It is just a way of describing a set.

You put the set in braces (sometimes called curly brackets), {}, which is a typical way to show that you are talking about sets.

Here are a few examples:

{x| x > 0} This is read: The set of all x such that x is greater than 0.

Reading it character by character:

{ — shows you that we are talking about a set, and it sort of opens up, or starts the set

x — tells you that we are talking about a set of elements x

| (and a : is also used sometimes) — such that (this is just notation). This says that you are about to be given to rule to see what “rule” or characteristic the x’s will have.

x > 0 — This just says what characteristics x must have to be in this set. So 7, 1/2, .3 and pi are all in this set, while -1, 0, -radical(2) are not.

So this example is just how you would use set builder notation to talk about the set “the positive real numbers”

So why use it? Because it can describe more complicated sets much more succinctly.

2. {3n + 1 | n is an element of the natural numbers} (and this could be written more succinctly if I used certain symbols) would be the set {4, 7, 10, 13, …}

3. {n^2 + n + 1 | n is an element of the natural numbers} would be the set {3, 7, 13, 21, …} and notice here, if you didn’t see the set builder notation, you might have trouble knowing what the next term in the set was.

Answer:

x = -16

Step-by-step explanation:

The angles are corresponding angles and when the lines are parallel, corresponding angles are equal.

8x+260 = 132

Subtract 260 from each side.

8x+260-260 = 132-260

8x = -128

Divide each side by 8.

8x/8= -128/8

x = -16

Answer:

x = -16

Step-by-step explanation:

We know that, corresponding angles in parallel lines are equal.

Accordingly,

8x + 260 = 132

Subtract 260 from each side.

8x = 132 - 260

8x = -128

Divide both sides by 8.

x = -16

Answer:

67

Step-by-step explanation:

Your brother is three years younger than you, so when you're 70, he'll be three years younger, 67.

~theLocoCoco

Answer:

35 years old

Step-by-step explanation:

Since your brother is half your age, that means it should be exact. 70 is not a number than would have an even split, so you would have to have either an odd number such as 5. 40 plus 40 is 80, which is to high. 30 plus 30 is 60, too low. 35 plus 35 is 70 exact. Hope this helped! Also, I dont know if this was trick question, either way, he should be half. So if you were 10, he would be 5. If you were 18, he would be 9.

Using the arrangements formula, it is found that the number is in position 697.

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

The number of possible arrangements of n elements is given by:

\(A_n = n!\)

In this problem, the numbers are sorted as:

Number of elements which we do not start with 8.

Thus:

\(n = 5 \times 5! = 600\)

Numbers that start with 8, and the second element is not 7.

Thus:

\(n_2 = 4 \times 4! = 96\)

Total:

\(600 + 96 = 696\)

872456 is the first number which starts with 87, thus it is at position 697.

Answer: 27

Step-by-step explanation:

The interest receive for a simple interest account after t years is given by:

where P is the princial (the amount invested), r is the interest rate in decimal form and t is the time.

Let x be the amount invested in the first account which has a 7% interest rate, the interest given for this account is:

We know that in the second account the investment is 193 more than two times the amount that the investment of the first account, this means that in the second account the principal is 2x+193, then the interest in this account which has a 9% interest rate is:

We know that the sum of the interest is $442.62 then we have:

Once we know the value of x we can plug it in the expression for the pincipal in the second account:

Therefore, Sang invested $1709 in the 7% account and $3611 in the 9% account.

y = 20x + 200

y = 20(1) + 200

y = 20 + 200

y =220       money deposited.

After 2 months:

y = 20x + 200

y = 20(2) + 200

y = 40 + 200

y =240 money deposited.

After 3 months:

y = 20x + 200

y = 20(3) + 200

y = 60 + 200

An exact number that shows a percentage of a total is called a fraction. You may figure it out by dividing a sum by the quantity of parts. As an example, the number 12 represents one-half of a whole number or an object. Simple subtraction of the smaller numerator from the larger numerator will yield the solution to the problem. To solve, for instance, 6/8 - 2/8, just take 2 out of the answer. The answer, which can be abbreviated to "4/8," is 12, or 12.

A height with a z-score of 1 is the lowest, a height with a percentile rank of 80 percent is in the middle, and a height at the third quartile Q₃ is the highest.

A bell-shaped distribution is also known as a normal distribution. It is a symmetrical distribution where the mean, median, and mode are all equal. The distribution has two tails that extend out from the mean in either direction. A height with a z-score of 1 is the lowest because a z-score of 1 is one standard deviation below the mean. A height with a percentile rank of 80 percent is in the middle because it is the 80th percentile, meaning that 80 percent of the data is lower than it. A height at the third quartile Q₃ is the highest because it is the 75th percentile, meaning that 75 percent of the data is lower than it. In ascending order, the heights arranged are III, II, and I.

The simulation using random digits is an illustration of sample space and probability

From the question, we understand that the simulation is to determine the probability that she picks at least one green marble in her next two picks.

One of the ways this can be done is as follows:

The above ensures that the probability of picking a green marble in each selection is 0.5 and the probability of not picking a green marble in each selection is also 0.5 i.e. the experiment is fair

Next, is to run a simulation of 10 trials.

Take for instance, the result of the simulation is as follows:

00 65 36 48 55

19 34 87 13 90

The number of outcomes that has at least one of digits 0 - 4 represents the required outcome i.e. picking at least one green marble

From the simulation result, the number of outcomes is

At least 1 green marble = 7

Number of trials = 10

So, the probability of picking at least a green marble is:

P = 7/10

P = 70%

The exact solutions of the Quadratic equation x^2 - 3x - 5 = 0 are:

x = (3 + √29) / 2 ,x = (3 - √29) / 2. The correct answer choice is:

x = the quantity of 3 plus or minus the square root of 29 all over 2.

The exact solutions of the quadratic equation x^2 - 3x - 5 = 0 using the quadratic formula, we can identify the values of a, b, and c, and substitute them into the formula:

a = 1

b = -3

c = -5

Now, we can apply the quadratic formula:

x = (-b ± √(b^2 - 4ac)) / (2a)

Substituting the values into the formula:

x = (-(−3) ± √((−3)^2 - 4(1)(−5))) / (2(1))

x = (3 ± √(9 + 20)) / 2

x = (3 ± √29) / 2

Therefore, the exact solutions of the quadratic equation x^2 - 3x - 5 = 0 are:

x = (3 + √29) / 2

x = (3 - √29) / 2

The correct answer choice is:
