amount of gas in a car's gas tank and the total distance the car has traveled since last being filled with gas
Answers
Based on my knowledge, I would expect a negative correlation between the amount of gas in a car's gas tank and the total distance the car has traveled since last being filled with gas.
As the car travels, the amount of gas in the tank decreases. Thus, if the car has traveled a long distance since being filled up, it is likely that there is less gas in the tank. Therefore, there should be a negative correlation between the amount of gas in the tank and the distance traveled, meaning that as the distance traveled increases, the amount of gas in the tank decreases.
A scatter plot of these two variables should show a downward-sloping trend, indicating the negative correlation.
Therefore the correct answer is negative correlation.

Answers
Answer:
Answer below :)
Step-by-step explanation:
Question 1:
When comparing the two sets of data in the histograms to determine the location with the most consistent temperature, we should use IQR as the measure of variability. The reason for this is that IQR is a robust measure of dispersion that is not affected by outliers and is especially useful when the data is skewed. In this case, the data in Sunny Town is skewed, and therefore the range may not be the best measure of variability. IQR is not affected by the shape of the data and provides a better measure of variability in both symmetric and skewed datasets.
Therefore, the correct answer is: IQR, because Sunny Town is skewed.
Question 2:
To determine which coffee shop typically sells the most amount of coffee per hour, we need to find the measure of center that best represents the data. Both the mean and the median can be used as measures of center, but the appropriate one depends on the distribution of the data. If the data is skewed, the median is more appropriate, and if it is symmetric, the mean is more appropriate.
Comparing the data from the two coffee shops, we find that Coffee Ground has a mean value of about 5 gallons, while Wide Awake has a median value of 4.5 gallons. The mean value for Coffee Ground is higher, but since the data is not given, it is not possible to determine the distribution of the data. Therefore, we should use the median as the measure of center for both coffee shops. In this case, we find that the median for Coffee Ground is 5 gallons, while the median for Wide Awake is 4.5 gallons.
Therefore, the correct answer is: Coffee Ground, with a median value of 5 gallons.
Question 3:
To determine which drive-thru is able to estimate their wait time more consistently, we need to compare the variability of the wait times between the two drive-thrus. We can use either the range or IQR as a measure of variability. The smaller the range or IQR, the more consistent the wait times.
Comparing the box plots for Super Fast Food and Burger Quick, we find that Super Fast Food has a smaller IQR of 4.5 (15.5 - 12), while Burger Quick has an IQR of 14.5 (24 - 9.5). Therefore, Super Fast Food has a more consistent wait time.
Therefore, the correct answer is: Super Fast Food, because it has a smaller IQR.
Question 4:
To determine which bus has the most consistent travel times, we need to compare the variability of the travel times between Bus 47 and Bus 14. We can use either the range or IQR as a measure of variability. The smaller the range or IQR, the more consistent the travel times.
Comparing the line plots for Bus 47 and Bus 14, we find that Bus 14 has a smaller IQR of 6 (18 - 12), while Bus 47 has an IQR of 8 (22 - 14). Therefore, Bus 14 has more consistent travel times.
Therefore, the correct answer is: Bus 14, with an IQR of 6.
Question 5:
To determine which girls' basketball team typically has the tallest players, we need to find the measure of center that best represents the data. Both the mean and the median can be used as measures of center, but the appropriate one depends on the distribution of the data. If the data is skewed, the median is more appropriate, and if it is symmetric, the mean is more appropriate.
Comparing the data from the two girls' basketball teams, we find that the Allstars have a median height of 68 inches, while the Champs have a median height of 67

Answers
The two inference we can make from this data is the proportion of females who prefer makeup and the significant difference in makeup preference between different groups of female.
What are the inference from the data?Based on the sample of 100 females regarding makeup preference, Sam could make the following inferences:
1. The proportion of females who prefer makeup can be estimated. Sam can calculate the proportion of females in her sample who preferred makeup and use that as an estimate of the proportion in the population. For example, if 70 out of the 100 females in the sample preferred makeup, then Sam could estimate that 70% of females in the population prefer makeup.
2. Sam could also determine if there is a significant difference in makeup preference between different groups of females. For example, she could compare the proportion of females who prefer makeup in different age groups or different ethnic groups.
To find out how many out of 375 people prefer lipstick, we need to know the proportion of people in the sample who prefer lipstick. If this information is not available, we cannot accurately determine the number of people who prefer lipstick out of 375.

