b. How much would a 10th dog have to weight for the average weight in part (a) to be 250 pounds? Explain how you determined your answer.
Task 3
Pick a city in Maryland and determine the average high temperatures for each month. Record this in a table.
a. Create a box-and-whisker plot for the data.
b. What is the median temperature?
c. 75%ofthetemperaturesarebelowwhatvalue?Howdoyouknow? d. 75% of the temperatures are above what value? How do you know? e. What conclusions can you draw about the temperature in Maryland?
Answers
a) Data and frequency table are attached in picture #1.
b) The histogram is attached in picture #2
c) As the intervals increase the number of pieces of mail received, the frequency decreases, therefore we can say that are received few pieces of mail are received more often.
TASK 2
a) The list of breeds and weights are reported in picture #3.
In order to find the mean, sum up all the weights and divide by 9:
m = (8 + 10 + 15 + 29 + 32 + 75 + 77 + 80 + 85) / 9 = 45.67 lbs
In order to find the median, you need to select the central value of your distribution: since you have 9 values, the central one will be in the fifth position:
M = 32 lbs
In order to find the mode, you need to select the value which shows more frequently: in this case, every value shows only once, therefore the mode cannot be determined.
The data are best described by the mean because they are almost symmetrically distributed between the least and the biggest values, while the median is more towards the small-weight side of the distribution.
b) In order to have an average of 250 lbs, the tenth dog should weight 2089 lbs.
Indeed, if the average is 250 lbs for 10 dogs, it means that the total sum of their weights is 250 × 10 = 2500 lbs. We know that the sum of the first 9 dogs is 411 lbs, therefore, the tenth dog should weight 2500 - 411 = 2089 lbs.
TASK 3
The city picked is Baltimore, the year 2017.
The table is attached in picture #4.
a) The box-and-whisker plot is attached in picture #5.
b) The median is the central value of the distribution, which is:
42.4, 45.3, 46.8 | 54.7, 57.6, 66.0 | 69.1, 76.5, 80.6 | 85.8, 87.8, 90.0
where we marked with a tally the quartiles.
Since we have 12 values, the median will be the average between the two central values:
M = (66.0 + 69.1) / 2 = 67.1 °F
c) 75% of the temperatures are below 83.2 °F.
Indeed, this value represents the third quartile. The position of the third quartile can be found by the formula:
3/4 · (n + 1) = 3/4 · (12 + 1) = 3/4 · 13 = 9.75
Therefore, since we did not get in integer position, the third quartile will be the average between the numbers in position 9 and 10:
q₀.₇₅ = (80.6 + 85.8) / 2 = 83.2 °F
d) 75% of the temperatures are above 50.8 °F.
Indeed, this value represents the first quartile. Similarly to point c), the position can be found by the formula:
1/4 · (n + 1) = 1/4 · 13 = 3.25
And therefore:
q₀.₂₅ = (46.8 + 54.7) / 2 = 50.8 °F.
e) Baltimore in 2017 had a median high temperature of 67.1 °F.
25% of the year the high temperatures were warmer than 83.2 °F, with no outlier above 90.0 °F which was the hottest temperature.
25% of the high temperatures were colder than 50.8 °F, with no outlier below 42.4 °F, which was the coldest high temperature.

There’s a positive correlation between the price a passenger pays for a train ticket and the number of stops the train makes during their trip.
Which variable is most likely the lurking variable that explains the correlation?
age of passenger
outside temperature
distance being traveled
expected time of arrival
Answers
Answer:
The variable that is most likely the lurking variable that explains the correlation is:
Distance being traveled.
Step-by-step explanation:
As we know that a lurking variable is a variable that correlates between the dependent and independent variable in a scatter plot or some other statistical model.
Hence, here as the distance traveled increases the number of stops would also increase and more passengers would come and hence the cost of ticket will increase.
Hence, the lurking variable is:
Distance being traveled.
The most likely lurking variable that explains the positive correlation between the price a passenger pays for a train ticket and the number of stops the train makes during their trip is distance being traveled.
Distance being traveled: Longer trips generally cost more, and longer trips are also more likely to include more stops. Therefore, the distance being traveled is a common factor influencing both the price of the ticket and the number of stops, leading to the observed positive correlation.The other variables are less likely to explain the correlation:
Age of passenger: This does not directly affect the number of stops or the ticket price.Outside temperature: This is unrelated to the ticket price and the number of stops a train makes.Expected time of arrival: While it could be related to the overall trip duration, it doesn't directly influence the number of stops or the price independently of the distance being traveled.Hence, the distance being traveled is the lurking variable most likely explaining the correlation between ticket price and the number of stops.

