Answer:
45
Step-by-step explanation:
12 % of the marbles are blue, and
18 % of the marbles are green, so
30 % of the marbles are either blue or green.
There are 150 marbles.
30 % × 150 = 0.30 × 150 = 45
The number of blue or green marbles is 45.
-2x<5-3
-2x<2
divide both sides by -2
x<-1
remember +/-=-
that's why it's a negative answer
Answer:
10 to the power of 2

Answer:
54ab
Step-by-step explanation:
the only two factors of 54ab^2 and 54ab is 1 and 54ab and the greatest of that would be 54ab.
Finding the "probability that at least one is girl" can be done much easier by subtracting the "probability that none is girl" from 1, since these 2 events are the complement of each other, and either one or the other, but never both, may happen.
consider the tree diagram of the problem, check the picture, each branching represents a birth. The only branch where there is no girl (no g), is
bbbbbb with a probability of (1-0.534=0.466) per each letter b.
we know that the probability of a particular branch is the multiplication of the probabilities of each letter in the branch.
so in the case, P(bbbbbb)=

finally, P(at least 1 girl) = 1- P(no girl)=1-P(bbbbbb)=1-0.01=0.99
Answer: 0.99
