Answer: {-3, 7, 18}

Step-by-step explanation:

B ∪ C = {-3, -1, 5, 7, 9, 18}

A ∩ (B∪C) = {-3, 7, 18}

please give me a brainliest answer

Answer:

Step-by-step explanation:

First we look at PEMDAS.

In A∩(B∪C), parentheses come first.

So, we do B∪C.

The ∪ symbolizes union, which means you have to combine the elements of the two sets.

If B={−1,5,7,18}, and C={−3,5,9}, then both of them together is {-3,−1,5,7,9,18}. I used underlining and italics to show where the numbers came from. There is a 5 in both sets, but you only have to put it once.

B∪C={-3,−1,5,7,9,18}.

Now that we have B∪C, we can solve for A∩(B∪C).

∩ means intersection, so you find the elements in both sets. Basically, just look for numbers that appear in both A and B∪C.

B∪C={-3,−1,5,7,9,18}

A={0,12,-3,7,18}

Therefore, A∩(B∪C)={-3, 7, 18}

Answer:

3) 2

4) Water's Edge Rafts

Step-by-step explanation:

3) Rate of change is nothing but the slope

Slope formula : y2 - y1 / x2 - x1

13 - 11 / 2 - 1

2/1

2

Rate of change = 2

4) Rate of change : y2 - y1 / x2 - x1

Water's Edge Rafts

Answer:

The number generator is fair. It picked the approximate percentage of white socks most of the time.

Step-by-step explanation:

Just took the test :3

Description  about the number generator : The number generator is fair. It picked the approximate percentage of white socks most of the time.

Random selection is a part of the sampling technique in which each sample has an equal probability of being chosen.

According to question

White socks = 80%

Black socks = 20%

Randomly selecting 10 socks from the drawer .

Process repeated 10 times

According to dots on plot

Number white socks was selected in each round is   7,7,7,8,8,8,8,9,9,9 .

If we evaluate the number generator :

80% of the socks are white, and each trial selects 10 socks.  80% of 10 is 8, which is what the number generator picked most of the time.  

That means The number generator is fair.

Hence, The number generator is fair. It picked the approximate percentage of white socks most of the time.

Answer:

Each magazine would cost 5 dollars.

Step-by-step explanation:

If he originally started with $25 then spent $5 he would then have $20 dollars left.

If he then bought 4 magazines using the last of his $20 (ignoring sales tax) you would have to divide $20 by 4 to get a total of $5 dollars for each magazine.

Step-by-step explanation:

Answer:

16 ==>> Length of PR

4 ==>> Value of A

3 ==>> Value of B

6 ==>> Length of QS

Step-by-step explanation:

==>> Since PQRS is a parallelogram the diagonals are symmetrically split by a shared midpoint: T

--

==>> Thus the values of A & B can be found by setting the sides to equal each other.

2B - 3 = B [add 3 and subtract B from both sides]

B = 3

A + 4 = 2A [subtract A from both sides]

4 = A

--

==>> Then to find the length of the diagonals: Plug the variables in and add both sides.

2(3) - 3   +   (3) =6

(4) + 4     +   2(4)  =16      

The correct matching of the elements to their values are:

This refers to the plane that has four sides and their opposite sides are parallel.

Hence, because PQRS is a parallelogram, the diagonals are symmetrically split by a shared midpoint:

This means that the values of A & B can be found by setting the sides to equal each other.

2B - 3 = B

B = 3

A + 4 = 2A

4 = A

Length of the diagonals:

2(3) - 3   +   (3) =6

(4) + 4     +   2(4)  =16

Step-by-step explanation:

took review

Step-by-step explanation:

all of these 4 numbers are

integer (whole numbers positive and negative).

real (every whole number can be written as e.g. 3.0 and is part of the real numbers).

rational (as any whole number can be written as e.g. 3/1 and is part of the rational numbers).

whole (no fractions).

natural (they are in the set of [1, 2, 3, ... infinity) ).

the only thing here they are not is irrational, as to be irrational they would need to have an infinite sequence of digits after the decimal point without any repeating pattern.

Answer:

2 3/4 or 11/4

Step-by-step explanation:

2.75 = 11/4 = 2 3/4 as a fraction

To convert the decimal 2.75 to a fraction, just follow these steps:

Step 1: Write down the number as a fraction of one:

2.75 = 2.75 / 1

Step 2: Multiply both top and bottom by 10 for every number after the decimal point:

As we have 2 numbers after the decimal point, we multiply both numerator and denominator by 100. So,

2.75 / 1 = (2.75 x 100)/(1 x 100) = 275/100.

Step 3: Simplify (or reduce) the above fraction by dividing both numerator and denominator by the GCD (Greatest Common Divisor) between them. In this case, GCD(275,100) = 25. So,

(275 ÷ 25)/ (100 ÷ 25) = 11/4 when reduced to the simplest form.

As the numerator is greater than the denominator, we have an IMPROPER fraction, so we can also express it as a MIXED NUMBER, thus 275 /100

is also equal to  2 3/4 when expressed as a mixed number.

How to Convert a Decimal to a Fraction - Steps

Step 1: Write down the decimal as a fraction of one (decimal/1);

Step 2: If the decimal is not a whole number, multiply both top and bottom by 10 until you get an interger at the numerator.

Step 3: Simplify (or reduce) the fraction if it is not in the simplest form.
