The following examples illustrate the commutative property of multiplication.
5 · 2 · 9 = 2 · 5 · 9
3.14 · 2 = 2 · 3.14
Study the examples, then choose the statement that best describes the property.
a · b = a ÷ b
a · (b · c) = (a · b) · c
a · b = b · a
a · b = a · c
A recent study indicated that the average cost of living for a family of four in various cities across the US was $65,351 with a standard deviation of $7712. A company is thinking about relocating to a city with a lower cost of living. They would like to choose a city in the bottom 30% of those surveyed. What is the cutoff for the cost of living that would make a city eligible for relocation by this company
Answer:
The correct answer is "57408".
Step-by-step explanation:
Given:
[tex]\mu=65351[/tex]
[tex]\sigma=7712[/tex]
[tex]p=0.15[/tex]
As per the standard table, we know,
[tex]z=-1.03[/tex]
Now,
⇒ [tex]z=\frac{x-\mu}{\sigma}[/tex]
By putting the values, we get
[tex]-1.03=\frac{x-65351}{7712}[/tex]
[tex]x=57407.64[/tex]
or,
[tex]=57408[/tex]

A classic data set for investigating categorical variables deals with the RMS Titanic. The Titanic sank in the North Atlantic Ocean on April 15, 1912. There were more than 2,000 passengers and crew on board and more than 1,500 did not survive. The data set titanic.jmp located with this homework contains data on 887 passengers. For each passenger, the variables Class (class of the passenger) and Survived (whether or not the passenger lived) were recorded. A main question of interest is whether there is an association between class and survival.
1. Identify the Who for this data set.
2. Identify the What for this data set.
3. Use JMP to obtain the distribution of the variable Survived. Print out the output and turn it in with this assignment. See the Chapter 2 JMP guide for help.
4. What proportion of these passengers did not survive?
5. One variable that could be associated with the survival of a passenger is their Class. In studying this relationship, which variable is the explanatory variable? Circle the appropriate answer. Class Survived
6. Use JMP to obtain a contingency table and mosaic plot of the relationship between the Class of a passenger and whether or not they Survived. Change the contingency table so that it includes only the Count and Row % values. Print out the output and turn it in with this assignment. See the Chapter 2 JMP guide for help.
7. Explain the meaning of the number 119 from the contingency table.
8. Give the conditional distribution of Survived given that the passenger was in First class.
9. Compare this conditional distribution to the overall marginal distribution of Survived. Are the two distributions similar to each other, or are they different? Explain.
10. Based on the contingency table and mosaic plot, does it appear there is an association between Class and Survival? Circle the appropriate answer below. Then given an explanation for your answer. Yes, there is an association No, there is not an association Explain your answer:

Answer:
trapezoid
Step-by-step explanation:
One pair of sides is parallel, so the figure is a trapezoid.
__
The upper right and lower left line segments both have slopes of -2/3. Since their slopes are the same, they are parallel. The slope is found by counting grid squares between points where the lines cross grid intersections. Those crossings occur down 2 and right 3 grid squares apart, so the slope is ...
m = rise/run = -2/3

A cylindrical fuel tank is 1.25 meters high and has
a radius of 0.60 meter. If the tank can only be
filled to an 85% capacity to allow for expansion
of the fuel, what is the maximum volume of fuel?
Answer:
The maximum volume of the fuel is:
[tex]V_{fuel}=1.20 \: m^{3}[/tex]
Step-by-step explanation:
The volume of the cylinder is given by:
[tex]V=\pi r^{2}h[/tex]
[tex]V=\pi (0.6^{2})(1.25)[/tex]
[tex]V=1.41 \: m^{3}[/tex]
If the tank can be filled to 85% of its capacity, the maximum volume of the fuel will be:
[tex]V_{fuel}=1.41*(\frac{85}{100})[/tex]
[tex]V_{fuel}=1.20 \: m^{3}[/tex]

Is 12 1/2 even or odd. How do you know?
every us state has 2 senators (there are 50 states). if there are 500 members in congress, what percent of the congress is made up of senators?
Answer:
20% of the Congress is made of Senators.
Step-by-step explanation:
Our whole here is 500, since the House of Representatives and Senate combined would have 500 members in this case. So, we now need to find out how many senators there are.
[tex]2[/tex] x [tex]50[/tex] = [tex]100[/tex]
Now, since we know the fact that there are 100 senators in Congress, we will find out what percent of 500 is 100.
100 = 20% of 500. To check, we will multiply 5 by 100. We get 500.
Therefore, the answer is 20%.

Fernando invested money in a 5-yr CD (certificate of deposit) that returned the equivalent of 3.3% simple interest. He invested S1000 less in a 18-month CD
that had a 2% simple interest return. If the total amount of interest from these investments was $945.00, determine how much was invested in each CD.
Answer:
Fernando invested $ 5000 on the 5-year CD and $ 4000 on the 18-month CD.
Step-by-step explanation:
Since Fernando invested money in a 5-yr CD (certificate of deposit) that returned the equivalent of 3.3% simple interest, and the invested $ 1000 less in a 18-month CD that had a 2% simple interest return, if the total amount of interest from these investments was $ 945.00, to determine how much was invested in each CD the following calculation must be performed:
3.3 x 5 = 16.5
2 x 1.5 = 3
4000 x 0.165 + 3000 x 0.03 = 750
6000 x 0.165 + 5000 x 0.03 = 1140
5000 x 0.165 + 4000 x 0.03 = 945
Therefore, Fernando invested $ 5000 on the 5-year CD and $ 4000 on the 18-month CD.

Out of 36 people in a parade, 18 are wearing red, 15 are wearing blue, and 7 are wearing both red and blue. How many people were wearing neither color?
Answer:
3 people were wearing neither color.
Step-by-step explanation:
Red: 18/36
Blue: 15/36
Both: 7/36
Neither: ?
Both does not matter here because it does not help us find the answer to neither.
Add the red and blue together:
18/36 + 15/36
33/36
33 people are wearing red and/or blue. That leaves 3 people left over (36 - 33 = 3) who are not wearing either color.

A bag contains exactly 50 coins. The coins are either worth 10 cents, 20 cents or 50 cents and there is Atleast one of each. The total value of the coins is $10. How many different ways can this occur?
Answer:
This can happen in two ways:
1) 42 20-cent coins, 6 10-cent coins and 2 50-cent coins.
2) 30 10-cent coins, 10 20-cent coins and 10 50-cent coins.
Step-by-step explanation:
Given that a bag contains exactly 50 coins, and the coins are either worth 10 cents, 20 cents or 50 cents and there is at least one of each, and the total value of the coins is $ 10, to determine how many different ways can this occur, the following calculation must be performed:
48 x 0.5 + 1 x 0.2 + 1 x 0.1 = 24.30
48 x 0.1 + 1 x 0.2 + 1 x 0.5 = 5.5
48 x 0.2 + 1 x 0.1 + 1 x 0.5 = 10.3
45 x 0.2 + 4 x 0.1 + 1 x 0.5 = 9.9
44 x 0.2 + 5 x 0.1 + 1 x 0.5 = 9.8
42 x 0.2 + 6 x 0.1 + 2 x 0.5 = 10
30 x 0.1 + 10 x 0.2 + 10 x 0.5 = 10
Therefore, this can happen in two ways:
1) 42 20-cent coins, 6 10-cent coins and 2 50-cent coins.
2) 30 10-cent coins, 10 20-cent coins and 10 50-cent coins.
