Answer:
The correct answer is the last on that’s states: it is not a valid sample because it is not a random sample of the population.
Step-by-step explanation:
When a researcher wants to know about the same thing, he/she has to take a sample from the population.
Example, consider a researcher wants to know how many hours the students study at home in a week, so the researcher has to take the sample from the student population.
Here, he/she gives the advertisement and offers $10 for 10 people. Therefore for anyone can come they might not required for a particular study.
Therefore, the answer is the last one.
The volume of the rectangular chocolate bar is 130 cm³.
<h3 /><h3>How to find the volume of rectangular prism?</h3>
volume of the rectangular chocolate prism = lwh
where
- l = length
- w = width
- h = height
Therefore,
l = 0.65 m = 65 cm
h = 2 cm
w = 1 cm
Hence,
volume = 65 × 2 × 1
volume of the chocolate bar = 130 cm³

Answer:
Pythagorean Theorem: A² + B² = C²
You would use it to find a missing side or missing hypotenuse of a right triangle by pluggin in all of the known values of the triangle into the equation and then solving it.
Step-by-step explanation:
C² is the hypotenuse of the triangle (the longest side, and the side that is opposite the right angle).
A² and B² are the remaining two sides.
At rest
mg=836 N
as g=9.8
m=836/9.8=85.30 kg
when going up,
mg+ma=935N
ma=935-836= 99N
a=99/85.30 = 1.16 m/s².
that is the acceleration of elevator
