12 total roses.
Probability of selecting a pink rose would be 3/12 or 1/4.
p(pink)=3/12=1/4
The complement of that would be 1-1/4=3/4.
P(NOT pink)=1-1/4=3/4
So theres a 3/4 chance that she WON'T randomly select a pink rose.

Answer:
D. 4 real roots and 0 complex roots
Step-by-step explanation:
If I assume that the function you are saying is
There should be up to "4 roots," there can't be more or less than 4 total solutions. First, we need to check how many sign changes are there in this function. There are 3 positive real roots. Now lets check for negative roots.
There are is only 1 negative real root. Since we basically have 4 real roots, and the max is 4. There should be 4 real roots and 0 complex roots.
It's C because you need to find how many points each student earned per grade (freshman & sophomore). Then you multiply it by 30 to find out how many points each student scored in the whole class.
Hope this helps!
We have been given that on a coordinate plane a line with negative slope passes through points and . We are asked to find the rate of the change of the function.
We know that slope represents rate of change of function.
We will use slope formula to solve our given problem.
Let and .
Therefore, the rate of change of the given function is .