a) If you were to list the sample space for this problem, there would be 36 equally likely outcomes. b) The probability of getting a sum of 9 on both dice is 136. c) The probability of getting a 5 on the first die is 16. d) The probability of getting a sum of 9 on both dice and a 5 on the first die is 1216. e) The probability of getting a sum of 9 on both dice or a 5 on the first die is 736. f) The probability of getting doubles is 16. g) The probability of getting both dice to be odd numbers is 936. h) The probability of getting doubles and both dice to be odd numbers is 136. i) The probability of getting doubles or both dice to be odd numbers is 1036.
a) The sample space of two fair dice would be 6 x 6 = 36 outcomes.
b) To get a sum of 9 on both dice, there is only one possible outcome which is rolling two 4's. Hence, the probability of getting a sum of 9 on both dice is 1/36.
c) To get 5 on the first die, there are 6 possible outcomes because the first die can show 1, 2, 3, 4, 5, or 6. Hence, the probability of getting 5 on the first die is 6/36 or 1/6.
d) The probability of getting both 9 and 5 is 1/6 x 1/36 = 1/216.
e) The probability of getting the sum of 9 on both dice or 5 on the first die is (4/36) + (1/6 - 1/36) = 11/36.
f) There are 6 possible doubles: (1,1), (2,2), (3,3), (4,4), (5,5), and (6,6). So, the probability of getting doubles is 6/36 or 1/6.
g) To get both dice to be odd numbers, we have to get either (1, 3), (1, 5), (3, 1), (3, 5), (5, 1), (5, 3). So, there are 6 possible outcomes to get both dice to be odd. Hence, the probability of getting both dice to be odd is 6/36 or 1/6.
h) The probability of getting doubles and both dice to be odd numbers is zero because we cannot roll doubles and odd numbers at the same time.
i) The probability of getting doubles or both dice to be odd numbers is the sum of their individual probabilities minus their intersection. Therefore, it is (1/6) + (1/6) - (1/6 x 1/6) = 11/36.

The trampoline park charges $50 to reseve the place and then $9 per person
Answers
The expression to represent the cost for any number of people is $50 + ($9 × x)
The trampoline park charges a fee of $50 to reserve the place. This means that, no matter how many people are going to visit the park, you will have to pay this flat fee of $50 to reserve the place. This fee is fixed and doesn't change with the number of people who will be visiting the park.
In addition to the reservation fee, the park charges $9 per person. So, if there is only one person visiting the park, you will have to pay $50 + $9 = $59. If there are two people visiting the park, you will have to pay $50 + ($9 × 2) = $68. If there are three people visiting the park, you will have to pay $50 + ($9 × 3) = $77, and so on.
To represent the total cost for any number of people, we can use the variable "x" to represent the number of people visiting the park. Then, we can express the total cost as:
Total Cost = Reservation Fee + (Cost per person × Number of people)

Answers
Answer:
same for both ; slope = -8 and y-intercept is (0, -3)
Step-by-step explanation:
First, lets write both of these in slope-intercept form!
-8x-y=3 is the same as -y = 8x+3, which is the same as y = -8x-3.
8x+y=-3 is the same as y = -8x-3.
As you can see, these equations are the same, which means that they have the same slopes and y-intercepts.
Since the equation for slope intercept form is y= mx + b where m is the slope and b is the y-intercept, this means that the slope is -8 and the y-intercept is (0, -3).

That YZ = YD = 10 cm is known.
Let DC = x and CY = 10 - x
The outer circle's radius can be expressed as 8 + 8 + x or 10 + 10 - x, which we can equate to determine its value of x
8 + 8 + x = 10 + 10 - x
Simplify
16 + x = 20 - x
Subtract 16 on both side, we get
x = 4 - x
Add x on both side, we get
2x = 4
Divide by 2 on both side, we get
x = 2
As a result, the circle's radius is

and there were 25 students in the class, how much would the
mean score increase if another student scored a 100%?
Answers
After answering the provided question, we can conclude that As a result, equation if another student achieved 100%, the mean score would rise by 0.35%.
What is equation?An equation in mathematics is a statement that states the equality of two expressions. An equation is made up of two sides that are separated by an algebraic equation (=). For example, the argument "2x + 3 = 9" asserts that the phrase "2x + 3" equals the number "9". The purpose of equation solving is to determine the value or values of the variable(s) that will allow the equation to be true. Equations can be simple or complicated, regular or nonlinear, and include one or more elements. In the equation "x2 + 2x - 3 = 0," for example, the variable x is raised to the second power. Lines are utilized in many different areas of mathematics, such as algebra, calculus, and geometry.
You can use the following formula to compute the new mean score:
(Old Sum of Scores + New Score) / (Old Number of Scores + 1) = New Mean
Where:
Old Score Sum = Mean x Number of Scores
Number of old scores = 25 (the original number of students)
The new score is 100.
Then, compute the previous score sum:
Old Score Sum = Mean x Number of Scores = 0.82 x 25 = 20.5
New Total Scores = Old Total Scores + New Score = 20.5 + 100 = 120.5
Finally, compute the new mean score as follows:
New Mean = New Score Sum / (Old Score Sum + 1) = 120.5 / 26 = 4.6346 or 46.35% (rounded to two decimal places)
As a result, if another student achieved 100%, the mean score would rise by 0.35%.

