Refer to the table above. Determine the marginal distribution of Gender. In paragraph form, how you calculated the marginal distribution. Include your calculations in your explanation.
Answers
The likelihood of an occurrence regardless of the result of another variable is known as marginal probability.
What is marginal probability?The likelihood of an occurrence regardless of the result of another variable is known as marginal probability. The likelihood of one event occurring in the presence of another is known as conditional probability.
We already know that marginal probabilities are calculated by dividing marginal frequencies by total frequency.
As a result, in this situation, the gender's marginal probability distribution is given by,
P(Gender=x) ≈ 0.5308 if x = Male
≈ 0.4692(1-0.5308) if x = female
= 0 otherwise

Step-by-step explanation:
Given:
A kitchen shop sells bowls in sizes small, medium and large.Draw a Venn diagram with 3 intersecting circles. Label each circle:
S = small bowlsM = medium bowlsL = large bowls----------------------------------------------------------------------------------------------
Given:
5 people bought all three sizes of bowl.Enter "5" in the central overlapping section of the Venn diagram.
----------------------------------------------------------------------------------------------
Given:
7 people bought a small bowl and a large bowl.We know that 5 people bought all 3 bowls, so to find the number who bought a small and large bowl (but not a medium bowl):
⇒ 7 - 5 = 2
Enter "2" in the section S and L but not M.
----------------------------------------------------------------------------------------------
Given:
In total, 27 people bought a small bowl, of which 12 also bought a medium bowl.First, calculate the number of people who bought only a small and medium bowl (but not a large bowl). We know that 5 people bought all 3 bowls, so subtract 5 from 12.
Enter "7" in the section S and M but not L
A total of 27 people bought a small bowl, so to find the number who bought a small bowl only (not a medium and/or large bowl), subtract the other found numbers from 27:
⇒ 27 - 5 - 2- 7 = 13
Enter "13" in the S only section.
----------------------------------------------------------------------------------------------
Given:
In total, 66 people bought a medium bowl, of which 15 also bought a large bowl.First, calculate the number of people who bought only a large and medium bowl (but not a small bowl). We know that 5 people bought all 3 bowls, so subtract 5 from 15.
Enter "10" in the section M and L but not S
A total of 66 people bought a medium bowl, so to find the number who bought a medium bowl only, subtract the other found numbers:
⇒ 66 - 5 - 7 - 10 = 44
Enter "44" in the M only section.
----------------------------------------------------------------------------------------------
Given:
On a given day, 100 people each bought at least one bowl from the shop.To find "L only" subtract all the known numbers from 100:
⇒ 100 - 5 - 2 - 7 - 13 - 10 - 44 = 19
Enter "19" into the L only section.
----------------------------------------------------------------------------------------------
Finally, to work out the total number of people that bought a large bowl, add up the numbers in the L circle:
⇒ 2 + 5 + 10 + 19 = 36

F(x, y, z) = yzi 9xzj exyk, c is the circle x2 y2 = 9, z = 1
Answers
The value of curlF.dS is 72π if the F(x, y, z) = yzi 9xzj exyk, c is the circle x2 y2 = 9, z = 1
What is integration?It is defined as the mathematical calculation by which we can sum up all the smaller parts into a unit.
We have:
[tex]\rm F(x, y, z) = yzi+ 9xzj+ e^{xy}k[/tex]
And curl is x²+y²= 9 and z =1
In the parametric form:
[tex]\rm \vec{r}(t) = 3cost \vec{i}+3sint \vec{j}+\vec{k}[/tex] 0 ≤ t ≤ 2π
First two component represent the circle and last one represent the z =1
Using Stoke's theorem:
[tex]\rm \int\limits\int\limits_S {curl \ \ve{F}.d\vec{S}} = \int\limits_C {\vec{F}} \, .d\vec{r } = \int\limits^{2\pi}_0 {\fec{F}(\vec{r}(t)).\vec(r)t} \, dt[/tex]
Here:
[tex]\rm \vec{F}(\vec{r}(t)) = 3sint \vec{i}+27cost \vec{j}+e^{cost.sint}\vec{k}[/tex]
Now calculate the dot product of curl F and dS we get:
[tex]\rm \int\limits\int\limits_S {curl \ \ve{F}.d\vec{S}} = \int\limits^{2\pi}_0 (-9sin^2t+81cos^2t)dt[/tex]
After solving the above integral, we will get:
[tex]\rm \int\limits\int\limits_S {curl \ \ve{F}.d\vec{S}} = 72\pi[/tex]
Thus, the value of curlF.dS is 72π if the F(x, y, z) = yzi 9xzj exyk, c is the circle x2 y2 = 9, z = 1

