The restriction of the given equation is 
, other than 0≤x≤2π.
What is restriction of equation?
Restriction of the equation is the value of domain where the value is limited.
Given,
taking

The word "associative" comes from "associate" or "group";the Associative Property is the rule that refers to grouping. For addition, the rule is "<span>a + (b + c) = (a + b) + c</span><span>"; in numbers, this means
</span>2 + (3 + 4) = (2 + 3) + 4. For multiplication, the rule is "<span>a(bc) = (ab)c</span>"; in numbers, this means2(3×4) = (2×3)4<span>. Any time they refer to the Associative Property, they want you to regroup things; any time a computation depends on things being regrouped, they want you to say that the computation uses the Associative Property.</span>
Answer: 25%
Step by step explanation:
1. Turn it into a fraction (5/20)
2. Turn the faction into a decimal by dividing the numerator (5) by the denominator (20). (5÷20=0.25)
3. Multiply the decimal (0.25) by 100, to convert it into a percentage. (0.25×100=25%)
(b) one-sample t-test for a population mean
ur welcome :D
