hope i helped
0.25 is a reduction
Scale factor < 1 is a reduction.
Scale factor > 1 is an enlargement.
Hope that helps!
Answer:
- How many students attend the college each year?
- What is the professor-to-student ratio at the college each year?
- What percentage of applicants each year are accepted to the college?
Step-by-step explanation:
Statistical questions are questions that can be answered by collecting data that vary. The questions, "in what college is the state located?", "in what year was the college founded?", and "how many buildings are owned by the college" can collect data, however, the data does not vary.
Let's consider two prime numbers where each is larger than 2
Say the primes 7 and 11. Adding them gets us 7+11 = 18. This counter example disproves the initial claim since 18 = 9*2 = 6*3 making 18 composite (not prime)
In general, if we let p and q be two primes such that q > p > 2 and q is the next prime after p, then p and q are both odd. If any of them were even then they wouldn't be prime (2 would be a factor)
Adding any two odd numbers together leads to an even number
Proof:
p = 2k+1 where k is some integer
q = 2m+1 where m is some integer
p+q = 2k+1+2m+1 = 2(k+m) + 2 = 2(k+m+1) which is in the form of an even number
That proof above shows us that adding any prime larger than 2 to its next prime up leads to an even number. This further shows us that the claim is false overall. It is only true if you restrict yourself to the primes 2 and 3, which add to 5. Otherwise, the claim is false.
I would go with A because if u use the distributive property u get something very similar
