Answer:
Step-by-step explanation:
You need to find the area of each of the shapes by multiplying the length by the width. Then, you need to add them all together. I won't do it for you because it will make it harder to learn stuff in the future but I told you the formula!!
Answer:
What is a polynomial?
- In mathematics, a polynomial is an expression consisting of indeterminates and coefficients, that involves only the operations of addition, subtraction, multiplication, and non-negative integer exponentiation of variables
What is a rational function?
- In mathematics, a rational function is any function that can be defined by a rational fraction, which is an algebraic fraction such that both the numerator and the denominator are polynomials.
Are all polynomials rational functions?
.A function that cannot be written in the form of a polynomial, so no they are not all functions.
Maybe write it down, like how you see other math problems.
And then solve it!

Answer: Null hypothesis : 
Alternative hypothesis : 
Step-by-step explanation:
Let 
be the proportion of women using supplements and 
be the proportion of women who did not to have died during that period .
Then the set of hypothesis for testing if the proportion of women elderly women who use dietary supplements is different than those who do not will be :-
Null hypothesis : [∵ it takes equality sign]
Alternative hypothesis : [∵ it takes ≠ sign to show difference]
Solution: We are given:
μ=180,σ=25,n=100
Therefore the standard error of the mean is
