20 POINTS PLZ HURRY!!! (04.02 MC)
As a special promotion for its 16-ounce bottles of fruit juice, a juice drink company printed a message on the inside of each cap. Some of the caps read, "Better luck next time!" whereas others read, "You won!" The company advertised the promotion with the slogan "One in seven wins a prize!" Suppose the company is telling the truth and that every 16-ounce bottle of juice has a one-in-seven chance of being a winner. Eight friends each buy one 16-ounce bottle of juice at a local convenience store. Let X equal the number of friends who win a prize.

Part A: Explain why X is a binomial random variable. (3 points)

Part B: Find the mean and standard deviation of X. Interpret each value in context. (4 points)

Part C: The store clerk is surprised when two of the friends win a prize. Is this group of friends just lucky, or is the company's one-in-seven claim inaccurate? Compute P(X ≥ 2) and use the result to justify your answer. (3 points) (10 points)

what is the answer?

p ÷ r = tan(x)

step-by-step explanation:

given that there is a figure below shows a right triangle: a right triangle is shown with hypotenuse equal to q units and the length of the legs equal to p units and r units.

graph is missing so i will create the graph as per given information.

the angle between the legs having lengths p units and q units is y degrees. the angle between the legs having lengths r units and q units is x degrees.

now we need to find about what is p ÷ r equal to.

so we can use trigonometric ratio tan(x)=[altitude]/[base] to find the value of p ÷ r, because p is the altitude and r is the base.

p ÷ r=tan(x)

hence final answer is p ÷ r=tan(x).
