Answers

Answer:

Step-by-step explanation: First, you need to write all your data down from least to greatest. Next, count up all the numbers to see how many students. Then you want to find the mean which is average (add then divide). Median is the middle so you will x each number out till you get to the middle, and if the middle is 2 numbers, you find the average of them to find the median. Mode means most often. Range is highest minus lowest. And you can do the next 2.

Answer:

Range: 7

Greater than 9 is: 7

I'm not really sure about the distribution

Total Student: 25

Use the equation y = 2x -5 to find y when x = 3z.


Enter your answer without spaces.

Answers

y=2(3z)-5
y=6z-5

Substitute x with 3z.

Answer:

y = 6z - 5

Step-by-step explanation:

Start with the given function y = 2x -5.  Substitute the given 3z for x:

y = 2(3z) -5

Simplify this through multiplication:

y = 6z - 5

What is the simplified slope for (3,2) and (5,12)

Answers

To find Y intercept
You do y2-y1/ x2-x1
Your y2 is 12, y1 is 2
Your x2 is 2 , x1 is 3
So 12-3/2-3
12-3 is 9
2-3=-1
9/-1 is -9
So your slope is -9

Answer:

-5

Step-by-step explanation:

Recall that slope = rise/run.

Here the change in y (the rise) is -10 (y changes from +12 to +2), and the  change in x (the run) is 2, since x increases from 3 to 5).

The slope of the line through these points is m = rise / run = -10/2 = -5

Answers

Answer: 1300 cm^3, 850 cm^2

Step-by-step explanation:

With a triangular prism, you need to calculate the surface area of the triangle first and then the length. Here's how to solve for the volume (A):

Triangles is b*h/2, plug in the equation

10*13/2

130/2

65

Now use the length of the rest of the shape, which is 20 cm.

65*20=1300

the volume is 1300 cm^3.

for B, finding the surface area requires you to analyze each individual part of the shape.

Each part colored in represents a different shape:

Red:

10*20=200

Blue:

13*10/2=65

65*2=130 (Two triangles)

Green:

13*20=260

260*2=520 (Two rectangles)

Add them all up together.

200+130+520= 850 cm^2

The net of a square pyramid is shown below. What are the possible areas for a single face in this net? Check all that apply.

A net with a square base with sides lengths of 5 meters, and 4 triangles with heights of 6 meters.
11 square meters
15 square meters
24 square meters
25 square meters
30 square meters

Answers

Answer: 1,2,and 4. I did it online and got it right!

Answer:

B. 15 square meters (for the triangles)

D. 25 square meters (for the square base)

Bonus: The total surface area would be 85 square meters.

Step-by-step explanation:

The square base is easier to deduce here; simply square 5 to get 25 square meters for the base.

The triangles require some math, however. But it is relatively simple

(5 * 6)/2

30/2

15 square meters for the triangles.

For bonus, I'll find the total surface area.

5² + 4((5 * 6)/2)

First, square 5 to get 25.

25 + 4((5 * 6)/2)

Now multiply 5 * 6 to get 30.

25 + 4(30/2)

Then divide 30 by 2 to get 15.

25 + 4(15)

Now multiply 4 by 15 to get 60.

25 + 60

Lastly, add 25 and 60 to get 85.

The entire square pyramid's surface area is 85 square meters.
