Likes hamburgers Does not like hamburgers Total
Likes burritos 39 77
Does not like burritos 95 33
Total 134 205
Part A: What percentage of the survey respondents liked hamburgers but do not like burritos? Show all work. (3 points)
Part B: What is the marginal relative frequency of all customers who like hamburgers? Show all work. (3 points)
Part C: Which category has the lowest joint relative frequency? Show all work. (4 points)
Answers
a) The percentage of the survey respondents liked hamburgers but do not like burritos is of: 46.34%.
b) The marginal relative frequency of all customers who like hamburgers is of: 0.6537.
c) The lowest joint frequency is not liking neither of hamburgers or burritos.
How to obtain frequencies and percentages?The relative frequency is obtained as the division of the number of desired outcomes by the number of total outcomes.
The percentage is calculated as the multiplication of the relative frequency by 100%.
From the table given by the image at the end of the answer, the total number of people in the survey is of:
77 + 128 = 134 + 71 = 205.
The percentage for item a is then calculated as follows:
95/205 x 100% = 46.34%.
The relative frequency for item b is then calculated as follows:
134/205 = 0.6537.
The joint frequencies are found completing the table, considering the sums for the rows and columns, as follows:
Like both: 134 - 95 = 39.Like burritos but not hamburgers: 38.Like hamburger and do not like burritos: 95.Do not like both: 71 - 38 = 33. -> lowest.Missing InformationThe table is given by the image shown at the end of the answer.

What is balance sheet?A balance sheet is a financial statement that lists the assets and liabilities of a corporation at a certain point in time. It is one of the three primary financial statements—the other two being the income statement and cash flow statement—that are used to assess a company's performance.
The weekly income is of $21,000, while a month is composed by four weeks, hence the monthly income is of:
=4 x $21,000
= $84,000.
Then the percentages of each expenses are applied to find the values, for example, 42% of that is for employee wages, hence:
= 0.42 x 84,000
= $ 35, 280
From the details we get Employee Wages 42% of $35,280.00
Hence, the balance will be of zero and option A is correct.

What is a cyclic quadrilateral?An inscribed four-sided polygon in a circle is known as a cyclic quadrilateral. With the specified side lengths, it has the largest area feasible.
Given the quadrilateral inside a circle.
The angle v is given by:
45° +v + 55°=180°
v + 100° = 180°
v = 180° - 100°
v = 80°
Since the quadrilateral is cyclic, the sum of its opposite angle is 180°.
Therefore,
y + v = 180°
y + 80° = 180°
y = 100°
Using the property of cyclic quadrilateral, it follows:
w = 45° and x = 55°
Hence, the measures of the angles are v = 80°, y = 100°, w = 45°, and x = 55°.

why does the normal distribution have an importance in statistics of wether or not iut appears in nature
Answers
The normal distribution have an importance in statistics of whether or not out appears in nature, because it fits several natural phenomena.
For exa. measurement error, heights, IQ scores, and physical activity measures all follow the normal distribution.
In this question we need to describe why does the normal distribution have an importance in statistics of whether or not out appears in nature.
We know that if we plot the probability distribution and it forms a bell-shaped curve. If the mean, mode, and median of the sample are equal then the variable has normal distribution.
A normal distribution is dependent on two parameters of the data set: mean and the standard deviation of the sample.
This characteristic of the normal distribution makes it extremely simple.
Also, the normal distribution is important because of the Central limit theorem.
It makes math easy - like calculating moments, correlations between variables, and other calculations that are domain specific.
So, the normal distribution have an importance in statistics of whether or not out appears in nature.

Answers
Answer: The ratio of red marbles to blue marbles is 3:6. This can be written as a fraction as 3/6, which simplifies to 1/2.
Step-by-step explanation:
To find the ratio of two quantities, you can divide the number of one type of item by the number of another type of item. In this case, the ratio of red marbles to blue marbles is 3 marbles / 6 marbles, which simplifies to 1/2.
It's important to note that a ratio is not the same thing as a percentage or a fraction. A ratio is a comparison of two quantities, while a percentage is a measure of a quantity relative to the total amount and a fraction is a division of one number by another.

Answers
The answer to this Question based on Compound Interest is 1690.2$
What is Compound Interest?
Compound interest is a type of interest that is calculated not only on the initial principal but also on the accumulated interest of previous periods. It is the result of reinvesting interest, rather than paying it out, so that interest in the next period is then earned on the principal plus previously accumulated interest. It is the concept of earning interest on interest, which causes the total balance to grow at a faster rate than simple interest. Compound interest is often referred to as the eighth wonder of the world, as it is a powerful financial concept that can yield impressive results over a long period.
Initial money deposited = 900$
1$ turns into 1.878$ after 12 years of Compound Interest
hence by basic manipulation we can do like

Find the total surface area of this triangular prism 13cm 5cm 12cm 9cm 15cm 20cm.
Answers
The surface area of the triangular prism is 924 cm².
What is the triangular prism?
When a prism has three rectangular sides and two triangular bases, the prism is said to be triangular. A pentahedron, that is.
Volume is calculated using the formula volume = 0.5 * b * h * length, where b is the triangle's base length, h is its height, and length is the prism length.
Area is defined as length * (a + b + c) + (2 * base area), where a, b, and c are the triangle's sides and base area is the triangle's base area.
The surface area is equal to the area of the two triangles + area of the three rectangles.
Area of two triangles:
12 × (9+5) × 1/2
= 84
84(2) = 168
Area of the three rectangles:
15 × 20 + 13 × 20 + 14 × 20
= 840