The width of a rectangle measures ( 9.5 c + 6.2 d ) (9.5c+6.2d) centimeters, and its length measures ( 5.1 c − 3.4 d ) (5.1c−3.4d) centimeters. Which expression represents the perimeter, in centimeters, of the rectangle?
Answers
The expression that represents the perimeter, in centimeters, of the rectangle is 29.2c + 5.6d.
The perimeter of a rectangle is the sum of the lengths of all its sides. In this case, the rectangle has two sides with a length (9.5c+6.2d) and two sides with a length (5.1c−3.4d).
Therefore, the perimeter can be calculated by adding the lengths of all four sides:
Perimeter = (9.5c+6.2d) + (9.5c+6.2d) + (5.1c−3.4d) + (5.1c−3.4d)
Simplifying and combining like terms, we get:
Perimeter = 2(9.5c+6.2d) + 2(5.1c−3.4d)
Perimeter = 19c + 12.4d + 10.2c − 6.8d
Perimeter = 29.2c + 5.6d
Therefore, the expression that represents the perimeter, in centimeters, of the rectangle is 29.2c + 5.6d.

A moving truck claims to hold 300 cubic feet of boxes. The truck is 25 feet in length and 8 feet in height. What is the width of the moving truck?
Answers
Answer: Width of the moving truck is 1.5 ft.
Step-by-step explanation:
Step 1: Volume of the moving truck = 300 ft³, length = 25 ft and height = 8ft. Since the truck is in the shape of a cuboid, use the formula of volume of the cuboid to find width.
⇒ Volume of truck = length × width × height
⇒ 300 = 25 × width × 8
⇒ 300 = 200 × width
⇒ width = 300/200 = 3/2 = 1.5 ft

Work out the value of u in the equation below. Give your answer to 1 d.p.
tan 34° = 9/u
Answers
Answer:
u ≈ 13.3
Step-by-step explanation:
tan34° = [tex]\frac{9}{u}[/tex] ( multiply both sides by u )
u × tan34° = 9 ( divide both sides by tan34° )
u = [tex]\frac{9}{tan34}[/tex] ≈ 13.3 ( to 1 decimal place )

a sports magazine prints 12 issues per year, and a technology magazine prints 10 issues per year. the total number of pages in all the issues of the sports magazine for one year is 32 more than the total number of pages in all the issues of the technology magazine for one year. each issue of the sports magazine has 18 fewer pages than each issue of the technology magazine. which system of equations can be used to find s, the number of pages in each issue of the sports magazine, and t, the number of pages in each issue of the technology magazine?
Answers
The number of pages in each issue of the technology magazine is 74 pages.
The number of pages in each issue of the sports magazine is s and the number of pages in each issue of the technology magazine is t.
To solve this problem, we have to write a system of equations using the given information. We have to find s and t.
System of equations can be used to find s and t; 12s = 10t + 32 and t = s + 18
The given sports magazine prints 12 issues per year and the technology magazine prints 10 issues per year.
The total number of pages in all the issues of the sports magazine for one year is 32 more than the total number of pages in all the issues of the technology magazine for one year. That means we can write an equation based on the information given for the number of pages in all the issues of the sports magazine and the technology magazine.
12s = 10t + 32
We also know that each issue of the sports magazine has 18 fewer pages than each issue of the technology magazine. That means we can write another equation based on the information given for the number of pages in each issue of the sports magazine and the technology magazine.
t = s + 18
Now, we can solve for s and t by substituting t = s + 18 in the first equation: 12s = 10(s + 18) + 32
12s = 10s + 180 + 32
12s - 10s = 180 + 32s = 56
So, the number of pages in each issue of the sports magazine is 56 pages. And, the number of pages in each issue of the technology magazine is: t = s + 18t = 56 + 18t = 74 pages.
So, each issue of the technology magazine contains 74 pages.

the local diner offers a meal combination consisting of an appetizer, a soup, a main course, and a dessert. there are three appetizers, four soups, three main courses, and three desserts. your diet restricts you to choosing between a dessert and an appetizer. (you cannot have both.) given this restriction, how many three-course meals are possible? choices
Answers
The possible combination for three-course meals to be chosen from given the restriction is equal to 16.
The restriction that can only choose either a dessert or an appetizer,
Have two choices for the first course.
For the second course,
Have 4 choices for the soup.
For the third course,
Have 3 choices for the main course,
And since can only choose one of the remaining two categories (dessert or appetizer),
Have 2 choices for the third course.
Using the multiplication principle of counting,
The total combinations of number of three-course meals possible under these conditions by multiplying the number of choices for each course,
= Number of choices for the first course × Number of choices for the second course × Number of choices for the third course
= 2 × 4 × 2
= 16
Therefore, there are 16 possible combination for three-course meals that can be chosen.
