According to the Central Limit Theorem the sum or average of at least 30 independent random variables with the same distribution is approximately normal. Therefore the answer is 'at least 30 measurements.'
Sophia’s work factoring a perfect square trinomial is 
Step-by-step explanation:
We have,
16
– 40x + 25
=
- 2(4x)(5) + 
Using the algebraic identity,

=
- 2(4x)(5) + 
≠ (
Thus, Sophia’s work factoring a perfect square trinomial is 
Ok ummm I honestly don’t know I’m so sorry I couldn’t help you wit this prob
Answer:
y = -3/2x + 2
Step-by-step explanation:
The equation has the format y = mx + b where m is the slope and b is the y-intercept.
The question gives you the y-intercept, so b = 2.
As for the slope, you need the fact that perpendicular lines have slopes that are opposite ("negative") reciprocals of each other.
The slope of the line given in the question is 2/3. The opposite reciprocal of 2/3 is - 3/2.
The equation for the line is y = -3/2x + 2
