According to the complex conjugates theorem, if 5-i5 − i is a root of a function what else is a root?

Ad libitum [116K]

Answer:

5 + i

Step-by-step explanation:

The complex conjugates theorem states that if (a + ib) is a root of a polynomial equation then the complex conjugate (a - ib) will also be its root.

Now, in our case (5 - i) is a root of a polynomial.

The complex number (5 - i) has conjugate and it is (5 + i).

Therefore, (5 + i) will also be a root of the same polynomial. (Answer)

Listed below are the annual tuition amounts of the 10 most expensive colleges in a country for a recent year.

Answer:

$\bar X = \frac{52384 +54079 +52762 +54364 +52584+53987 +53108 +51588 +50554 +53987}{10}=52939.7$

$Mode= 53987$

$Median = \frac{52762+53108}{2}=52935$

$Midrange=\frac{50554+54364}{2}=52459$

Step-by-step explanation:

We can calculate the mean with the following formula:

$\bar X = \frac{\sum_{i=1}^n X_i}{n}$

And if we replace the values given we got:

$\bar X = \frac{52384 +54079 +52762 +54364 +52584+53987 +53108 +51588 +50554 +53987}{10}=52939.7$

The mode is the most repeated value and for this case with a frequency of 2 the mode is:

$Mode= 53987$

In order to find the median we need to order the dataset on increasing way like this:

50554, 51588, 52384 ,52584, 52762

53108, 53987 , 53987 , 54079, 54364

Since we have 10 values an even number the median is calculated from the average between positions 5 and 6 on the data ordered, and we got:

$Median = \frac{52762+53108}{2}=52935$

The mid range is defined like this:

$Midrange = \frac{Max +Min}{2}$

And if we replace we got:

$Midrange=\frac{50554+54364}{2}=52459$

Team rise over run canoed 15 3/4 miles in 2 1/4 hours what was the average rate of speed in miles per hour

frosja888 [35]

Hi there! To do this, we can divide both fractions. We have to convert the fractions into improper fractions. 15 3/4 (63/4) and 2 1/4 (9/4). To divide fractions, keep the first fraction the same, change division into multiplication, and flip the second fraction over. 63/4 * 4/9 is 252/36 or 7 when simplified. The average rate of speed was 7 miles per hour.
