If the probability of an event is what is the probability of the event not happening?20/69Write your answer as a simplified frac

Vilka [71]

If an event has a probability P of happening, then there is a probability of (1-P) of the event not happening.

In this case the probability of the event is p=20/69.

Then, the probability of the event not happening is:

$P(\text{not happening})=1-p=1-\frac{20}{69}=\frac{69-20}{69}=\frac{49}{69}$

Answer: the probability of the event not happening is 49/69.

How do I solve this? 408=1/2(b)(17)

seropon [69]

Answer:

Step-by-step explanation:

Given: $408 = \frac{1}{2} \times (b) \times (17)$

Now, solving it.

We first open parenthesis which is (b) $\times$ (17) = $17b$

Next Multiply both side by 2

⇒ 816 = $17b$

Now, we will divide both side by 17

∴ b $= 48$

What is the distance of this line?<br><br>Which is the right answer?

Shtirlitz [24]

Answer:

Step-by-step explanation:

We can use the distance formula derived from the Pythagorean theorem

D = $\sqrt{(x_2-x_1)^2 +(y_2-y_1)^2}$

the two points given are

(0, 3) and (-2, -3)

$(x_2-x_1) = (0-(-2)) = 2\\(y_2-y_1) = (3-(-3)) = 6\\D = \sqrt{(2)^2 + (6)^2} \\D = \sqrt{4 + 36} \\D = \sqrt{40} = 6.324$
