A group of friends wants to go to the amusement park. They have no more than $200 to spend on parking and admission. Parking is $11.50, and tickets cost $36.25 per person, including tax. Write and solve an inequality which can be used to determine xx, the number of people who can go to the amusement park.

the answer is a

step-by-step explanation:

$5.41

step-by-step explanation:

$20 - $14.51 = $5.49.

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;