What is the factorization of the polynomial below?
–x2 – 15x – 54
A. (x – 9)(x + 6)
B. (x + 9)(x + 6)
C. –1(x + 9)(x + 6)
D. (x + 9)(x – 6)
Answers
Answer:
Option C, -(x + 9)(x + 6) or,
-1(x + 9)(x + 6)
Explanation:
We can begin the factorization process by factoring out the negative -1 from each term in the polynomial. This changes the expression to:
-1(x² + 15x + 54)
This factored-out negative will follow all the way to the answer so any answer not containing a -1 factored out can eliminated. Options A, B, and D do not have this negative. Therefore, they are ruled out. But let's continue to confirm Option C.
With the polynomial within the parentheses in quadratic expression ax² + bx + c form, we start by finding which factor pair for the product and coefficient a and constant c has a sum equating to coefficient b. This may sound complicated but this is not the case in practice.
Coefficient a = 1
Constant c = 54
Coefficient b = 15
The product of a and b = 1(54) = 54
Now, we list factors of 54. I like to list them as factor pairs:
1, 54; 2, 27; 3, 18; 6, 9
Next, find which factor pair has a sum of 15. That would be 6 and 9. We now substitute these values as the coefficients b, separate the terms into pairs as binomials, and factor out their greatest common factors (GCF).
-(x² + 6x + 9x + 54)
-[(x² + 6x) + (9x + 54)]
The GCF between x² and 6x is x. The GCF between 9x and 54 is 9. So:
-[x(x + 6) + 9(x + 6)]
If the binomial within each set of parentheses matches, you have found the factors for your polynomial. They are the polynomial within the binomial within the parentheses and the GCFs that were factored out of each:
-x² - 15x - 54 = -(x² + 15x + 54) = -(x + 9)(x + 6)
Final answer:
The factorization of the polynomials [tex]-x^2 - 15x - 54[/tex] is obtained by finding two numbers that multiply to -54 and add up to -15, which are -9 and -6. The factored form is -1(x + 9)(x + 6).
Explanation:
The factorization of the polynomial [tex]-x^2 - 15x - 54[/tex] can be approached by looking for two numbers that multiply to give the product of the coefficient of x2 (which is -1) and the constant term (which is -54), and at the same time, add up to give the coefficient of x (which is -15). After finding such numbers, we can then express the polynomial in its factored form.
In this case, the numbers that satisfy these conditions are -9 and -6. Multiplying these gives 54 (which is the negative of the constant -54 when considering the leading negative sign of the polynomial), and adding them gives -15.
Therefore, the polynomial can be factored as -1(x + 9)(x + 6), which corresponds to answer option C.
Juan visited a candy store and purchased 7 pounds of candy consisting of Atomic Fireballs and Gummi Bears. Atomic Fireballs cost $4.25 per pound and Gummi Bears were on sale for $1.25 per pound. Juan spent a total of $14.75, before taxes. Let x represent the number of pounds of Atomic Fireballs and y represent the number of pounds of Gummi Bears uan purchased. Which of the following graphically represents this situation?
Answers
The Q says for fireballs to be x and gummy bears to be y. So they correspond to their axis. Knowing this you get rid of the last 2 graphs. When you plug in these vertexes into the equations, the only right answer is the graph in picture 2.
Answer:
The 2nd graph correctly represents the situation.
Step-by-step explanation:
Let the number of Atomic Fireballs= x and the number of Gummi bears= y.
Now, Juan purchased total 7 pounds of candies.
So, [tex]x+y=7[/tex]
Also, the cost of Atomic Fireballs and Gummi bears is $4.25 and $1.25 per pound respectively.
Since, Juan spent total $14.75 before taxes.
Then, [tex]4.25x+1.25y=14.75[/tex]
That is, the system of equations is given by,
[tex]x+y=7[/tex]
[tex]4.25x+1.25y=14.75[/tex]
Plotting the equations, we get that,
The 2nd graph shown below correctly represents the situation.

