Answer:
There is one knave
Step-by-step explanation:
Let's analyze the two possible scenarios, from the unheard Fred's answer
<u><em>- SCENARIO 1: Fred is a knave.</em></u>
If Fred is a Knave, he must have told to the other natives that he wasn't, <u>remember that Knaves will never tell the truth.</u> In that sense, George said that Fred denied being a knave, he would be telling the truth (Fred is a knight) and Quincy said that Fred is a knave, which would also be true (Quincy is a knight too).
<em><u>-SCENARIO 2: Fred is a knight</u></em>
If Fred is a knight, he must have told to the other natives that he wasn't a knave, he would be telling the truth. In this case, George would also be telling the truth by ensuring that Fred denied being a knave (Fred is a knight). However, Quincy would be lying to ensure that Fred is a knave. In this scenario Quincy is the knave
In conclusion, in both scenarios, there is only one knave.
Answer:
i. A bar graph is an appropriate display.
ii. A bar graph is appropriate because the frequencies are given.
Step-by-step explanation:
A bar graph is a graphical method that can be used to present an information from a sample of data. It requires drawing of bars of equal width and distance with respect to the information given.
While a pie chart is a method that requires presenting information in a circular chart with respect to each data in sectors of different central angles.
For the given question, the most appropriate method to use is the bar graph with respect to the given information. Thus, the statements that are correct about the data in the table are:
i. A bar graph is an appropriate display.
ii. A bar graph is appropriate because the frequencies are given.
Answer:
1x² + 1x -3
Step-by-step explanation:
A quadratic regression is the process of finding the equation of the parabola that best fits a set of data. As a result, we get an equation of the form: 
To compute manually the values of a, b and c is a rather complicated process using a technique known as least squares method.
However, we can use a scientific calculator to compute the three values and arrive at the quadratic equation
Using the points provided, the values are:
a = 1, b = 1, c = -3
The function is 1x² + 1x -3
Note that this is a best-fit function it does not necessarily pass through all 3 points but approximates. The attached graph shows that the function does indeed pass through 2 of the 3 points
Answer:
Using EMV analysis, the number of units of the new product should be purchased for resale = Purchase 7.
The maximum EMV of profit you can make is 270.
Explanation:
We can use the following method to solve the given problem
Solution:
Using EMV analysis,
EMV (Purchase 6 for resale)= 6(40)(0.1) + 6(40)(0.4) + 6(40)(0.5)=240
EMV (Purchase 7 for resale) = [6(40)-60](0.1) +7(40)(0.4) + 7 (40)(0.5) = 270
EMV (Purchase 8 for resale) = [6(40)-2(60)] (0.1) + [7 (40) - 60] (0.4) + 8(40)(0.5)= 260
Largest EMV= 270; Choose to purchase 7 units for resale.

Answer:
3x = 95
95 ÷ 3 = 31.6666......
I used bus stop method to work this out
Therefore the estimate would be:
x = 32 or 31.7 depending on how accurate it needs to be.
You could alternatively change 95 to 96 and calculate it easily like that
