Find the standard deviation for the group of data items. 12​, 12​, 12​, 14​, 14​, 14
The standard deviation is nothing.
​(Simplify your answer. Round to two decimal places as​ needed.)

answer: ask

step-by-step explanation:

they can both be solutions depends on the equation

step-by-step explanation:

what is the equation? ?

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.
