Determine whether the underlined number describes a population parameter or a sample statistic. Explain your reasoning. Sixty-fi
Levart [38]

Answer: A. The number is a sample statistic because it is a numerical description of all of the passengers that survived.

Step-by-step explanation:

A population is simply similar items or events that a researcher or an experimenter is interested and wants to carry out an experiment on.

A statistic is simply referred to as the piece of information gotten from the population while a sample statistic is the piece of statistical information which a researcher will be able to get from the statistic.

In this scenario, the number is a sample statistic because it is a numerical description of all of the passengers that survived.

What angle has the same sine value between 0-180? as Sin 24
Inessa05 [86]

Answer:

Sin156

Step-by-step explanation:

Given

Sin24

Required

Find equivalent between 0 to 180;

Let 24 be represented by \theta

So, \theta = 24

From Trigonometry ratios;

Sin\theta = Sin(180 - \theta) where 0\leq \theta \leq 180

Recall that \theta = 24

So, we have to substitute 24 for \theta in the above expression.

This gives

Sin24= Sin(180 - 24)

Subtract 24 from 180

Sin24= Sin156

Hence, the equivalent of Sin24 is Sin156
