Which statement is NOT an accurate comparison of the two dot plots?
A) There is a gap from 7 to 11 for Class A and there is no gap for Class B.
B) Class A is clustered around two areas, while Class B is clustered around the center. C) Class A spreads from 4 to 14, while Class B is spread from 3 to 9.
D) The median for both dot plots is 6.
Answer:
D
Step-by-step explanation:
The statement which is not an accurate comparison of the two dot plots is stated as: Option D) The median for both dot plots is 6
What are clusters in data?Clusters are groups in data. Each group is like clustered or grouped around some number, usually the mean of that cluster.
Spread, also called range of a data, tells the difference between the maximum and minimum value of that data, thus showing how much widely is it spread.
Thus, spread = maximum value - minimum value
For this case, we see that there are two clusters for class A and for class B there is only single cluster which is almost separated but not distinctly forming two clusters.
Class A spreads from minimum 4 to maximum 16, thus its spread is 16-4 = 12 units wide.
Class B spreads from minimum 3 to maximum 9, thus, its spread is 9-2 = 6 units wide.
Also, we can see that for class A, there is a gap from 7 to 11.
So all three options A, B and C are correct.
Now, let we find median.
Median is that value which is in mid of ordered (ascending or descending data set).
For class A, we have the data as:
4,4,4,4,4,5,5,5,6,6, 12,13,13,13,14,14
They are total 16 observations. The middle observation pair is 8th and 9th observation, which are 5 and 6
We can take any of the number between 5 and 6, so 5 < median < 6
That means median of class A's data is smaller than 6, thus, not being 6.
Thus, option D is incorrect and we don't need to find median of class B.
Thus, the statement which is not an accurate comparison of the two dot plots is stated as: Option D) The median for both dot plots is 6

find the equation of the line passing through points (-4,2) and (1,-6)
Answer:
y + 6 = (-8/5)(x - 1) in point-slope form
Step-by-step explanation:
Moving from the 1st point to the first, we see that x (the 'run') increases by 5 from -4 to 1, and y (the 'rise') decreases by 8. Thus, the slope of the line through these two points is m = rise / run = -8/5
Now we have two points on the line, plus the slope. Let's write out the point-slope formula for the equation of a straight line:
y - k = m(x - h), where (h, k) is a point on the line and m is the slope of the line.
Here, using the point (1, -6), we obtain:
y + 6 = (-8/5)(x - 1) in point-slope form

Answer:
JK = 8
Step-by-step explanation:
Given 2 intersecting chords, then
The product of the measures of the parts of one chord is equal to the product of the measures of the other chord, that is
x(x + 4) = (x + 1)(x + 2) ← expand parenthesis
x² + 4x = x² + 3x + 2 ( subtract x² + 3x from both sides )
x = 2
Then
JK = x + 4 + x = 2x + 4 = 2(2) + 4 = 4 + 4 = 8

A water spout is filling a large container with water. After 5 hours the container held 24L of water. After 8 hours the container held 30L of water. At this rate, how much water was in the container at 2 hours?
Answer:
Step-by-step explanation:
This is a direct proportionality. If a water spout is filling a large container with water, hence the time taken to fill the container is directly proportional to the volume v of water. MAthematically;
t = kV
If after 5 hours the container held 24L of water, then;
5 = 24k
k = 5/24
Also if after 8 hours the container held 30L of water
8 = 30k
k = 8/30
To get the rate of the container at 2 hrs

Dominic runs a farm stand that sells peaches and grapes. Yesterday Dominic sold 34 pounds of peaches and 45 pounds of grapes for a total revenue of $192.25. Today he sold 47 pounds of peaches and 16 pounds of grapes for a total revenue of $208. Write a system of equations that could be used to determine the price of each pound of peaches and the price of each pound of grapes. Define the variables that you use to write the system.
Answer:
34x + 45y = 192.25
47x + 16y = 208
Step-by-step explanation:
Let x stand for peaches.
Let y stand for grapes.
Since we know that yesterday he sold 35 pounds of peaches ( x ) and 45 pounds of grapes ( y ) for $192.25, we can create an equation to represent this using two variables; peaches and grapes.
We can do the same thing with the amount of peaches and grapes he sold today. Once we make this equation, we will have two equations to make the system of equations to solve for x and y.

