Answer:

B) What is your height measured to the nearest inch?

Step-by-step explanation:

Statistical questions are questions which can have a variety of answers, explanations & justifications.

Fpr example, asking the weather report to people from four different countries in four different continents is a statistical questions as their answers can vary.

$\rule{150pt}{2pt}$

Now, in the above question, the questions are asked to 205 students from the same school & same grade.

A) Since the students belong to the same grade and the same school, there will be no difference in the timings of their second period class. So, this question is non-statistical question.

B) Height among students can vary even if they're of the same age or gender. Since this question can have various answers, it's a statistical question.

C) The word given is 'STATISTICAL' & it will always have eleven letters in it. It's a non-statistical question .

D) The students in the survey all belong to the same school. So, all of the answers will be the same & it'll be a non-statistical question.

$\rule{150pt}{2pt}$

So, the correct answer is → B) What is your height measured to the nearest inch?

$\rule{150pt}{2pt}$

Answer:

B) What is your height measured to the nearest inch?

Explanation:

A statistical question can be answered by collecting data from various people which varies.

Here Look For the Question's which may vary person to person.

A) Assuming 6th graders must have same period and time schedule.
B) Height in school of 6th graders can vary person to person.
C) There are total 11 letters and doesn't vary. it's exactly 11 letters.
D) The audience are from the same school.

Hi there,
This is the original inequality equation:
$\frac{x}{x+1} \ \textless \ \frac{x}{x-1}$
So, we first need to find the critical points of equality, and we can do that by switching the less than sign to an equal sign.
$\frac{x}{x+1} = \frac{x}{x-1}$
Now, we multiply both sides by x + 1:
$x= \frac{x^{2} +x}{x-1}$
Then, we multiply both sides by x - 1:
$x^{2} -x= x^{2} +x$
Next, we subtract x² from both sides:
$-x=x$
After that, we solve for x. We do this by adding -x to both sides and dividing by 2. Doing so gives us x = 0, which is our first critical point. We need to find a few more critical points by testing x = -1 and x = 1. Here is how we do that:
x = −1 (Makes left denominator equal to 0)x = 1 (Makes right denominator equal to 0)Check intervals in between critical points. (Test values in the intervals to see if they work.)x <−1 (Doesn't work in original inequality)−1 < x <0 (Works in original inequality)0 < x < 1 (Doesn't work in original inequality)x > 1 (Works in original inequality)
Therefore, the answer to your query is -1 < x < 0 or x > 1. Hope this helps and have a phenomenal day!

Are 22 42 60 a right triangle or not?

Lelechka [254]

Answer:First things first, let's explain what a right triangle is. The definition is very simple and might even seem obvious for those who already know it: a right-angled triangle is a triangle where one and only one of the angles is exactly 90°. The other two angles will clearly be smaller than the right angle because the sum of all angles in a triangle is always 180°.

In a right angled triangle the sides are defined in a special way. The side opposing the right angle is always the biggest in the triangle and receives the name of "hypotenuse". The other two sides are called catheti. The relationship between the hypotenuse and each of the cathetus is a very simple one, as we will see when we will talk about Pythagoras' theorem.

Hypotenuse calculator

If all you want to calculate is the hypotenuse of a right triangle, this page and its right triangle calculator will work just fine. However, we would also recommend to use the specific tool we have developed at Omni Calculators: the hypotenuse calculator. The hypotenuse is opposite the right angle and can be solved by using the Pythagorean theorem. In a right triangle with cathetus a and b and with hypotenuse c, Pythagoras' theorem states that: a² + b² = c².

To solve for c, take the square root of both sides to get c = √(b²+a²). This extension of the Pythagorean theorem can be considered as a "hypotenuse formula". A Pythagorean theorem calculator is also an excellent tool for calculating the hypotenuse.

Let's now solve a practical example of what it would take to calculate the hypotenuse of a right triangle without using any calculators available at Omni:

Obtain the values of a and b,

Square a and b,

Sum up both values: a² + b²,

Take the square root of the result,

The square root will yield a positive and negative result. Since we are dealing with length, disregard the negative result,

The resulting value is the value of the hypotenuse c.

Now let's see what the process would be using one of Omni's calculator, for example, the right triangle calculator on this web page:

Insert the value of a and b into the calculator

Obtain the value of c immediately

As a bonus, you will get the value of the area for such a triangle.

Step-by-step explanation:Hope this helped u also may i have brainlist plz?

Solve the equation. Check for extraneous solutions. 9|9 – 8x| = 2x + 3

Bad White [126]

The answers of this equation are 39/37 and 6/5. To get the answers, the equation of the problem becomes 9(9-8x)=2x+3 and 9(8x-9)=2x+3. Then next step is to simplify first equation 1,
81=74x+3.
After, equation 2 is simplified
70x=3+81

Use the Distributive Property to simplify the expression. 2w+4+13w+1=

coldgirl [10]

Answer:

15w+5

How I did it:

add 2 and 13 and put the "w" after the answer which is 15. Then add 4 and 1. That is 5 so then it is 15w+5.
