Your fine( I just need this for an answer
The proportion of students that got the recommended amount of sleep is 0.179.
<h3>What is a proportion?</h3>
A proportion can be defined as an expression which is typically used to represent (indicate) the equality of two (2) ratios. This ultimately implies that, proportions can be used to establish that two (2) ratios are equivalent and solve for all unknown quantities.
<h3>How to calculate proportion of students that got the recommended amount of sleep?</h3>
Since the total number of students in this class is 28, we would develop an expression to relate the number of students that sleep at least for 5 hours per night:
Proportion = 5/28
Proportion = 0.179.

Complete Question:
Students in a high school statistics class responded to a survey designed by their teacher. One of the survey questions was “How much sleep did you get last night?” Here is a dotplot of the data: Experts recommend that high school students sleep at least per night. What proportion of students in this class got the recommended amount of sleep? Amount of sleep (h) (Round your answer to three decimal places.)
Answer:
If the question is (2/3x) = -10,
x = -(1/15) = - 0.06667
The check is presented under the explanation below
If the correct question is (2/3)x = -10,
x = -15
The check is presented under the explanation below
Explanation:
If the question is rightly written as it is in the attached document,
(2/3x) = -10
We can cross multiply and obtain
2 = -10 × 3x
-30x = 2
x = -(2/30) = -(1/15) = - 0.06667
To check
(2/3x) = -10,
(2 ÷ 3x) = -10
2 ÷ 3(-1/15) = 2 ÷ (-1/5) = 2 ÷ (-0.2) = -10 (Correct!)
If the correct question is
(2/3)x = -10
Divide both sides by (2/3)
x = -10 ÷ (2/3)
x = -10 × (3/2)
x = -15
To check
(2/3)x = -10
If x = -15
(2/3) × (-15) = -10 (Correct!)

Microwaves are a form of "electromagnetic" radiation; that is, they are waves of electrical and magnetic energy moving together through space. Electromagnetic radiation spans a broad spectrum from very long radio waves to very short gamma rays.
