One dimension of bird beaks is "depth"--the height of the beak where it arises from the bird's

head. During a research study on one island in the Galapagos archipelago, the beak depth of all

Medium Ground Finches on the island was found to be normally distributed with mean y = 9.6

millimeters and standard deviation o=1.1 millimeter. What is the probability that the mean

depth in 15 randomly selected Medium Ground Finches is at least 10 millimeters?

answer:   28.56 feet (approx)

step-by-step explanation:

since, triangle abc has measure of angle c equal to 55 degrees, measure of angle abc equal to 90 degrees, and length of bc equal to 20 feet.

we have to find out the measurement of segment ab.

therefore, tan 55° =

but bc = 20 feet.

⇒ tan 55 ° =  

⇒ ab = 20 × tan 55 °

⇒ ab = 20 × 1.42814800674

⇒ ab = 28.5629601348   ≈ 28.56 feet
