The median/middle is 5 and the minimum is 0 and the maximum is 11. The first quartile is 7/5= 1.4 and the second is 4/2 = 2

Step-by-step explanation:

The five number summary for the data set 0,2,2,4,5,5,5,5,7,11 is as minimum value is 0, maximum value is 11, median is 5, first quartile is 2 and second quartile is 5.

The five number summary for the data set provides the basic information of a data set. This consist of minimum value, maximum value, median, first quartile, and second quartile.

The provided data set is,

0,2,2,4,5,5,5,5,7,11

The data is arranged in the increasing order. The minimum value in this number is 0 while the maximum number is 11.

As the middle value of the data is 5. Thus, the median of this number is,

[tex]m=5[/tex]

The first quartile is the median in the lower half of the data. In this data lower half consist 0,2,2,4,5 which has the median or first quartile as,

[tex]Q_1=2[/tex]

Answer:

Graph it as ○--->

The open circle because the answer is greater than 8 and we are going to the left because it is greater than.

Answer:

No, it will not change

Step-by-step explanation:

Because the size of the tank is not a factor that can be used to find the rate of change. The rate of change will continue to be 30 gallons per minute.

The average rate of change of gallons per minute is 30 gallons per minute.

No, the average rate of change of gallons per minute will not change even if the size of the tank is doubled because the size of the tank is not used to find the average rate of change.

The coordinates in a graph indicate the location of a point with respect to the x-axis and y-axis.

The coordinates in a graph show the relationship between the information plotted on the given x-axis and y-axis.

We have,

From the graph,

Two coordinates to find the average rate of change in gallons per minute.

(1, 30) and (3, 90).

These coordinates represent a change in the amount of water in the given unit of time.

x-coordinates is the time.

y-coordinate is the amount of water.

Now,

The average rate of change of gallons per minute:

(1, 30) = (a, b) and (3, 90) = (c, d)

= d - b / c - a

= 90 - 30 / 3 - 1

= 60 / 2

= 30

Thus

The average rate of change of gallons per minute is 30 gallons per minute.

No, the average rate of change of gallons per minute will not change even if the size of the tank is doubled because the size of the tank is not used to find the average rate of change.

Answer:

22km= 2 hours and 45 mins

To find speed: Distance/Time

22/2.75 = 8

Your answer 8km/h

Step-by-step explanation: When finding speed, the formula is always distance divided by time. 45 minutes of 60 minutes is 3/4 of an hour, and 3/4 is 0.75 is decimal. So you add the 2 + .75, and you'll get 2.75. After you convert the time, you begin dividing and you'll get your answer!

Answer:

[tex]\frac{n^{2}}{2a}[/tex]

Step-by-step explanation:

Answer:

(n^2)/2a

Step-by-step explanation:

We'll take this in small steps. Don't worry and follow along if you wish :D

Where do we start? Well, first, we notice that all of the numbers/variables (on both the denominator and the numerator) are multiplied by each other. If this case had addition or subtraction in the fraction, the explanation would have differed.

Let's take on a simpler example to show you what I mean. Here's a relatively simpler equation with no pesky variables:

(1 + 3)/4

This equation has to be broken down like this:

1/4 + 3/4

And although we could just do (1 + 3) quickly and divide by 4, consider it if we replace them with numbers instead, or variables in other words:

(x + y)/x

Then, it would work the same way as the previous example:

x/x + y/x

And that would further simplify to (1 + y/x).

But, we're lucky! Because there is no addition or subtraction, we won't have to divide all the numbers that are in the numerator with the number(s) in the denominator. Consider this:

(3*4)/4

We only need to divide 4 by the denominator (which is also four, in this case) and not both 3 and 4 like how we would solve if it had addition or subtraction.

First step! Let's take all of the variables out of this nasty equation we have on our hands to make it simpler:

(9an^3)/(18a^2n)

We would be left with...

9/18

And then we would reduce to leave 1/2. Notice that if we add all the variables back, we would have:

(1an^3)/(2a^2n)

Or (an^3)/(2a^2n)

If we write it out, we'll find this equation a tad bit easier with the large numbers dealt with (although I will admit, it doesn't look that great on the screen—lol)!

