Answer:

2.A B C =(1,3,4,5,7,8,9,12,13,14......20)

The answer is:[tex]\to \bold{(A \cup B\cup C) \cap(A\cup B\cup C) = \bold{\{1,3,4,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20 \}} }\\\\\to \bold{(A \cap B\cap C) \cap(A \cap B \cap C)=\{6, 10, 11\}}[/tex]

Before giving the solution let discuss what is the universal set, Union, and intersection:

Following are the solution to the question:

Given:

Universal set [tex]\bold{ S = \{ 1 , 2 , 3 , ... , 18 , 19 , 20 \} }[/tex]

Let

[tex]\bold{A, B, C \subset S}[/tex] i.e.

[tex]\bold{A\subset S}\\\\\bold{B\subset S}\\\\\bold{C\subset S}\\\\[/tex]

Set [tex]\bold{A = \{ 1 , 6 , 10 , 11 , 12 , 13 , 14 , 15 , 16 , 18 , 19 , 20\}}[/tex]

Set [tex]\bold{B = \{ 1 , 3 , 4 , 6 , 8 , 9 , 10 , 11 , 12 , 15 , 20 \}}[/tex]

Set [tex]\bold{C = \{ 3 , 6 , 7 , 8 , 9 , 10 , 11 , 13 , 14 , 17 \}}[/tex]

Find:

[tex]\to \bold{(A \cup B\cup C) \cap(A\cup B\cup C) =?}\\\\\to \bold{(A \cap B\cap C) \cap(A \cap B \cap C)=?}[/tex]

Solution:

In [tex]\bold{(A \cup B\cup C) \cap(A\cup B\cup C)}:[/tex]

Calculating:

[tex]\bold{(A \cup B\cup C) }= \bold{\{1,3,4,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20 \}}[/tex]

In this question, the "[tex](A \cup B\cup C)[/tex]" value is equal to "[tex]\bold{\{1,3,4,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20 \}}[/tex]" that is 18 elements.

When we intersecting both sets that is[tex]\bold{(A \cup B\cup C) \cap(A\cup B\cup C)}[/tex] so, its value will be the same that is:

"[tex]\bold{\{1,3,4,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20 \}}[/tex]" .

In [tex]\bold{(A \cap B\cap C) \cap(A \cap B \cap C):}[/tex]

Calculating:

[tex]\bold{(A \cap B\cap C) }= \bold{\{6, 10, 11, \} }[/tex]

In this question, the "[tex]\bold{(A \cap B\cap C) }[/tex]" value is equal to "[tex]\bold{\{6, 10, 11 \} }[/tex]" that is 3 elements.

When we intersecting both sets that are [tex]\bold{(A \cap B\cap C) \cap(A \cap B \cap C):}[/tex] so, its value will be the same that is:

"[tex]\bold{\{6, 10, 11 \} }[/tex]".

So, the final answer is:[tex]\to \bold{(A \cup B\cup C) \cap(A\cup B\cup C) = \bold{\{1,3,4,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20 \}} }\\\\\to \bold{(A \cap B\cap C) \cap(A \cap B \cap C)=\{6, 10, 11\}}[/tex]Learn more:

The third week they sold $375 in bumper stickers

Step-by-step explanation:

Proportions and Percentages

During the first week, the civic group sold 500 bumper stickers as a fundraiser.

During the second week. they sold 50% more bumper stickers than the first week. First, we calculate the increment of 50% of 500:

50% 500 = 50 * 500 / 100 = 250

Thus the second week they sold:

500 + 250 = 750 bumper stickers

Now we know the third week they sold 50% fewer than the second week.

Again, we calculate the 50%, but this time on the basis of 750, and not 500 bumper stickers:

50% 750 = 50 * 750 / 100 = 375

Thus the third week they sold:

$750 - $375 = $375

The third week they sold $375 in bumper stickers

The answer is "confidence interval".

Step-by-step explanation:

The trust period is a set of values that may include confidence intervals unspecified. Whenever a representative selection is collected numerous times, its sample parameter would be a certain percentage of its confidence intervals. It shows how likely the position of a statistical parameter will be estimated.

Answer:

There were 130 hamburgers sold on Friday

Step-by-step explanation:

Assume that the number of hamburgers sold is x

∵ The number hamburgers sold = x

∵ The number of cheeseburgers sold was two times the number of

   hamburgers sold

∴ The number of cheeseburgers sold = 2x

∵ On Friday, the shop sold a combined total of 390 hamburgers and

    cheeseburgers

→ Add x and 2x, then equate the sum by 390

∴ x + 2x = 390

→ Add the like terms

∴ 3x = 390

→ Divide both sides by 3

∵ [tex]\frac{3x}{3}[/tex] = [tex]\frac{390}{3}[/tex]

∴ x = 130

∵ x represents the number of hamburgers

∴ There were 130 hamburgers sold on Friday

Answer:

[tex]7+w \ge 21[/tex]

remove the line under the arrow

Answer:

w>14

Step-by-step explanation:

"sum" means adding together. So, the sum of 7 and w would be 7+w. The equation states that this sum is greater than 21, so:

7+w>21

if you want a simplified version, subtract 7 from both sides to get w>14

Answer:

B. It will be the tens place because 6 is greater than 3.

Step-by-step explanation:

Since the question said "quotient," then I believe we have 362 ÷ 6 and not "362 + 6."

If we work on the quotient we have

[tex]60\frac{1}{3}[/tex]

Obviously, the first digit in the quotient is 6 and it takes the place of tens.

Looking at the options, option B fits the most because 6 is actually greater than 3.

Therefore, the answer is option B, It will be the tens place because 6 is greater than 3.

4p^3 (4p + 1)

Step-by-step explanation:

All we can do with this equation is factor it.

16p^4 + 4p^3  

When we look at the coefficients, there is a common factor of 4 with 16 and 4. The p's are also common factors, and we can take out a common factor of x^3. We can combine these common factors and take them out of the equation at the same time.

4p^3 (4p + 1)

Answer:

3 oz

Step-by-step explanation:

Let x represent the number of oz. of the medal with 40% gold:

Set up an equation and solve for x:

0.4x + 7(0.9) = 0.75(x + 7)

0.4x + 6.3 = 0.75x + 5.25

6.3 = 0.35x + 5.25

1.05 = 0.35x

3 = x

So, you will need 3 oz. of the metal with 40% gold

Answer:

Therefore, the solution of the system of equations will be:

[tex]x=5,\:y=-1[/tex]

Step-by-step explanation:

Given the system of equations

[tex]x-y=6;\:y=-1[/tex]

solving

[tex]\begin{bmatrix}x-y=6\\ y=-1\end{bmatrix}[/tex]

[tex]\mathrm{Subsititute\:}y=-1[/tex]

[tex]\begin{bmatrix}x-\left(-1\right)=6\end{bmatrix}[/tex]

[tex]\begin{bmatrix}x+1=6\end{bmatrix}[/tex]

Isolate x for [tex]x+1=6[/tex]

[tex]x+1=6[/tex]

[tex]x=5[/tex]

Therefore, the solution of the system of equations will be:

[tex]x=5,\:y=-1[/tex]

Determine the capacity of the aquarium

This question implies that, we calculate the volume of the prism and this is calculated by multiplying the dimensions of the aquarium. i.e.

[tex]Volume = Length * Width * Height[/tex]

Substitute values for the dimensions

[tex]Volume = 10 * 20 * 10[/tex]

[tex]Volume = 2000\ in^3[/tex]

Hence, the volume of the aquarium is 2000 cubic inches
