Use inverse cos to find the angle.

cos^-1(0.05) = B

B = 87.13401602 (don’t know what place you want the answer to be rounded to, but that’s the answer I get in my calculator.)

Eliminate the parameter. x = t2 + 2, y = t2 - 4

stepan [7]

$\bf \begin{cases}
x=t^2+2\implies x-2=t^2\implies \sqrt{x-2}=\boxed{t}\\\\
y=t^2-4\\
----------\\
y=\left( \boxed{\sqrt{x-2}} \right)^2-4\implies y=x-2-4\\\\
y=x-6
\end{cases}$

just a plain vanilla substitution

According to national data, about 11% of American college students earn a graduate degree. Using this estimate, what is the prob

Mama L [17]

Answer:

Probability is the chances of an event occurring or not occurring in an experiment.

Formula for the probability of A and B (independent events): p(A and B) = p(A) * p(B). If the probability of one event doesn't affect the other, you have an independent event. All you do is multiply the probability of one by the probability of another.

Step-by-step explanation:

P(Exactly 26 undergraduates will earn a degree) = P(26);

P(Sample of Students) = P(200);

P(11% of American students earn a degree) = P(11% or 0.11)

∴ The probability that exactly 26 undergraduate earning a degree = P(200)/P(26) = 7.69

∴ To find the 11% of the American College students that earn a degree =

7.969 x 0.11 = 0.8459≅ 0.9
