Which best represents the inequality?

Answer:

kl is a volume with sides that are equal

If the point K  is over -9 and L is over 15 then the value of KL is 24.

The length along a line or line segment between two points on the line or line segment.

Distance=√(x₂-x₁)²+(y₂-y₁)²

A number line is a horizontal line that has equally spread number increments.

On the number line K is over -9 and L is over 15

We need to find the distance of KL.

KL=OL-OK

Where the OL is 15 and OK is -9.

Now plug in these values in KL

KL=15-(-9)

When minus and minus are multiplied we get positive.

=15+9

Add fifteen and nine we get twenty four.

=24

Hence, if the point K  is over -9 and L is over 15 then the value of KL is 24.

Answer: 15y+50=x

Step-by-step explanation:

Answer:

a. Perry covered a larger area

b. Karina covered an area of 9 units squared

Perry covered an area of 18 units squared

Step-by-step explanation:

Here, we are to justify our answer using mathematical reasoning.

Firstly, we need to deduce who out of the two has covered the greatest area.

The best way to go about this is by looking at the dimensions of the shapes in which they have individually covered.

For Karina, we have a square of sides 3 units by 3 units

While for Perry, we have a rectangle of dimension 9 units by 2 units

We know that judging by the areas of both, a square of side 3 by 3 has a smaller area compared to a rectangle of side 9 by 2

So since the rectangle has the bigger area, then Perry has covered a larger area during her community service

We are told to calculate the areas;

For Karina , we have;

3 by 3 = 3 units * 3 units = 9 units squared

For Perry, we have

9 by 2 = 9 units * 2 units = 18 units squared

B) The graph models P(x) = 12x − 168.  

C) The x-axis represents the number of sales.  

D) The break-even point for the number of sales and profit is (14, 0)

Step-by-step explanation:

Answer:

B) The graph models P(x) = 12x − 168.

C) The x-axis represents the number of sales.

D) The break-even point for the number of sales and profit is (14, 0)

Step-by-step explanation:

The x-axis represents the number of sales.

The graph models P(x) = 12x − 168

The break-even point for the number of sales and profit is (14, 0)

The x-axis represents independent values, such as the number of sales.

Profit = 12(#sales) − cost of materials → P(x) = 12x − 168

0 = 12x − 168 → x = 14 → (14, 0) is the break-even point.

Complete Question

The 16th percentile in a Normal distribution is 25 and 2.5% of the values in the distribution are greater than 40.

Which of the following are the best estimates for the mean and standard deviation of the distribution?

(a) mean = 32.5; standard deviation = 2.5

(b) mean = 32.5; standard deviation = 5

(c) mean 32.5; standard deviation = 10

(d) mean = 30; standard deviation = 2.5

(e) mean = 30; standard deviations = 5

Answer:

(e) mean = 30; standard deviations = 5

Step-by-step explanation:

From the question, we are told that the 16th percentile in a Normal distribution is 25

Hence the standard deviation is calculated as √of the 16th percentile in a normal distribution

= √25

= 5

Hence, the standard deviation = 5

In other to obtain the mean, we used the formula of z score.

z score formula =(x-μ)/σ,

where x is the raw score

μ is the population mean

σ is the population standard deviation.

From the question

x = 40, σ = 5

We are told that 2.5 % of the values is greater than 40

This means The percentile for this values = 100 - 2.5 %

= 97.5%

The z-score for a 97.5th percentile = 1.96

Hence,

z = (x-μ)/σ

1.96 = (40 - μ) / 5

Cross Multiply

= 1.96 × 5 = 40 - μ

= 9.80 = 40 - μ

μ = 40 - 9.80

μ = 30.2

≈ 30

Hence, the Mean = 30

A normal distribution is symmetric about the mean.

Given

[tex]P_{16} = 25[/tex] ---- 16th percentile

First, we calculate the standard deviation as follows:

[tex]\sigma = \sqrt{P_{16}[/tex]

So, we have:

[tex]\sigma = \sqrt{25[/tex]

[tex]\sigma = 5[/tex]

Next, we have:

[tex]2.5\%[/tex] of the value are greater than 40

This means that:

[tex]x =40[/tex] and 97.5% are less.

