Answer:
60%
Step-by-step explanation:
If I get you right, you're asking for the percentage gain to the nearest percentage, right?
Now to do this, we need to get the amount of profit she made. That's quite easy, we only need to subtract the cost price from the selling price. And that equals $15 - $9.38 that equals $5.62.
Now, we divide this value by the cost price and multiply by 100% to get the percentage gain.
I.e 5.62/9.38 × 100%.
That gives 59.9% , which equals 60% when approximated to the nearest percentage.
Find the mean absolute deviation for the data set. {3, 5, 6, 3, 2, 2, 1, 0, 0, 4, 7, 4, 5, 5, 6}

Answer:
0.50
Step-by-step explanation:
The mean = 3 + 5 + 6+ 3 +2+ 2+ 1+0+ 0+ 4+ 7+ 4+ 5 + 5 + 6) / 15
= 53/15
= 3.533
Difference of values from the mean:
<u> n </u> <u> n - 3.533</u> (Absolute value)
3 0.533
3 0.533
6 2.467
3 0.533
2 1.533
2 1.533
1 2.533
0 3.533
0 3.533
4 0.467
4 0.467
5 1.467
5 1.467
6 2.567
7 3.467
Totals:
53 26.533
So the M.A.D. = 26.533 / 53 = 0.50
Answer:
a=2.5!
Step-by-step explanation:
In this question, we are given a matrix, and we have to perform the given operation.
The matrix is:
![\left[\begin{array}{ccc}6&-1&|5\\1&-5&|0\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D6%26-1%26%7C5%5C%5C1%26-5%26%7C0%5Cend%7Barray%7D%5Cright%5D)
The following operation is given:
![R_1 \rightarrow -6R_2 + R_1](https://tex.z-dn.net/?f=R_1%20%5Crightarrow%20-6R_2%20%2B%20R_1)
In which
is the element at the first line and
is the element at the second line.
Updating the first line:
![R_{1,1} = -6*1 + 6 = 0](https://tex.z-dn.net/?f=R_%7B1%2C1%7D%20%3D%20-6%2A1%20%2B%206%20%3D%200)
![R_{1,2} = -6*-5 - 1 = 30 - 1 = 29](https://tex.z-dn.net/?f=R_%7B1%2C2%7D%20%3D%20-6%2A-5%20-%201%20%3D%2030%20-%201%20%3D%2029)
![R_{1,3} = -6*0 + 5 = 5](https://tex.z-dn.net/?f=R_%7B1%2C3%7D%20%3D%20-6%2A0%20%2B%205%20%3D%205)
Thus, the filled matrix will be given by:
![\left[\begin{array}{ccc}0&29&|5\\1&-5&|0\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D0%2629%26%7C5%5C%5C1%26-5%26%7C0%5Cend%7Barray%7D%5Cright%5D)
