Answer:

24 cars are green

Step-by-step explanation:

We know

Amir notices that 3 out of every 50 cars that pass by his window are green.

So, the ratio is 3:47

To get from 50 to 400, we time 8.

If he observes 400 cars, what is the best estimate of how many will be green?

We take

3 x 8 = 24 cars are green

So, there will be 24 cars that are green.

The graph of g(x) = (x - 2)^3 + 7 is a transformation of the parent function f(x) = x^3.

The parent function f(x) = x^3 has a shape that is symmetrical about the origin and increases as x moves away from the origin. The graph of g(x) = (x - 2)^3 + 7 is also symmetrical about the origin, but it has been translated 2 units to the right and 7 units up from the parent function.

So, the graph of g(x) = (x - 2)^3 + 7 is similar in shape to the parent function f(x) = x^3, but it is shifted to the right and up on the coordinate plane.

There are 55 ways to form a train consisting of tank cars, boxcars, and flatcars by using concept of combinations.

If there are t tank cars, b boxcars, and f flatcars in the train yard, then the number of ways to form a train by selecting some of these cars is the same as the number of ways to distribute n = t + b + f identical objects into three distinct boxes, such that each box may receive any number of objects (including zero). The solution is given by the combination formula:

C(n + k - 1, k - 1)

where k is the number of boxes (in this case, k = 3). Therefore, the number of ways to form a train from t tank cars, b boxcars, and f flatcars is:

C(t + b + f + 3 - 1, 3 - 1) = C(t + b + f + 2, 2) = (t + b + f + 2)! / ((t + b + f)! * 2!)

There are 4 tank cars, 3 boxcars, and 2 flatcars in the train yard, then the number of ways to form a train is:

C(4 + 3 + 2 + 2, 2) = C(11, 2) = 55

Therefore, there are 55 ways to form a train consisting of tank cars, boxcars, and flatcars

Answer:

FG = 18

Explanation:

There is a simpler solution:

It has to do with the interior angle bisector theorem. (the illustration with the angle marks and the line show that it is being bisected)

Which will divide the opposite side into segments whose lengths have the same ratio as the adjacent sides of the bisected angle.

x / 24 = x + 10 / 54 →

54x = 24(x + 10) →

54x = 24x + 240 →

30x = 240 →

x = 8.

Since the expression x + 10 represents the length of FG, it's length must be 18.

The appropriate methods are

y = x + 8 and y = 4x + 2 - Substitution method

2x + 6y = 18 and x + 5y = 13 - Elimination method  

y = 3x + 3 and y = x + 7  - Substitution method

4x + 7y = 10 and -3x + y = -1 - Elimination method  

In this approach, the equation in one variable is obtained by either adding or subtracting the equations. We can add the equation to delete a variable if its coefficients are the same and have the opposite sign from the other variables.

Similarly to this, we can subtract the equation to get the equation in one variable if the coefficients of one of the variables are the same and their signs are the same.

From the given options, the system of equations

2x + 6y = 18 and x + 5y = 13  

4x + 7y = 10 and -3x + y = -1    

Can be solved using the Elimination method  

The algebraic technique for resolving multiple linear equations at once is called the substitution method. As the name implies, this method involves substituting a variable's value from one equation into another. In this manner, a pair of linear equations are combined into a single, simple linear equation with just one variable.

From the given options, the system of equations

Part 1: If Mary doubles the area of her original square garden, the expression that represents the area of Mary's new garden is 2x^2.

Part 2: If the side length of Mary's original garden is 9 feet, the area of Mary's new garden is 162 square feet.

Part 1: If Mary doubles the area of her original square garden, the new area of her garden will be 2 times the area of her original garden.

If the area of her original garden is x^2, then the area of her new garden will be:

2(x^2) = 2x^2

So, the expression that represents the area of Mary's new garden is 2x^2.

Part 2: If the side length of Mary's original garden is 9 feet, then the area of her original garden is:

x^2 = (9 feet)^2 = 81 square feet

To find the area of Mary's new garden, we can substitute 81 for x^2 in the expression we found in Part 1:

2x^2 = 2(81 square feet) = 162 square feet

So, the area of Mary's new garden is 162 square feet.

y= 2200 (3/4)x

Step-by-step explanation:

You can model a real-world situation involving an initial value and a constant growth or decay factor with an exponential equation in the form y=a(b)x, where b>0 and b≠1.

The constant a represents the initial value. It is the y-value of the equation when x=0.

The constant b represents the growth or decay factor.

When the equation models exponential growth, b>1.

When the equation models exponential decay, 0<b<1.

An exponential equation in the form y=a(b)x can model the value of the machine, y, x years after purchase. To write the equation, first look for phrases in the problem that tell you about the initial value, a, and the growth or decay factor, b.

Tessa is opening Tessa's Terrific Tees, her own custom T-shirt business. She bought a T-shirt printing machine that is currently valued at $2,200. The machine loses  1/4 of its value every year.

The constant a is the initial value. The initial value of the machine is $2,200. So, a=2,200.

The constant b is the decay factor, since the value of the machine is decreasing. The machine loses 1/4 of its value each year. In other words, the value of the machine each year will be 1–1/4= 3/4

times the value the year before. So, b= 3/4.

The exponential equation y= 2200 (3/4)x models the value of the machine.

