Answer:
- 20 seconds
- 70, 30, 20
Step-by-step explanation:
1. From the first floor to the 4th floor is a distance of 3 floors. From the first floor to the 16th floor is a distance of 15 floors, a distance that is 5 times as far as the first trip. We expect the second trip to take 5 times as long, or ...
(4 s) × 5 = 20 s
___
2. The smallest and largest ratio number sum to 2+7=9. That sum exceeds twice the remaining ratio number by 9-2×3 = 3. Since this difference represents a difference of 30, each of the original numbers must be 30/3 = 10 times its corresponding ratio number.
The three numbers are 7×10 = 70, 3×10 = 30, and 2×10 = 20.
<em>Check</em>
(70 +20) -2×30 = 30 . . . true
I belive your answer is 3
Identify any outlier(s) in the data. {52, 61, 42, 46, 50, 51, 49, 44, 40, 66, 53, 67, 45, 64, 60, 69}

There are none
For there to be a outlier there would need to be a number that is either around 74 or 34
Answer:
Step-by-step explanation:
Using Bayes' theorem, we have:
is a conditional probability: the likelihood of event A occurring, given that B is true.
is also a conditional probability: the likelihood of event B occurring, given that A is true.
P(A) and P(B) are the marginal probabilities of observing A and B, independently of each other.
We solve thus:
=
=
=
=
= or %
Therefore, if an individual tests positive, it is more likely than not (1 - 33.2% = 66.8%) that they do not use the drug.
To determine the measure of angle C. You would solve the equation for X. X+47=180. X= 180-47. X= 133. The measure of angle C is 133 degrees.
