Someone please help me out!!! A sinusoidal function repeats itself every 40 seconds, has a maximum
height of 10 m, and a minimum height of 6 m. At time t=0, the function's
height is at its maximum value. *
A) f(x) = 2 sin(9x) + 6
B) f(x) = 2 sin(9x) + 8
C) f(x) = 2 cos(9x) + 8
D) f(x) = 2 cos(9x) + 6

d) 5/12​

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

Drinks:

Five diet, 10 regular.

Probability of a regular drink:

10/(10+5) = 10/15 = 2/3

Regular bag of chips:

6 fat-free, 10 regular

Probability of a regular bag of chips:

10/(10+6) = 10/16 = 5/8

What is the probability that you will buy a regular drink and a regular bag of chips?

Drink and chips are independent events, which means that we just multiply the probabilities. So

The correct answer is given by option d.
