The domain for f(x) is all real numbers. (Blank) than or equal to 3

greater

Step-by-step explanation:

The domain is the number that x can be

sqrt(x-3) must be greater than or equal to zero

x-3  must be greater than or equal to zero

x must be greater than or equal to  three

The other restriction is x+2 cannot equal zero

x cannot equal -2

The first restriction is more restrictive so that is the one we go with

24

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;
