hospital director wishes to estimate the mean weight of babies born in the hospital. How large a sample of birth records should be taken if she/he wants a 99% CI of 2 wide? Assume that a reasonable estimate of population standard deviation is 5.

1/2*qr*rs

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.

table a is wierd
