Step-by-step explanation:
use the two point system to find equation of line segment, or you can just put one of the point from on equn of the lines (in options) to check whether it's satisfying the equation or not!
Answer:
c. 18.36-21.64
Step-by-step explanation:
Using the following formulas the lower and upper limits of the interval are calculated
Lower limit = mean - (standard deviation /√sample size)* Zr
Upper limit = mean + (standard deviation /√sample size)* Zr
Zr depends on confidence interval
Zr for 90% = 1.645
then
Lower limit = 20 - (4 /√16)* 1.645 = 18.355 ≈ 18.36
Upper limit = 20 + (4 /√16)* 1.645 = 21.645 ≈ 21.64
All the values that go into a function
The output values are called the range.
Domain → Function → Range
Example: when the function f(x) = x^2<span>is given the values x = {1,2,3,...} then {1,2,3,...} is the domain.
f(x)=y=x^2
y are range and x are domain</span>
