The group of 250 students and teachers will sit in one section. Each row in the section contains 16 seats. How many rows will they need to use so that everyone has a seat?

Approximately 16 rows will be required so that everyone has a seat.

Step-by-step explanation:

We are given the following in the question:

Total number of students = 250

Number of seats in each row = 16

Total number of rows required for everyone to sit =

Thus, approximately 16 rows will be required so that everyone has a seat.

Some seats will be left unused in the last row.

Number of seats unused =

6 seats are left unused.

these sign is used to tell weather the number is greater or less than the number   <   or >     but this sign means its equal =

step-by-step explanation:

the question requires us to calculate the approximate 95% confidence interval for the mean number of ounces of ketchup per bottle in the sample given the following statistics;

sample mean = 24

standard deviation, σ = 0.4

sample size , n = 49

the confidence interval for a population mean is calculated using the formula;

sample mean ± z-score*(σ/sqrt(n))

the z-score associated with a 95% confidence interval, from the standard normal tables, is;

1.96

substituting these values into the formula;

24 ± 1.96*(0.4/7)

= 24 ± 0.112

from the alternatives given, choice d is closest to the above expression;
