a. not a 10-peso coin.

b. a 5-peso coin.

Answers

Answer 1

a. The probability that it is not a 10-peso coin is  [tex]\frac{12}{17}[/tex].

b. The probability that it is a 5-peso coin is [tex]\frac{3}{17}[/tex] .

What is probability?

The mathematical notion of probability is used to determine the likelihood of an event. It is only helpful for estimating the likelihood that an event will happen. A scale from 0 to 1, where 0 denotes impossibility and 1 denotes a specific occurrence.

We are given that a purse contains five 10-peso coins, three 5-peso coins, and nine 1-peso coins.

Total coins = 5 + 3 + 9 = 17

a. Probability of getting a 10 peso coin is

P (A) = [tex]\frac{5}{17}[/tex]

Probability of not getting a 10 peso coin is

⇒Probability = 1 - P (A)

⇒Probability = 1 - [tex]\frac{5}{17}[/tex]

⇒Probability = [tex]\frac{12}{17}[/tex]

b. Probability of getting a 5 peso coin is [tex]\frac{3}{17}[/tex] .

Hence, the required probabilities have been obtained.

How to explain the information

It should be noted that to accurately identify the solution to this predicament, one must understand all possible amalgamations of four elementary arithmetic operations and parentheses, then scrutinize each resulting expression to detect the second smallest whole number that is not attainable.

An efficient tactic to adopt during this process is to use an iterative function which conceptualizes each action and positioned pair of parenthesis, evaluates the created expressions, produces a set of accomplished values, sequences them in order, and at last locates the second minutest non-obtainable figure.

Help! Does the rule represent an exponential function?

y = -5x^7

Answers

No, the rule y = -5x^7 does not represent an exponential function.

An exponential function is a function where the independent variable appears in the exponent. The general form of an exponential function is y = ab^x, where a and b are constants.

In the given function y = -5x^7, the independent variable x appears as a power, but it is not in the exponent of a constant base. Therefore, this function does not represent an exponential function.

Instead, the given function is a polynomial function of degree 7, where the highest power of the independent variable x is 7.

Explain why the nature of roots depends on the value of the dicriminant.​

Answers

Answer:

The discriminant of a quadratic equation is the expression found under the square root sign in the quadratic formula, which is b^2 - 4ac. The discriminant reveals information about the nature of the roots of the equation.

If the discriminant is positive, the quadratic equation has two distinct real roots. This means that the equation can be factored into two linear factors, each of which can be set equal to zero to solve for the roots.

If the discriminant is zero, the quadratic equation has one real root, which is a repeated root. This means that the equation can be factored into a linear factor that occurs twice.

If the discriminant is negative, the quadratic equation has two complex (non-real) roots, which are conjugates of each other. This means that the equation cannot be factored into two linear factors with real coefficients.

In summary, the nature of roots of a quadratic equation is determined by the value of the discriminant, which depends on the coefficients of the quadratic equation.

According to this disparity, his batting average is larger than or equal to inequality 0.300, which meets the requirement that it be equal to or higher than the league average.

What is inequality?

A connection between two expressions or values that is not equal is known as an inequality in mathematics. Inequality follows imbalance, therefore. In mathematics, an inequality makes a connection between two values that are not equal. Egality and inequality are different. The not equal symbol is often used to indicate that two values are not equal (). Various inequalities are employed to contrast values of all sizes. By changing the two sides until just the variables are left, one may solve many straightforward inequalities. However a variety of factors support inequality: Negative values are split or added on either side. Switch between the left and right.

Oliver's batting average is at or above the league average of 0.300, hence the following inequality would be the most accurate way to describe it:

The median of the data 10 16 12 15 7 is

Answers

To find the median of a set of data, you need to arrange the values in order from least to greatest and then find the middle value. If there are an odd number of values, the median is the middle value. If there are an even number of values, the median is the average of the two middle values.

