I'm not sure if this is simply a true/false question but if so the answer is true. With a standard deviation of 1.8, your tests would always remain in the A range.

Hope that helps.

Answer question showing work 6 − 4n <− 1 − 4n

-Dominant- [34]

Answer:

There are no solutions.

Step-by-step explanation:

6−4n<−1−4n

Step 1: Simplify both sides of the inequality.

−4n+6<−4n−1

Step 2: Add 4n to both sides.

−4n+6+4n<−4n−1+4n

6<−1

Step 3: Subtract 6 from both sides.

6−6<−1−6

0<−7

Simplify this expression<br> 5*sqrt(x^22) where x<0

Doss [256]

Answer:

$\boxed{5x^{11}, x < 0}$

Step-by-step explanation:

$5\sqrt{x^{22}}$

Remember that we evaluate the term under the radical first.

Even though x < 0, x²² > 0

So,

$5\sqrt{x^{22}} = 5x^{11}$

The simplified expression is

$\boxed{5x^{11}, x < 0}$
