On a standardized exam, the scores are normally distributed with a mean of 300 and a standard deviation of 40. Find the z-score of a person who scored 300 on the exam.

Answers

A z-score of 0 indicates that the person's score is equal to the mean, so they are right at the Average Performance level.the z-score of a person who scored 300 on the exam is 0.

The z-score of a person who scored 300 on the exam, we can use the formula:

z = (x - μ) / σ

where z is the z-score, x is the raw score, μ is the mean, and σ is the standard deviation.

In this case, the person scored 300 on the exam, which is equal to the mean (μ). Therefore, we can substitute these values into the formula:

z = (300 - 300) / 40

Simplifying the equation, we have:

z = 0 / 40

Since any number divided by zero is undefined, we can conclude that the z-score of a person who scored 300 on the exam is 0.

The z-score measures the number of standard deviations a data point is away from the mean. In this case, a z-score of 0 indicates that the person's score is equal to the mean, so they are right at the average performance level.

The mean of the data set is 82.77

How to calculate the mean of the data set?

If we want to find the mean, we would have to put it at the back of our minds that the mean is the same as the average. As such, we would have to take the sum of all the values that have been listed in the data set and divide by the total number of the data.

The first step is to arrange the data set orderly from smallest to largest;

70, 71,79, 82,88,85,87,91,92

We have nine values in the data set thus the mean is;

70+71+79+82+88+85+87+91+92/9= 745/9= 82.77

Ali, Basti and Cian stand at three points A, B and C respectively. Suppose that the measure of angle ABC is 50 degrees , the measure of angle BAC is 60 degrees and Ali is exactly 150 ft away from Basti. Find the distance between Basti and Cian.

Answers

To find the distance between Basti and Cian, we can use the law of sines in triangle ABC. The law of sines states that the ratio of the length of a side to the sine of the opposite angle is constant for all sides and their corresponding angles in a triangle.

Let's label the distance between Basti and Cian as "x". We know that the measure of angle ABC is 50 degrees and the measure of angle BAC is 60 degrees. We also know that Ali is exactly 150 ft away from Basti.

Using the law of sines, we can set up the following equation:

sin(50°) / 150 = sin(60°) / x

To solve for "x", we can rearrange the equation:

x = (150 * sin(60°)) / sin(50°)

Using a calculator, we can evaluate the expression:

x ≈ (150 * 0.866) / 0.766

x ≈ 168.4 ft

Therefore, the distance between Basti and Cian is approximately 168.4 ft.

1. Identify the axis of symmetry for y = -3(x+3)^2-2. a. x = -2 b. x = 3 c. x = 2 d. x = -3 2. Choose the correct axis of symmetry for x = -4(y -4)^2+6 a. y = -6 b. y = -4 c. y =6 d. y = 4

Answers

Answer:

The answer is :

Step-by-step explanation:

Axis of symmetry is the equation where it cuts the middle of the quadratic graph.

For quadratic equation in the form of (x+a)² + b, the axis of symmetry will be (x+a) = 0 which is x = -a :

Question 1,

$(x + 3) = 0$

$x = - 3$

Question 2,

$(y - 4 )= 0$

$y = 4$

Answer:

$\boxed{x=-3} \\ \boxed{y=4}$

Step-by-step explanation:

Axis of symmetry is a line that cuts the parabola in half touching the vertex.

Quadratic forms ⇒ y = ax² + bx + c or x = ay² + by + c

Axis of symmetry ⇒ x = $\frac{-b}{2a}$ or y = $\frac{-b}{2a}$

First problem:

y = -3(x+3)²-2

Write in quadratic form ⇒ y = ax² + bx + c

y = -3(x² + 6x + 9) - 2

y = -3x² -18x - 27 - 2

y = -3x² -18x - 29

a = -3, b = -18

Find axis of symmetry.

$x= \frac{-b}{2a}$

$x=\frac{--18}{2(-3)}$

$x=\frac{18}{-6}=-3$

Second problem:

x = -4(y -4)² +6

Write in quadratic form ⇒ x = ay² + by + c

x = -4(y² - 18y + 16) + 6

x = -4y² + 32y - 64 + 6

x = -4y² + 32y - 58

a = -4, b = 32

Find axis of symmetry.

$y= \frac{-b}{2a}$

$y=\frac{-32}{2(-4)}$

$y=\frac{-32}{-8}=4$

Only 10 family members can attend if they choose Option 1. What is the cost of airfare for Option 1?

The act of simplifying something such that it is simpler to carry out or understand, or the thing that is the product of this simplifying process: The group offers suggestions for streamlining business processes. This grossly oversimplifies what actually transpired. See.

