Describe a real-life situation where the median and the interquartile range are likely the best measures of center
and variation to describe the data. Explain your reasoning.
Answers
One real-life situation where the median and the interquartile range are likely the best measures of center and variation to describe the data is in income distribution analysis.
Income distribution is often highly skewed, with a few high-income earners at one end and a larger number of lower-income earners at the other end. In such cases, the mean can be heavily influenced by extreme values, such as a small number of very high incomes, leading to a distorted representation of the typical income level.
The median, on the other hand, is not affected by extreme values and represents the middle value of the income distribution. It provides a more accurate measure of the central tendency of the data, representing the income level that separates the higher half from the lower half of the population.
The interquartile range (IQR) is a measure of dispersion that captures the spread of the middle 50% of the data. It is calculated as the difference between the third quartile (Q3) and the first quartile (Q1).
The IQR is less sensitive to extreme values and outliers than the range or standard deviation, making it a robust measure of variability. In income distribution analysis, the IQR can provide insights into the income gap between the middle-income earners, which may be more representative of the majority of the population.
By using the median and the interquartile range in income distribution analysis, we can obtain a more accurate understanding of the central tendency and variation in income levels, without being overly influenced by extreme values that can skew the mean and other measures of dispersion.

If a card is picked at random from a standard 52-card deck, what is the probability of getting a heart or a 8 of clubs? Give your answer as a fraction.
Answers
Given:
Number of hearts in deck of cards = 13
Number of 8 of clubs in a deck of cards = 1

An open box is constructed from a sheet of A4-size paper by cutting equal-size squares from the four corners and then folding the resulting tabs upwards. If A4-size is 210 mm by 300 mm, what is the maximum possible volume that the box can have?
Answers
The maximum possible volume that the box is 446,514.56 cubic millimeters.
Let's assume that we cut squares with side length "x" from each corner of the A4-size paper.
When we fold the resulting tabs upwards, the dimensions of the base of the box will be reduced by 2x on each side.
Therefore, the length of the base of the box will be (300 - 2x) mm, and the width will be (210 - 2x) mm.
The height of the box will be equal to the side length of the squares we cut, which is "x" mm.
The volume of the box is given by the product of its length, width, and height:
Volume = (300 - 2x) (210 - 2x) x
To find the maximum possible volume, we can take the derivative of the volume function with respect to "x" and set it equal to zero:
dV/dx = 0
dV/dx = (300 - 2x)(210 - 2x) + x(-2)(210 - 2x) = 0
(300 - 2x)(210 - 2x) - 2x(210 - 2x) = 0
(300 - 2x)(210 - 2x) - 420x + 4x² = 0
63000 - 840x + 4x² - 420x + 4x² - 420x + 4x³ = 0
8x³ - 1680x + 63000 = 0
x³ - 210x + 7875 = 0
On solving we get x= 46.4 mm
Now, Volume = (300 - 246.4)(210 - 246.4 46.4
= 446,514.56 cubic millimeters.

Answers
Answer:
42.4
Step-by-step explanation:
A = πr^2 = π·6^2 ≈ 113.09734
113.1 is the overall area of the pizza, now you must divide the area by 8 because there are 8 slices.
113.1/8 = 14.14
14.14 is the area of each slice so multiply that by 3 because thats the amount of slices juan ate.
14.14·3 = 42.4

Mayzie's Masks has a monthly demand of 250 masks. It costs $100 to place an order
and the holding cost is 20% of the cost of a mask, which is $30. What is the total
cost?
Answers
Answer:
$951
Step-by-step explanation:
EOQ = Sqroot{(2*Annual Demand*Ordering cost)/Holding cost}
= Sqroot{(2*250*12*100)/(0.2*30)}
= 317 Units Approximately
Total Holding cost = Average Inventory * Holding cost per unit
= (EOQ/2)*Holding cost per unit
= (317/2)*(0.2*30)
= $951
So by knowing the holding cost and the percentage that it represents, we want to find the total cost of the masks. We will find that the cost is $150.
We know that the holding cost is 20% of the cost of a single mask, so if the cost of a mask is C, the holding cost is:
(20%/100%)*C = 0.2*C
And we know that this is equal to $30, so we get:
0.2*C = $30
Now we can solve this for C, the total cost of a mask:
C = $30/0.2 = $150.

The function h(t) = -16t2 + 48t + 28 models the height (in feet) of a ball where t is the time (in seconds).
What is the maximum height that the ball reaches? Just write the numerical answer - do not include h = or any units in your
answer.
Answers
Answer:
64
Step-by-step explanation:
[using calculus] When the function h(t) reaches its maximum value, its first derivative will be equal to zero (the first derivative represents velocity of the ball, which is instantaneously zero). We have \(h'(t) = -32t + 48\), which equals zero when \(t = 3/2 = 1.5\). The ball therefore reaches its maximum height when t = 1.5. To find the maximum height, we need to find h(1.5), which is 64 feet.
[without calculus] This is a quadratic function, so its maximum value will occur at its vertex. The formula for the x-coordinate of the vertex is -b/2a, so the maximum value occurs when t = -48/(2*16), which is 1.5. The maximum height is h(1.5), which is 64 feet.

Solve for the unknown. q- 5/6=1 5/6
Answers
Answer:
q=8/3
Step-by-step explanation:
First, add 5/6 to both sides to get rid of -5/6 to get q=16/6 then simplify to q=8/3.
Answer:
\(q=2\frac{2}{3}\)
Step-by-step explanation:
The given equation consists of a fraction and a mixed number.
First, convert the mixed number into an improper fraction by multiplying the whole number by the denominator of the fraction, adding this to the numerator of the fraction, and placing the answer over the denominator:
\(q-\dfrac{5}{6}=1 \frac{5}{6}\)
\(q-\dfrac{5}{6}=\dfrac{1 \cdot 6+5}{6}\)
\(q-\dfrac{5}{6}=\dfrac{11}{6}\)
Now, add 5/6 to both sides of the equation to isolate q:
\(q-\dfrac{5}{6}+\dfrac{5}{6}=\dfrac{11}{6}+\dfrac{5}{6}\)
\(q=\dfrac{11}{6}+\dfrac{5}{6}\)
As the fractions have the same denominator, we can carry out the addition by simply adding the numerators:
\(q=\dfrac{11+5}{6}\)
\(q=\dfrac{16}{6}\)
Reduce the improper fraction to its simplest form by dividing the numerator and denominator by the greatest common factor (GCF).
The GCF of 16 and 6 is 2, therefore:
\(q=\dfrac{16\div 2}{6 \div 2}\)
\(q=\dfrac{8}{3}\)
Finally, convert the improper fraction into a mixed number by dividing the numerator by the denominator:
\(q=2 \; \textsf{remainder}\;2\)
The mixed number answer is the whole number and the remainder divided by the denominator:
\(q=2\frac{2}{3}\)

Answers
By looking at the graph of the linear equation, we conclude that the y-value for x = -3, is y = -9
what would the y-value be for an x-value of -3?Here we have the graph of a linear equation. What the graph tells us is "what is the value of y for each value of x".
So, if we want to find the value of y when we have x = -3, then:
We need to find the value x = -3 on the horizontal axis.Then we move vertically upwards (or downwards, depending on the case) until we reach the graphed equation.Once we reached the graphed equation, we move horizontally until we meet the vertical axis.The value at which we meet the horizontal axis gives the value in the range related to the value in the domain from which we started.Following these steps, you should be able to see that, when x = -3, the value of y is -9
So we conclude that the y-value for x = -3, is y = -9
