Create a dot plot to represent the data. what can you conclude about the dot plot of the data set? select the three best answers. the range of the number line should be 0 to 7 to represent the frequency. four families said they ate out twice the previous week. one family said they ate out 5 times the previous week. the data set is symmetrical. the median best represents the data set.
The range of the dot plot can be from zero to seven because it covers the given data set. Then the correct options are A, B, and C.
What is frequency?The element which appears a number of times are called frequency.
The data set shown below represents the number of times some families went out for dinner the previous week.
The data set is given as:
4, 2, 2, 0, 1, 6, 3, 2, 5, 1, 2, 4, 0, 1
Rearrange in ascending order
0, 0, 1, 1, 2, 2, 2, 2, 4, 4, 5, 6
Data Frequency
0 2
1 2
2 4
3 0
4 2
5 1
6 1
Because the median is 2, and the data points to the left and right are not symmetrical, the data set is not symmetrical.
From the given data set
4 has a frequency of 2
5 has a frequency of 1
Then the range of the dot plot can be from zero to seven because it covers the given data set.

The quadratic regression equation of company X sales would have a degree of 2
The quadratic regression equation is y = -507.61x^2 +23372.94x -170697.85The profit for selling at $22.75 is $98316.63The quadratic regression equationTo determine the quadratic regression equation, we make use of a graphing calculator
From the graphing calculator,we have the following calculation summary
a = -507.61b = 23372.94c = -170697.85A quadratic regression equation is represented as:
y = ax^2 + bx + c
So, we have:
y = -507.61x^2 +23372.94x -170697.85
Hence, the quadratic regression equation is y = -507.61x^2 +23372.94x -170697.85
The profit for selling at $22.75This means that:
x = 22.75
So, we have:
y = -507.61 * 22.75^2 + 23372.94 * 22.75 -170697.85
Evaluate
y = 98316.63

A bicycle manufacturer is studying the reliability of one of its models. the study finds that the probability of a brake defect is 4 percent and the probability of both a brake defect and a chain defect is 1 percent. if the probability of a defect with the brakes or the chain is 6 percent, what is the probability of a chain defect? 1.5 percent 2 percent 2.5 percent 3 percent
Using Venn probabilities, it is found that there is a 0.03 = 3% probability of a chain defect.
What is a Venn probability?In a Venn probability, two non-independent events are related to each other, as are their probabilities.
The "or probability" is given by:
[tex]\rm P(A \cup B ) = P(A)+P(B)-P(A\cap B)[/tex]
In this problem, the events are:
Event A: Brake defect.
Event B: Chain defect.
For the probabilities, we have that:
The study finds that the probability of a brake defect is 4 percent, P(A) = 0.04.The probability of both a brake defect and a chain defect is 1 percent, P(A∩B) = 0.01.The probability of a defect with the brakes or the chain is 6 percent, P(A∪B) = 0.06.Substitute all the values in the formula
[tex]\rm P(A \cup B ) = P(A)+P(B)-P(A\cap B)\\\\0.06=0.04+P(B)-0.01\\\\P(B)=0.06-0.04+0.01\\\\ P(B)=0.03[/tex]
0.03 = 3% probability of a chain defect.
Hence, there is a 0.03 = 3% probability of a chain defect.

help quick please
Answer:
960 cm^3
Step-by-step explanation:
The volume of any object is found by multiplying the area of the base times the height. I'll use the triangular sides as the base in this case. The area of the triangle is (bh)/2, so this calculation is:
(16x12)/2 = 96
The height is 10, so Volume is 96 x 10 = 960 cm^3

How to solve and what is the final answer to the question
Answer:
12
Step-by-step explanation:
Differentiate the equation. It will give you -1/6x + 2 = dy/dx.
Let dy/dx = 0 (you do this because the highest point is usually the turning point. The gradient is zero at the turning point, meaning that you'd have to set dy/dx to be zero to figure out the highest point).
Then rearrage for x
-1/6x+2=0
1/6x = 2
x = 12
I want help to solve question
Answer:
Step-by-step explanation:
When we add the area of semicircle I and III of same radius, we get a cirlce.
diameter = 48 cm
r = 48/2 = 24 cm
Area of I and III = area of circle
= πr²
= 3.14 * 24 *24
= 1808.6 cm²
Figure II:
length = diameter of the bigger semicircle = 48 cm
width = diameter of the smaller circle = 14 cm
Area of rectangle (figure II) = length *width
= 48 * 14
= 672 cm²
Smaller semicircle A & B
diameter = 14 cm
r = 14/2 = 7 cm
Area of Semicircle A & B = Area of a circle
[tex]\sf = \dfrac{22}{7}*7*7\\\\ = 22*7\\\\= 154 \ cm^{2}[/tex]
Area of shaded region = area of rectangle II + area of figure I & III - area of A &B
= 672 + 1808.6 - 154
= 2326.6cm²

A box contains 6 red marbles, 4 blue marbles, and 8 yellow marbles.
13. Find P(yellow then red) if a marble is selected, and then a second marble
is selected without replacing the first marble.
Answer:
Step-by-step explanation:
The total number of marbles is 6 + 8 + 4 = 18]
If the first marble drawn is yellow, that happens with a probability of 8/18
So the important thing to note is that now there are 17 marbles,
Now a red marble is drawn. We didn't replace the yellow.
There are 6 red marbles.
So the chances of getting a red marble is 6/17
Answer. P(Y then R) = 8/18 * 6/17 = 48/306
48 / 306 reduces down to 8/51 = 0.156

PLEASE HELP ME OUT 39 POINTS
Answer:
Option A for part (a) and Option B for part (b)
Step-by-step explanation:
Step 1: Determine the ratios in part a
First Batch --> 8 minutes / 2 customers = 4 minutes per customer
Second Batch --> 18 minutes / 6 customers = 3 minutes per customer
Third Batch --> 21 minutes / 7 customers = 3 minutes per customer
In part (a) we would choose option a which is that it does not always take the same amount of time to serve each customer.
Step 2: Determine the ratios in part b
First Batch --> 27 points / 3 dollars = 9 points per dollar
Second Batch --> 45 points / 5 dollars = 9 points per dollar
Third Batch --> 63 points / 7 dollars = 9 points per dollar
In part(b) would choose option b which is that each dollar spent appears to earn the same number of points which would give us 8 dollars for 72 points.
Answer: Option A for part (a) and Option B for part (b)

0

16
Answer:
The graph y = 18x2 + mx + 2= 12
So the answer is 12
The value of m does the graph of y = 18 x² + m x + 2 have exactly one x-intercept is 12.
What is Intercept?The points where a line crosses an axis are known as the x-intercept and the y-intercept, respectively.
We have Equation.
y = 18 x² + m x + 2
Now, to find exactly one intercept we will use Discriminant Method as
D = m² - 4 x 18 x 2 = 0
m² - 144 = 0
m² = 144
m = -12 or m = 12
Thus, the required value of m is 12.
