The binomial coefficient is calculated as:

$nCx=\frac{n!}{x!(n-x)!}$

It means that there are nCx ways to select x elements from a group of n elements.

So, If the researcher wants to determine the probability that 6 out of the next 8 individuals in his community are in favor of the president, we can replace n by 8 and x by 6 and calculated the binomial coefficient as:

$8C6=\frac{8!}{6!(8-6)!}=28$

Given cos A = 0.25 find angle A in degrees. Round your answer to the nearest hundredth.

Fantom [35]

We have that
cos A=0.25
so
A=arc cos (0.25)-------> using a calculator----> A=75.5225°
Round to the nearest hundredth-----> A=75.52²

the answer is
the option <span>75.52°</span>
