What is X in this equation

Answers

Answer:

13/4 or 3.25

Step-by-step explanation:

Since they are vertical angles, they are equal to each other. Thus, set the two equations together:

8x + 32 = 12x + 19

Isolate x

32 = 12x + 19 - 8x = 4x + 19

32 - 19 = 4x

4x = 13

4x/4 = 13/4 = 3.25

If one student is chosen at random, the probability that the student was a female and got 'A' is 0.38

What is probability?

Probability is a synonym for potential. It is a field of mathematics that examines how random events happen. From zero to one, the value is expressed. To forecast the likelihood of events, probability has been introduced in mathematics.

The likelihood that something will occur is essentially what is meant by probability. This is the fundamental theory of probability, which is also used to calculate the probability distribution, and it is from it that you will learn the likelihood of various outcomes in a random experiment.

The total number of outcomes that can occur should be known before calculating the likelihood that a specific event will occur.

Total numbers of students = 53

Total numbers of females = 34

Total numbers of females of A grades = 20

So probability = 20/53

                        = 0.38

f(x)=(1/7)(7x) what is f(3)

Answers

The value obtained for f(3) after substituting x = 3 in the function f(x) is 0.0067.

What exactly is a function?

A function from a set X to a set Y assigns exactly one element of Y to each element of X. The set X is known as the function's domain, and the set Y is known as the function's codomain.

What are the Function Formulas?

The list of function formulas is divided into two categories: formulas for performing numerous arithmetic operations across functions and formulas for performing combined operations involving two or more functions.

The given function is f(x) = (1/7)/(7x)

We need to find the value of f(3) so we will substitute x = 3 in the given function as follows:

f(3) = (1/7)/(7×3)

∴ f(3) = (1/7)/21

∴ f(3) = 0.142/21

∴ f(3) = 0.0067

Therefore, after substituting x = 3 in the function f(x), the value obtained for f(3) is 0.0067.

A bird of species A, when diving, can travel four times as fast as a bird of species B top speed. If the total speeds for these two birds is 170 miles per hour, find the fastest speed of the bird of species A and the fastest speed of the bird of species B.

Answers

The fastest speed of the bird of species A is 136 mi/hr. and the fastest speed of the bird of species B is 34 mi/hr.

What is the equation?

The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.

A bird of species A, when diving, can travel four times as fast as a bird of species B at top speed which is given in the question.

Let b = the speed of bird species B.

So the speed of bird species A is 4b.

If the total speed for these birds is 170, then there is an equation :

⇒ 4b + b = 170.

⇒ 5b = 170

⇒ b = 170/5 = 34 mi/hr.

So the speed of bird species A will be 4×34 ⇒ 136 mi/hr.

Therefore, the fastest speed of the bird of species A is 136 mi/hr. and the fastest speed of the bird of species B is 34 mi/hr.

Question 3: Kylie needs to spend at least 5 hours each week practicing the piano. She has already practiced 2 and 3/4 hours this week. She wants to split the remaining practice time evenly between the last 3 days of the week. Write an inequality to determine the minimum number of hours she needs to practice on each of the 3 days.

Answers

Using proportions with mixed numbers, the inequality to determine the minimum number of hours she needs to practice on each of the 3 days is: m ≥ 3/4.

What is a proportion?

A proportion is a fraction of a total amount, and equations can be built to find the desired measures in the problem using operations such as multiplication or division.

One example is the mean of a data-set, as the mean is given by the sum of all observations in the data-set divided by the number of values.

For this problem, we have that:

She has already practiced 2.75 hours, as the decimal part is of 3/4 = 0.75, hence 2 and 3/4 = 2 + 0.75 = 2.75.She needs to practice 5 hours.

Hence the minimum number of hours that she still needs to practice is:

5 - 2.75 = 2.25 hours.

The amount is split evenly amount the 3 days, hence the lower bound of the inequality is:

2.25/3 = 0.75 = 3/4.

Hence the amount is given by:

m ≥ 3/4.

The linear function m = 50 - 9d represents the amount m (in dollars) of money you have
left after buying d DVDs.
a. Interpret the terms and coefficient in the equation.
b. Find the domain of the function. Is the domain discrete or continuous? Explain.
c. Graph the function using its domain.

Answers

       A linear equation is an algebraic equation of the form y=mx+b, where m is the slope and b is the y-intercept, and only a constant and a first-order (linear) term are included. The variables in the preceding equation are y and x, and it is occasionally referred to as a "linear equation of two variables."

How can you tell whether a domain is continuous or discrete?

         A domain's discreteness or continuousness can be determined by examining the function's graph. The domain is continuous if the graph is a line. The domain is discrete if the graph consists of a collection of points.

What is a discrete domain example?

Private Domain

      The values that will be effective for the function are distinct from one another. The maximum number of children you can have, for instance, has a defined answer. You can have 0 children, 1, 2, 3, etc., but not 2,34.

How can you determine a discrete function's domain?

      Discrete graphs are those in which no lines connect the points. Start by locating all the x-coordinates in order to determine the domain and range of a discrete graph. The graph's entire set of x-coordinates makes up the domain. The graph's entire range of y-coordinates is considered to be the range.

What does a discrete structure's domain mean?

        The domain is the collection of all possible inputs for a function. The codomain is the collection of all permitted outputs.

What is an example of discrete structures?

     Graphs, logical assertions, and combinations are a few examples of discrete structures. Infinite or finite discrete structures are both possible. Contrary to continuous mathematics, which works with structures whose values can span the real numbers or have other non-separable qualities, discrete mathematics deals with discrete objects.

The required value of the function is 2

In the case of a function from one set to the other, each element of X receives exactly one element of Y.

The function's codomain and domain are respectively referred to as the sets Y and X as a whole.When a function is defined, the domain and codomain are not always explicitly specified, and one may just be aware that the domain is a subset of a bigger set without having to conduct any (perhaps difficult) computation. In mathematical analysis, "a function from X to Y" typically refers to a function that may have a valid subset of X as its domain.

The given function is of the form :

g(x) = - x² - 7

Now let us find the required values.

g (-3) = - (-3)² - 7 = 2

g (-2) = - (-2)² - 7 = -3

g (1 ) = - ( -1 )² - 7 = -6

Hence the required value of the function is 2 at x = -3 .

A student ran the Turkey Trot 5K (5 kilometers) race on Thanksgiving Day. Using the ratio 1 mile : 1.61 kilometers, which set-up would correctly convert 5 kilometers to miles

Answers

The conversion of 5 kiiometers to miles is 3.11 miles

How to convert the distance from kilometers to miles

The given parameters are

Distance covered by the students = 5 kilometers

The ratio of the distance is given as

1 mile : 1.61 kilometers

Multiply both sides of the ratio by 5

So, we have the following ratio expression

5 * 1 mile : 1.61 kilometers * 5

Evaluate the product in the above expression

So, we have the following ratio expression

5 miles : 8.05 kilometers

Divide both sides of the ratio by 1.61

So, we have the following ratio expression

5/1.61 miles : 8.05/1.61 kilometers

Evaluate the quotient in the above expression

So, we have the following ratio expression

3.11 miles : 5 kilometers

Rewrite as

5 kilometers : 3.11 miles

This means that

5 kilometers = 3.11 miles

Substitute 5 kilometers = 3.11 miles  in Distance covered by the students = 5 kilometers

So, we have

Distance covered by the students = 3.11 miles

Hence, the distance covered by the students is 3.11 miles
