So we want to find the surface area of this pyramid. Finding the surface area of a 3D shape is essentially finding the area of all its sides and adding them together.
What we're going to have to do here is find the area of the base of the pyramid, which is basically a square, and find the area of all four sides of the pyramid, which are triangles.
Formula for area of a square: length × width
Formula for area of a triangle: (base × height) ÷ 2
First we will find the area of the base:
l × w = A
(Write out formula)
8 × 8 =
(Input values)
A = 64 m^2 (square meters or meters squared)
(We have our answer, dont forgot to write your units.)
So we've figured out the area of the base. Now onto the triangles:
(b×h) ÷ 2 = A
(Write out formula)
(8 × 6) ÷ 2 =
(Input values)
48 ÷ 2 =
(Use PEMDAS to solve this correctly. We did whatever was in the parenthesis first, which was multiplication.)
A = 24m^2 (square meters or meters squared)
(We have our answer.)
Now we've found the area of the base of the pyramid and one of the sides of the pyramid, but we're almost done! There's four sides to the pyramid, they're all the same. So since we found the area for one, we can multiply that by 4 to find the area of all sides added together:
24 × 4
(area of a side × total sides)
= 96m^2
All that's left is adding the 96 to the area of the base to get our total surface area of the pyramid:
96 + 64 = 160
The surface area of the pyramid is 160m^2(square meters or meters squared)
(Hope this helps :) )

Answers
Answer:
(a) [tex]5 * (2x - 1) = 10x - 5[/tex]
(b) [tex]6 * x = x + 2x + 3x[/tex]
(c) [tex]\frac{1}{2}(x - 6) = \frac{1}{2}x - 3[/tex]
(d) [tex]y(3x + 4z) = 3xy + 4yz[/tex]
(e) [tex]z(2xy - 3y + 4x) = 2xyz - 3yz + 4xz[/tex]
Step-by-step explanation:
Solving (a):
Given
[tex]10x - 5[/tex]
Required
Express as a product
Express 10x as 5 * 2x
[tex]10x - 5 = 5 * 2x - 5[/tex]
Apply distributive property
[tex]10x - 5 = 5(2x - 1)[/tex]
[tex]10x - 5 = 5 * (2x - 1)[/tex]
So:
[tex]5 * (2x - 1) = 10x - 5[/tex]
Solving (b):
Given
[tex]x + 2x + 3x[/tex]
Required
Express as a product
Express 2x and 3x as 2 * x and 3 * x, respectively
[tex]x + 2x + 3x = x + 2*x + 3*x[/tex]
Apply distributive property
[tex]x + 2x + 3x = x(1 + 2 + 3)[/tex]
[tex]x + 2x + 3x = x(6)[/tex]
[tex]x + 2x + 3x = 6*x[/tex]
So:
[tex]6 * x = x + 2x + 3x[/tex]
Solving (c):
Given
[tex]\frac{1}{2}(x - 6)[/tex]
Required
Express as a sum/difference
Apply distributive property
[tex]\frac{1}{2}(x - 6) = \frac{1}{2}x - \frac{1}{2}*6[/tex]
[tex]\frac{1}{2}(x - 6) = \frac{1}{2}x - \frac{6}{2}[/tex]
[tex]\frac{1}{2}(x - 6) = \frac{1}{2}x - 3[/tex]
Solving (d):
Given
[tex]y(3x + 4z)[/tex]
Required
Express as a sum/difference
Apply distributive property
[tex]y(3x + 4z) = 3x * y + 4z * y[/tex]
[tex]y(3x + 4z) = 3xy + 4yz[/tex]
Solving (e):
Given
[tex]2xyz - 3yz + 4xz[/tex]
Required
Express as a product
Factorize
[tex]2xyz - 3yz + 4xz = 2xy * z - 3y * z + 4x * z[/tex]
Apply distributive property
[tex]2xyz - 3yz + 4xz = z(2xy - 3y + 4x)[/tex]
So:
[tex]z(2xy - 3y + 4x) = 2xyz - 3yz + 4xz[/tex]

Answer:
X-intercepts: (2,0) and (4,0)
Vertex: (3,-1)
Step-by-step explanation:
1) First, let's find the x-intercepts. The x-intercepts are the points at which the graph intersects the x-axis. Look at the x-axis. The x-axis is crossed at two points, (2,0) and (4,0). Therefore, those are the x-intercepts.
2) Now, let's find the vertex. For parabolas, the vertex can either be the lowest point of the graph (the minimum) or the highest point on the graph (the maximum). So, seeing how the graph goes up until infinity, find the lowest point the graph hits. Reading the graph, it would be (3,-1).
Ron randomly pulls a pen out of a box that contains 1 red, 2 black, and 3 blue pens. He does
this 4 times, replacing the pen each time, but pulls out a blue pen only 1 time. Ron concludes
that the observed frequency of pulling a blue pen will eventually be closer to the expected
frequency based on the theoretical probability of pulling a blue pen. Which reasoning best
supports his conclusion?
Answers
Answer: A
Step-by-step explanation:
Ron's conclusion that the observed frequency will eventually be closer to the expected frequency is reasonable and supported by probability theory.
What is Probability?It is a branch of mathematics that deals with the occurrence of a random event.
The law of large numbers states that as the sample size increases, the observed frequency of an event will converge to the expected frequency based on the theoretical probability of the event. In this case, the expected frequency of pulling a blue pen is 3/6 or 1/2, which is based on the theoretical probability of pulling a blue pen.
Although Ron pulled a blue pen only 1 time in 4 trials, it is important to note that he replaced the pen each time.
This means that each trial was independent of the others, and the probability of pulling a blue pen in each trial remained the same at 3/6 or 1/2.
As Ron continues to repeat the trials and increase the sample size, the observed frequency of pulling a blue pen will become closer and closer to the expected frequency of 1/2, as predicted by the law of large numbers.
Therefore, Ron's conclusion that the observed frequency will eventually be closer to the expected frequency is reasonable and supported by probability theory.

Step-by-step explanation:
-3.8x + 7 and c = -75/14 and/or c = -5.35714
Step-by-step explanation:First equation:
1.2x + 7 - 5x =
Step 1 - Group like terms:
1.2 - 5x + 7
Step 2 - Add simliar elements:
1.2 x - 5x = -3.8x =
3.8x + 7
Answer: -3.8x + 7
Second equation:
2.2c - 3 = 2(6 - c) + 7c =
Step 1 - Multiply both sides by 10:
2.2c ⋅ 10-3 ⋅ 10 = 2(6 - c) ⋅ 10 + 7c ⋅ 10
Step 2 - Refine:
22c - 30 = 20(6-c) + 70c =
- Expand 20(6-c): 120 - 20c
22c - 30 = 120 - 20c + 70c
Step 3 - Add similar elements:
-20c + 70c = 50c =
22c - 30 = 120 + 50c
Step 4 - Add 30 to both sides:
22c - 30 + 30 = 120 + 50c + 30
Step 5 - Simplify:
22c = 50c + 150
Step 6 - Subtract 50c from both sides:
22c - 50c = 50c + 150 - 50c
Step 7 - Simplify:
-28c = 150
Step 8 - Divide both sides by -28:
-28c/-28 = 150/-28
Step 9 - Simplify:
c = -75/14
Answer:
Fraction form: c = -75/14
Decimal form: c = -5.35714

A. no association

C. positive linear association

Answers
There is no association between the height and the hand span.
We can only establish an association when there is a consistent rate of increase or decrease between two variables. The increase or decrease is linear when they occur smoothly.
As we can see, we can not establish any particular relationship between the height and the hand span hence we conclude that there is no association between them.
