.

Explanation:

The end behavior of a function describes what happens to the function's values as x approaches infinity or negative infinity. For the function f(x) = 4(2)^(-x) - 3, as x approaches infinity, the term 2^(-x) approaches zero, because any non-zero base raised to the power of negative infinity is zero. Thus, the function approaches -3. Conversely, as x approaches negative infinity, the term 2^(-x) grows exponentially, and the function's values decrease without bound, heading towards negative infinity. However, since f(x) involves a negative exponential function, the graph ultimately will approach the horizontal asymptote y = -3.

Answer:

y = 3x² - 6x - 72

Step-by-step explanation:

Since the roots are x = - 4 and x = 6 then the factors are

(x + 4) and (x - 6) and the quadratic function is

y = a(x + 4)(x - 6) ← a is a multiplier, in this case 3, so

y = 3(x + 4)(x - 6) ← expand factors and distribute by 3

y = 3(x² - 2x - 24)

y = 3x² - 6x - 72

3x²-6x-72. The quadratic equation whose  roots are -4 and 6 with a leading coefficient of 3 is 3x²-6x-72.

The solutions of a quadratic equation are x = -4 and x = 6 with a leading coefficient of 3. The solutions are two real numbers which means that (x + 4) and (x - 6) are the factors of our unknown quadratic equation and the leading coefficient is 3.

[tex]3(x+4)(x-6)=0[/tex]

Expand (x+4)(x-6):

[tex]3(x^{2} -2x-24)=0\\3x^{2} -6x-72=0[/tex] which is our quadratic equation.

The sum of the angles that do not measure 22 degrees is equal to 316°

Step-by-step explanation:

The question in English is

A rhombus has a 22-degree angle. How much is the sum of its angles that do not measure 22 degrees worth?

we know that

The opposite internal angles of a rhombus are equal and the adjacent internal angles are supplementary

so

Let

x -----> the measure of an adjacent angle to 22 degrees in the rhombus

x+22°=180°

x=180°-22°=158°

therefore

The sum of the angles that do not measure 22 degrees is equal to

158°+158°=316°
