Answer:
GPA stands for grade point average. the highest you can get is 4.5. There is no such things as a 95 GPA. To calculate, take the number or point per grade you have, A is 4.0, B is 3.0, C is 2.0, and so on, and add them all up and then divide by the number of classes you are taking.
Step-by-step explanation:
Probability is all about multiplying fractions.
The first fraction is the probability of picking a girl.. so how many of the 12 total children are girls. (8/12)
The second fraction is the probability of picking a boy.. so how many of the 11 remaining children are boys. (4/11)
8/12 X 4/11 = 8/33 -> this isn't even an option but I'm like 10000% this is the right answer..
I started off this answer feeling so confident lol. good luck.
Answer:
F and B (as far as I can see).
Step-by-step explanation:
First, let's simplify the equation. You can easily do this by dividing by -4.
-4x < 20
/-4 /-4
x > -5
REMEMBER- Whenever dividing or multiplying a negative number with inequalities, the sign flips!!
On A, we can see that it has a negative symbol, but if we were to divide that, the sign would flip, making -5 greater than x. That's not what we want.
On B, the 20 is negative instead of the 4. Does this change anything?
4x > -20
/4 /4
x > -5
Nope! It still simplifies to what we had at the beginning so it works!
C and D are slightly confusing me because, well, I don't really see how it's relevant to anything so... It doesn't even have a inequality symbol so I don't know lol.
E is wrong because we need the 5 to be positive.
F is obviously right compared to our first answer.
X^4-3x^3-28x^2+36x+144=(x-6)(x^3+3x^2-10x-24)
x-6 is a factor
