Answer:
reflection is defined as the change in the direction of a wavefront at the interface between two different media, bouncing the wavefront back into the original medium. A common example of reflection is reflected light from a mirror or a still pool of water, but reflection affects other types of waves beside light.

Using a calculator, the line of best fit for the function is given by:
y = 51.7x - 5.7.
<h3>How to find the equation of linear regression using a calculator?</h3>
To find the equation, we need to insert the points (x,y) in the calculator. For this problem, a linear regression is used because the data only increases.
From the given table, the points are:
(1, 68), (2,97), (3, 134), (4, 176), (5, 241), (6,335).
Inserting these points on the calculator, the line of best fit for the function is given by:
y = 51.7x - 5.7.

Interpreting (1,15) with (4,60), found that (4,60) is 4 times of the coordinate (1,15).
<h3>What are coordinates?</h3>
A pair of numbers that describe the position of a point on a coordinate plane by using the horizontal and vertical distances from the two reference axes.
For interpreting we have to find the relation between (1,15) and (4,60)
We have, (1,15)
For x- coordinate 1, y- coordinate will be 15
Now,
let us take x- coordinate=2 then y- coordinate =30
again, if x-coordinate = 3 then y-coordinate = 45
lastly, if the x-coordinate =4 then y-coordinate = 60
That means (4,60) is the 4 times of the coordinate (1,15) i.e., the x-coordinate is 4 times as well as the y- coordinate is 4 times.

Two angles are said to be linear if they are adjacent angles formed by two intersecting lines. The measure of a straight angle is 180 degrees, so a linear pair of angles must add up to 180 degrees.
Answer:
0.384
Step-by-step explanation:
pet supplier has a stock of parakeets of which 20% are blue parakeets
20/100 = 0.2 blue parakeets (success)
1-0.2 = 0.8 not parakeets (not success)
A pet store orders 3 parakeets from this supplier
we need to find the chance of getting exactly one blue from 3 parakeets
n=3, r=1, p = 0.2 , q=0.8
0.384
