Answer: <span>A. A function is a special type of relation for which there is a rule that pairs each input with exactly one output.
Option B is incorrect because it does not include that there cannot be two x-values with the same y-value. Option C is incorrect because it is a relation, not just a set of ordered pairs. Option D is incorrect because there <em>is</em> a particular pattern in a function.
Hope this helps!</span>
Answer:
370
Step-by-step explanation:
The venn diagram corresponds to students who were sick in January at a Chicago high school.
Students who had only fever= n(A) = 80
Students who had only headache= n(B) = 90
Students who had only cough = n(C) =60
Students who had both cough and fever = n(AC) = 10
n(AB) = 40:n(BC) = 30 n(ABC) = 20
Hence total students = 800
no of students who were absent due to other reasons = 100
REmaining students = 700
Students who were sick = sum of all =330
So no of students who were at school = 700-330 = 370
I think it is D intersecting
Answer:
D,
Step-by-step explanation:
D would be the only one that doesn't represent a function because the y-value never changes while the x-value does.
Answer:
Step-by-step explanation:
We have to write 243 as a power of some number.
So, if we factorize 243 we get,
243 = 3 × 3 × 3 × 3 × 3
Therefore, we can write 243 as a power of 3.
No other number can be written in powers of 243 because it do not contain any other factor than 3.
Hence, 243 can be written as :
