For one week, Consuela kept a log of the number of pages she read each night. She read 8 pages on Monday, 11 pages on Tuesday, 10 pages on Wednesday, 7 pages on Thursday, 8 pages on Friday, 8 pages on Saturday, and 10 pages on Sunday. Create a line plot of this information. Are there any outliers in the data? Explain.
A line plot has been created based on the number of pages Consuela read each night over a week, showing the data without any outliers. Values range from 7 to 11 pages, with no significant deviations that would classify as outliers.
To create a line plot of the number of pages Consuela read each night, you would place a horizontal axis labeled with numbers representing the number of pages read, e.g., 7, 8, 10, and 11. Above each number, you would put a dot for each night that she read that number of pages. For example, she read 8 pages 3 times across the week, so above the number 8 on the line plot, you would place three dots.
Line Plot Creation and Outliers
The line plot for Consuela's reading log:
7 pages: 1 dot (Thursday)
8 pages: 3 dots (Monday, Friday, Saturday)
10 pages: 2 dots (Wednesday, Sunday)
11 pages: 1 dot (Tuesday)
To determine if there are any outliers in the data, we have to look for any dots that are not close to the other dots. An outlier is typically a data point that is significantly higher or lower than the rest of the data. In the case of Consuela’s reading log, the values are all quite close to each other, with the range being from 7 to 11 pages. There doesn't appear to be a value significantly different from the others; therefore, there are no outliers.

A consult needs to make at least $600 this week she earns $120 for each new piece and $60 for each review which of the following inequalities represents the possible combinations of reviews and new written pieces that she must complete
The possible combinations of reviews and new written pieces can be represented by the inequality 60r + 120n ≥ 600.
Explanation:To represent the possible combinations of reviews and new written pieces, we can use the variables r for reviews and n for new pieces.
The total earnings can be calculated by multiplying the number of reviews by $60 and the number of new pieces by $120, and this must be greater than or equal to $600.
Therefore, the inequality that represents the possible combinations is 60r + 120n ≥ 600.

Kristin’s three-year old sister is trying to arrange pink and red Starbursts in rows. She has 360 pink Starbursts and 150 red Starbursts. She wants to arrange them in rows so that there are either only pink or only red Starbursts in each row, and so that each row has the same number of Starburts. What is the least number of rows she can make?
The least number of rows she can make is when she puts N marbles in each row, such that N is the greatest common factor between 150 and 360.
To find the greatest common factor between 150 and 360 we can write them as the product of prime numbers.
150 = 15*10 = (3*5)*(2*5)
360 = 36*10 = (6*6)*(2*5) = (2*3*2*3)*(2*5)
greatest common factor between 150 and 360 is the product of these 3 factors:
GCF = 2*3*5 = 30
this means that we need to make rows with 30 marbles each.
150/30 = 5 rows of red marbles
360/30 = 12 rows of pink marbles.
A total of 5 + 12 = 17 rows.
A scientist conducted an experiment to determine whether an organic cleaner is as effective as a non-organic cleaner in killing germs that cause colds and the flu. To conduct the experiment, the scientist randomly selected 50 doorknobs in a hospital. He cleaned 25 of the door knobs with the organic cleaner, and he cleaned the remaining 25 door knobs with the non-organic cleaner. After cleaning and testing all of the doorknobs, the scientist reported that the organic cleaner killed 90% of germs that cause colds and the flu on the doorknobs, while the non-organic cleaner killed 95% of germs that cause colds and the flu on the doorknobs. What can be concluded from the scientist's report?
Therefore, an organic cleaner is not as effective as a non-organic cleaner in killing germs that cause colds and the flu.

Kristin spent $131 on shirts. Fancy shirts cost $28 and plain shirts cost $15. If she bought a total of 7 then how many of each kind did she buy
The required Kristin bought 2 fancy shirts and 5 plain shirts.
What are simultaneous linear equations?Simultaneous linear equations are two- or three-variable linear equations that can be solved together to arrive at a common solution.
Here,
Let's assume that Kristin bought x fancy shirts and y plain shirts. We know that the total number of shirts is 7, so:
x + y = 7
We also know that the total cost of the shirts is $131, that fancy shirts cost $28 and plain shirts cost $15. So we can write another equation:
28x + 15y = 131
Now we have two equations with two variables. We can use substitution or elimination to solve for x and y. Let's use substitution:
x + y = 7 -> x = 7 - y (subtract y from both sides)
28x + 15y = 131 -> 28(7-y) + 15y = 131 (substitute x with 7-y)
Expanding the brackets, we get:
196 - 28y + 15y = 131
-13y = -65
y = 5
So Kristin bought 5 plain shirts. We can substitute this value into either equation to find x:
x + y = 7 -> x + 5 = 7 -> x = 2
So Kristin bought 2 fancy shirts and 5 plain shirts.

a model car has been made using a scale factor if 1.5 inches:3 feet. If the actual car is 13.75 feet long, what is the length of the model?
To find the length of the model car, set up a proportion and cross multiply.
Explanation:To find the length of the model car, we need to use the scale factor given. The scale factor is 1.5 inches:3 feet. This means that for every 1.5 inches in the model, there are 3 feet in the actual car.
Given that the actual car is 13.75 feet long, we can set up a proportion:
1.5 inches / 3 feet = X inches / 13.75 feet
Cross multiplying, we get:
1.5 inches * 13.75 feet = 3 feet * X inches
Simplifying, we find that the length of the model car is approximately 6.88 inches.

