Which graph represents a proportional relationship?
I need the answer please
Answers
Answer:
The first one
Step-by-step explanation:
On a graph, if the line starts at the origin, where the 0 is, which is the center in this case, it is proportional
On a table, if the numbers all the have the same rate of change, which is y/x, then it is proportional

Select all of the descriptions which describe a transformation of the graph of f(x)=x that could result in
the graph of g(x) = 2x.
A. The graph is translated 2 units to the right.
B. The graph is rotated about (0,0), becoming steeper.
C. The graph is vertically stretched.
D. The graph is translated 2 units up.
E. The graph is vertically shrunk.
F. The graph is reflected across the x-axis.
Answers
Answer:
The descriptions that apply are E and F.
Step-by-step explanation:
Let's graph both functions, attached the result:
A: No. The graph is not reflected across x-axis. For this to happen, there should be a negative sign: g(x) = -x, for example
B: No, the graph doesn't translate. The graph only translates if there is: g(x) = a(x-c)+b, where b defines the vertical translation, and c the horizontal one.
C: No. This would happen for g(x)=x/2, for example.
D: No. Check the explanation of B.
E: Yes. The graph rotates due to the factor of 10. This rotation only applies for straight lines.
F: Yes. It stretched.

To find the area of a rectangle, multiply the length and the width.
The length of a rectangle is (X - 6) and the width of the rectangle is (x - 10). What is the area of the rectangle?
Answers
Answer:
Step-by-step explanation:
area = length * width
area = (x - 6) (x - 10)
area = x (x - 10) - 6 (x - 10)
area = x^2 -10x -6x -10
area = x^2 -16x -10

1. Every ratio yx for related pairs of x and y is equivalent.
2. Every sum x + y is the same for related pairs of x and y.
3. Every x term is a multiple of the previous term.
4. Every difference x – y is the same for related pairs of x and y please help me
Answers
Answer:
The correct answer is:
1. Every ratio yx for related pairs of x and y is equivalent.
Step-by-step explanation:
Proportion is defined as the relationship between two quantities. When one quantity changes the other is also changes.
For two quantities y and x when we say that both are proportional then t can be written as:
y∝x
Removing the proportionality symbol introduces a constant which is the ratio of y and x.
[tex]\frac{y}{x} = k[/tex]
This ratio of y and x, i.e. k is equivalent for all related pairs of x and y.
Hence,
The correct answer is:
1. Every ratio yx for related pairs of x and y is equivalent.
At a certain restaurant, 35 percent of the customers order the daily special each day. Assume that each day the customers arrive randomly and order independently. Let the random variable X represent the number of orders placed until the first daily special is ordered. The distribution of X is geometric and has an expected value of approximately 2.86. Which of the following is the best interpretation of the expected value?
A. Each day, 3 customers will order the daily special.
B. Over many days, the average number of customers ordering the daily special is approximately 2.86.
C. Over many days, it takes about 2.86 orders, on average, to be placed until the first daily special is ordered.
D. For a random sample of the days, the average number of orders of the daily special will be 2.86.
E. Each day, the ratio of the number of orders of the daily special to the number of orders of other menu items is about 2.86 to 1.

Answer:
C. Over many days, it takes about 2.86 orders, on average, to be placed until the first daily special is ordered.
Step-by-step explanation:

Option C. Over many days, It takes about 2.86 orders, on average, to be placed until the first daily special is ordered.
What Is a Random Variable?A random variable is a variable whose value is unknown or a function that assigns values to each of an experiment's outcomes. Random variables are often designated by letters and can be classified as discrete, which are variables that have specific values, or continuous, which are variables that can have any values within a continuous range.
Given here: The distribution of X is geometric and has an expected value of approximately 2.86. And 35 percent of the customers order the daily special each day. Thus clearly the correct and precise interpretation of the statement is Over many days, It takes about 2.86 orders, on average, to be placed until the first daily special is ordered.
Hence, Option C is the correct answer.

Answers
Respuesta:
29.00
Explicación:
una naranja 3.00
un melón 12.00
una manzana 2.00 (porque una docena equivale 12 artículos; 24/12 es 2)
tres naranjas 3(3.00) = 9.00
un melón 12.00
cuatro manzanas 4(2.00) = 8.00

If a gun fires 88 rounds per minute, how many rounds would it fire in 45 minutes?
Answers
Answer:
3960
Step-by-step explanation:
1minute = 88rounds
45minutes = xrounds
1/45 = 88/x
45(88)= 3960
3960/1 = 3960
x = 3960
The gun fires 3960 rounds in 45 minutes.
What is the proportion?A mathematical assessment of two numbers is called a proportion. If two sets of provided numbers rise or fall in the same relation, then the ratios are said to be directly proportional to each other.
Let x rounds would it fire in 45 minutes
As per the situation, we can write the proportion would be as:
1 minute : 88 rounds = 45minutes : x rounds
⇒ 1/88 = 45/x
Apply the cross-multiplication, and we get
⇒ x = 45(88)
⇒ x = 3960
This means a gun fires 3960 rounds in 45 minutes.

Write an equation in slope-intercept form for the line with slope 7 and y-intercept -8.
Answers
Answer:
y = 7x - 8
Step-by-step explanation:
The equation of a line in slope-intercept form is: y = mx + b, where m is the slope and b is the y-intercept.
The problem already gives us both of these values:
m = 7
b = -8
All we have to do is plug them in:
y = mx + b
y = 7x + -8
y = 7x - 8
Thus, the answer is y = 7x - 8.

Find the equation of the line that has a slope of 2
and passes through the point (5, -8). Write the
equation in point-slope form.
Answers
Answer:
The equation in the point-slope form will be:
[tex]y-(-8) = 2 (x-5)[/tex]
Step-by-step explanation:
The point-slope form of an equation is written as:
[tex]y-y_1=m\left(x-x_1\right)[/tex]
where m is the slope, and (x₁, y₁) is a point on the line.
Now, we will substitute the values of m and (x1, y1) in the given equation. Here,
m=2
and
(x1, y1) = (5, -8)
x1 = 5
y1 = -8
[tex]y-y_1=m\left(x-x_1\right)[/tex]
[tex]y-(-8) = 2 (x-5)[/tex]
Therefore, the equation in the point-slope form will be:
[tex]y-(-8) = 2 (x-5)[/tex]

The dimensions of a rectangular prism are 24 ft x 20 ft x 15 ft. What is the surface area
Answers
Answer:
2280 ft^2
Step-by-step explanation:
A rectangular prism has 6 faces. Each pair of opposite faces is congruent.
surface area = 2LW + 2LH + 2WH
surface area = 2(24 ft)(20 ft) + 2(24 ft)(15 ft) + 2(20 ft)(15 ft)
surface area = 960 ft^2 + 720 ft^2 + 600 ft^2
surface area = 2280 ft^2
