Answer:

Option B. -4x² - 11x + 13

Step-by-step explanation:

Given polynomials are ( -x² + 9 ) and ( -3x² - 11x + 4 )

We have to add them.

( -x² + 9 ) + -3x² - 11x + 4 )

-x² + 9 - 3x² - 11x + 4

Now we will collect similar terms

( -x² - 3x² ) - 11x + ( 9 + 4 )

-4x² - 11x + 13

Therefore, option B is the answer.

All of number one thank you
Vadim26 [7]
I'm going to divide number one to 6 parts
1. \frac{4}{10} = \frac{40}{100}
2. \frac{7}{10} = \frac{70}{100}
3. \frac{2}{10} = \frac{20}{100}
4. \frac{9}{10} = \frac{90}{100}
5. \frac{18}{10} = \frac{180}{100}
6. \frac{26}{10} = \frac{260}{100}

because to make the denominator to 100, you need to multiply 10 by 10 which is 100.
and because you multiply 10, you also have to multiply the numerator by 10.
EXAMPLES: \frac{3}{10} = \frac{3}{10} × \frac{10}{10} = \frac{30}{100}

Explain the relationship between variance and standard deviation. Can either of these measures be negative? Explain.
jarptica [38.1K]
<span>Standard deviation is the square root of variance. Variance is always a non-negative number, since you can't take the square root of a negative number. So neither can be negative </span>
