[tex] {x}^{2} - 25[/tex]

Step-by-step explanation:

[tex](x + 5)(x – 5) \\ \\ = {(x)}^{2} - {(5)}^{2} \\ \\ = {x}^{2} - 25[/tex]

Answer:

x²-25

Step-by-step explanation:

To do a sum like this, break up the first bracket and multiply by the second (terms from the first bracket is in bold in first few steps for clarity):

(x + 5)(x – 5)

x(x-5)+5(x-5)

x²-5x+5x-25

x²-25

Answer:

The polling organization can be 95% confident that the interval from 0.455 to 0.505 captures the proportion of all city voters who would vote for Jones.

Step-by-step explanation:

took the quiz

The polling organization can be 95% confident that the interval from 0.455 to 0.505 captures the proportion of all city voters who would vote for Jones.

A confidence interval is a set of values used to estimate an unknown population parameter with a high degree of certainty. It is calculated from a sample of data and takes into account the sample's variability.

The polling organisation is 95% confident that the range of 0.455 to 0.505 accurately represents the proportion of all city voters who would vote for Jones.

This means that if the researcher repeated the sampling process a number of times and created a confidence interval for each sample, 95% of those intervals would contain the true proportion of all city voters who would vote for Jones.

Thus, it does not imply that the true proportion is 95% likely to fall within the interval.

The parametric equations that models the path of the rider are:

This refers to the type of equation that makes use of a parameter to define dependent variables.

Hence, we can see that to model the path of the rider, the parametric equation that can be best used is to model the direction of the bicycle which is moving 5 miles east and then continues 8 miles north, and the fact that they started at rest 0 and the equations to make the model are:

The graph to the top right is a function.

This is a function because it a straight, connected line.

The First graph isn't a function because the lines are connected, and doesn't pass the horizontal test.

The Bottom left graph isn't a function because there are two lines and they intersect.

The Bottom right graph isn't a function because there are points but aren't connected.

Answer:

No, because grabbing the math book changed the odds of grabbing the notebook.

These are not independent events as you didn't replace the first book so that changed the probability that you would draw a notebook second , Option C is the answer.

Probability is the likeliness of an event to happen.

It is given that there are three math books, two science books, and five notebooks.

Total number of books = 3 + 2 + 5 = 10

The probability of drawing a mathbook is 3 / 10 = 0.3

and then if the mathbook is not replaced then the total outcomes for drawing a notebook changes.

Therefore they are not independent events and Option C is the answer.

Answer:

[tex]y=\dfrac{3}{4}x+15[/tex]

Step-by-step explanation:

Given that,

A line goes through the point (-8,9), and has a slope of 3/4.

We need to express in the form of Ax+B for this line.

We have, m = 3/4

So,

[tex]y=\dfrac{3}{4}x+B[/tex]

Put y = 9 and x = -8 in the above equation.

[tex]9=\dfrac{3}{4}(-8)+B\\\\9=-6+B\\\\9+6=B\\\\B=15[/tex]

So,

[tex]y=\dfrac{3}{4}x+15[/tex]

It is the required equation of the line.

Answer:

D

Step-by-step explanation:

For each triangle, you are given two sides and the included angle (the one between those 2 sides). That's side-angle-side, so it is S-A-S.

The SAS Rule for Similar Triangles says that for 2 triangles X and Y, if you have the SAS of one and the SAS of the other, then X and Y are similar (same shape and proportions) if

(a) the angle in X is congruent (same) as the angle in Y

(b) the ratio between the two given sides in X is the same as the ratio between the two given sides in Y

For this particular problem, the ratio PR/PQ = 18/21 = 6/7 if you simplify by dividing both top and bottom by 3.

So we are looking for another triangle where we have the same ratio. (Put the smaller number on top, in the fraction.)

Answer A:  12/15 simplifies to 4/5, wrong answer

Answer B:  9/12 simplifies to 3/4, wrong answer

Answer C:  6/10 simplifies to 3/5, wrong answer

Answer D: 15/17.5 looks harder, because there is a decimal in it. But we know 17.5 is just 17 and a half, so I would first multiply top and bottom by 2

We get 30/35. That looks a lot better. Now it is easier to see we can divide both top and bottom by 5.

We get 6/7! That is the correct answer, so D is the triangle similar to PQR.

Answer / Step-by-step explanation:

4 * (2 + 3) - 12

To get our final answer, we need to follow PEMDAS, which is :

Parenthesis

Exponent

Multiply

Divide

Addition

Subtraction

These mean that this is the order you will solve by what is in the question, let us start with the parenthesis.

(2 + 3) fits this description, therefore we add them together :

4 * 5 - 12

There are no more parenthesis and also no more exponents, so move onto multiplying.

4 * 5 - 12

20 - 12

x = 142°

Step-by-step explanation:

Since angle x and the 38° angle are supplementary angles, we know that the following is true...

x + 38° = 180°

x = 180° - 38°

x = 142°
