Step-by-step explanation:

Since the unit rate is 2/1 or 2, than I'd divide 38 by 2 to get 19. Very simple.

Given:

Compound for an experiment = 4.25 ounces

Compound costs = $2.32 per ounce.

Teacher pays = $10

To find:

The amount of change teacher receive.

Solution:

Cost of 1 ounce of compound = $2.32

Cost of 4.25 ounce of compound = 4.25 × $2.32

                                                        = $9.86

It is given that, the teacher pays with a $10 bill.

Amount of change = $10 - $9.86

                                 = $0.14

Therefore, the teacher receive $0.14 change.

The experimental probability of drawing the cards, 2, 3, or 4, from the deck of 52 cards, with the frequency obtained from 200 draws is about 15.5%

An experimental probability is the probability of a specified event taking place, based on repeated trials or sampling.

The number of draws Rayna drew from the standard deck of cards = 200 draws

The frequency of the cards drawn, obtained from the frequency table are;

Frequency of 2 = 8

Frequency of 3 = 12

Frequency of 4 = 11

The experimental probability of drawing a card that has a value of 2 or a card that has a value of 3 or a card that has a value of 4 is therefore;

P(2, 3, 4) = (Frequency of 2 + Frequency of 3 + Frequency of 4)/The total number of draws Rayna drew

P(2, 3, 4) = (8 + 12 + 11)/200 = 0.155 = 15.5%

0.65  is the probability that the chosen student eats neither fish nor eggs.

What are examples and probability?

A number between 0 and 1 is the probability of an event, where, broadly speaking, 0 denotes the event's impossibility and 1 denotes its certainty.                  

                                      The likelihood of an event occurring increases as its probability increases. The flip of a fair (impartial) coin serves as a straightforward illustration.

We know that there is sample of 275 MHS Students

What is the domain and range?

The domain and range are fundamental concepts in mathematics that are used to describe the input and output values of a function or relation.

The domain of a function refers to the set of all possible input values, or x-values, for which the function is defined.

The range of a function refers to the set of all possible output values, or y-values.

To find the domain and range of functions and represent them in different formats.

To find the domain and range of a function:

The domain refers to the set of all possible input values (x-values) for the function.

The range refers to the set of all possible output values (y-values) for the function.

To represent the function as a table, you would list the input-output pairs. For example:

Input (x) | Output (y)

-3         |        -4

-1          |         2

0         |         0

Answer:

x=7

Step-by-step explanation:

First distribute the left side:

2(5+2x)= -4+6x

10+4x= -4+6x

Move like terms to one side

4x-6x=-10-4

Notice how the sign changes when we move it to the other side

-2x=-14

x=7

Answer:

Step-by-step explanation:

The type of function that fits the given description is D. Exponential decay.

In an arithmetic sequence, the difference between consecutive terms remains constant. If the y-values of a function form an arithmetic sequence that decreases in value, it means that the difference between consecutive terms is negative.
Exponential decay functions exhibit a constant ratio between consecutive terms, resulting in a decreasing sequence. As the x-values increase, the y-values decrease at a consistent rate. This is represented by the formula y = ab^x, where b is a constant between 0 and 1.
In contrast, linear functions have a constant difference between consecutive terms, resulting in an arithmetic sequence. However, since the y-values are decreasing, the function cannot be linear.
Exponential growth functions, on the other hand, have a constant ratio between consecutive terms, but they result in an increasing sequence. The y-values of an exponential growth function increase as the x-values increase.

Therefore, based on the given information, the most appropriate type of function is D. Exponential decay.

In a parallelogram,

 ⇒the angles adjacent to each other

    ⇒ are of the same measure

        ⇒so

             ∠A = ∠C

             ∠B = ∠D

Let's solve:

           \(7z +5 = 8z - 10\\5+10=8z-7z\\8z-7z=5+10\\z = 15\)

           \(5w-30=3w+10\\5w-3w=30+10\\2w = 40\\w=20\)

Let's check:

 ⇒ for all quadrilaterals like a parallelogram

    ⇒all the angle measures added up to 360, so:

     \((7z+5)+(8z-10)+(5w-30)+(3w+10)=360\\(7(15)+5)+(8(15)-10)+(5(20)-30)+(3(20)+10)=360\\(105+5)+(120-10)+(100-30)+(60+10)=360\\110+110+70+70=360\\220+140=360\\360=360\)

Thus:

  Answer: w = 20 and z = 15

Hope that helps!    

