2x + x = 135
3x = 135
x = 135 /3
x = 45

Nijah = 2*45 = 90 miles

Two events, A and B, are independent of each other. P(A)=– and P(A and B)

Georgia [21]

Answer:

D: 0.75

$P(B) = \frac{6}{8} = 0.75$

Step-by-step explanation:

<u>Explanation</u>:-

<u><em>Independent events:</em></u>

If the occurrence of the event 'B' is not effected by the occurrence or non- occurrence of the event 'A' then the event 'B' is said to be independent of 'A'

or

<em>The two events are independent if the incidence of one event is not affect the probability of other event.</em>

<em>P(A∩B) = P(A) P(B)</em>

Given data A and B are independent events

Given data

$P(AnB) = \frac{1}{8} and P(A) =\frac{1}{6}$

we know that A and B are independent events are

P(A∩B) = P(A) P(B)

$\frac{1}{8} = \frac{1}{6} P(B)$

Now calculation we get

$P(B) = \frac{6}{8} = 0.75$

<u><em>Final answer:</em></u>-

$P(B) = \frac{6}{8} = 0.75$

Which of the following equations can be used to find the length of BC in the triangle below??? Help :)

vivado [14]

Answer:

D

Step-by-step explanation:

Using Pythagoras' identity on the right triangle

The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, hence

(BC)² = 10² + 30² → D
