Answer:
See below
Step-by-step explanation:
25¹¹ - 5¹⁹
Convert to base 5 = (5²)¹¹ - 5¹⁹
= 5²² - 5¹⁹
Factor out the GCF = 5¹⁹(5³ - 1)
= 5¹⁹(125 - 1)
= 5¹⁹ × 124
= 5¹⁹ × 4 × 31
31 is a factor of 25¹¹ - 5¹⁹, so the expression is divisible by 31.

Answer:
Option C) 0.25
Step-by-step explanation:
We are given the following information in the question:
Mean, μ = 22 minutes
Standard Deviation, σ = 11.9 minutes
We are given that the distribution of response time is a bell shaped distribution that is a normal distribution.
Formula:
P(response times is over 30 minutes)
P(x > 30)
Calculation the value from standard normal z table, we have,
![P(x > 30) = 1 - 0.749= 0.251 = 25.1\%](https://tex.z-dn.net/?f=P%28x%20%3E%2030%29%20%3D%201%20-%200.749%3D%200.251%20%3D%2025.1%5C%25)
Thus, the correct answer is
Option C) 0.25
