Choose the situations that state an appropriate domain for the function a function predicts the number of online devices in terms of the number of people in the household. An appropriate domain for the function is whole numbers.

a self-serve ice cream shop sells ice cream by the ounce. the function C(w) represents the cost, in dollars, of w ounces of ice cream. An appropriate domain for the function is positive rational numbers

the function h(t) = -16t^2 represents the height, h(t), of an object from the ground at t seconds from being dropped. An appropriate domain for the function is all real numbers

an online company allows you to play games for $0.99 each after you pay a $10.00 membership fee. an appropriate domain for this function is all whole numbers greater than 0.

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;

answer:   35 % is the probability of a late departure or an early arrival.

step-by-step explanation:

let l represents the late departure and e represents the early departure.

then, according to the question,

p(l) = 12 %,   p(e) = 27 % and = 4 %

and, we have to find out,

but, we know that,

which is the required equation that will use to find the probability of a late departure or an early departure.

therefore,   the probability of a late departure or an early arrival =   35 %
