Answer: 30

Step-by-step explanation: In this problem, we are asked to evaluate the following expression if w = 6.

Since we know that w = 6, we can evaluate 5w by substituting 6 in for w. In addition, it's important to understand that 5w means 5 times w.

So substituting 6 in for w, we have 5(6).

Notice that I used parentheses around the 6. It's always a good idea to use parentheses when substituting numbers in for variables.

So we have 5(6) which is 30.

Andrew [12]

What does perpendicular mean? Well, in elementary geometry it mean 2 lines that intersect at a right angle. (90°).

So for Part one. all you need to do is draw a straight line down from the point X. Name the end point of that line M.

Now you will connect the line M and Z.

Thats it! I hope this helped!! :)

The probability that a new car battery functions for more than 10,000 miles is .8, the probability that it functions for more th

MAXImum [283]

Answer:

There is a 50% probability that its total life will exceed 20,000 miles.

Step-by-step explanation:

To solve this question, we use the following formula:

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

In which P(A|B) is the probability of A happening, given that B has happened, $P(A \cap B)$ is the probability of A and B happening, and P(B) is the probability of B happening.

In this problem, we want:

The probability of the total life of the car battery exceeding 20,000 miles, given that it exceeded 10,000 miles.

$P(A \cap B)$ is the probability of exceeding 20,000 and 10,000 miles. It is the same as the probability of exceeding 20,000 miles(If it exceeded 20,000 miles, necessarily it will have exceeded 10,000 miles). So $P(A \cap B) = 0.4$

P(B) is the probability of exceeding 10,000 miles. So $P(B) = 0.8)$

$P(A|B) = \frac{P(A \cap B)}{P(B)} = \frac{0.4}{0.8} = 0.5$

There is a 50% probability that its total life will exceed 20,000 miles.
