2, a whole number is equal to 200%
1/4, a fraction, is equal to 25%
200% + 25% = 225%
Answer:
1 c 2 b 3 a thats the order from greatest volume to smallest volume is quantity or power of sound; degree of loudness. we can have a volume of a shape by multiplying length and width and depth
Step-by-step explanation:
Answer: A (#26)
Step-by-step explanation:
So... it has degree of 7, so based on the fundamental theorem of algebra....it can have at most 7 solutions
now.. you have <span>−4, −4i, 2i <--- there are two complex ones there
-4i or 0-4i and 2i or 0+2i
now.. bear in mind that, complex solutions never come all by their lonesome, they come with their sister, the conjugate
thus, that means 0-4i comes with 0+4i and 0+2i comes with 0-2i
that makes only 5 roots though
that simply means that, the -4 one, has a multiplicity of 3
as far as the B) and C) sections, check Descartes Rule of Signs
which surely you've covered already

We know that the probability of picking a nervous person is 0.2. This implies that the probability of picking someone who is not nervous is 0.8.
When we pick a sample of two people, we multiply the probabilities of each single person. So, the possible outcomes and their respective probabilities are:
- Both people not nervous:
- First person nervous, second person not nervous:
- First person not nervous, second person nervous:
- Both people nervous:
Out of these four scenarios, the last three correspond to the description "at least one of the two is nervous". So, we have to sum their probability:
Alternatively, and probably more easily, we could solve this problem by complementary probability: we know that if event has probability , then the negation of has probability .
So, the negation of "at least one person is nervous" is "none of the two is nervous". We know that the probability of "no nervous people" is 0.64 (see above), so the probability of its negation (at least one nervous) is
