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?

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.

(a)The domain of the function is, $\rm x \geq -c^2 \ x\neq0$

(b)The given function is discontinuous at x=0.

<h3>What is the domain and range of a function?</h3>

Domain is the set of values for which the given function is defined. Range is the set of all values which the given function can output.

The standard function is;

$\rm f(x)= \frac{\sqrt{x+c^2-c} }{x} , c > 0$

The domain of the given function is found as;

$\rm x+c^2 \geq 0 \ x\neq 0 \\\\ x\geq-c^2 \ x\neq 0$

The domain of the function is,

$\rm x \geq -c^2 \ x\neq0$

To find the function is continuous or not, we have to find the continuity;

$\rm f(x) = \frac{\sqrt{ x+c^2-c}}{x} ,c > 0$

At x= 0 the function is undefined. So that the function is discontinuous at x=0.

Hence, The domain of the function is, $\rm x \geq -c^2 \ x\neq0$ and the function is discontinuous at x=0.

Altitudes $\overline{ax}$ and $\overline{by}$ of acute triangle $abc$ intersect at $h$. if $\angle ahb = 132^\circ$, then what i

Answer: 48 degrees

-------------------------------------------------------

See the attached image for a visual of the problem and answer.

Based on the diagram, we have angle AHB = 132 degrees (given) equal in measure to angle XHY since these two angles are vertical angles.

Angles HYC and HXC are right angles due to the nature of AX and BY being altitudes. Recall that altitudes are segments that go from one vertex to the opposite side and they are perpendicular to the opposite side.

Focus on quadrilateral HXCY. So far, we know that...
Angle XHY = 132 degrees
Angle HYC = 90 degrees
Angle HXC = 90 degrees

The angle we want to find is angle ACB, which is the same as angle YCX. This angle is the missing angle of the quadrilateral HXCY.

For any quadrilateral, the four angles must add to 360 degrees.

(angle XHY) + (angle HYC) + (angle HXC) + (angle YCX) = 360
(132) + (90) + (90) + (angle YCX) = 360
312 + (angle YCX) = 360
312 + (angle YCX) - 312 = 360 - 312
angle YCX = 48 degrees

Since angle ACB is the same as angle YCX, we can say
angle ACB = angle YCX = 48 degrees

So in summary,
angle ACB = 48 degrees
