Answer:
121
Step-by-step explanation:
Answer: The probability that none of the calls would result in a reservation would be 0.72%.
Since there is an 18% chance that there would be a reservation, then there is a 72% chance that there is not a reservation.
Our goal is to determine the likelihood that there are no calls. Or that the 72% chance event happens 15 times.
We can use the following expression to find that repeated probability.
(0.72)^15 = 0.0072 or 0.72%
Answer:
7 months
Step-by-step explanation:$90 / $18 = 5 months + 2 months free = 7 months
Answer:
Starling's law of the heart.
Step-by-step explanation:
Answer:
14.15ft
Step-by-step explanation:
Attached is a visual representation of our scenario.
The green line represents the line of sight of the bird, and the green angle represents the angle of depression. It goes downwards because it says "depression."
As you can observe, the scenario creates a right triangle, where the alternate interior of the angle is found in the triangle.
Using Trigonometric Functions, or SOHCAHTOA, we can solve for the distance between the bird and the food, which in this case is the hypotenuse(H) of the triangle. Looking at the diagram again, we can see that 11ft was also given, which can be represented as the adjacent (A) side of the triangle. It is adjacent because it is right next to the angle given.
Because we have an angle and the adjacent side, we will use CAH.
Given:
A= 11ft
H = x
θ = 39°
Solution:
CAH
The bird is 14.15 ft away from the food.
