Hi there!

We have the numbers:
0 1 2 3 4 5 6 7
There are 8 total numbers, and 2 of those numbers (1 and 3) represent a success. Therefore:

Answer: x=−5 or x=5
Step-by-step explanation:
−3x4+27x2+1200=0
Step 1: Factor left side of equation.
−3(x2+16)(x+5)(x−5)=0
Step 2: Set factors equal to 0.
x2+16=0 or x+5=0 or x−5=0
x=−5 or x=5
This is what you do. You multiply 1/10 and 40. Like this: 1/10 x 40/1
Answer:
A
Step-by-step explanation:
Since there are 28 days in a regular February and 365 days in a total year, the probability that a random person is born in February is 28/365. This means that the probability that they were NOT born in February is 337/365, or answer choice A. Hope this helps!
