Descriptive statistics are generally used for which of the following? check all that apply. to make general conclusions about populations using sample data to describe independent variables only to describe dependent variables only to simplify and summarize data

Correct answer is :

To simplify and summarize data

Step-by-step explanation:

Using sample data we can make inferences about a population using statistical methods such as linear regression. But descriptive statistics, as only describe general characteristics of a sample, can be not generalized to a larger population only by descriptive statistics.

Descriptive statistics (DS) can be used to describe dependent or dependent variables alike. If for example you want to predict the income of a person (dependent) in relation to age, education level ( independent) , descriptive statistics may be used to describe both type of variables the age of the sample or the levels of income.

DS are used basically to summarize data or to make it more simple to analyze.

c. 27 units.

step-by-step explanation:

we are told that in circle a, ∠bae ≅ ∠dae.

we can see from our given diagram that in and ;

, as these are radii of our given circle.

therefore, by sas congruence postulate.

hence, side be will be equal to side de as corresponding parts of congruent triangles are congruent. so we can set an equation to find the value of x as:

now let us substitute x=17 in the expression for the length of be.

therefore, length of be will be 27 units and option c is the correct choice.
