Answer:

The probability is 1/8 or 0.125.

Step-by-step explanation:

Given is that three fair coins are flipped.

And we have to find the probability of getting a head on the first flip,a tail on the second flip, and another head on the third flip.

Firstly, here each flip is independent of the outcome of the other flips.

So, the probability of head is 1/2 and the probability of tail is 1/2.

Therefore, the answer will be : (1/2) (1/2) (1/2)=8

What is the length of EF in the triangle? Show your work. HELP!

Zinaida [17]

The length of EF in the given triangle is 8.80 m.

Step-by-step explanation:

Step 1:

In the given triangle, the opposite side's length is 16.2 m, the adjacent side's length is x m while the triangle's hypotenuse measures 16.2 m units.

The angle given is 90°, this makes the triangle a right-angled triangle.

So first we calculate the angle of E and use that to find x.

Step 2:

As we have the values of the length of the opposite side and the hypotenuse, we can calculate the sine of the angle to determine the value of the angle of E.

$sinE = \frac{oppositeside}{hypotenuse} =\frac{13.6}{16.2} = 0.8395.$
