Askier is trying to decide whether or not to buy a season ski pass. a daily pass costs $64. a season ski pass costs $400. the skier would have to rent skis with either pass for $20 per day. how many days would the skier have to go skiing in order to make the season pass less expensive than the daily passes?

7 or more days

because 64x6=384 64x7=448

400 is less than 448 the ski rental is extra information in this problem becase it stays the same either way.

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;
