Please help me! I'm stuck and really confused, thank you so much!

Answers

Answer:

(a) [tex]5 * (2x - 1) = 10x - 5[/tex]

(b) [tex]6 * x = x + 2x + 3x[/tex]

(d) [tex]y(3x + 4z) = 3xy + 4yz[/tex]

(e) [tex]z(2xy - 3y + 4x) = 2xyz - 3yz + 4xz[/tex]

Step-by-step explanation:

Solving (a):

Given

[tex]10x - 5[/tex]

Required

Express as a product

Express 10x as 5 * 2x

[tex]10x - 5 = 5 * 2x - 5[/tex]

Apply distributive property

[tex]10x - 5 = 5(2x - 1)[/tex]

[tex]10x - 5 = 5 * (2x - 1)[/tex]

So:

[tex]5 * (2x - 1) = 10x - 5[/tex]

Solving (b):

Given

[tex]x + 2x + 3x[/tex]

Required

Express as a product

Express 2x and 3x as 2 * x and 3 * x, respectively

[tex]x + 2x + 3x = x + 2*x + 3*x[/tex]

Apply distributive property

[tex]x + 2x + 3x = x(1 + 2 + 3)[/tex]

[tex]x + 2x + 3x = x(6)[/tex]

[tex]x + 2x + 3x = 6*x[/tex]

So:

[tex]6 * x = x + 2x + 3x[/tex]

Solving (c):

Given

[tex]\frac{1}{2}(x - 6)[/tex]

Required

Express as a sum/difference

Apply distributive property

[tex]\frac{1}{2}(x - 6) = \frac{1}{2}x - \frac{1}{2}*6[/tex]

[tex]\frac{1}{2}(x - 6) = \frac{1}{2}x - \frac{6}{2}[/tex]

[tex]\frac{1}{2}(x - 6) = \frac{1}{2}x - 3[/tex]

Solving (d):

Given

[tex]y(3x + 4z)[/tex]

Required

Express as a sum/difference

Apply distributive property

[tex]y(3x + 4z) = 3x * y + 4z * y[/tex]

[tex]y(3x + 4z) = 3xy + 4yz[/tex]

Solving (e):

Given

[tex]2xyz - 3yz + 4xz[/tex]

Required

Express as a product

Factorize

[tex]2xyz - 3yz + 4xz = 2xy * z - 3y * z + 4x * z[/tex]

Apply distributive property

[tex]2xyz - 3yz + 4xz = z(2xy - 3y + 4x)[/tex]

So:

[tex]z(2xy - 3y + 4x) = 2xyz - 3yz + 4xz[/tex]

The table below shows the height and the hand span of five students.

Which pattern of association best describes the relationship between the height and the hand span?

A. no association

B. nonlinear association

C. positive linear association

D. negative linear association

Answers

Positive linear association because increase in two inches higher increase hand span by .5 inches

There is no association between the height and the hand span.

We can only establish an association when there is a consistent rate of increase or decrease between two variables. The increase or decrease is linear when they occur smoothly.

As we can see, we can not establish any particular relationship between the height and the hand span hence we conclude that there is no association between them.

Ron randomly pulls a pen out of a box that contains 1 red, 2 black, and 3 blue pens. He does
this 4 times, replacing the pen each time, but pulls out a blue pen only 1 time. Ron concludes
that the observed frequency of pulling a blue pen will eventually be closer to the expected
frequency based on the theoretical probability of pulling a blue pen. Which reasoning best
supports his conclusion?

Answers

Answer: A

Step-by-step explanation:

Ron's conclusion that the observed frequency will eventually be closer to the expected frequency is reasonable and supported by probability theory.

What is Probability?

It is a branch of mathematics that deals with the occurrence of a random event.

The law of large numbers states that as the sample size increases, the observed frequency of an event will converge to the expected frequency based on the theoretical probability of the event. In this case, the expected frequency of pulling a blue pen is 3/6 or 1/2, which is based on the theoretical probability of pulling a blue pen.

Although Ron pulled a blue pen only 1 time in 4 trials, it is important to note that he replaced the pen each time.

This means that each trial was independent of the others, and the probability of pulling a blue pen in each trial remained the same at 3/6 or 1/2.

As Ron continues to repeat the trials and increase the sample size, the observed frequency of pulling a blue pen will become closer and closer to the expected frequency of 1/2, as predicted by the law of large numbers.

Therefore, Ron's conclusion that the observed frequency will eventually be closer to the expected frequency is reasonable and supported by probability theory.

Answers

Answer:

X-intercepts: (2,0) and (4,0)

Vertex: (3,-1)

Step-by-step explanation:

1) First, let's find the x-intercepts. The x-intercepts are the points at which the graph intersects the x-axis. Look at the x-axis. The x-axis is crossed at two points, (2,0) and (4,0). Therefore, those are the x-intercepts.

2) Now, let's find the vertex. For parabolas, the vertex can either be the lowest point of the graph (the minimum) or the highest point on the graph (the maximum). So, seeing how the graph goes up until infinity, find the lowest point the graph hits. Reading the graph, it would be (3,-1).

What is a number line?

A number line refers to a straight line in mathematics that has numbers arranged at regular intervals or portions along its width. A number line is often shown horizontally and can be postponed in any direction.

The definition of simplicity is making something simpler to achieve or grasp while also making it a little less difficult.

The section from zero to one is divided into 12 equal parts. And point P lies in the second section. Then the location of the point P will be given as,

⇒ 2 / 12

⇒ 1 / 6

The two fractions that lie on point P on the number line will be 1/6 or 2/12. Then the correct option is A.