Khalil is wrapping a cylindrical candle for a gift. The candle is 10 inches tall and has a diameter of 1.5 inches. How many square inches of wrapping paper will Khalil need to cover the candle? Use 3.14 for pi.
Final answer:
To cover a cylindrical candle with a height of 10 inches and diameter of 1.5 inches, Khalil would need at least 50.635 square inches of wrapping paper, calculated by adding the lateral surface area and the areas of the top and bottom circles.
Explanation:
Khalil needs to calculate the amount of wrapping paper to cover a cylindrical candle. To find the surface area needed to wrap around the sides of the candle, we'll use the formula for the lateral surface area of a cylinder, which is Area (A) = 2πrL, where 'r' is the radius and 'L' is the height of the cylinder. Given that the candle is 10 inches tall and has a diameter of 1.5 inches, we calculate as follows:
The radius (r) is half of the diameter, so r = ½ × 1.5 inches = 0.75 inches.The height (L) of the candle is 10 inches.Using π as 3.14, the area A is A = 2×π× r× L = 2× 3.14 × 0.75 inches × 10 inches = 47.1 square inches.To calculate the area needed to cover the top and bottom of the candle, we use the formula for the area of a circle, which is Area (A) = πr². The candle has two circular ends.
The area for one end A = π × 0.75² inches = 3.14 × (0.5625) inches² = 1.7675 square inches.Since there are two ends, the total area for both is 2 × 1.7675 square inches = 3.535 square inches.Adding the side area and the areas of the ends, the total wrapping paper needed is 47.1 square inches + 3.535 square inches = 50.635 square inches. Khalil should therefore use at least 50.635 square inches of wrapping paper to fully cover the cylindrical candle.

Car loan of $5,000. Student loan of $13,700. Stocks valued at $2,500. Savings of $3,000. a. Net worth is already negative. b. House value decreasing to $83,000. c. Borrowing $10,000 more in student loans. d. Selling off all owned stocks.
Answer:
The correct answer is C. Borrowing $10,000 more in students loans.
Option C - Borrowing $10,000 more in student loans is the correct Alternative.
We have list of assets and liabilities.
We have to determine which of given modification would result in negative net worth.
What is Asset and Liabilities?Assets are the items your company owns that can provide future economic benefit. Liabilities are what you owe other parties.
According to the question -
Assets = House + Car + Stocks + Savings.
Total Assets = $90,000 + $11,000 + $2,500 + $3,000 = $106500
Liabilities = Mortgage + Car loan + Student loan.
Total Liabilities = $78,000 + $5,000 + $13,700 = $96700
Now if you borrow $10000 more in student loan then -
Total Liabilities = $78,000 + $5,000 + $13,700 + $10000 = $96700 + $10000 = 1,06,700 > Assets.
Hence, Option C is the correct Alternative.

if a ship sailed due south from iceland to antarctica, it would sail through an angle of rotation of about 140 degrees around Earth's center. Find this measure in radians. Then, using 3960 miles for Earth's radius, find how far the ship would travel
the ship would travel approximately 9685.82 miles from Iceland to Antarctica.
To convert the angle from degrees to radians, we use the conversion factor[tex]\( \pi \)[/tex]radians = 180 degrees.
[tex]\[ \text{Angle in radians} = \frac{\text{Angle in degrees} \times \pi}{180} \][/tex]
In this case, the angle in degrees is 140 degrees:
[tex]\[ \text{Angle in radians} = \frac{140 \times \pi}{180} \]\[ \text{Angle in radians} = \frac{140}{180} \times \pi \]\[ \text{Angle in radians} = \frac{7}{9} \pi \][/tex]
Next, we'll find how far the ship would travel using Earth's radius. The distance traveled on a circle is given by the formula:
[tex]\[ \text{Distance} = \text{radius} \times \text{angle in radians} \][/tex]
Given Earth's radius as 3960 miles and the angle in radians as [tex]\( \frac{7}{9} \pi \)[/tex], we can calculate the distance:
[tex]\[ \text{Distance} = 3960 \times \frac{7}{9} \pi \]\[ \text{Distance} = 3080 \pi \]\[ \text{Distance} \approx 9685.82 \text{ miles} \][/tex]
So, the ship would travel approximately 9685.82 miles from Iceland to Antarctica.

In a school, the probability is 44% that a student chosen at random will be a boy. What is the probability that the student will be a girl?
The probability that a randomly chosen student is a girl is 56%, calculated by subtracting the probability of a boy (44%) from 100%.
Explanation:The question asks us to find the probability that a student selected at random is a girl, given that the probability of selecting a boy is 44%. Since the question does not provide information about any other genders, we can imply that all remaining students are girls.
Probability is a measure of the likelihood that an event will occur, expressed as a number between 0 and 1, or 0% and 100%. So, if the probability of selecting a boy is 44% or 0.44, then the probability of selecting a girl would be the remaining percentage or fraction to reach 100% or 1.
This is calculated by subtracting the probability of selecting a boy from 1 or 100%, so 1 - 0.44 = 0.56 or 100% - 44% = 56%.
Therefore, the probability that a student selected at random is a girl is 56% or 0.56.
