Answer: NO
Step-by-step explanation:
This is because if you think about it, only the people that want to do the survey do it. Those who dont want to do it dont have to. This makes it voluntary. Any time the surveyed person gets to choose if they can do it it is voluntary. Furthermore, If it is voluntary it can usually represent all of the different peoples. But in this case, the shy people dont get a say because they would choose to not survey. So the shy people would not be represented. That is why this isn't random.

Help me I am a stone when it comes to absolute value in problems—
Explination too please
Answer:
31.) you put a dot on one and go to the right
32.) you put a dot on ten and go to the left
Step-by-step explanation:
the absolute value part is honestly just to throw u off, it also helps if you read it aloud. so for example in # 31. is saying the absolute value of b minus 5 is greater or equal to 1, you could also think of it as any number is greater or equal to one. hope that helps!
when dealing with an absolute value expression, let's keep in mind that the expression once we remove the bars it has a ± version, so if the expression were say hmmm |a + b| = 25, if we remove the bars we really have a duet, namely ±(a + b) = 25, same if we had |a + b| > 25, then ±(a + b) > 25.
Tis noteworthy, that unlike "equalities", inequalities vary mainly on that, when we divide or multiply or exponentialize by a negative value, the inequality sign does a horizontal flip, it changes, so let's proceed
[tex]\boxed{31}\\\\ |b-5|\geqslant 1\implies \pm(b-5)\geqslant 1\implies \begin{cases} +(b-5)\geqslant 1\\ b\geqslant 6\\[-0.5em] \hrulefill\\ -(b-5)\geqslant 1\\ b-5\stackrel{\stackrel{notice}{\downarrow }}{\leqslant} -1\\ b \leqslant 4 \end{cases}~\hfill 6~~\leqslant ~~ b~~\leqslant ~~4[/tex]
[tex]\boxed{32}\\\\ |-2r|\leqslant 10\implies \pm(-2r)\leqslant 10\implies \begin{cases} +(-2r)\leqslant 10\\ -2r\leqslant 10\\ r\stackrel{\stackrel{notice}{\downarrow }}{\geqslant} \cfrac{10}{-2}\\\\ r\geqslant -5\\[-0.5em] \hrulefill\\ -(-2r) \leqslant 10\\ 2r \leqslant 10\\ r\leqslant \cfrac{10}{2}\\\\ r \leqslant 5 \end{cases}~\hfill -5~~\leqslant~~ r ~~\leqslant~~5[/tex]

. Diego received and spent money in the following ways last week.
For each example, write a positive or negative number to represent the change in money from his perspective.
i. He earned $30 dollars by cutting the neighbor’s lawn.
a
ii. He spent $14 going to the movies.
a
iii. He spent $3.55 on an ice cream cone.
a
b. What does 0 mean in this situation?
Type your response in the space below.
Answer:
earned $30 means +30
spent $14 means -14 (he used the money to buy something meaning he loses some money)
spent $3.55 means -3.55 (again, he uses some money to buy something which means he loses this amount of money)
In this situation 0 means he either didnt gain/earn money or he spent all his money.

7 Points: What is the volume of this rectangular pyramid?
_______ cubic yards
Answer:
25 cubic yardsStep-by-step explanation:
[tex]\large\text{volume of a rectangular pyramid} =\frac{1}{3} \times \text{base} \times \text{height}[/tex]
[tex]=\frac{1}{3} \times \left( 5\times 5\right) \times 3[/tex]
[tex]=\frac{1}{3} \times \left( 25\right) \times 3[/tex]
[tex]=\frac{1}{3} \times \left( 75\right) =\frac{75}{3} =25[/tex]
Answer:
5 yards
Step-by-step explanation:
The volume V of a pyramid is one-third the area of the base B times the height h .
[tex]volume \: = \frac{1}{3} \times base \times height[/tex]
[tex] \frac{1}{3} \times 5 \times 3 = 5yards[/tex]

write an expression to represent the area of the flag as the product of the flags length and width
Answer:
A = l * w
Step-by-step explanation:
the length times width would be the area, so just make variables of each thing and then you are good! It would be important to note any more information that is given, like the ratio of the length and the width, in which case just add the respective coefficients based on the ratio (e.g 3:2 would mean 3l * 2w = A). Hope this helps!

b) Your sister says that the angles ∠DCA and ∠BCA are supplementary angles. Is she correct? Explain your reasoning. (1 point)
c) Is triangle DCA congruent to triangle BCA? Explain. (2 points)
Answer:
B) No, supplementary angles are either of two angles whose sum is 180 degrees.
C) Yes, the triangles are congruent because the triangles have exactly the same size and shape
Step-by-step explanation:
B) From the image below an 180 degree angle would be obtuse in which neither angle appears to be so they are not supplementary.
C) They are congruent because they are taking angles of the same angles as one another just on different sides of the shape.

Peyton and James each bought a large cookie cake. The cookie cakes are
the same size.
Peyton cut his cookie cake into 12 slices.
James cut his cookie cake into 6 slices and ate 4 slices.
Together Peyton and James ate 10
12 of one cookie cake.
How many slices of cake did Peyton eat?
A 1 slice
B 2 slices
C 3 slices
D 4 slices
Answer:
2 slices.
Step-by-step explanation:
Let's say that James' cake is essentially one half of Peyton's cake. 6 x 2 is 12, and 4 x 2 is 8. So James' must have eaten 8 slices while Peyton ate 2.
