1) In 2000, magazine A had 5,000 subscribers more than magazine B. 2) The available options indicate that the subscription numbers for both magazines are dropping. 3) As the years progress from 2000, the subscriber counts for both magazines approach zero.
Response:
The average depth is 12.75 cm.
The depth variance is calculated as 13.02 cm².
Clarification:
Uniform probability occurs when every outcome is equally probable.
In this scenario, we have a lower limit of the distribution denoted as a and an upper limit referred to as b.
The mean of the uniform distribution is:
The variance of the uniform distribution is represented as:
Uniform distribution across the interval (6.5, 19)
Thus, we have: 
So
Mean:
Average depth is 12.75cm.
Variance:
The variance of depth equals 13.02 cm².
To determine the time interval δt, we must subtract the starting time from the ending time. In this scenario, the first value in the coordinates signifies time:
δt=50 - 0
δt= 50s
The time interval is 50s.

<span>If the gratuity changes directly with the number of guests, which formula outlines the connection between the gratuity, t, and the number of guests, g?
t = 1.8g t = g/18 g = 1.8t g = t/18
</span>
18/10 = 1.8
36/20 = 1.8
54/30 = 1.8