Back to business. Here, we need to simplify the variables. Given, we have to remember that variables are just your every-day number (but unknown). Because of that, we get to divide them very much like how we would with regular numbers. Rope in some of our previous lesson about not having to divide all the numbers on the numerator from the denominator from the beginning, too!

(an^3)/(2a^2n)

You can cancel out the variable a^ in this equation. That would leave you with:

(n^3)/(2an)

Try to simplify the rest on your own and use my work to check your answers! if you can't, then no worries. Follow along with me :D

We can also reduce using n. That will leave:

(n^2)/2a

And then you're done! I would recommend more questions like these (if you aren't already doing them) because you'll be using simplifying techniques similar to this equation in the future.

Good luck and keep studying!

Answer:

Step-by-step explanation:

Area of the rectangular area = Length * width

A = LW ...... 1

If he wants to have a rectangular area  of turf with length one foot less than 3 times the width, then

L = 3W - 1 ...... 2

Substitute 2 into 1

A = (2W-1)W

A = 2W^2 - W

Since area = 150sq.ft

150 = 2W^2 - W

2W^2 - W - 150 = 0

Factorize

2W^2 - W - 150 = 0

W = 1±√1+4(300)/2(2)

W =  1±√1201/2(2)

W = 1±34.655/4

W = 35.655/4

W = 8.91375

W = 8.9 (to nearest tenth)

Get the length

L = A/W

L = 150/8.9

L = 16.85

L = 16.6ft

Hence the length is 16.6ft and the width is 8.9ft

Answer:

82.5°

Step-by-step explanation:

This is the case of a isosceles triangle , as you may know in a isosceles triangle , there are two sides of equal length as well as two equal angles.

You know that the sum of angles in a triangle is 180°, therefore it comes to this equation :

15° + 2x = 180°

2x = 165°

x = 82.5°

therefore 82.5° is the correct answer.

Based on the HL congruence rule, the value of x, is calculated as:

x = 2.

Both triangles that share the same side and have corresponding angle 90 degrees and a pair of corresponding congruent hypotenuse are congruent  to each other based on the HL congruence theorem.

This means that:

17x - 3 = 9x + 13

Solve for the value of x:

17x - 9x = 3 + 13

8x = 16

Divide both sides by 8:

8x/8 = 16/8

x = 2

Answer:

y = -4/3x - 6

Step-by-step explanation:

1. Find the slope. Since we know that a line perpendicular to another is it's opposite reciprocal, or the product of the two is equal to -1, we can find the slope. -4/3 times 3/4 is -1, so -4/3 would be the slope of this line.

2. Plug in the point and slope into the slope-point equation. The equation would be y - 2 = -4/3 * (x + 6).

3. Simplify. The simplified equation would be y = -4/3x - 6.

Answer: y = -4/3x - 6

Answer:

The amount of water leaking per hour is 3/4 of the bucket volume

Step-by-step explanation:

The given parameters are;

The volume of water in the bucket = 3/10 of the bucket volume

The time duration of the leak = 2/5 hour

Therefore;

The leak rate = Volume/Time

The amount of water leaking per hour = (3/10 of the bucket volume)/(2/5 hour)

The leak rate = The amount of water leaking per hour = 3/4 of the bucket volume/hour.

The amount of water leaking per hour is  [tex]\frac{3}{4}[/tex] of the bucket volume.

Given ;

The volume of water in the bucket =  [tex]\frac{3}{10}[/tex] of the bucket volume

The time duration of the leak =  [tex]\frac{2}{5}[/tex] hour

Therefore;

The leak rate = [tex]\frac{volume }{time}[/tex]

The amount of water leaking per hour = ( [tex]\frac{3}{10}[/tex] 0f the bucket volume)/([tex]\frac{2}{5}[/tex] hour)

                                                                =  ( [tex]\frac{3}{10} . \frac{5}{2}[/tex] ) volume per hour

The leak rate = The amount of water leaking per hour = 3/4 of the bucket volume per hour.
