trasher [3.6K]2 years ago
4 0

Answer:

C

Step-by-step explanation:

3 - \frac{x}{2} ≥ 12 ( subtract 3 from both sides )

- \frac{x}{2} ≥ 9 ( multiply both sides by 2 to clear the fraction )

- x ≥ 18

multiply both sides by - 1, reversing the symbol as a result of multiplying by a negative quantity

x ≤ - 18

Maria will take two books with her on a trip. Suppose that the probability that she will like book 1 is .6, the probabilitythats
morpeh [17]

Answer:

0.25 is the required probability.

Step-by-step explanation:

We are given the following in the question:

Probability that like book 1 = 0.6

P(1) = 0.6

Probability that like book 2 = 0.5

P(2) = 0.5

Probability that Maria likes both the books = 0.4

P(1\cap 2) = 0.4

We have to find the conditional probability that she will like book 2 given that she did not like book 1.

Thus, we have to evaluate:

P(2|1') = \dfrac{P(2\cap 1')}{P(1')} = \dfrac{P(2)-P(1\cap 2)}{1-P(1)}\\\\P(2|1') =\dfrac{0.5-0.4}{1-0.6} = 0.25

0.25 is the conditional probability that Maria will like book 2 given that she did not like book 1.

What is x?
xxMikexx [17]

Answer:

x = 24

Step-by-step explanation:

MO is the angle bisector of ∠LMN, thus the following ratios are equal.

\frac{MN}{ML} = \frac{NO}{OL}, that is

\frac{12}{x} = \frac{7}{14} ( cross- multiply )

7x = 12 × 14 = 168 ( divide both sides by 4 )

x = 24
