Step-by-step explanation:

Given:

Draw a Venn diagram with 3 intersecting circles. Label each circle:

----------------------------------------------------------------------------------------------

Given:

Enter "5" in the central overlapping section of the Venn diagram.

----------------------------------------------------------------------------------------------

Given:

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:

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:

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:

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

Twenty percent of 76 is,

→ 20% of 76

→ (20/100) × 76

→ 1520/100

The likelihood of an occurrence regardless of the result of another variable is known as 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

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

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

Answer:

40%

Step-by-step explanation:

The concept of percent increase is basically the amount of increase from the original number to the final number in terms of 100 parts of the original. An increase of 5 percent would indicate that, if you split the original value into 100 parts, that value has increased by an additional 5 parts. So if the original value increased by 14 percent, the value would increase by 14 for every 100 units, 28 by every 200 units and so on. To make this even more clear, we will get into an example using the percent increase formula in the next section.

Answer:

60 degrees

Step-by-step explanation:

Triangle = 180 degrees

60+60+X=180

120+X=180

X=60

The degree of the polynomial f(x) = 2x(x - 3)³(x + 1)(4x - 2) is 6, and the dominant term is - 216x²

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

We 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

Binomial Probability distribution.

This is the probability of 9 tails or 10 tails being flipped.

Prob ( 10 tails) = (1/2)^10 = 1/1024

Prob ( 9 tails) = 10C9 * 1/2^9* 1/2 = 5/512

Required probability =  1/1024 + 5/512

Doing the adds first;

= 25 - 44

= -19.

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

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

The total number of boxes that can be loaded onto the trailer is 27.

Here we have to determine the maximum number of boxes.

That can be stored in a locker by the volume of one box.

From the given information volume of the box is Vb and the volume f the locker is Vl.

[tex]Volume=Length\times width\times height[/tex]

Therefore we get,

[tex]V_b=4\times3\times2\\V_b=24ft^3[/tex]

The volume of the locker is

[tex]V_L=12\times6\times 9\\V_L=684ft^3[/tex]

Therefore the number of the maximum boxes are

[tex]\frac{VL}{V_b} =\frac{648}{24} \\=27[/tex]

Therefore, The total number of boxes can be loaded onto the trailer are 27.