A. What is the probability that all 30 subjects will appropriately test as not being infected?
B. What are the mean and standard deviation of X?
C. To what extent do you think this is a viable test to use in the field of medicine?
Answers
The probability of success, i.e. the probability that a healthy subject tests positive is given as 2% = 0.02
Part A:
The probability that all 30 subjects will appropriately test as not being infected, that is the probability that none of the healthy subjects will test positive is given by:
[tex]P(X)={ ^nC_xp^x(1-p)^{n-x}} \\ \\ P(0)={ ^{30}C_0(0.02)^0(1-0.02)^{30-0}} \\ \\ =1(1)(0.98)^{30}=0.5455 [/tex]
Part B:
The mean of a binomial distribution is given by
[tex]\mu=np \\ \\ =30(0.02) \\ \\ =0.6[/tex]
The standard deviation is given by:
[tex]\sigma=\sqrt{np(1-p)} \\ \\ =\sqrt{30(0.02)(1-0.02)} \\ \\ =\sqrt{30(0.02)(0.98)}=\sqrt{0.588} \\ \\ =0.7668[/tex]
Part C:
This test will not be a trusted test in the field of medicine as it has a standard deviation higher than the mean. The testing method will not be consistent in determining the infection of hepatitis.
How much pure acid should be mixed with 6 gallons of a 50% acid solution in order to get a 70% acid solution?
Answers
Final answer:
To obtain a 70% acid solution, mix 4 gallons of pure acid with the existing 6 gallons of 50% acid solution.
Explanation:
To find out how much pure acid should be mixed with 6 gallons of a 50% acid solution to obtain a 70% acid solution, we use the concept of mixtures in percentage problems. Let x be the number of gallons of pure acid to be added.
Firstly, the amount of pure acid in the initial solution is 50% of 6 gallons, which is 3 gallons. When we add x gallons of pure acid, the total volume of the mixture becomes x + 6 gallons, and the total amount of pure acid is x + 3 gallons.
To have a 70% acid solution:
The total amount of pure acid divided by the total volume should equal 70%.
Therefore, the equation is:
(x + 3) / (x + 6) = 0.70
By solving for x:
x + 3 = 0.70(x + 6)
x + 3 = 0.70x + 4.20
x - 0.70x = 4.20 - 3
0.30x = 1.20
x = 1.20 / 0.30
x = 4 gallons
You need to mix 4 gallons of pure acid with the 6 gallons of 50% acid solution to end up with a 70% acid solution.
a physics student stands at the top of a hill that has an elevation of 56 meters. He throws a rock and it goes up in the air and then falls back past him and lands on the ground below the path of the rock can be modeled by the equation y=-0.04x^2+1.3x+56 where x is the horizontal distance in meters from the starting point on top of the hill and y is the height in meters of the rock above the ground. How far horizontally from the starting point will the rock land? Round to the nearest hundredth.
Answers
Solution:
The height y of the rock above the ground as a function of the horizontal distance x from the starting point on top of the hill can be modeled by the equation
y = -0.04x^2 + 1.3x + 56
We now set this equation equal to zero because the height of the ground where the rock will land is zero:
0 = -0.04x^2 + 1.3x + 56
Since we have a quadratic equation, we can calculate for the horizontal distance x by using the quadratic formula
x = [-b ± sqrt(b^2 - 4ac)] / 2a
x = {-1.3 ± sqrt[1.3^2 - 4(-0.04)(56)]} / 2(-0.04)
x = (-1.3 ± sqrt(10.65)) / (-0.08)
x = -24.54 meters or 57.04 meters
There are two solutions for x but one is negative, so we choose the positive value.

Which equation can be used to determine the number of hours, h, after which Fernando and Brenna will have saved the same amount of money?
Answers
Explanation:
1) Fernando's earnings:
10 + 4h ← 10 is a fix charge, h is the number of hours and 4 is the rate per hour
2) Fernando's savings
0.30 (10 + 4h) ← 30% = 30 / 100 = 0.3
3 + 1.2h ← distributive property
3) Brenna's earnings
6h ← h is the number of hours, 6 is the rate per hour
4) Brenna's savings
0.25(6h) ← 25% = 25/100 = 0.25
1.5h ←0.25 × 6 = 1.5
5) Equal savings
3 + 1.2h = 1.5h
1.5th- 1.2h = 3 ← transpose terms
0.3h = 3 ← combine like terms
h = 3 / 0.3 = 10 ← divide by 0.3
Answer: h = 10
Answer:
(C) 0.3(10 + 4h) = 0.25(6h)

sin A/ a = sin B/ b = sin C/ c
Thus,
B= 33.8 degrees
and
C= 55 degrees

Find the measure of an angle between 0 and 360 that is coterminal with 370°
Answers
A 370° angle can be thought of as one 360° and one 10° angle. The 360° would take you one full turn around a circle. The 10° angle would take you 10° into another turn. So simply going 10° would get you to the same place on the circle as going 370°. Make sense?
Final answer:
To find an angle coterminal with 370° that is between 0 and 360 degrees, subtract 360° from 370°, yielding a coterminal angle of 10°.
Explanation:
To find the measure of an angle between 0 and 360 degrees that is coterminal with 370°, we simply subtract 360° from the given angle until the result falls within the desired range. Here is the calculation:
Start with the given angle: 370°.
Subtract 360° from 370° to find the coterminal angle: 370° - 360° = 10°.
The resulting angle of 10° is between 0° and 360° and is therefore the coterminal angle we are seaching for.
