A random sample of size 81 is taken from an infinite population with a mean of 50 and a standard deviation of 9. Find an approximate probability that the sample mean is within 48 and 51 (round off to second decimal place).

4-64

8-128

all multiples of 16

a. -0.3 > -0.33

w'x is 0.

hope it

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.