is 10x-5=8x-2x + 7 -2 equivalent?
Answer:
2.5
Step-by-step explanation:
Lets simpify one side first
8x - 2x + 7 +2
8-2 = 6
so 6x
7-2 = 5
6x+9
10x - 5 = 6x +5
(You add 5 due to it being negative on the other side)
+5 +5
10x= 6x +10
-6x -6x
4x = 10
Divide each side by 4
x = 2.5 or 10/4 or 5/2
Answer: No
Step-by-step explanation: To find whether these are equivalent, we first need to simplify the equation on the right.
8x-2x+7-2
8x-2x+5 (work- 7-2 = 5)
6x+5 (work- 8x-2x=6x) These are like terms, so we can subtract them
now that we have simplified, let's write the equations once again.
10x-5=6x+5
they are surely not equivalent

9000 dollars Is places in an account with an annual interest rate of 7.75%. How much will be in the account after 18 years, to the nearest cent?
Answer: $21555
Step-by-step explanation:
First, we need to know the interest generated on the money saved. This will be:
= Principal × Rate × Time
= $9000 × 7.75% × 18
= $12555
The amount in the account after 18 years will then be:
= Principal + Interest
= $9000 + $12555
= $21555

Answer: x=12
Step-by-step explanation:
We will use the Pythagorean Theorem since we know two sides and it is a right triangle
Pythagorean Theorem is a^2+b^2=c^2
a=5,b=x, c=13
(5)^2+(x)^2=(13)^2
25+(x)^2=169
Subtract 25 from both sides to start solving for x
(x)^2=144
Take the square root of both sides and get x=12

You plant a tree that is 36 inches tall. After one year, the tree is 43 inches tall. Which expression describes the percent of increase in the tree's height? 3643×100 43−3643 43−3636×100 43−3643×100
Answer:
19.4%
Step-by-step explanation:
Given data
Initial height=36in
Final height= 43in
% increase= Final-initial/initial*100
Substitute
% increase= 43-36/36*100
%increase= 7/36*100
%increase= 0.194*100
%increase= 19.4%
Hence the increase is 19.4%
A box has a square base with each side measuring 8 inches. The height of the box is 4 inches. What is the surface area of the box in cubic inches?
Answer:
The surface area should be 256 cubic inches
Step-by-step explanation:
The equation you use to find surface area is A=(wl+hl+hw)*2. The w stands for width (8) the l stands for length (8) and the h stands for height (4). When we put these numbers into the equation we get A=(8·8+4·8+4·8)*2. We do the multiplication first, then we add all of them up and times by 2; this gives us our answer of 256.

Based on these results, estimate the probability that 3 or more kicks are made.
Answer:
You are correct that the cross section is a rectangle, because a rectangular pyramid has 4 sides connected to the top of the rectangle.
Step-by-step explanation:
We can estimate that the probability of making 3 or more kicks in a game is approximately 0.8 or 80%.
What is simulation?Simulation is the process of creating a computer model or a physical system that behaves like a real-world system or process, in order to study its behavior or performance under various conditions.
We have,
To estimate the probability that 3 or more kicks are made, we need to count the number of trials in which 3, 4, or 5 kicks were made, and divide that by the total number of trials (which is 5 in this case).
From the table,
We can see that there are three trials in which 3 kicks were made
(trials 1, 3, and 5), one trial in which 4 kicks were made (trial 4), and no trials in which all 5 kicks were made.
The total number of trials in which 3 or more kicks were made is:
= 3 + 1 + 0
= 4
To estimate the probability, we divide the number of successful trials by the total number of trials:
P(3 or more kicks made) ≈ 4/5
Therefore,
We can estimate that the probability of making 3 or more kicks in a game is approximately 0.8 or 80%.
