Answer:

<h2>C : None of the above</h2>

Step-by-step explanation:

A : -2+(-2) = 0 False

-2+(-2) = -4

A negative plus a negative is actually a negative. When adding signed numbers, it is useful to think of positive numbers as gains and negative numbers as losses.

B : 2-(-2) = 0 False

2-(-2) = 4

Because there is subtraction sign so if subtraction sign added to negative sign it makes positive from 2-(-2) it will be 2+2

Events A and B are independent. Find the missing probability. Enter your answer as a decimal rounded to two places.

Leya [2.2K]

ANSWER

$P(not \: B) = \frac{1}{4}$

EXPLANATION

If A and B are independent events, then

P(A and B)=P(A)×P(B)

$\frac{3}{10} = \frac{2}{5} \times \: P(B)$

Multiply both sides by;

$\frac{5}{2}$

$\frac{5}{2} \times \frac{3}{10} = \frac{5}{2} \times \frac{2}{5} \times \: P(B)$

$\frac{3}{4} =P(B)$

$P(not \: B) = 1 - P(B)$

$P(not \: B) = 1 - \frac{3}{4}$

$P(not \: B) = \frac{1}{4}$

Find the missing side of the triangle. A. 321−−−√ yd B. 221−−−√ yd C. 338−−√ yd D. 21−−√ yd

antoniya [11.8K]

Answer:

$x = \sqrt{221} yd$

Step-by-step explanation:

Use Pythagorean theorem to find x.

Thus, the sum of the square of the lengths of two legs of a right triangle equal the square of the hypotenuse, which is the longest side.

Thus,

$x^2 = 11^2 + 10^2$

$x^2 = 121 + 100$

$x^2 = 221$

$x = \sqrt{221} yd$
