The mean and mean absolute deviation of the given data are;

B. Mean: 72; mean absolute deviation: 2.

The mean absolute deviation of a data set is the average distance of each data point in the data set from the mean of the data set.

Given the data, 68, 70, 72, 73, 74, 75:

Mean = (68 + 70 + 72 + 73 + 74 + 75)/6 = 432/6

Mean = 72

Mean absolute deviation = [(68 - 72) + ( 70 - 72) + ( 72 - 72) + ( 73 - 72) + ( 74 - 72) + ( 75 - 72)] / 6

Mean absolute deviation = [(4) + (2) + (0) + (1) + (2) + (3)] / 6

Mean absolute deviation = 12/6

Mean absolute deviation = 2

Step-by-step explanation:

I assume you mean [tex]h(t)=8\cos(\frac{\pi}{10}t)[/tex] for your function.

As the given function is in the form of [tex]f(t)=a\cos(bt+c)+d[/tex] (some textbooks may write this formula differently), the period is equal to [tex]\frac{2\pi}{|b|}[/tex]. Hence, the period of the given function is [tex]\frac{2\pi}{|\frac{\pi}{10}|}=\frac{2\pi}{1}*\frac{10}{\pi}=\frac{20\pi}{\pi}=20[/tex], or 20 seconds.

The period of the function that relates the sea level as the function of time is given by: Option D: 20 seconds.

Suppose that we've got: [tex]f(x) = a\cos\left(\dfrac{2\pi x}{b}\right)[/tex]

Then, this function has:

For this case, we're given that:

[tex]h = 8\cos\left(\dfrac{\pi x}{10}\right)[/tex]

We can rewrite it as:

[tex]h = 8\cos\left(\dfrac{2\pi x}{20}\right)[/tex]

Thus, we get a = amplitude = 8 units(distance), and b = period = 20 units(time in seconds).

Thus, the period of the function that relates the sea level as the function of time is given by: Option D: 20 seconds.

Answer:

[tex]\frac{1}{2}x[/tex]

Step-by-step explanation:

If the greater number is x and it is two times greater than the other number then the other number is half as big.  This is true because 2*[tex]\frac{1}{2}[/tex]x = x

The other number is equal to x/2.

A fraction in mathematics represents a portion or element of the whole. It represents the appropriate parts of the totality. A fraction is made up of two parts: the numerator and the denominator.

As per the given data:

We are given the relationship between 2 numbers, It's given that One number is two times greater than another number.

The greater number = x

Let's assume that the smaller number is y.

From the given data in the question:

One number is two times greater than another number

= x = 2y ...(i)

The other number that is the smaller number is given by:

By dividing eq (i) by 2 from both sides.

y = x/2

The other number is equal to x/2

Hence, The other number is equal to x/2

For average daily balance:

Form date 9/1 to date 9/5 :

Balance x number of the days = $ 387.52 x 5 days = $ 1937.6

As on date 9/6 :

($ 387.52 - $ 50.00) x 1 day = $ 337.52

From date 9/7 to date 9/18 :

Balance = $ 337.50

Number of days = 12 days

Therefore, product = 12 days x $ 337.52

= $ 4050.24

As on 9/19 :

($ 337.52  + $ 62.66) x 1 day = $ 400.18

From date 9/20 to date 9/30

Balance :$ 400.18

Number of days = 11 days

Therefore, product = 11 days x $ 400.18

= $ 4401.98

Average daily balance

=  ($ 1937.6 +  $ 337.50 + $ 4050.24 + $ 400.18 + $ 4401.98) / 30

To simplify: 8s - 11s + 6s. Simplify the like terms by combining them

Simplifying 8s - 11s + 6s will give 3s.

Given,

8s - 11s + 6s

Now,

Expression : 8s-11s+6s

To simplify the expression combine like terms. So, all the terms consists of variable s.

Combine all terms having same sign,
