formula: pi • radius squared • height
Answer:
y = 5 cos ((2π/3)x - 2) + 2
Step-by-step explanation:
Cosine function takes a general form of y = A cos (Bx + C) + D
Where
A is the amplitude
2π/B is the period
C is the phase shift ( if -C, then phase shift right, if +C phase shift left)
D is the vertical displacement (+D is above and -D is below)
Given the conditions of the function to build and the general form, we can write:
** Note: period needs to be 3, so 2π/B = 3, hence B = 2π/3
Now we can write:
y = 5 cos ((2π/3)x - 2) + 2
first answer choice is right.
Answer:
b. 0.055
Step-by-step explanation:
The point estimate of the proportion of people who wear hearing aids is
The number of people in the sample who wear hearing aids divided by the total number of people in the sample.
In this problem, we have that:
Sample of 855.
47 people in the sample had hearing aids.
47/855 = 0.0549
Rounding up
0.055
So the correct answer is:
b. 0.055

Answer:
$3.583
Step-by-step explanation:
Given the monthly stock prices :
January = $3.50
February = $2.25
March = $5.00
The average monthly change in price of XYZ stock from. JANUARY through MARCH is;
(January + February + March) / 3
Average monthly change :
(3.50 + 2.25 + 5.00) / 3
$10.75 / 3
= $3.583
