Answer

$y = 28 \sin(\frac{\pi}{6} - \frac{2\pi}{3}) + 49$

Step by Step Explanation

Given

See attachment for table

Required

Determine the sinusoidal function

The sinusoidal function is represented as:

$y = A \sin(Bx + C) + D$

Where

$|A| = Amplitude$

And it is calculated as:

$A = \frac{1}{2}[Highest - Least]$

From the table:

Highest = 77 and Least = 21

So:

$A = \frac{1}{2}[77 - 21]$

$A = \frac{1}{2}[56]$

$A = 28$

B is calculated as:

$Period = \frac{2\pi}{B}$

The period is 12 i.e. 12 months

So:

$\frac{2\pi}{B} = 12$

$B = \frac{2\pi}{12}$

$B = \frac{\pi}{6}$

C is calculated as:

$\frac{C}{B} = -4$

$C = -4 * B$

$C = -4 * \frac{\pi}{6}$

$C = -2 * \frac{\pi}{3}$

$C = -\frac{2\pi}{3}$

Lastly, D is calculated as:

$D = Least + A$

So:

$D =21 + 28$

$D=49$

So, the function is:

$y = A \sin(Bx + C) + D$

$y = 28 \sin(\frac{\pi}{6} - \frac{2\pi}{3}) + 49$

mafiozo [28]

Answer:

25%

Step-by-step explanation:

Height of all the bars in chart = 2 or more is 10, 3, 1.

Add all the bars to give us exact amount of data required = 10 + 3 + 1 = 14

Total number of students in class = 56

Percentage of class having two or more student = (14/56) * 100% = 25%

Answer: 2/5 = 0.4 = 40%

Step-by-step explanation:

Each sector has an equal area, so each sector has an equal chance of being landed on. There are two shaded sectors and 5 total, so there is a 2 out of 5 chance that the spinner will land on a shaded one.
