Step-by-step explanation:

The question is incomplete, as the required data to answer the question are missing.

However, the interpretation of the question is to determine the interquartile range (IQR) of a certain dataset.

Then get the difference between the calculated IQR & Joe's data and also the difference between the calculated IQR & Sam's data

Then, make comparison

To do this, I will use the following assumed datasets.

[tex]Data: 62, 63, 64, 64, 70, 72, 76, 77, 81, 81[/tex]

IQR is calculated as:

[tex]IQR = Q_3 - Q_1[/tex]

[tex]Q_3[/tex] is [tex]the\ median[/tex] of the upper half

[tex]Q_1[/tex] is [tex]the\ median[/tex] of the lower half

For Joe, we have:

[tex]Lower\ half: 62, 63, 64, 64, 70[/tex]

[tex]Upper\ half: 72, 76, 77, 81, 81[/tex]

The median is then calculated as:

[tex]M = \frac{N + 1}{2}[/tex]

For, the lower half:

[tex]Q_1 = \frac{5 + 1}{2} = \frac{6}{2} = 3rd[/tex]

So:

[tex]Q_1 = 64[/tex]

For the upper half:

[tex]Q_3 = \frac{5 + 1}{2} = \frac{6}{2} = 3rd[/tex]

So:

[tex]Q_3 = 77[/tex]

When the same process is applied to Sam's data,

[tex]Q_1 = 52[/tex]

[tex]Q_3 = 58[/tex]

[tex]IQR = Q_3 - Q_1[/tex]

[tex]IQR = 77 - 64[/tex]

[tex]IQR = 13[/tex]

Assume that:

[tex]Joe = 60[/tex]

[tex]Sam = 65[/tex]

[tex]Joe - IQR = 60 - 13 = 47[/tex]

[tex]Sam- IQR = 65- 13 = 52[/tex]

Hence, the IQR is 47 points less for Joe's data than Sam's

Answer:

9

Step-by-step explanation:

Answer:

Step-by-step explanation:

You would first have to plug in for x, (which is already given). After plugging in for x, you would need to solve the equation to get y.

Once you have both x and y, you will have your (x,y)

For example: (given x value = -5)

[tex]f(x) = -|x - 5| -4\\f(-5) = -|(-5) - 5| - 4\\f(-5) = -|-10| - 4\\f(-5) = -10 - 4\\f(-5) = -14\\f(-5) = y = -14\\\\[/tex]

so:

x = -5

y = -14

( -5, -14)

Answer:

11. B

12. C

Step-by-step explanation:

11. The x-axis number cannot have repeating numbers for it to be a function. The y-axis can have repeating numbers.

12. The graph on C passes the vertical line test, thus it's a function.

Answer:

Yes

Step-by-step explanation:

the sign is a less then or equal to sign therefore, p is less then or equal to seven so anything seven and below is possible.

Answer:

Cada parcela tendrá una extensión de 150 metros cuadrados.

Step-by-step explanation:

De acuerdo con el enunciado el huerto escolar tiene una extensión de 4 decámetros y 500 metros cuadrados.

Tengamos presente que un decámetro es igual a 100 metros cuadrados, entonces el huerto escolar tiene un área total de 900 metros cuadrados. Si dividimos esa área en seis parcelas de igual extensión, tenemos que:

[tex]x = \frac{900\,m^{2}}{6}[/tex]

[tex]x = 150\,m^{2}[/tex]

Cada parcela tendrá una extensión de 150 metros cuadrados.

Step-by-step explanation:

Let label this using a triangle.

We are sitting 300 ft away from the building.

We can look up to see the top of building at an angle of 60 degrees. So 60 degrees would be near where we standing at. The other angle of the top triangle would be 30 since that the height of building and the ground horizon is perpendicular to each other so they measure 90 degrees. Using triangle interior theorem, the missing angle would be 30.

We use another triangle since we are looking down.

The height of building and where we sitting at is perpendicular. The angle near we at would measure 15 and the missing angle would be 75.

The triangles both combine to form one triangle. They would form a isoceles triangle.

The most bottom angle of the triangles measure 75 while the angle where we are at of both triangle measure 75. so we have a isoceles triangle.

This means that the hypotenuse of the top triangle is equal to the length of the building.

To find the hypotenuse use 30-60-90 rules,

hypotenuse =twice of most shortest side.

[tex]h = 300 \times 2[/tex]

[tex]h = 600[/tex]

So the length of the building is 600.

Answer:

57 R 3

Step-by-step explanation:

6 goes into 34 5 times with 4 extra, pull down the 5, and 6 goes into 45 7 times with 3 extra. So the answer is 57 R 3.

Answer:

The surface area of the rectangular prism is [tex]160in^2[/tex].

Step-by-step explanation:

The surface area of a 3-dimensional shape is found by adding the area of each side of the shape together. In this case, the areas of each side of the rectangular prism are 20 in, 20 in, 50 in, 50 in, 10 in, and 10 in. Find the surface area by adding each area together and you'll get [tex](50*2)+(20*2)+(10*2)=100+40+20=160in^2[/tex].

Answer:

The answer would be 160 .

Answer:

-89

Step-by-step explanation:

-89

-89= 10(-7) - 19   ----------->  -70 - 19

There were 18 one point shots and 37 two point shots.

Step-by-step explanation:

Let the number of one point shots be x and the number of two point shots be y .

So we have the system:

x + y = 55

x + 2y = 92

Subtract the first equation from the second, we get:

0 + y = 92 - 55 = 37.  

y = 37.

From equation 1 we have x = 55 - y

therefore x = 55 - 37 = 18.