We have been given that

For option 1

Airfare = $x

Hotel = $600

For option 2

Airfare = $0.75x

Hotel = $800

Only 10 family members can attend if they choose Option 1.

10x + $600 .........eq 1.

12 family members can attend the reunion if they choose Option 2.

12(0.75)x + $800

9x + $800 ........eq 2.

By using Eq (1) and Eq (2)

10x + $600 = 9x + $800

10x - 9x = $800 - $600

x = $200

Put the value of x in the eq (1)

Then we get 10x + $600

= 10 x 200 + $600

= 2000 + $600

= $2600

Hence , the cost of airfare for Option 1 is $2600.

José encontró un álbum de fotos del abuelo cuando tenía nueve años si el álbum tenía 108 páginas cuantas veces se habría es que se habría escrito la cifra nueve para enumerar todo el libro

Answers

The total number of times the digit "9" would have been written to number the entire photo album is 12 + 9 = 21 times.

To determine how many times the digit "9" would have been written to number all the pages of the photo album, we need to analyze the numbering pattern.

Since the album has 108 pages, we can observe that the numbers 1 to 9 are repeated 12 times (1-9, 10-19, 20-29, ..., 90-99) to cover the first 99 pages. Each repetition consists of ten numbers, and the digit "9" appears once in each repetition.

So, the digit "9" would have been written 12 times for the numbers 9, 19, 29, ..., 89 and 99.

However, we have an additional 9 pages to consider, which are 100, 101, 102, ..., 108. Each of these pages contains a single "9" in its numbering.

Therefore, the total number of times the digit "9" would have been written to number the entire photo album is 12 + 9 = 21 times.

A school gets a big donation and adds ten rooms. This reduces the average numbe of pupils per room by ten. After two months, a storm badly damages five rooms forcing the school to close them. This causes the average number of pupils per room to increase by four. The number of pupils at the school remains constant throughou this time. How many pupils are at the school? Justify your answer with working.

Answers

Answer:

600 pupils

Step-by-step explanation:

Let x represent the number of pupils at the school.

Let y represent the initial number of rooms in the school.

The average before the donation is:

1. x/y

The average after the donation is:

2. x/(y+10)

Set an equation between those two averages (the second line is 10 less than the first):

x/(y+10) + 10 = x/y

The average after the storm is:

x/(y+10-5)

3. x/(y+5)

Create another equation from the second line and third line:

x/(y+5) - 4 = x/(y+10)

We now have two equations and two variables

1. x/(y+10) + 10 = x/y

2. x/(y+5) - 4 = x/(y+10)

Solving them leads to x being 600 and y being 20.

Therefore there are 600 pupils at the school.

Which expression can be used to find the number of liters in 15 quarts?

Answers

The expression that can be used to find the number of liters in 15 quarts is 15 quarts/1 * 0.95 liters/1 quart

How to determine the expression?

The volume is given as:

Volume = 15 quarts

In standard unit of conversion, we have:

1 quart = 0.95 liters

So, the equation becomes

Volume = 15 quarts/1 * 0.95 liters/1 quart

Hence, the expression that can be used to find the number of liters in 15 quarts is 15 quarts/1 * 0.95 liters/1 quart

To solve for x and y, we can use substitution.

From the second equation, we have y = 2 - x.

Substituting this into the first equation, we get:

Sax + b(2 - x) = 0

Expanding this equation, we get:

Sax + 2b - bx = 0

Rearranging the terms, we get:

x(Sa - b) = 2b

Dividing both sides by (Sa - b), we get:

x = 2b/(Sa - b)

Substituting this value of x into the second equation, we get:

2b/(Sa - b) + y = 2

Substituting y = 2 - x, we get:

2b/(Sa - b) + (2 - 2b/(Sa - b)) = 2

Simplifying this equation, we get:

4b/(Sa - b) = 2

Multiplying both sides by (Sa - b)/2, we get:

2b = (Sa - b)

Simplifying this equation, we get:

b = a/2

Substituting this value of b into the equation for x, we get:

x = 2b/(Sa - b) = 2(a/2)/(Sa - a/2) = a/(2S - 1)

Substituting these values of x and y into the given point (x, y) = (a + b), we get:

(a/(2S - 1), 2 - a/(2S - 1)) = (a + a/2, a/2)

Therefore, the solution is:

x = a/(2S - 1) and y = 2 - a/(2S - 1).

The length of arc is calculated using:

So, we have:

5π = 100/360 * 2πr
