Answer:
Average rate of change = 10
Explanation:
Average rate of change = 
a = 2
f(a) = f(2) = (-2)² + 3(2) + 1 = 4 + 6 + 1
f(a) = 11
b = 5
f(b) = f(5) = (-5)² + 3(5) + 1 = 25 + 15 + 1
f(b) = 41
Thus:
Average rate of change = 

Average rate of change = 10
Answer: 1/15
Explanation:
Since it's a class of 6, and there are 2 students who forgot their lunch. The probability of firs choosing a student who forget their lunch will be 2 out of 6 which is 2/6.
When the next student who forget their lunch is picked there'll be 5 students left which means the probability then will be 1 out of 5 which is 1/5.
Therefore, the if the teacher chooses 2 students, the probability that both of them forgot their lunch will be 1/3 multiplied by 1/5 which will be:
= 1/3 × 1/5
= 1/15
The answer is c because the numerical expression correction is 28
Answer:
Our genetic predispositions and our specific environments interact. Environments can trigger gene activity, and genetically influenced traits can evoke responses from others.
As a child's brain develops, neural connections grow more numerous and complex. Experiences then prompt a pruning process, in which unused connections weaken and heavily used ones strengthen. Early childhood is an important period for shaping the brain, but throughout our lives our brain modifies itself in response to our learning.
