Which relation could be rewritten using function notation a) x=3 b) x+y=3 c) x+y^2=3 d) x^2 + y^2=3

For this case we have, by definition, a function is given in the form:

Where x is the independent variable and y is the dependent variable.

If we have:

We can rewrite it in the following way:

Comparing with the generic definition of a function, we have that

A relation that could be rewritten using function notation is option b.

answer: the answer is 30 miles per hour.

ft/s -> mphmph = ft/s 1.466667mph = 44 divided by 1.466667mph = 30.00000

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;
