The answer is
D 18 3
I'm pretty sure
Answer:
9
Step-by-step explanation:
percentages are reversable. like instead of 18% of 50 you could reverse it and say what is 50% of 18. which is 9.
c. 4.6
21 X .22= 4.6
Calculating the variance requires finding the product of 21 and 22%. To make this easier we convert 22% into it's decimal form and construct the equation. To back check this answer we can use 10% of 21 voters which equals 2.1% then double that amount to reach 4.2%, knowing that we now have a close approximation of the variance we can eliminate answers a, b, and d, leaving c as the only logical choice.
Answer:
C
Step-by-step explanation:
the legs of a 30-60-90 triangle are 1 and
, while the hypotenuse is 2.
the ratio of the legs is therefore 1 :
→ C
Answer:
The zero product property states that if a⋅b=0 then either a or b equal zero. This basic property helps us solve equations like (x+2)(x-5)=0.
The Zero Product Property simply states that if ab=0 , then either a=0 or b=0 (or both). A product of factors is zero if and only if one or more of the factors is zero.
