The four blood types are a, b, o, and ab. given the percent blood types for people in a certain country, calculate the percent of the
country's population with ab blood type. recall that 1 = 100%. this means that 1 whole is 100%

The percent of the country's population with AB blood type is 9% .

Step-by-step explanation:

Given:

Recall that 1 = 100%. This means that 1 whole is 100%.

Given the percent blood types for people in a certain country:

Blood Type                Percent

A                                   42%  

B                                   16%

O                                   33%

AB                                AB

Now, to calculate the percent of the  country's population with AB blood type:

So, getting the total percent of Blood types A, B and O:

Now, to get the percent of AB blood type we subtract the total percent of blood types from the whole that is 100% (as given) :

Therefore, the percent of the country's population with AB blood type is 9% .

answer:  

step-by-step explanation:

here x represents the height of the pole,

and, the height of the shadow of the pole is 12 feet.

also, the angle of elevation from the top of the pole is 40°,

therefore,

by the low of sine,

which is the required equation for finding the value of x,
