Which number does not round to 600?

1 answer:

4 0

A) We round the number up to the nearest hundred if the last two digits in the number are 50 or above.

B) We round the number down to the nearest hundred if the last two digits in the number are 49 or below.

C) If the last two digits are 00, then we do not have to do any rounding, because it is already to the hundred.

Answer:

k≥-1.5

Step-by-step explanation:

-(5k-3) ≤ 15 + 3k

-5k+3 ≤15 +3k

+5k +5k

3≤15+8k

-15 -15

-12 ≤ 8k

divide both sides by 8

-1.5 ≤ k

or k≥-1.5

An eyewitness observes a hit-and-run accident in New York City, where 95% of the cabs are yellow and 5% are blue. A police exper

Liula [17]

Answer:

0.1739 = 17.39% probability that the cab actually was blue

Step-by-step explanation:

Conditional Probability

We use the conditional probability formula to solve this question. It is

$P(B|A) = \frac{P(A \cap B)}{P(A)}$

In which

P(B|A) is the probability of event B happening, given that A happened.

$P(A \cap B)$ is the probability of both A and B happening.

P(A) is the probability of A happening.

In this question:

Event A: Witness asserts the cab is blue.

Event B: The cab is blue.

Probability of a witness assessing that a cab is blue.

20% of 95%(yellow cab, witness assesses it is blue).

80% of 5%(blue cab, witness assesses it is blue). So

$P(A) = 0.2*0.95 + 0.8*0.05 = 0.23$

Probability of being blue and the witness assessing that it is blue.

80% of 5%. So

$P(A \cap B) = 0.8*0.05 = 0.04$

What is the probability that the cab actually was blue?

$P(B|A) = \frac{P(A \cap B)}{P(A)} = \frac{0.04}{0.23} = 0.1739$

0.1739 = 17.39% probability that the cab actually was blue
