The graph of the function is attached below.

The graph of a function shows the correlation between its inputs (represented by x-values) and matching outputs (represented by y-values). It is a means of illustrating the actions and traits of a function.

Plotting points that conform to the function's rule in a cartesian coordinate system results in the graph of the function. An input-output pair for the function is represented by each point on the graph. The point's x-coordinate represents the input value, while its y-coordinate represents the output value.

We can further use the graph to determine the range, domain, y-intercept, x-intercept and so many others from a graph.

What is an equation?

An equation is a mathematical statement that proves two mathematical expressions are equal in algebra, and this is how it is most commonly used. In the equation 3x + 5 = 14, for instance, the two expressions 3x + 5 and 14 are separated.

125a + 65s = 1200

140a + 50s = 1230

Based on this evidence and reasoning, it is reasonable to conclude that Brianna should get the credit card, as long as she uses it responsibly and pays off her balance in full every month to avoid paying interest charges.

Percent, denoted by the symbol "%", is a way of expressing a fraction or ratio as a portion of 100. It is commonly used in everyday life to express a part of a whole or to compare quantities. Percentages can be used in various contexts, such as in finance to calculate interest rates, in statistics to represent data, and in everyday life to express discounts, tax rates, and tips. It is important to understand percentages to make informed decisions and to effectively communicate information.

Here,

CER stands for Claim, Evidence, and Reasoning, which is a framework for presenting a persuasive argument. Using this framework, we can evaluate whether Brianna should get the credit card in question:

Claim: Brianna should get the credit card.

Evidence:

The credit card has an APR of 24.99%, which is high compared to other credit cards.

The credit card has a yearly fee of $150.00.

The credit card offers 1% cash back on most purchases.

Reasoning:

While the APR and yearly fee are high, Brianna can still benefit from using the credit card to build her credit.

The 1% cash back on most purchases can help offset the cost of the yearly fee and the interest charges if she pays off her balance in full every month.

By using the credit card, such as making payments on time and not carrying a high balance, Brianna can establish a positive credit history, which can help her in the future when she wants to apply for loans or other credit cards.

The width of the river using the similar triangle is 43.3 metres.

The surveyor wants to determine the width of the river . Let's use the pair of similar triangle to find the width of the river.

Therefore, two triangles are said to be similar if their corresponding angles are congruent and the corresponding sides are in proportion.

Hence, let's find the width of the river.

Therefore,

18.6 / 34.2 = AB / 79.6

cross multiply

18.6 × 79.6 = 34.2 AB

34.2 AB = 1480.56

divide both sides of the equation by 34.2

AB = 1480.56 / 34.2

AB = 43.2912280702

The equation 3x - y = - 1; - 3x - y = 5 when solved using the elimination method is x = -1 and y = -2 respectively.

3x - y = - 1

- 3x - y = 5

Subtract the equation to eliminate y

3x - (-3x) = - 1 - 5

3x + 3x = - 6

6x = - 6

divide both sides by 6

x = -6 / 6

x = -1

Substitute x = -1 into

3x - y = - 1

3(-1) - y = -1

-3 - y = - 1

- y = - 1 + 3

-y = 2

y = -2

Therefore, the solution to the simultaneous equation is (x, y) = (-1, -2)

Answer:

\(x=21\)

Step-by-step explanation:

See attachment for triangle

The relationship between length x, length 24 and angle 30 is as follows:

\(\cos(\theta) = \frac{Adjacent}{Hypotenuse}\)

In this question;

\(Adjacent = x\)

\(Hypotenuse= 24\)

\(\theta = 30\)

Substitute these values in the above expression,

\(\cos(30) = \frac{x}{24}\)

Multiply through by 24

\(24 * \cos(30) = \frac{x}{24} * 24\)

\(24 * \cos(30) = x\)

Reorder:

\(x = 24 * \cos(30)\)

\(x = 24 * 0.8660\)

\(x = 20.784\)

The required probability is 0.970 (approx.) or 97/100 (in fraction).

