Answer:
option-A
Step-by-step explanation:
we are given
we can factor each terms
and then we can take common terms among them
we can replace it
and we get
now, we can take out common terms
we can see that common terms are 3 and b
we can simplify it
Answer:
Its A.
Step-by-step explanation:
6b^2 + 3b.
The GCF is 3b so we divide this into the expression giving the factors:-
3b(2b + 1) (answer).

Answer:
0.8% is a probability that a calculator chosen at random will be defective
Step-by-step explanation:
Probability of any event is given by:
where, A is any event.
As per the statement:
In a batch of 960 calculators, 8 were found to be defective.
here,
A = Defective calculator.
⇒Number of defective calculator = 8
and
Total number of outcomes = 960 calculators.
then by definition we have;
Simplify:
= 0.833333333 %
Therefore, a probability that a calculator chosen at random will be defective to the nearest tenth place is, 0.8 %

Tanya drives to work every day and passes two independently operated traffic lights. The probability that both lights are red is 0.55. The probability that the first light is red is 0.69. What is the probability that the second light is red, given that the first light is red?
0.83
0.75
0.80
0.73
Answer:
(C) 0.80
Step-by-step explanation:
Let the probability that the first light is red is= and
the probability that the second light is red= . Then,
Probability that both lights are red= = 0.55,
Probability that the first light is red= =0.69,
Probability that the second light is red, given that the first light is red==
=
=
≈
