for both categorical and numerical variables the difference between the relative frequency and the percent frequency is option B: The percent frequency equals the relative frequency multiplied by 100.
What is the frequency about?Relative frequency and percent frequency are two measures of the frequency of an event or category within a data set.
Relative frequency is the ratio of the number of times an event or category occurs divided by the total number of events or categories.
Percent frequency is the relative frequency expressed as a percentage. This means that it is equal to the relative frequency multiplied by 100. In other words, the percent frequency represents the proportion of occurrences of an event or category as a percentage of the total number of events or categories.
So, the difference between relative frequency and percent frequency is that relative frequency is a ratio, while percent frequency is the same ratio expressed as a percentage.

question 1what is the number of 6-card hands with three hearts and three spades?
The probability of a 6-card hand with three hearts and three spades is 0.001862, or 1/535
Probability is the mathematics of chance; it is the study of calculating the likelihood of certain outcomes in any given situation.
Here we have to find the probability of a particular 6-card hand consisting of three hearts and three spades is determined first by the fact that there are 13 hearts and 13 spades in a standard deck of 52 cards.
To calculate the probability of a 6-card hand consisting of three hearts and three spades, one must first consider that the order of the cards in a hand does not matter.
The total number of combinations of three hearts and three spades that can be drawn from a standard deck of cards is
=> 4,824.
This number can be calculated by an equation that uses the number of hearts, spades, and cards in a standard deck
=> (13 x 13 x 52).
Then the probability of a 6-card hand consisting of three hearts and three spades is calculated by dividing the number of combinations of three hearts and three spades
=> (4,824) / (2,598,960).
This equation yields a probability of 0.001862, or a 1 in 535 chance of getting a 6-card hand with three hearts and three spades.

at the city museum, child admission is $5.80 and adult admission is $9.70. on wednesday, 156 tickets were sold for a total sales of $1290.90. how many child tickets were sold that day?
Let x be the number of child tickets sold on Wednesday. Then, the number of adult tickets sold can be represented as 156 - x.
The total amount of money generated from the sale of child tickets is 5.80x, and the total amount of money generated from the sale of adult tickets is 9.70(156 - x). The total sales for the day were $1290.90, so we can set up the following equation:
5.80x + 9.70(156 - x) = 1290.90
Expanding the right-hand side and solving for x, we can isolate x:
5.80x + 1481.20 - 9.70x = 1290.90
-4.90x + 1481.20 = 1290.90
-4.90x = -190.30
x = 39
So, 39 child tickets were sold on Wednesday. This is because the total number of tickets sold is 156, and since we know the number of child tickets sold, we can calculate the number of adult tickets sold by subtracting the number of child tickets from the total.

What is a pie chart?
The “pie chart” is also known as a “circle chart”, dividing the circular statistical graphic into sectors or sections to illustrate the numerical problems. Each sector denotes a proportionate part of the whole. A pie chart requires a list of categorical variables and numerical variables. To find out the composition of something, Pie-chart works the best at that time. In most cases, pie charts replace other graphs like the bar graph, line plots, histograms, etc.
The total value of the pie is always 100%.

What is the Constant of Proportionality?
Why is the graph proportional? How do you know? What do you see? Explain.
The constant of proportionality is 6.
How to find the Constant of Proportionality?
The constant of proportionality is the ratio that relates two given values in what is known as a proportional relationship. It is also known as unit rate and it is usually expressed by k.
Mathematically, k = y/x.
To find the Constant of Proportionality, pick any point from the graph. That is:
Point (20, 120). Thus, x = 20, y = 120
Constant of Proportionality (k) = y/x
k = 120/20 = 6
The graph is proportional because the Constant of Proportionality of nay point on the graph is the same.
What I see is that the graph starts from the origin. That is the initial value of x and y are zero.

The inequality for the range of the possible length for the third side is 100<x<500.
Inequalities can be defined as expressions that involve the use of symbols such as >, <, ≥, and ≤. In order to solve an inequality, we need to find what is called its range, or ranges, which are values that can satisfy the given inequality.
We already know that no side of a triangle can exceed the sum of the other two sides. The third side needs to be less than 500 (300 + 200) and greater than 100 ( 300 - 200)

The maximum mortgage payment allowed for someone with an annual salary of $56,750 is $1891666.
What is the mortgage payment?A mortgage payment usually consists of four parts: principal, interest, taxes, and insurance. The Principal portion is the amount that is deducted from your outstanding loan balance. The cost of borrowing money is expressed as interest. Your interest rate and loan balance determine the amount of interest you pay.According to the 28/36 guidelines, 28% of your gross monthly income should be spent on housing finances, and 36% of your total monthly income can be considered debt-free income.
Allow Total gross monthly income to equal $ x
The debt amount is $ 56,750.
So, 36% of x = $ 56,750
36x/100 = 56,750
x = 56,750 x 100 / 36
x = 157638.8

by using taylor seriwsone can be sure that for all values of x that satisfy |x|<1/2, |cosx-(1-x^2/2)| is less than or equal to what numerical value
For all values of x that satisfy |x| < 1/2, |cos(x) - (1 - x^2/2)| is less than or equal to a very small positive number.
The Taylor series for cos(x) is:
cos(x) = 1 - x²/2 + x⁴/4! - x^6/6! + ...
So, if |x| < 1/2, then:
|cos(x) - (1 - x²/2)| = |x²/2 - x⁴/4! + x⁶/6! + ...|
This expression on the right-hand side is a sum of absolute values of the terms in the Taylor series expansion of cos(x), which are all positive for |x| < 1/2. Therefore, the absolute value of the expression on the right-hand side is less than or equal to the sum of all of these positive terms, which approaches 0 as x approaches 0.
Therefore, for all values of x that satisfy |x| < 1/2, |cos(x) - (1 - x²/2)| is less than or equal to a very small positive number.

(a) (10 points) suppose we know that at least one person is taller than x. what is the probability that the other person is shorter than x? (b) (10 points) suppose we know that the person chosen second is taller than x. what is the probability that the first person chosen is shorter than x?
(a) The probability that the other person is shorter than x is = 1/2
(b) The probability that the first person chosen is shorter than x is 1/2.
(a) If we know that at least one person is taller than x, then there are two cases to consider:
The first person chosen is taller than x:
In this case, the probability of the second person being shorter than x is 1/2.
The second person chosen is taller than x:
In this case, the probability of the first person being taller than x is 1/2.
The total probability that at least one person is taller than x and the other person is shorter than x is the sum of these two cases:
P = (1/2) * (1/2) + (1/2) * (1/2)

a sinusoidal graph has a maximum at the point (4,12) and a minimum at the point (11,5). determine the midline of the graph.
The midline of the graph is a horizontal line with y = 8.5.
The midline of a sinusoidal graph is the average of its maximum and minimum values, which represents the average height of the graph over one period. To find the midline, we need to find the average of the y-values of the maximum and minimum points.
The maximum point is (4,12) and the minimum point is (11,5), so the average of the y-values is (12+5)/2 = 8.5. This represents the y-intercept of the midline, which is a horizontal line. Therefore, the midline of the graph is a horizontal line with y = 8.5.
The midline of a sinusoidal graph separates the graph into two parts: the portion above the midline, where the graph is increasing, and the portion below the midline, where the graph is decreasing. The midline also provides important information about the amplitude and frequency of the graph.
