The five-number summary for data and construct a box plot is: 59, 62, 65, 70, 77
The IQR for the data is 8.

What is median ?

The median is a measure of central tendency in statistics. It is the value separating the higher half from the lower half of a data sample. To find the median of a data set, the data is first arranged in ascending or descending order, and then the middle value is identified. If the data set has an odd number of values, the middle value is the median. If the data set has an even number of values, the median is the average of the two middle values. The median is a useful measure of central tendency when the data contains outliers or extreme values that may affect the mean.

According to the question:
a. The five-number summary consists of the minimum, lower quartile (Q1), median (Q2), upper quartile (Q3), and maximum. To find these values:

Minimum: 59

Q1: the median of the lower half of the data, which is the median of the first 20 values (when ordered from smallest to largest): (62 + 62) / 2 = 62

Median (Q2): the middle value when the data is ordered from smallest to largest: (65 + 65) / 2 = 65

Q3: the median of the upper half of the data, which is the median of the last 20 values: (70 + 70) / 2 = 70

Maximum: 77

Therefore, the five-number summary is: 59, 62, 65, 70, 77

To construct a box plot, we can draw a number line and mark the five-number summary points. We then draw a box from Q1 to Q3, with a line at the median (Q2) inside the box. Finally, we draw whiskers from the box to the minimum and maximum values, unless there are outliers that are more than 1.5 times the interquartile range (IQR) away from the box.

b. The interquartile range (IQR) is the difference between the upper and lower quartiles, or Q3 - Q1. From part (a), we have Q1 = 62 and Q3 = 70, so:

IQR = Q3 - Q1 = 70 - 62 = 8

Therefore, the IQR for the data is 8.

Thus, the surface area of paper is needed to wrap 6 cylindrical mini muffins is 23 and 4 over 7  in².

In geometry, a cylinder is just a three-dimensional shape. A cylinder is cylindrical in shape and has a circle-shaped top and bottom. The top and bottom are both flat and uniform in size. The shape of a cylinder is best described, in my opinion, by picturing a soup can.

Given data:

surface area of 6 cylindrical mini muffins = 6*(π*r²*h)

Answer:

one solution (6, 2 )

Step-by-step explanation:

x - y = 4 → (1)

x + y = 8 → (2)

add the 2 equations term by term to eliminate y

(x + x) + (y - y) = 8 + 4

2x + 0 = 12

2x = 12 ( divide both sides by 2 )

x = 6

substitute x = 6 into (2) and solve for y

6 + y = 8 ( subtract 6 from both sides )

y = 2

the system has one solution , that is (6, 2 )

The equation of the line is y=-4x+9. In order to find the equation of the line, we must first calculate the slope (m) of the line.

Slope is a measure of the steepness of a line on a graph. It is calculated by finding the ratio of the vertical change between two points, divided by the horizontal change between the same two points.

The slope is calculated by dividing the change in y-coordinates (rise) by the change in x-coordinates (run).

In this case, the rise is -5 – (-9) = 4, and the run is 1 – 0 = 1. Therefore, the slope of the line is m = 4/1 = 4.

Next, we plug the slope and a point on the line into the point-slope form of a line equation: y - y1 = m(x - x1).

We can choose any point on the line, so let's use (0, -9).

Plugging in the values, we get:

y - (-9) = 4(x - 0)

Simplifying, we get:

y = 4x - 9

Therefore, the equation of the line is y = 4x - 9.

The lost annual income from savings on those refunds would be $43,032,000.

o calculate the lost annual income from savings on those refunds, we need to first calculate the total amount of money refunded, and then calculate the lost income from that amount.

The total amount refunded would be:

421,000 people x $3,400 per person = $1,434,400,000

Next, we can calculate the lost income from that amount at an interest rate of 3 percent. To do this, we can use the simple interest formula:

I = P x R x T

Where:

I = interest

P = principal (the amount refunded)

R = interest rate (as a decimal)

T = time (in years)

Substituting the values we have:

I = $1,434,400,000 x 0.03 x 1

I = $43,032,000

Therefore, the lost annual income from savings on those refunds would be $43,032,000.

Option b is likely to give the teachers the most accurate data for deciding the end of the year field trip for the 8th graders.

In statistics, a sample is a subset of individuals or observations taken from a larger population. The sample is used to gain insights and make inferences about the population from which it was drawn. Samples are often used when it is not feasible or practical to gather data from every individual in a population, which could be too large or too time-consuming to survey.

Here,

A random sample of 8th graders are directly affected by the decision and are therefore the most appropriate group to survey. Asking a random sample of 6th, 7th, and 8th graders (option a) would include students who are not directly affected by the decision, and may not have the same level of understanding or investment in the trip. Asking the football team (option c) would likely provide biased results, as the football team may have different preferences and priorities than the wider 8th grade class.

The number of CDs that need to be produced by the company in order to break even would be 685 CDs .

To break even, the revenue generated by selling the CDs must equal the total cost of producing them. Let's denote the number of CDs produced and sold as a.

Revenue = Price per CD × Number of CDs = 52a

Total Cost = Fixed Cost + Variable Cost × Number of CDs = 26000 + 14a

To break even, we set Revenue equal to Total Cost:

52a = 26000 + 14a

Now, we can solve for a:

52a - 14a = 26000

By answering the presented question, we may conclude that Therefore the pattern is that these three fractions are all equal and reflect the same proportion of a whole, which is half.

In mathematics, a fraction is a number that represents a component of a whole or a ratio between two things. It is shown as a top number (numerator) split by a horizontal line, also known as a vinculum, over a bottom number (denominator). For example, the fraction 3/4 indicates three-quarters of a whole split into four equal pieces. A fraction can be expressed using proper fractions, improper fractions, or mixed integers. A appropriate fraction is one with a numerator smaller than the denominator, such as 2/5.

The provided fractions 1/2, 2/4, and 4/8 have the pattern of being comparable fractions.

This indicates that even though they are worded differently, they reflect the same percentage or quantity of a total. Each fraction, in particular, represents half of the whole.

To see that these fractions are comparable, divide the numerator and denominator by the same number. For example, 2/4 may be simplified by dividing both the numerator and denominator by 2, yielding 1/2. Similarly, we may simplify 4/8 by dividing the numerator and denominator by 4, yielding 1/2.

Therefore the pattern is that these three fractions are all equal and reflect the same proportion of a whole, which is half.

The current dimensions of the rectangular soccer field are 45 yards by 100 yards.

What is area of the rectangle?

Area = Length × Width

Here let the width be "w" yards.

Then, according to the problem, the length is 55 yards longer than the width, so the length would be "w + 55" yards.

We can use this information to create an equation for the area of the rectangular field:

Area = (w + 55)w

Area = w² + 55w

Next, the problem tells us that if we increase the width by 5 yards and cut the length in half, we get a square. Let's call the side length of this square "s". We can create another equation for the area of this square:

Area = Side length²

Area = s²

We can use algebra to solve for the current dimensions of the rectangular soccer field. First, we need to find an equation for the side length of the square in terms of the current dimensions of the rectangular field:

s = w + 5 (since we increased the width by 5 yards)

s = (w + 55)/2 (since we cut the length in half)

Setting these two equations equal to each other and solving for "w" gives us:

w + 5 = (w + 55)/2

2w + 10 = w + 55

w = 45

So the width of the rectangular soccer field is 45 yards. Using the equation we created earlier for the length, we can find the length:

Length = Width + 55

Length = 45 + 55

Length = 100

Therefore, the current dimensions of the rectangular soccer field are 45 yards by 100 yards.
