A blue whale is the largest marine mammal. A random sample of 10 blue whales had a mean lung capacity of 5,000 liters and a standard deviation of 600 liters. Find the lower bound of a 95% confidence interval of the lung capacity (round off to the nearest integer).Assume normal population.

this doesn't make sense lol

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.

not sure but it may be b, as i said i'm not sure.
