Answer:
1.54 m
Step-by-step explanation:
Given information:
<u>Three groups of students</u>
- 20 students with a height of 1.67 m
- 16 students with a height of 1.50 m
- 14 students with a height of 1.40 m
⇒ Total number of students = 20 + 16 + 14 = 50
To find the <u>mean height</u> of all the students, <u>divide</u> the <u>sum of all the students' heights</u> by the <u>total number of students</u>:
Therefore, the mean height of all the students is 1.54 m
We have the following curve:<span>
To find the tangent lines to the curve
we need to use the concept of derivative, but we can’t solve this
problem for , thus, let's apply implicit differentiation, so:
Therefore the horizontal lines occurs when , then:
If we substitute this in the original
equation we have:
This is an absurd result because it is
impossible for a squared number to get a negative number. So the conclusion is that there is no any value of in
which the curve has horizontal tangent lines.</span>
