Which term best describes two events in which knowledge of one event has no effect on the probability of the other event?

1 answer:

5 0

The correct option is the first one. Independent events are exactly what you're asking for: the information you have on one event doesn't affect in any way the probability of the other.

A classic example is the roll of two dice: assume that you roll the first one and get a 4. Does this imply anything on the outcome of the second die? No, all events 1,2,3,4,5,6 are still equally distributed, no matter the result of the first die.

irina [24]

Answer:

-2

Step-by-step explanation:

Given:

Points (2, 6) and (4, 2)

Slope formula:

m = (y2-y1)/(x2-x1)

Using the given points:

m = (2- 6)/(4 - 2) = -4/2 = -2

Your friend incorrectly says the solution to the equation 11.2y - 7.4y=141.36 is y=7.6 what error did your friend make? A) Divid

krek1111 [17]

The correct answer is: D) Subtracted like terms incorrectly

Step-by-step explanation:

Given

$11.2y - 7.4y=141.36$

The terms 11.2y-7.4y need to be subtracted. But option b is to add them. We will add them and then solve the equation to see if its right.

So adding 11.2y-7.4y

$18.6y=141.36$

Dividing both sides by 18.6

$\frac{18.6y}{18.6}=\frac{141.36}{18.6}\\y=7.6$

so by adding the terms instead of subtracting we get y=7.6.

this means that the error was adding 7.4y-11.2y instead of subtracting

The correct method will be:

$11.2y - 7.4y=141.36\\3.8y=141.36$

Dividing both sides by 3.8

$\frac{3.8y}{3.8}=\frac{141.36}{3.8}\\y=37.2$

Hence,

The correct answer is: D) Subtracted like terms incorrectly

Find the value of x in the triangle in the picture.

Flauer [41]

Answer:

X equals 33 degrees

Step-by-step explanation:

Every triangle equals a total of 180 degrees. If you add 114 and 33 you get 147 degrees. You subtract 147 from 180 to get your answer for X, Which is 33 degrees.
