Option: C is the correct answer.
C. Periodic with period 4 and amplitude of about 15.
Step-by-step explanation:
We are given the table of values as:
Hour 1 -- 2 -- 3 -- 4 -- 5 -- 6 -- 7 -- 8 -- 9 -- 10 -- 11
Number 24-41-10-32-26-38-9-31-25-39-12
of boats
As we could see that after every 4 value the values are approximately repeating.
Hence,the data set is approximately periodic.
Also, the amplitude is calculated as:
Average of the maximum and minimum value of each set
We divide the set into 3 sets as follows:
Hour 1 2 3 4
Number of boat 24 41 10 32
Here we have amplitude as:
(41-10)/2=15.5
Hour 5 6 7 8
Number of boat 26 38 9 31
Amplitude is:
(38-9)/2=14.5
Hour 9 10 11 12
Number of boat 25 39 12
Amplitude is:
(39-12)/2=13.5
Hence, we see that the amplitude is about 15.
Answer:x=3/9
Step-by-step explanation:
X directly proportional to Y
X=ky
Make k the subject of formula
k=x/y
K=27/81
Divided by 9
K=3/9
<span>if it is travelling 20 feet in 1/5 of a second that means that in 1 second (which is 5 times as much as 1/5 of a second) it will do 5 times 20 feet hence 100 feet. Then in 3 seconds it will do 300 feet</span>
Answer:
a. 6 feet
b. The length of the angle bisector of angle A is approximately 7.81 feet
Step-by-step explanation:
a. The given parameters of the right triangle ABC are;
The length of the leg AC = 5 ft.
The length of the hypotenuse AB = 13 ft.
Therefore, the length of the side BC = √((AB)² - (AC)²) = √((13 ft.²) - (5 ft.²)) = 12 ft.
The length to the middle of the side BC = BC/2 = (12 ft.)/2 = 6 ft.
b. The length of the angle bisector of angle A = The the length of the median from A to the side BC = √((BC)/2)² + (AC)²)
BC = √(((12 ft.)/2)² + (5 ft.)²) = √61 ft. ≈ 7.81 ft.
