Answer:
<em>The size of the sample 'n' = 2401</em>
Step-by-step explanation:
<u><em>Step:1</em></u>
Given that the margin of error = 2 % = 0.02
The margin of error is determined by

we know that the proportion

<u><em>Step:2</em></u>
<em>The margin of error is determined by </em>
<em> </em>
<em></em>

√n = 49
Squaring on both sides, we get
n = 49 × 49
n = 2401
<u>Final answer:-</u>
<em>The size of the sample 'n' = 2401 </em>
Answer:
Step-by-step explanation:
If the variation is proportional dividing the y-value by the x-value will give the same result for all table entries. That quotient is the constant of variation (k).
Here 6.4/4 = 11.2/7 = 16/10 = 20.8/13 = 1.6
The value of y varies directly as x, and the constant of variation is 1.6. The equation is ...
y = 1.6x
Answer:
C - He substituted incorrectly when calculating the constant of variation.
The image lines constructed are called parallel lines. They are parallel because they are all equidistant to each other at every point and at no point between any of the lines will there be an intersection of the three lines.
<h3>What does it mean for two or more lines to be equidistant from each other?</h3>
Equidistance is simply another word for equal in distance. That is, parallel lines maintain equal distance from each other at all points along them.
See the attached construction as well as more insights about parallel lines from the link below.