So, for the data set 10, 16, 12, 15, 7, we can arrange the values in order from least to greatest:

7, 10, 12, 15, 16

Since there are an odd number of values, the median is the middle value, which is 12. Therefore, the median of the data 10, 16, 12, 15, 7 is 12.

Can someone explain me how to do this task please? Thank you

Answers

Step-by-step explanation:

common multiples are numbers that can be divided without remainder by both numbers.

12. 3 and 5

3 and 5 are both prime numbers, so their common multiple are multiples of their product (3×5 = 15).

so,

1×15 = 15

2×15 = 30

3×15 = 45

13. 4 and 6

the prime factors of 4 are

2×2

the prime factors of 6 are

2×3

the last common multiple is the product of the longest chains of prime factors of the numbers :

2×2 × 3 = 12

6 has only one 2 factor, 4 has two 2 factors, so that is the longest chain. and 6 has one 3 factor, which makes it the longest chain for that.

the multiples for 4 and 6 and now the multiples of 12 :

1×12 = 12

2×12 = 24

3×12 = 36

4×12 = 48

14. 3 and 7

they are both again prime numbers, so we are looking for multiples of their product (3×7 = 21).

1×21 = 21

2×21 = 42

16.

as before.

2/3 = 4/6 = 6/9 = 8/12

17.

as before

4/5 = 8/10 = 12/15 = 16/20

18.

now we need to find the largest n/n factor hidden in the fraction. by eliminating that we get the core (simplified) value of the fraction.

4/12 = 1/3 × 4/4

Triangles are important in geometry and have various types based on their sides and angles, such as equilateral, isosceles, scalene, acute, right, and obtuse triangles.

Given:- triangle ABC and DEF are similar.

So , AC = DF

Therefore,

4x-23 = 2x+2

4x – 2x = 2 + 23

2x = 25

x = 25/2 = 12.5

therefore, AC = 4x – 23

                        = 4 * 12.5 – 23

                        = 50 – 23

                       AC =27

So ,From triangle DEF

EF = 2x-2

what is proportionality?

Proportionate relationships are those that have the same ratio every time. For example, the average number of apples per tree defines how many trees are in an orchard and how many apples are in an apple harvest. Proportional refers to a linear relationship between two numbers or variables in mathematics. When the first quantity doubles, the second quantity doubles as well. When one of the variables decreases to 1/100th of its previous value, the other falls as well. When two quantities are proportional, it means that as one rises, the other rises as well, and the ratio between the two remains constant at all levels. The diameter and circumference of a circle serve as an example.

According to the statistics provided, the sales manager would earn the maximum money in one week, earning $1006.25 for 35 hours of labor at a cost of $28.75 per hour.

If 9% of a number equals 10, find 27% of that number.

Answers

Answer: 27% of the number is 30.

Step-by-step explanation:

Let's start by setting up an equation to solve for the number:

0.09x = 10

Here, x represents the number we are trying to find. To solve for x, we can divide both sides of the equation by 0.09:

x = 10 ÷ 0.09

x = 111.11...

So the number we are looking for is approximately 111.11.

To find 27% of this number, we can multiply it by 0.27:

27% of 111.11... = 0.27 × 111.11...

27% of 111.11... = 30

Therefore, 27% of the number is 30.

Figure KLMN is congruent to Figure QRST because rigid motions can be used to map Figure KLMN onto Figure QRST.

Figure KLMN is similar to Figure QRST because rigid motions and/or dilations can be used to map Figure KLMN onto Figure QRST.

Since the figures are similar, the scale factor is 2.

What are similar geometric figures?

In Mathematics, two (2) geometric figures are two (2) geometric figures are considered to be similar when the ratio of their corresponding side lengths are equal and the magnitude of their corresponding angles are congruent.

Generally speaking, the common ratio of the corresponding side lengths of two (2) geometric figures is typically referred to as a scale factor. Since the given pair of geometric figures is similar, we can calculate the scale factor that maps Figure KLMN onto Figure QRST as follows:

Scale factor = TQ/NK

Scale factor = 10/5

Scale factor = 2.