Given that 69% of people in a large population have been vaccinated. We are required to determine the probability of at least one person being vaccinated if three people are randomly selected. Let's solve it using the complement rule.

The complement rule states that the probability of an event occurring is equal to 1 minus the probability of that event not occurring. That is, if A is an event, then P(A) = 1 - P(A').

We can solve the given problem using the complement rule as follows: Let P(A) be the probability of at least one person being vaccinated.

Then, the probability of no one being vaccinated is P(A') = (100 - 69) = 31%.

To find the probability of at least one person being vaccinated, we can subtract the probability of none of them being vaccinated from 1. That is, P(A) = 1 - P(A') = 1 - 0.31 × 0.31 × 0.31 = 1 - 0.029791 = 0.97021.

Hence, the probability of at least one person being vaccinated if three people are randomly selected is 0.97021 (rounded to 3 decimal places).

Therefore, the required probability is 0.970 (approx.) or 97/100 (in fraction).

Answer:

Tom paints the fence in 24 hours and Bill paints the fence in 12

Step-by-step explanation:

T = 1 fence / x hours

B = 1 fence / x - 12 hours

B + T = 1 fence / 8 hours

( 1 fence / x - 12 hours ) + ( 1 fence / x hours ) = 1 fence / 8 hours

( 1 / x - 12 ) + ( 1 / x ) = 1 / 8

multiply through all the denominators to get:

8x + 8 (x - 12 ) = x( x - 12 )

8x + 8x - 96 = x^2 - 12x

combine like terms to get:

x^2 - 28x + 96 = 0

factor to get:

( x - 4 ) ( x - 24 ) = 0

x = 4, 24

The probability of the hotel purchasing no defective sets is 2/7, the probability of purchasing 1 defective set is 4/7, and the probability of purchasing 2 defective sets is 1/7.

To find the probability distribution of x, we need to consider all possible combinations of 3 sets that the hotel can purchase from the shipment of 7 sets.

The total number of ways to choose 3 sets from 7 is given by the binomial coefficient C(7, 3) = 35.

Now, let's consider the different possible values of x.

If the hotel purchases 0 defective sets, then it must choose 3 sets from the 5 non-defective sets, which can be done in C(5, 3) = 10 ways. The probability of this occurring is:

P(x=0) = C(2, 0) * C(5, 3) / C(7, 3) = 10/35 = 2/7

If the hotel purchases 1 defective set, then it must choose 2 non-defective sets and 1 defective set, which can be done in C(2, 1) * C(5, 2) = 20 ways. The probability of this occurring is:

P(x=1) = C(2, 1) * C(5, 2) / C(7, 3) = 20/35 = 4/7

If the hotel purchases 2 defective sets, then it must choose 1 non-defective set and 2 defective sets, which can be done in C(2, 2) * C(5, 1) = 5 ways. The probability of this occurring is:

P(x=2) = C(2, 2) * C(5, 1) / C(7, 3) = 5/35 = 1/7

Therefore, the probability distribution of x is:

x | 0 | 1 | 2

P(x) | 2/7 | 4/7 | 1/7

Note that the sum of these probabilities is 1, as it should be for a probability distribution.

Answer:

P(A) = 0.57 (rounded to two decimal places).

Step-by-step explanation:

The probability of selecting a red marble from the hat can be found by dividing the number of red marbles by the total number of marbles:

P(red) = number of red marbles / total number of marbles

P(red) = 20/35

We can simplify this fraction by dividing both the numerator and denominator by 5:

P(red) = 4/7

So the probability of selecting a red marble from the hat is 4/7, or approximately 0.57 when rounded to two decimal places.

Therefore, P(A) = 0.57 (rounded to two decimal places).

Answer:

Step-by-step explanation:

we are given the ratio of students and teachers:

\( \displaystyle \: \frac{21}{4} \)

which means if the number of students is 21 then the number of teachers should be 4

to find how many teachers should go if students 84 we have to divide 84 by \(21/4\) :

\( \displaystyle \: 84 \div \frac{21}{4} \)

simplify division:

\( = \displaystyle \: 84 \times \frac{4}{21} \)
