Answer:
b 15 - 4i sqrt(2)
Step-by-step explanation:
15 - sqrt (-32)
15 - sqrt(-1) sqrt(32)
15 - ±i sqrt(16) sqrt(2)
15 - ±4i sqrt(2)
Taking the principal square root
15 - 4i sqrt( 2)
The phrases that are inequalities are:
B) -2 < 2
D) 7w > 5.6
E) f - 4 - 7 > 7 - 4 - f
<h3>
</h3><h3>Which of the following phrases are inequalities?</h3>
First, we define an equation as:

Where P and Q are two expressions.
On the other hand, an inequality can be:

These are inequalities because now the expressions P and Q can (and in some cases must) be different.
With that in mind, the phrases that are inequalities are:
B) -2 < 2
D) 7w > 5.6
E) f - 4 - 7 > 7 - 4 - f
As you can see, in these 3 we have the "lower than" or "larger than" symbols used, so these represent inequalities.

Answer:
10 miles
Step-by-step explanation:
5 1/4+ 4 3/4 = 10
First, we calculate for the variance by dividing the given sum of the squared deviations by the number of data.
variance = (316) / 9 = 316/9
Then, get the square root of the answer to calculate for the standard deviation.
sd = sqrt (316/9) = 5.93
Thus, the standard deviation is approximately 5.93.
