Tossing a fair coin has outcomes {1, 2, 3, 4, 5, 6} with a mean of 3.5 and a standard deviation of 1.708. If a fair coin is thrown three times, and the mean of the resulting triplet is calculated, the mean an standard deviation of the set of means from all possible triplets is:

step-by-step explanation:

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.

add the numbers under frequency to find the total number:

5 + 8 +7 + 4 + 0 +1 = 25

the answer is 25.
