5. The Central Limit Theorem allows for a researcher to: estimate the sampling distribution of a sample statistic, but only if the researcher takes many samples of the same
size from the same population.
estimate the sampling distribution of a sample statistic using the results from one sample taken from the
population of interest.
observe the true, population-level values of the quantity being estimated.
ensure that the study results are scientifically useful.

x+14

step-by-step explanation:

225x²+4=0

225x²=0-4

225x²=-4

x²=-4/225

x=±√-4/225

this linear equation would have just one solution.

step-by-step explanation:

the reason why this would have one solution is that it is an expression with just one variable. since that variable is not raised to a power, it will always have just one solution.

the domain of a function is the set of input values, x , for which a function is defined. the domain is shown in the left oval in the picture below. the function provides an output value, f(x) , for each member of the domain.
