if ABC forms a linear pair with CBD, use the Linear Pair Postulate to determine the value of x

Answers

There you go any questions?

The value of x from the figure is 13

The sum of angles on a straight line is 180 degrees.

From the given diagram;

2x + 13x - 15  = 180

Simplify

15x - 15  = 180

Add 15 to both sides

15x - 15 + 15 = 180 + 15

15x = 195

x = 195/15

x = 13

Hence the value of x from the figure is 13

A square poster has an area measure of 324x^2 + 540x + 225 square units. Determine the side length of the poster.

Answers

[tex]\huge\text{$(18x+15)$ units}[/tex]

Given the area, we need to find the side length. Let's start with the area equation for a square, where [tex]s[/tex] is the side length and [tex]A[/tex] is the area.

[tex]s^2=A[/tex]

Substitute in the known value.

[tex]s^2=324x^2+540x+225[/tex]

Now we need to factor the trinomial. The trinomial given for the area is a perfect square trinomial since [tex]324[/tex] ([tex]18^2[/tex]) and [tex]225[/tex] ([tex]15^2[/tex]) are both perfect squares.

We also know that [tex]a^2+2ab+b^2=(a+b)^2[/tex], which we can use to factor.

[tex]s^2=324x^2+540x+225\\s^2=(18x)^2+2(18x)(15)+15^2\\s^2=(18x+15)^2[/tex]

Now, take the square root of both sides to fully isolate [tex]s[/tex].

[tex]\sqrt{s^2}=\sqrt{(18x+15)^2}[/tex]

Keep in mind that the square root of any value squared is the original value.

[tex]s=\boxed{18x+15}[/tex]

Answer:

  rules of signs apply

Step-by-step explanation:

The point-slope form of the equation for a line of slope m through point (h, k) is ...

  y -k = m(x -h)

If the point coordinates are positive, their values show up in the equation with a minus sign.

Example:

  slope 2, point (3, 4)

  y -4 = 2(x -3)

__

If a point coordinate is negative, its value shows up in the equation with a plus sign.

Example:

  slope 2, point (-3, 4)

  y -4 = 2(x -(-3)) . . . . fill in the given value

  y -4 = 2(x +3) . . . . . simplify according to sign rules

Natalie buys a basketball for $25.57 and an air pump for $15.61. How much change will she receive if she pays for both items with a $50 bill?

Answers

Answer:

[tex]Change = \$8.82[/tex]

Step-by-step explanation:

Given

[tex]Basketball = \$25.57[/tex]

[tex]Air\ Pump = \$15.61[/tex]

[tex]Amount = \$50[/tex]

Required

Determine the change received

First, we need to calculate the total amount spent

[tex]Total = \$25.57 + \$15.61[/tex]

[tex]Total = \$41.18[/tex]

This implies that Natalie pays a total of $41.18

Next, we calculate the change as thus:

[tex]Change = Amount - Total[/tex]

[tex]Change = \$50 - \$41.18[/tex]

[tex]Change = \$8.82[/tex]

Hence, the change is $8.82

Jonathan, a college business student wants to study how many pages of notes fellow classmates took during a semester for a finance class. Past data reveals that pages of notes for a finance college class has a mean of 95 , with standard deviation 25 pages. He plans to take a random sample of 30 such college students and will calculate the mean pages of notes they take to compare to the known pages of notes students take for a finance college class. For these values, the mean and standard deviation of the sampling distribution of sample means for a sample of size 30 are: μx¯=95 and σx¯=2530√=4.6. What is the probability that the sample mean for a sample of size 30 will be at least 99? You may use a calculator or the portion of the z-table given below.

Answers

Using the normal distribution and the central limit theorem, it is found that there is a 0.1913 = 19.13% probability that the sample mean for a sample of size 30 will be at least 99.

Normal Probability Distribution

In a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

It measures how many standard deviations the measure is from the mean. After finding the z-score, we look at the z-score table and find the p-value associated with this z-score, which is the percentile of X.By the Central Limit Theorem, the sampling distribution of sample means of size n has standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].

For the population, the mean and the standard deviation are given by, respectively, [tex]\mu = 95[/tex] and [tex]\sigma = 25[/tex].

For a sample of 30, we have that:

[tex]n = 30, s = \frac{25}{\sqrt{30}} = 4.6[/tex]

The probability that the sample mean for a sample of size 30 will be at least 99 is one subtracted by the p-value of Z when X = 99, hence:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

By the Central Limit Theorem

[tex]Z = \frac{X - \mu}{s}[/tex]

[tex]Z = \frac{99 - 95}{4.6}[/tex]

[tex]Z = 0.87[/tex]

[tex]Z = 0.87[/tex] has a p-value of 0.8078.

1 - 0.8087 = 0.1913.

0.1913 = 19.13% probability that the sample mean for a sample of size 30 will be at least 99.
