<span>C. No, because although the results differ among the four surveys, the sample method used for all was the same. Luc RANDOMLY selects 40 students in every survey. Random selection in surveys do not create bias and the results are highly credible. This is because there are no preconceived notions or factors that affect the responses of people being surveyed.</span>
Answer:
x=27
Step-by-step explanation:
180-2x-40+180-3x+180-x-50+180-4x = 360
360-2x-40-3x+360-x-50-4x= 360
360-10x-90= 0
10x= 270
x= 27
<span>In the figure, all the dimensions of the cuboid
a = 4/5m side of the base
b = 1/3m second side of the base
c = h = 1/4m height solid
The volume is the product of the edge
V = abc = 4/5m * 1/3m * 1/4m = 4/60m</span>³ = 1/15m³
Answer B
<h3>
Determining the solution.</h3>
The solution(s) for the provided graph are (0, 6) and (6, 0)
<h3>What is a solution of a graph?</h3>
The solution of the <u>system of equations</u> is the <u>intersection</u> of the two equations.
<h3>Reasoning.</h3>
In the image provided, we can see two solutions (i<u>ntersection points)</u> that are intersected by a line and a circle.
<u>Those two solutions are:</u>
