So... 7 to the 6th power is 7^6 =<span>117649 and multiply that with 7^5 power 16807... will give you.. </span>1977326743.. are you sure you want to multiply it? :o
The mean absolute deviation of the number of books is 1.84
<h3>How to determine the mean absolute deviation?</h3>
The dot plot of the number of books is in the attached figure.
From the figure, we have:
x f
1 1
2 2
3 2
4 3
5 1
6 2
7 3
8 1
Start by calculating the mean using:

So, we have:

Evaluate the sum and products

Divide

The mean absolute deviation is then calculated as:

So, we have:

Evaluate the absolute difference

Evaluate the sum of products

Divide

Hence, the mean absolute deviation of the number of books is 1.84

Answer:

Step-by-step explanation:
We are given the equation:

First, we can divide everything by 2:

Notice that we have an equation in quadratic form. Namely, if we make a substitution where u = sin(x), we acquire:

Solve for u. Factor:

Zero Product Property:

Solving for both cases:

And by substitution:

For the first case, recall that sin(x) is -1/2 for every 7π/6 and every 11π/6. Hence, for the first case, our solutions are:

Where n is an integer.
For the second case, sin(x) is -1 for every 3π/2. Thus:

All together, our solutions are:

Answer:
= 0.315

Answer:
No. Steven is not correct.
Step-by-step explanation:
The area of shape A is 15 (either multiply 5 x 3 or just count squares). The area of shape B is 9.
15 is not double 9.