It should be noted that the opposite angles of a parallelogram are equivalent. Therefore, ∠A = ∠C and ∠B = ∠D.

Given:

Therefore, we obtain the following equations;

⇒ 7z + 5 = 8z - 10   and   5w - 30 = 3w + 10

Let us simplify each equation one by one.

It is impossible to give an exact solution for where g(x) is less than zero in interval notation, without knowing the specific function of g(x).

To find where g(x)<0, we need to find the values of x for which the function is negative. This can be done by solving the inequality g(x)<0.

Once we have found the values of x that make the function negative, we can write the answer in interval notation. Interval notation is a way of writing a set of numbers that fall within a certain range.

It is written using parentheses or brackets to indicate the endpoints of the interval and a comma to separate the two endpoints. For example, the interval notation for all numbers between 1 and 5 would be (1, 5).

Without knowing the specific function g(x), it is not possible to provide an exact answer for where g(x)<0. However, once you have solved the inequality g(x)<0, you can write the answer in interval notation by using the values of x that make the function negative as the endpoints of the interval.

For example, if the values of x that make the function negative are between -2 and 3, the answer in interval notation would be (-2, 3).

Answer:

x = 18°, ∠A = 110°

Explanation:

As the lines are parallel, their sums of total interior angle is 180°

∠A + ∠B = 180°

5x +20° +9x-92° = 180°

14x -72° = 180°

14x = 180° + 72°

14x = 252°

x = 18°

Solve for angle A:

∠A = 5x +20°

∠A = 5(18) +20

∠A = 110°

Solution:

Note that:

Use the equation "∠A + ∠B = 180°" to solve for x and ∠A.

Now, find ∠A.

A store sold 120 units of good A for $4 each and they sold 340 units of good B for $5 each. The given value of sales was $ 2,180.

To find out the value of sales when a store sold 120 units of good A for $4 each and 340 units of good B for $5 each, we have to calculate the total cost of good A and good B sold respectively and add them together.

Value of sales = Total cost of good A + Total cost of good B Total cost of good A

= Number of units of good A sold x Cost of each unit of good A Total cost of good A

= 120 x $4Total cost of good

A = $480

Total cost of good B = Number of units of good B sold x Cost of each unit of good B Total cost of good

B = 340 x $5

Total cost of good B = $1,700

Therefore,Value of sales = Total cost of good A + Total cost of good B Value of sales = $480 + $1,700

Value of sales = $2,180

Therefore, the value of sales was $2,180.

What is a Linear equation in one variable?

A univariate linear equation is an equation of the form ax + b = 0, where a and b are two integers, x is a variable, and there is only one solution.

For example, 2x+3=8 is a linear equation in one variable.

The given equation is 5000 - 50x = 4800 - 30x.

solving for 'x',

                        5000 - 50x = 4800 - 30x

                        5000 - 4800 = 50x - 30x

                        200 = 20x

                        x = 200/20

                        x = 10

                                                                                           = 5000 - 500                                                                                                                                              

                                                                                           = 450 liters

The amount of water after 10 minutes in Pool B will be = 4800 - 30(10)

                                                                                           = 4800 - 300                                                                                                                                              

                                                                                           = 450 liters.

B. The equation y = 3x - 7 represents a linear relationship between two variables, x and y. As the equation has a slope of 3, it indicates that as the value of x increases by 1, the value of y increases by 3. Therefore, the data are correlated positively.

C. This is incorrect. As mentioned in B, the equation represents a linear relationship between two variables, x and y, which are positively correlated.

D. This is correct. Although the equation represents a linear relationship between x and y, it does not imply causation. It is possible that x causes y, y causes x, or some other variable or variables may be influencing both x and y.