same size box. The dimensions of the box are shown to the right
A Find the volume of the box to see how much space is available to place
packages. Show your work
B. How much wrapping paper is needed to wrap ONE box? Show your
work
If there is only 160 square feet of wrapping paper left, will the employee
be able to wrap all of the gifts? Explain.
Answers
The area A of a rectangle is A = bh, where b is the base of the rectangle and h is the height. The area of each rectangle with side lengths 1.5 ft and 2 ft is 1.5 × 2 = 3ft2. Since there are two rectangles with these dimensions, the combined area is 2 × 3 = 6 ft2. The area of each rectangle with side lengths 1.5 ft and 2.5 ft is 1.5 × 2.5 = 3.75 ft2. The area of each rectangle with side lengths 2 ft and 2.5 ft is 2 × 2.5 = 5 ft2. Since there are two rectangles of each type, the combined area is 2 × 3.75 + 2 × 5 =17.5 ft2. So, the total surface area of the box is 6 ft2+ 17.5 ft2 = 23.5 ft2
Part B:
The employee needs to wrap 8 boxes, each with a surface area of 23.5 ft2. So, the combined surface area needing to be wrapped is 8 × 23.5 = 188 ft2. Since there is only 160 square feet of wrapping paper left, the employee will not be able to wrap all of the gifts

Answers
The degree of the polynomial f(x) = 2x(x - 3)³(x + 1)(4x - 2) is 6, and the dominant term is - 216x²
The degree of the polynomial?The polynomial function is given as:
f(x) = 2x(x - 3)³(x + 1)(4x - 2)
To determine the degree, we simply add the multiplicities.
So, we have:
Degree = 1 + 3 + 1 + 1
Evaluate
Degree = 6
Hence, the degree of the polynomial is 6
The dominant term of the polynomialWe have:
f(x) = 2x(x - 3)³(x + 1)(4x - 2)
Expand
f(x) = 8x⁶ - 68x⁵ + 176x⁴ - 72x³ - 216x² + 108x
The term with the highest absolute value is - 216x²
Hence, the dominant term is - 216x²

n=713, p= 4/5
Answers
Answer:
μ - 2σ = 549.04μ + 2σ = 591.76Step-by-step explanation:
Given the parameters of binomial distribution
n = 713, p = 4/5We need to find the mean μ and the standard deviation σ to calculate required values
Follow the steps below1. Find the mean
μ = n·p = 713*(4/5) = 570.42. Find the variance
σ² = np(1 - p) = 713*(4/5)*(1 - 4/5) = 114.083. Find the standard deviation
σ = √114.08 = 10.68 (rounded)Find the minimum usual value
μ - 2σ = 570.4 - 2*10.68 = 549.04Find the maximum usual value

or, (x-13)(x-7)= 0
either,
x-13=0 ==> X= 13
x-7=0 ==> X = 7
sum of all positive values of x = 13 +7 = 20The sum of all positive values of x such that x² + 6x - 91 = 0 is 20
What is quadratic equation?A quadratic equation is a second-order polynomial equation in a single variable x , ax2+bx+c=0. with a ≠ 0 .
The given equation is x² + 6x - 91 = 0
x² + 13x - 7x -91=0
