Answer :
Given that : a car salesperson sells cars at prices ranging from $5,000 to $45,000.
So, The least price = $5000
The largest price = $45000
Therefore, The correct option is B. $25000
Now, we need to state what the distribution exhibits
From the graph we can see at the both sides of the median the graph is similar on the either side.
⇒ The graph is symmetrical about the median.
Hence, The distribution exhibits symmetry.
Therefore, The correct option is C. Symmetry
Answer: the correct answer is $25,000 (b)
&
The Second answer is symmetry (c)

u need two equations.x + y = 125
0.60x + 0.30y = (0.36)(125)
x + y = 125
0.60x + 0.30y = 45
solve for a variable in the first equation
y = 125 - x
plug into the second equation
0.60x + 0.30(125 - x) = 45
0.60x + 37.5 - 0.30x= 45
0.30x + 37.5 = 45
0.30x = 7.5
x = 25
plug the answer for x into the first equation
25 + y = 125
y = 100

The triangle inequality theorem is an important part of geometry in order to mention the dimension of the sides of a triangle clearly.
What is triangle inequality theorem?
The triangle inequality theorem states that, the sum of the length of two sides must be greater than the length of the third side of that triangle.
Here, three sides of this triangle ABC are AB, BC, and CA.
Therefore, as per the triangle inequality theorem:
(Length of AB + length of BC) must be greater than the length of CA.
Therefore, (AB + BC) > CA.
(Length of BC + length of CA) must be greater than the length of AB.
Therefore, (BC + CA) > AB.
(Length of AB + length of CA) must be greater than the length of BC.
Therefore, (AB + CA) > BC
For an example, if we are running in a triangular shaped track, then it can be easily understandable.
Now, if we start running from the point A, then to reach the point B the shortest path will be the straight line AB.
Instead of that, if we go to the C point at first and then reach the point B, then we will travel more distance.
Similarly, starting from the other points, we will get the same results.

Answer:
79
Step-by-step explanation:
Since the triangles are similar, the sides that are the same length have angles that are the same size at the top.
We are given that these two are congruent in the text. We have two identical elements so far — angle of 35 and the side opposite the angle of 35 (which is what the little line in the middle means) — but we are missing that angle G.
Since angle G in the second triangle is in the same place as the angle of 79 in the first one (between the side with the line in it and the angle of 35), we know that angle will be also 79, given that the triangles are congruent (or identical, in other words). So your answer is 79°.

We need to express the ksp expression of C2D3
C2D3

Then set that equation equal to your solubility constant
9.14x10-9 = 108x5
x = 9.67x10-3
So the molar solubility is 9.67x10-3
