To obtain the sample, one can choose the names of 6 students out of a hat from the students in the class using random sampling.
<h3>What is random sampling?</h3>
It should be noted that a simple random sample is a subset of a statistical population where each member of the subset has an equal probability of being chosen.
Systematic sampling is when the sample members from a larger population are selected based on a fixed, periodic interval. If you want to select a random group of 6 students from a population of about 60 using systematic sampling, every 10th person on the list is selected.

Answer:
y - 7 = -2(x - 4)
Step-by-step explanation:
We are asked to write the equation of a line in point slope form
Step 1 : find slope
We are given the slope to be -2
Slope m = -2
Step 2: substitute m into point slope form
y - y_1 = m( x - x_1)
y - y_1 = -2 ( x - x _1)
Step 3: substitute the point into the equation
y - y_1 = -2( x - x _1)
( 4 , 7)
x_1 = 4
y_1 = 7
y - 7 = -2( x - 4)
We don't need to open the bracket because we are asked to write the equation in a point slope form
For this equation you would use Pythagorean's theorem. Which is super helpful in finding missing sides of triangle. so a^2 + b^2 = c^2. The only tricky part is having to remember that C IS ALWAYS THE LONG SIDE OF THE TRIANGLE. Always and forever! The equation you would use to figure this out would be:
29^2 + b^2 = 51^2
And the solve for b.
I hope this helped! :)

The abscissa is the x-coordinate of the ordered pair and the ordinate is the y-coordinate. The ordered pair is therefore given to be,
(abscissa, ordinate)
or (x , y)
From the given, it is stated that the ordinate is three more than twice the abscissa. The ordered pair can therefore be written as,
(x, 2x + 3)
If x = -1 then,
y = 2(-1) + 3 = 1
Ordered pair : (-1, 1)
If x = 0
y = 2(0) + 3 = 3
Ordered pair : (0, 3)
Hence, the answer to this is either the first choice or the second choice which appears to be just the same.