What is slope?A line's steepness and direction are measured by the line's slope.
Without actually using a compass, determining the slope of lines in a coordinate plane can assist in forecasting whether the lines are parallel, perpendicular, or none at all.
Any two different points on a line can be used to calculate the slope of any line.
A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively.
Two locations located on a straight line can be used to determine a line's slope. We can use the slope of line formula if we know the two spots' coordinates. These two points' coordinates should be-

How to illustrate the irrational number?The square root of an integer for x and a positive integer greater than zero for y are described in the statement as values of x and y that could be irrational numbers.
We have provided x and y values that could be irrational numbers. Any real number that cannot be expressed as the quotient of two integers is considered an irrational number. Positive whole numbers are not considered negative integers, nor are negative integers, or numbers below zero.
Consequently, we can say that A, C, or D do not demonstrate the irrational numbers since they are all expressed as integers.

1. The negative flips the parabola upside down so there is a maximum
2. The 1/2 means there is a vertical shrink
3. -3 means the graph moves to the RIGHT 3 units (X sign always changes)
4. +12 means the graph shifts up 12 units
Step-by-step explanation:
g(x)=x^2 is the parent function. This is the most basic parabola, and transformations are added to alter the function’s lateral and vertical location and width or length.
Now that we have the parent function, let’s address the transformations done to it. Remember, when identifying transformations, remover to follow PEMDAS; act like you are inputting a value in for x and following PEMDAS to observe how the function is altered.
• Lateral shift 3 units to the right
*Remember, horizontal translations have opposite signs, so even though x is subtracted by 3, it will actually move to the right towards the positive direction.
•Reflect over the x-axis
•Shrink by a factor of 1/2
*This will produce a wide parabola
• Vertical shift up 12 units

Step-by-step explanation:
Would buy again customers are people satisfied.
Therefore we have
satisfied overall people surveyed
In numbers, this looks like
1300/2000
Simplifying we get
13/20
If you use a calculator then you can input this equation. However, if you want to be big-brained you can use simple math to get the decimal answer fast.
13/20 = (13•5)/(20•5) = 65/100 = 0.65
But if you need a percent value then you are not done!
0.65 is not a percent. To get a percent you multiply your fraction or decimal by 100. Therefore we get 0.65•100 = 65%
65% of people would buy the car again. Therefore 65% of people are satisfied with that car.

D 3 is the ratio of his car’s fuel tank capacity and his fuel economy.
Answers
B) 3 is the ratio of his speed and his car's fuel economy.
What is speed?Velocity is the pace and direction of an object's movement, whereas speed is the time rate at which an object is traveling along a path. In other words, velocity is a vector, whereas speed is a scalar value.
Calculation:[tex]\frac{speed}{fuel economy} =\frac{\frac{60 miles}{hour} }{\frac{20 miles}{gallon} } \\\frac{speed}{fuel economy}={\frac{60 miles}{hour} .{\frac{gallon}{20 miles} }\\[/tex]
[tex]\frac{speed}{fuel economy}=\frac{3 gallons}{hour}[/tex]
Inserting this 3 in the given equation 15 = 3t and including each term, we see the units cancel out:
[tex]15 gallons = \frac{3 gallons}{hour}.t(hours)[/tex]
3 is the ratio of his speed and his car's fuel economy.

Temperatures in °F can be converted in °C using the formula
C=5(F-32)/9
Make F the subject of the formula
Give your answer in the form aC+b/c where a,b and c are all positive integers
Answers
Answer:
Step-by-step explanation:
To make F the subject of the formula, you need to solve for F in the equation C = 5(F-32)/9.
You can do this by first multiplying both sides of the equation by 9 to get rid of the fraction:
C * 9 = 5(F-32)
Then, you can distribute the 5 on the right side of the equation:
C * 9 = 5F - 160
Then, you can add 160 to both sides of the equation to isolate the F term:
C * 9 + 160 = 5F
Finally, you can divide both sides of the equation by 5 to solve for F:
F = (C * 9 + 160)/5
This gives you the final form of the equation:
F = (9C + 160)/5
In this form, F is the subject of the formula. a = 9, b = 160, and c = 5 are all positive integers.
Answer:
[tex]F=\dfrac{9C+160}{5}[/tex]
Step-by-step explanation:
Given equation:
[tex]C=\dfrac{5(F-32)}{9}[/tex]
Multiply both sides by 9:
[tex]\implies 9C=5(F-32)[/tex]
Divide both sides by 5:
[tex]\implies \dfrac{9C}{5}=F-32[/tex]
Add 32 to both sides:
[tex]\implies \dfrac{9C}{5}+32=F[/tex]
[tex]\implies F=\dfrac{9C}{5}+32[/tex]
Rewrite 32 as a fraction with denominator 5:
[tex]\implies F=\dfrac{9C}{5}+\dfrac{32 \cdot 5}{5}[/tex]
[tex]\implies F=\dfrac{9C}{5}+\dfrac{160}{5}[/tex]
[tex]\textsf{Apply the fraction rule} \quad \dfrac{a}{c}+\dfrac{b}{c}=\dfrac{a+b}{c}:[/tex]
[tex]\implies F=\dfrac{9C+160}{5}[/tex]