So: the z-score of 97.5% is:

[tex]z = 1.960[/tex]

Using z formula:

[tex]z = \frac{x - \mu}{\sigma}[/tex]

Substitute values for z, x and [tex]\sigma[/tex]

So, we have:

[tex]1.960 = \frac{40 - \mu}{5}[/tex]

Multiply through by 5

[tex]5 \times 1.960 = 40 - \mu[/tex]

[tex]9.8 = 40 - \mu[/tex]

Collect like terms

[tex]\mu = 40 - 9.8[/tex]

[tex]\mu = 30.2[/tex]

Approximate

[tex]\mu = 30[/tex]

Hence, the mean is 30 and the standard deviation is 5

Answer:

( − ∞ , ∞ ) hope i help

Step-by-step explanation:

First, solve each inequality. I'll solve the first one first.

7 ≥ 2 x − 5

12 ≥ 2 x

6 ≥ x

Therefore, x could be any number less than or equal to 6. In interval notation, this looks like:

( − ∞ , 6 ]

The parenthesis means that the lower end is not a solution, but every number above it is. (In this case, the lower end is infinity, so a parenthesis must be used, since infinity is not a real number and so it cannot be a solution.) The bracket means that the upper end is a solution. In this case, it indicates that not only could  

x

be any number less than 6, but it could also be 6.

Let's try the second example:

3 x − 2 4 > 4

3 x − 2 > 16    3 x > 18 x > 6

Therefore, x could be any number greater than 6, but x couldn't be 6, since that would make the two sides of the inequality equal. In interval notation, this looks like:

( 6 , ∞ )  

The parentheses mean that neither end of this range is included in the solution set. In this case, it indicates that neither 6 nor infinity are solutions, but every number in between 6 and infinity is a solution (that is, every real number greater than 6 is a solution).

Now, the problem used the word "OR", meaning that either of these equations could be true. That means that either  x  is on the interval  ( − ∞ , 6 ] or the interval  ( 6 , ∞ )

. In other words,  x

is either less than or equal to 6, or it is greater than 6. When you combine these two statements, it becomes clear that  

x

could be any real number, since no matter what number  

x

is, it will fall in one of these intervals. The interval "all real numbers" is written like this:

( − ∞ , ∞ )

Answer:

Please see attached image

Step-by-step explanation:

Recall that for a reflection of the triangle, we proceed to reflect its vertices across the given line. A reflection places the image of the three vertices at exactly the same number of units on the other side of the line as the original vertex was.

Please see attached image for description.

We go from vertex A straight perpendicular towards the line, and count two divisions to reach the line, so we move in the exact same down direction two divisions on the other side of the given line and mark its image (point A').

We do similarly with point B (six divisions to reach the given line, and continue also 6 divisions to the other side to create its image B'.

Finally vertex C is 5 divisions from the given line, and we continue 5 divisions on the other side of the line to place its image.

Once this is done, we simply join the image points with segments to form the triangle.

Alt. Ext. Angles Theorem.

m∠1 = 150

Step-by-step explanation:

∠1 and ∠8 are alternate exterior angles formed when the transversal line cuts across the 2 parallel lines. According to the alternate exterior angles theorem, both are congruent. Therefore,

m∠1 = m∠8

m∠1 = (50x)°

m∠8 = 150

Set both equal and solve for x

50x = 150

Divide both sides by 50

50x/50 = 150/50

x = 3

Unknown angle:

m∠1 = (50x) = 50*3 = 150°

Answer:

Rozalie spent 7 hours at the parking garage.

Step-by-step explanation:

The equation for the above Question can be given as:

$7.5 + 2.75x

Where x = hourly rate

We are told that Rozalie spent $26.75

The number of hours Rosalie spent at the parking garage is calculated as:

$7.5 + 2.75x = $26.75

2.75x = $26.75 - $7.5

2.75x = 19.25

x = 19.25/2.75

x = 7 hours

Therefore the number of hours Rozalie spent at the parking garage was 7 hours.
