~~~~~~~~~~~~~~~~~~~~~~~

\(\mathrm{Expand\:}\left(x+4y\right)^3:\quad x^3+12x^2y+48xy^2+64y^3\)

Step-by-step explanation:

Confidence Level - "P" values  

99% 2.58

Confidence Interval - "P" values  

(0.4433 , 0.5444 )  

The slope-intercept form is written as:

y = mx + b

So, we need to rewrite the given equation in this form:

x - y = 10

x - y - x = 10 - x

-y = 10 - x

(-1) * (-y) = (-1) * (10 - x)

y = -10 + x

y = x - 10

Now, we can graph the equation. In order to do so, we can plot two points that satisfy this equation and join them with a line.

Notice that, for x = 0:

y = 0 - 10 = -10

For x = 10:

y = 10 - 10 = 0

Thus, the points (0, -10) and (10, 0) satisfy the equation:

Answer:

(5, -3)

Divide 300 by 4 to find out what '1 part' would count as:

300/4 = 75

Multiply this by 5

75 x 5 = 375

Add the two values together

375 + 300 = 675

Step-by-step explanation:

Number of boys=300

Ratio of boys to girls=4:5

let the number of girls=y

300/y=4/5

Cross multiply

300×5=4×y

1500=4y

Divide through both sides by 4

1500/4=4y/4

374=y

Number of girls is 375

Total number of students=Number of boys+Number of girls

Total number of students=300+375

Total number of students=375

Answer:

Each cm cube has a surface area of 6cm, and it makes 100 mm cubes that have a 6mm surface area each.

Correlation between x & y is 0.6125.

Correlation (x,y) = cor(x,y)/root v(x) X v(y)

=1225/root1600 x 2500

=1225/40x50

=0.6125

In probability theory and statistics, the cumulative distribution function of a real-valued random variable X, or simply the distribution function of X weighted by x, is the probability that X takes a value less than or equal to x.

The cumulative distribution function (CDF) of a random variable X is defined as FX(x)=P(X≤x) for all x∈R. Note that the subscript X indicates that this is the CDF of the random variable X. Also note that the CDF is defined for all x∈R. Let's look at an example.

The required expression will be 2/x+15 as the problem says "the sum of 2 divided by x and 15".

An expression, often known as a mathematical expression, is a finite collection of symbols that are well-formed in accordance with context-dependent principles. Mathematical expressions consist of at least two numbers or variables, at least one arithmetic operation, and a statement. It's possible to multiply, divide, add, or subtract with this mathematical operation. An expression in mathematics is made up of numbers, variables, and functions (such as addition, subtraction, multiplication or division etc.) You can think of expressions as being comparable to phrases. A phrase in language may contain an action on its own, but it does not constitute a complete sentence.

Here,

2 divided by x,

=2/x

sum of 2/x and 15,

2/x+15

The conclusion is "the sum of 2 divided by x and 15," hence the necessary equation will be "2/x+15."

Using the factor theorem and limits, it is found that the end behavior of g(x) is that it goes to negative infinity.

-------------------------------

The Factor Theorem states that a function with leading coefficient a and zeros \(x_1, x_2, ..., x_n\) is defined by:

\(g(x) = a(x - x_1)(x - x_2)...(x - x_n)\)

In the given table, \(f(x) = 0\) for \(x = -4, x = 12\), thus the zeros are: \(x_1 = -4, x_2 = 12\)

Then, the definition is:

\(g(x) = a(x - (-4))(x - 12)\)

\(g(x) = a(x + 4)(x - 12)\)

\(g(x) = a(x^2 - 8x - 48)\)

The end behavior is the limit of g(x) as x goes to infinity, thus:

\(\lim_{x \rightarrow \infty} g(x) = \lim_{x \rightarrow \infty} ax^2 = a \times \infty\)

Since the leading coefficient a is negative:

\(a \times \infty = -\infty\)

Thus, the end behavior of g(x) is that it goes to negative infinity.

It can be inferred that Broadway shows with higher ticket prices tend to be more popular and offer more performances.

Now,

Since,  More popular shows have higher ticket prices and offer more performances.

Hence, Based on the information given, the best explanation for the relationship between ticket prices and the number of performances is that more popular shows tend to have higher ticket prices and offer more performances.

This is supported by the strong, positive relationship indicated by the value of r being 0.763, which suggests that as ticket prices increase, the number of performances tends to increase as well.

Therefore, it can be inferred that Broadway shows with higher ticket prices tend to be more popular and offer more performances.

To ensure that the frame is a rectangle, the carpenter needs to make sure that opposite sides of the frame have the same length.

In other words, the two 6-foot-long boards must be opposite to each other and the two 8-foot-long boards must be opposite to each other.

This way, the carpenter can ensure that opposite sides of the frame are parallel and that the angles between these sides are right angles, which are characteristics of a rectangle.

Additionally, the carpenter could use a square or a measuring tape to check that the angles between the two sides of each length are 90 degrees. This will confirm that the frame is indeed a rectangle.

Answer:

a) y = 1.4x

b) 1.4, that is, any time x changes by 1, y changes by 1.4.

Step-by-step explanation:

A)

We want an equation in the following format:

y = mx

Point (5,7).

This means that when x = 5, y = 7. So

y = mx

7 = m*5

5m = 7

m = 7/5

m = 1.4

So the equation is:

y = 1.4x

B.) explain how to interpret M is the slope of the line.

The slope is how much y changes when x changes by 1.

In this case, it is 1.4, that is, any time x changes by 1, y changes by 1.4.

The coefficients on the x2 terms cancel each other because 1 – 1 = 0.

The constant was not included.

The coefficients on the x terms were subtracted incorrectly; 8x – 6x = 2x (not negative).

Answer:

Sample Response: If you simplify the first expression, you will not get the second expression. In the first expression, the x2 terms have coefficients of 1 and -1 and, when combined, the result is 0. Also, the x terms have coefficients of 8 and -6 and, when combined, the result is 2. Finally, the constant from the first expression is not in the second expression.
