Suppose X and Y are non-empty sets. Which set contains more elements: X U Y or X ∩ Y? Explain.

Answers

Answer 1

Answer:

The union of two sets is guaranteed to result in an equal or larger set than if they were intersected.

This only makes sense because intersecting sets is exceptional, only values that already exist in both sets are in the result.  Whereas a union of two sets gives you all of the content of both.

The only time when an intersection is even equal to a union is when the two sets are identical.  If they aren't then the intersection will be smaller.

Answers

Answer:

LCD = (x - 7)(x + 3)(x + 2)(x - 2)

Step-by-step explanation:

First, we factor each polynomial.

x^2 - 4x - 21 = (x - 7)(x + 3)

x^2 - 4 = (x + 2)(x - 2)

There are 4 different factors and none are in common, so the LCD is the product of all the factors.

Ann had 48 fliers to post around town. Last week, she posted 2/3 of them. This week, she posted 3/8 of the remaining fliers. How many fliers has she still not posted?

Answers

Answer:

Ann had 48 fliers to post around town

Last week, she posted 2/3 of them

[tex]48 \times \frac{2}{3} = 32 \\ [/tex]

Therefore, she should posted 32 fliers

This week, she posted 3/8 of the remaining fliers

[tex]48 \times \frac{3}{8} = 18 \\ [/tex]

Therefore, she should posted 18 fliers

Total fliers she should post are (32+18)=50 fliers

She still did not post (50-48)= 2 fliers

2 fliers is the right answer.

Which equation will solve the following word problem? One small pitcher and one large pitcher can hold 12 cups of water. If the large pitcher is twice the size of the small pitcher, how much does the small pitcher hold?


S = 12/2S


2S = 12/S


2S + S = 12


2S - S = 12

Answers

Option 3
Amount of water hold by both the pitchers (Large + small) = 12 cups
Let the small pitcher holds the water = S cups
If the water hold by the large pitcher is twice the size of the small pitcher, then the amount of water hold by large pitcher = 2S
Total amount water hold by both = S + 2S
Equation for this situation will be,
S + 2S = 12
Therefore, Option (3) will be the answer.

Step-by-step explanation:

volume of cuboid=l×b×h=11×2×19=418c³

Answer:

418 square centimeters.

Step-by-step explanation:

Since the formula for volume is length times width times height, you would have to multiply 11 (length) times 2 (width) first, and you would get 22. Next, you have to multiply 22 with the height (19). After you do this you will get your final answer which is 418 square centimeters.

Which set of shapes can be arranged in 6 equal groups, with no shapes left
over?

Answers

The set of shapes that can be arranged in 6 equal groups is the first set or the set of triangles.

What does it mean to arrange with no shapes left over?

This task requires you to arrange or divide the shapes in equal groups of 6 and once the shapes are divided there can not be any shape leftover. Let's look at some examples:

20 apples divided between 5 people = 4 apples4 apples x 5 people = 20 (there are no apples leftover)20 apples divided between 6 people = 3 apples3 apples x 6 people  = 18 apples ( there are 2 apples left over)

What set does not leave shapes leftover?

The only set in which this occurs is the triangle set. This is because there are 12 triangles and 6 is a divisor of 12.

12 / 6 = 26 x 2 = 12

Leah plans to purchase merchandise from a department store that is valued at $100. She will use $20 in-store bucks that she has earned
plus a 30% discount coupon to reduce her final cost. What is the final cost of the items (before tax) if the $20 store bucks are applied before
the 30% discount?

Answers

subtract 20 from 100.
100 - 20 = $80
if the 30% is applied it will be
80 - 30% = $56

The final cost of the items (before tax) if the $20 store bucks are applied before the 30% discount is $76.

The discount of 30% will be applied on $80 ($100 - $20), resulting to a discount of of $24 ($80 * 30%).

This discount is subtracted from the total value of the merchandise to get the final cost as $76 ($100 - $24).

Thus, the final cost to Leah to purchase the merchandise from the department store is $76.

Using the remainder theorem see if (x-2) and (x+5) are factors of the polynomial

X^2+3x-10

Answers

Answer:

See explanations below

Step-by-step explanation:

Given the polynomial function

P(x) = X^2+3x-10

To check whether x-2 and x+5 are factor, we will find x and then show that P(x) = 0

For x-2

x - 2 = 0

x =2

P(2) = 2²+3(2)-10

P(2) = 4+6 -10

P(2) = 10-10

P(2) = 0

Since the remainder is zero, hence x-2 is a factor of the polynomial

Similarly for x+5;

x+5 = 0

x = -5

P(-5) = (-5)²+3(-5)-10

P(-5) = 25-15-10

P(-5) = 10-10

P(-5) = 0

This also shows that x+5 is a factor

For P(x) = 2x^4 – 5x^3+x-10, use synthetic substitution to evaluate P(-2). P(1), and P(2).

Answers

Answer:

P(-2) = 2(-2^4) - 5(-2^3) + (-2) -10

= 2(16) - 5(-8) + (-2) - 10

= 32+40-2-10

= 60

P(1) = 2(1^4) - 4(1^3) + (1) - 10

= 2 - 4 + 1 - 10

= -11

P(2). = 2(2^4) - 5(2^3) + (2) - 10

= 2(16) - 5(8) + 2 - 20

= 32-40+2-10

= -20
