<h2>Answer:</h2>

The example of a statistical question is:

Question 4: How old are the students in math class?

<h2>Step-by-step explanation:</h2>

<u>Statistical question--</u>

A statistical question is one which is based over the data which is sampled or collected such that there is a variability in the data.

Here the first three questions i.e.

Question 1 How old am I?

Question 2 How old is the teacher?

Question 3 How old will I be after my next birthday?

are not based over the sample these are based over a individual and not over the data or population. Hence, they are invalid.

The statistical question is:

D) Question: 4

Hey there, Damonealy!

The correct answer should be D since you are talking about multiple amount of data. As you can see, question number 1-3 are talking about the age of a single person but question D is talking about the ages of multiple students which can be used in a statistic.

Thank you for using Brainly.
See you soon!

150 decreased by 60%

Hello there the answer to your question would be 60. Since 150-(60%*150) = 150 - 60 *150 = (1-60%)*150 = (100%-60%) * 150= 40% * 150 = 40/100 * 150 = 40 * 150 ÷ 100 = 6000/100 = 60. Hope this helps you out, have a great day!

Triangle ABC is shown on the graph. What are the coordinates of the image of point B after the triangle is rotated 270° about th

irina [24]

The coordinates of the image of point B after the triangle is rotated 270° about the origin is (4, 2)

<h3>How to determine the image of point B?</h3>

The complete question is added as an attachment

From the attached image, we have the following coordinate

B = (-2, 4)

When the triangle is rotated by 270 degrees, the rule of rotation is:

(x, y) ⇒ (y, -x)

For point B, we have:

B' = (4, 2)

Hence, the coordinates of the image of point B after the triangle is rotated 270° about the origin is (4, 2)