An exponential equation in the form y=a(b)x that can model the value of the machine, y, x years after purchase is y= 2200*14*x

A linear equation is an equation that has the variable of the highest power of 1. The standard form of a linear equation is of the form Ax + B = 0. In mathematics, a linear equation is an equation that may be put in the form [tex]{\displaystyle a_{1}x_{1}+\ldots +a_{n}x_{n}+b=0, } where x_{1}, \ldots, x_{n} are the variables, and {\displaystyle b, a_{1}, \ldots, a_{n}}[/tex] are the coefficients, which are often real numbers.

Given that;

The cost of tshirt printing machine= $2200.

The lose of machine= 14

Now,

Substituting all the values in equation y=a(b)x

a=2200

b=14

y=2200*14*x

Therefore, the linear equation of the question will be y=2200*14*x

Answer: 4

Step-by-step explanation:

Answer:

The average rate of change of a function over an interval is a measure of how the function's value changes over that interval, given by the ratio of the change in the function's value to the change in the independent variable. To find the average rate of change of a function over an interval, we need to know the function's values at two points in the interval.

In the case of the function f(x) = x^2, the interval is -4 ≤ x ≤ 0. To find the average rate of change, we need to find the difference in the function's value between two points in this interval, and divide that by the difference in the x-values.

For example, if we compare the values of the function at x = -4 and x = 0, we have:

f(-4) = (-4)^2 = 16

f(0) = 0^2 = 0

The difference in the function's value is f(0) - f(-4) = 0 - 16 = -16.

The difference in the x-values is x2 - x1 = 0 - (-4) = 4.

So the average rate of change over this interval is the difference in the function's value divided by the difference in the x-values, or -16 / 4 = -4.

In other words, the average rate of change of the function f(x) = x^2 over the interval -4 ≤ x ≤ 0 is -4, meaning that for every 4 units of change in x, the function value decreases by 16 units.

The approximate surface area of the can is 180.55 sq.inches

A cylinder's surface area is the area that its surface takes up in three dimensions. A three-dimensional structure known as a cylinder has circular bases that are parallel to one another. There are no vertices on it. Area of three-dimensional shapes often refers to surface area. Square units are used to denote the surface area. Examples include cm2, m2, and so forth. A group of circular discs placed on top of one another might be thought of as a cylinder. The cylinder has both surface area and volume since it is a solid with a three-dimensional geometry.

The area of the cylinder is determined by adding the areas of its two circular bases and curving surface.

The Surface Area of Cylinder = Curved Surface + Area of Circular bases

The probability of obtaining the same number of heads is 3/8 or 0.375 when each of two persons tosses three fair coins.

The probability that two persons will obtain the same number of heads depends on the number of possible combinations of heads and tails that can be obtained by each person.

Since each coin flip results in either a heads or tails, there are 2 possible outcomes for each flip. Therefore, for three coin flips,

there are 2^3 or 8 possible combinations of heads and tails.

Out of these 8 combinations, there are 3 in which both persons have the same number of heads (i.e., 0 heads, 1 head, or 3 heads).

The function f(x) = 3x³ + 5 is neither even nor odd. To determine whether a function is even or odd, you need to check how the function behaves when x is replaced with -x.

To determine whether the given function is even, odd, or neither, we need to check the following conditions:

Even function: If f(-x) = f(x) for all x in the domain of f, then the function is even.

Odd function: If f(-x) = -f(x) for all x in the domain of f, then the function is odd.

Let's check these conditions for the given function:

f(x) = 3x³ + 5

f(-x) = 3(-x)³ + 5 = -3x³ + 5

f(x) = 3x³ + 5

Since f(-x) is not equal to f(x), the function is not even.

f(-x) = 3(-x)^3 + 5 = -3x^3 + 5

-f(x) = -(3x^3 + 5) = -3x^3 - 5

Since f(-x) is not equal to -f(x), the function is not odd.

Therefore, the given function is neither even nor odd.

Step-by-step explanation:

So first what you got to do is add and mulytplie

Answer:

x = 28

m∠A = 76°

m∠B = 104°

Step-by-step explanation:

Given the figure we can see that the two angles which measure

2x + 20 and 4x - 8 are adjacent linear angles and therefore they are supplementary angles which further means they add up to 180°

So

2x + 20 + 4x - 8 = 180

2x + 4x + 20 - 8 = 180\

6x + 12 = 180

6x = 180 - 12

6x = 168

x = 168/6

x = 28

We also have the property that angles that are vertically opposite each other at the vertex of the intersection of two lines are equal

So the angle represented by 2x + 20 = 2(28) + 20 = 56 + 20 = 76°

∠A is a vertically opposite angle to this angle and therefore the magnitude of ∠A denoted by m∠A = 76°

The angle represented by 4x - 8 = 4(28) - 8 = 112 - 8 = 104°

Since ∠B is a vertically opposite angle to this angle we have

m∠B = 104°

The correct answer to this statistical problem is (c) uncertain, because there are other variables at play and correlation does not equal causation.

In this scenario, we're looking at the sales of Ben and Jerry's ice cream before and after the advertisement was introduced. The sales increased by 30% for the following three months after the advertisement. So, does this mean that the advertisement was effective? The answer is not as straightforward as a simple "yes" or "no."

Option (c) acknowledges that there are other variables at play and that correlation does not equal causation.

This is the most accurate answer because it recognizes that while the increase in sales may be related to the advertisement, it's impossible to say for sure whether the advertisement was the cause of the increase in sales.
