Answer:
The correct answer is
b. random sampling error
Step-by-step explanation:
Sampling is a statistical method of selecting a predefined number of observations from a larger population to determine the characteristics of and to represent the larger population.
A sampling error is a type of error in statistics that is as a result of a difference between the calculated statistical values of a selected sample and that of the entire population. A sample of a population with an error does not properly represent the statistics of the population.
By the definition of sampling in statistics, sampling error can be eliminated by Increasing the size of the sample taken from the larger population, analogous central limit theorem.
Answer:
0
Step-by-step explanation:
Here,
p=2
b=2
c=?
we know that,
c= p²-b²
=4-4
=0
Answer:
The speed of the ball in terms of i and j is (15.76 i, 6.37 j)
Step-by-step explanation:
Given;
velocity of the ball, v = 17 mph
angle of inclination, θ = 22⁰
The horizontal component of the velocity is calculated as;

The vertical component of the velocity is calculated as;

Therefore, the speed of the ball in terms of i and j is (15.76 i, 6.37 j)
<em>The x and y intercept of 5x + 5y = -30 are (-6, 0) and (0, -6) respectively.</em>
<h2 /><h2>
Explanation:</h2>
The Standard Form of the equation of a line is given by:

So:

is written in Standard Form. The x and y intercepts are:

So:
FOR X-INTERCEPT:

FOR Y-INTERCEPT:

Finally,<em> the x and y intercept of 5x + 5y = -30 are (-6, 0) and (0, -6) respectively.</em>
