The right answer is Option B.
Step-by-step explanation:
Given,
Length of movie = 106 minutes
Time taken to get to theater = x minutes
Time taken to get back = x minutes
Total time = x+x = 2x minutes
Total time = 154 minutes
According to given statement;
Time taken to get to and get back + Length of movie = Total time
2x+106=154
154=2x+106
The equation 154=2x+106 describes the time it takes Ingrid to get to the movie theater.
The right answer is Option B.

Answer:
Option C
Step-by-step explanation:
The central Limit Theorem says the sampling distribution of the sample mean is approximately normal under certain conditions
The conditions are
i) the population should be symmetrial. If population is skewed sample size should be sufficiently large atleast 30
ii) Samples should be drawn strictly at random
iii) the sample observations should be independent
Thus we find that option a is not necessary because even for skewed large sample size allows the theorem
Option b is not correct since if population is less than 30, sampling itself is not necessary.
Option d is also wrong since normality is not necessary
Only option C) The sample size must be large (e.g., at least 30) is the necessary condition
