There are 87 skiers in line to ride the chair lift. If each chair seats 2 people, how many skiers will be on the last chair?

Step-by-step explanation:

Divide 87 by 2 to represent how many chairs will be occupied.

43 1/2 chairs will be occupied, meaning that 43 chairs have 2 people, and one chair has 1 person.

The chair with one person is represented as the last chair.

true

step-by-step explanation:

d. 24+-0.114

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;
