Step-by-step explanation:
using the theorem of the bissector :

Answer:
0.3108 is the probability that the sample mean is between 7.8 and 8.2 minutes.
Step-by-step explanation:
We are given the following information in the question:
Mean, μ = 8 minutes
Standard Deviation, σ = 2.5 minutes
Sample size, n = 25
We are given that the distribution of time spent is a bell shaped distribution that is a normal distribution.
Formula:

Standard error due to sampling =

P(sample mean is between 7.8 and 8.2 minutes)

0.3108 is the probability that the sample mean is between 7.8 and 8.2 minutes.
Answer:
-1/3
Step-by-step explanation:
Step 1. Simplify setup.
12/x - 6 = 18/x - 4
Step 2.Subtract 12/x from both sides.
-6 = 6/x - 4
Step 3. Add 4 to both sides.
-2 = 6/x
Step 4. Divide it all by 6 to leave X alone.
-1/3 = x
So X equals to -1/3.
