Put the word “aware” before or after your answer if your gonna send a link. I would like to know if they are bots. (99% sure they are)
Answer:
B (range)
Step-by-step explanation:
The IQR would actually increase, because the Q1, Q2, and Q3 would get most likely larger. (Or possibly stay the same).
The median would most likely increase, possibly stay the same.
The maximu would stay the same.
The range would decrease, because right now it’s 13, so without the outlier, the minimum value would be closer to the rest of the data.
Triangle 2 is a scale drawing of Triangle 1.
Based on the information in the diagram, what is the length of side b?
Answer:
36 would be the answer
Step-by-step explanation:
The length of side b in triangle 2 is 36.
What are similar triangles?Two triangles are similar if they have the same corresponding angles and their corresponding sides are in equal ratios.
Given that, there are two triangles, triangle 2 is a scale drawing of triangle 1.
Therefore, Δ 1~Δ 2,
According to the definition of similar triangles,
6/27 = 10/45 = 8/b
Therefore,
8/b = 6/27
8/b = 2/9
b = 36
Hence, the length of side b in triangle 2 is 36.

Answer:
B. $8,960
Step-by-step explanation:
Use your number sense.
If the account earns interest, the balance will increase from the initial deposit of $8000. The only sensible answer choice is B, $8960.

Fred earns dollars. Chad earns 45% more than Fred which expression represents the amount of money in dollars that chad earns
Answer:
$0.45x
Step-by-step explanation:
Fred earns dollars. Let Fred earns $x.
Chad earns 45% more than Fred.
We need to find the expression for Chad.
Chad amount = 45% of x
[tex]=\dfrac{45}{100}x\\\\=0.45x[/tex]
So, Chad earns $0.45x.
Alvin is 7 years younger than Elgas. The sum of their ages is 63. What is Elgas age?
Answer:
Elgas is 35.
Step-by-step explanation:
Let's set up an equation.
Alvin is 7 years younger than Elgas.
A = E - 7
The sum of their ages is 63.
A + E = 63
Let's use substitution.
Plug in the first equation of A into the second equation.
A + E = 63
(E - 7) + E = 63
Combine like terms.
2E - 7 = 63
Add 7 to both sides.
2E = 70
Divide both sides by 2.
E = 35
Elgas is 35.
Hope this helps!

Answer:
113.1 cm²
Step-by-step explanation:
we are given the diameter of the circle (length is 12 cm), and the formula for the area of the circle, which is πr², where r is the radius
so first, we need to find the radius
the length of the radius is half the length of the diameter
so that means that r=d/2
r=d/2
r=12/2
r=6
therefore the length of the radius is 6
now square 6, which is the same as multiplying it by itself
6²=36
now, multiply the radius squared by π, which is often substituted for as 3.14 or 22/7
so if we were to do 22/7 for instance,
36*22/7≈113.14
round that to 113.1
there's your answer :)
Hope this helps!

Write an explicit formula for an, the n^th term of the sequence 22, 20, 18, ....
Answer:
[tex]a_n=a+(n-1)d[/tex]
Step-by-step explanation:
The given sequence is 22, 20, 18, ...
We need to find the explicit formula for an.
First term is 22
Second term = 20
Third term = 18
We can write the formula as :
[tex]a_n=a+(n-1)d[/tex]
Where
a is 22
d is common difference = 20-22 = -2
Forth term will be :
[tex]a_4=22+(4-1)(-2)\\\\=22-6\\\\=16[/tex]
Hence, the formula is [tex]a_n=a+(n-1)d[/tex].
If X = 9 units, Y = 7 units, Z = 18 units, and h = 8 units, what is the surface area of the triangular prism shown above?
Answer: 506 square units (answer choice B)
Step-by-step explanation:
The formula for the surface area of a triangular prism is:
SA = bh + 2ls + lb,
where b is the base, h is the height, l is the length, and s is the side of the triangle.
In this case, the base is 7 (Y), the height is 8 (h), the length is 18 (Z), and the side of the triangle is 9 (X).
So, by subsituition, we have:
SA = (7)(8) + 2(18)(9) + (18)(7)
SA = 56 + 324 + 126
SA = 506
The surface area is 506 square units.
Hope this helps! :)
