Do PEMDAS
Parenthesis, exponent multiply, divide, add, subtract
We can do the parenthesis first, (6x3)=18, then add one to get 19.
Answer:
=-23y
Step-by-step explanation:
(-3y3-5y-2)+(-7y2+5y+2)
=-3yX3-5y-2-7yX2+5y+2
=-3X3y-5y-7X2y+5y-2+2
=-3X3y-7X2y-2+2
=-9y-7X2y-2+2
=-9y-14y-2+2
=-23y-2+2
=-23y
I hope this helps!
Answer:
pq=su
Step-by-step explanation:
its the only one that makes sense
Answer:
0.6 = 60% probability that the bead is RED or GREEN.
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
In this question, we have that:
There are 9 + 8 + 3 = 20 beads.
Of those, 9 + 3 = 12 are red or green.
So, there is a 
probability that the bead is RED or GREEN.
Answer: sample space
Step-by-step explanation: In determining the probability of a certain event occurring or obtaining a particular outcome from a set of different possible outcomes, such as in the toss of coin(s), rolling of fair die(s), the sample space comes in very handy as it provides a simple breakdown and segmentation of all possible events or outcomes such that in Calculating the probability of occurrence of a certain event, the event(s) is/are located in the sample space and the ratio taken over the total number of events.
