Answer:
Statistical sampling is drawing a set of observations randomly from a population distribution. ... By repeating the sampling operation a large number of times, perhaps 1000, we decrease the sampling error and increase the quality of the estimates.
Answer: las option.
Step-by-step explanation:
The equation of the line in slope-intercept form is:

Where m is the slope of the line and b is the y-intercept.
Then function given in the problem has the form:

Where:
m=3
b=-2
Therefore, it is a linear function.
By definition, the domain of the linear functions that are not bounded, is all the Real numbers.
Therefore, the answer is:
<em> {x | x is a real number}</em>
7x^4 - 21x^2a^2 + x^2a^2 - 3a^4
7x^4 - 20x^2a^2 -3a^4
Step-by-step explanation:
Given
x = 3 , y = 4
<h3>xy - 2x</h3>
= 3 * 4 - 2 * 3
= 12 - 6
= 6
Hope it will help :)
Answer:
Solution given:
we have
f(x)=x²-9x-36
let
y=x²-9x-36
when
x=0
y=-36
when
y=0
0=x²-9x-36
x²-12x+3x-36=0
x(x-12)+3(x-12)=0
(x-12)(x+3)=0
either
x=12
x=-3
So,
x and y intercepts are (-3,0)(12,0) and 0,-36)
