Which of the following would best represent a cosine function with an amplitude of 2, a period of pi over 3, and a midline at y

OleMash [197]

C. f(x) = – 2 cos 6x + 1

Start by determining the amplitude. Since we've deduced the amplitude is 2, the equation can include either a positive or negative 2 (since amplitude measures absolute value).

Next is the period. The equation for period P is P = (2pi)/b. If P is pi/3, then
pi/3 = (2pi)/b. Thus your b value should be 6.

Finally, the midline would be given by + 1 since adding a unit shifts the function upwards. This means that instead of the highest y value being 2 and the lowest -2, instead you'd have values of 3 and -1.
(3 – 1)/2 = 1 (midpoint theory).

What is the mean absolute deviation of the data set? {12, 10, 10, 8, 6, 7, 7, 12}

Simora [160]

Answer:

The MAD of {12, 10, 10, 8, 6, 7, 7, 12} is 2.

Step-by-step explanation:

<u><em>Step 1 : Add all the values Up:</em></u>

<u><em /></u> $12+10+10+8+6+7+7+12=72$

<u><em>Step 2 : Divide them by the number of items or numbers:</em></u>

<u><em></em></u> $\frac{12+10+10+8+6+7+7+12}{8}=9$ <u><em></em></u>

<u><em></em></u>

<u><em>Step 3: Find the absolute deviations:</em></u>

<u><em></em></u> $12-9=3\\10-9=1\\10-9=1\\9-8=1\\9-6=3\\9-7=2\\9-7=2\\12-9=3\\$ <u><em></em></u>

<u><em>Step 4: Add all the absolute deviations:</em></u>

$3+1+1+1+3+2+2+3=16$

<u><em>Step 5: Find the mean:</em></u>

$\frac{3+1+1+1+3+2+2+3}{8}=2$
