Answer:

180 miles

Step-by-step explanation:

This is a distance-rate-time problem. We need to use the equation: d = rt, where d is the distance, r is the rate, and t is the time.

Here, r = 60 mph and t = 3 hours. Plug these in to find d:

d = rt

d = 60 * 3 = 180 miles

Hope this helps!

The key word is "miles per hour."

We are given that the Johnson family can drive 60 miles in one hour.

So, we can multiply to find how far they will travel in 3 hours;

60 * 3 = 180 miles in 3 hours

Best of Luck!

Answer:

0.967 = 96.7% probability the rock sample actually contains raritanium

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: Positive reading

Event B: Contains raritanium

Probability of a positive reading:

98% of 13%(positive when there is raritanium).

0.5% of 100-13 = 87%(false positive, positive when there is no raritanium). So

P(A) = 0.98*0.13 + 0.005*0.87 = 0.13175

Positive when there is raritanium:

98% of 13%

P(A) = 0.98*0.13 = 0.1274

What is the probability the rock sample actually contains raritanium?

P(B|A) = \frac{P(A \cap B)}{P(A)} = \frac{0.1274}{0.13175} = 0.967

0.967 = 96.7% probability the rock sample actually contains raritanium
