Explanation: When you toss two coins, the possible outcomes can be:

1) A head followed by a head.
2) A head followed by a tail.
3) A tail followed by a head.
4) A tail followed by a tail.

Therefore,
Total possible outcomes = 4

Now, the given condition is a head followed by a tail. In the possible outcomes there is only one (i.e; 2) that satisfies this condition.

Therefore, outcome of getting head followed by tail = 1

Finally,
P(getting head followed by tail) = outcome of getting head followed by tail / Total possible outcome.

Which is 1/4.

Hope this helps.

Answer:

1/4

Step-by-step explanation:

HT represent the probability of tossing a head then Tail.

There is 4 possible results and only 1 give us HT.

We call this theoretical probability. which is

\frac{x}{y}

where x is favorable outcomes and y is total number of outcomes.

So there is a 1/4 probability of getting a head followed by a tail.

Answer:

The answer to your question is below

Step-by-step explanation:

Use trigonometric functions to find x

13.  cos 40 = 5/x

     x = 5 / cos 40

     x = 5 / 0.766

     x = 6.5

14. tan 25 = x/9

     x = 9tan 25

     x = 9(0.466)

     x = 4.2

15.- cos 65 = x/12

      x = 12 cos 65

      x = 12 (0.423)

      x = 5.1

16.- sin 32 = 15/x

      x = 15 / sin 32

      x = 15 / 0.53

      x = 28.3

17.- tan 55 = 20 / x

      x = 20 / tan 55

      x = 20 / 1.42

      x = 14

18.- sin31 = x / 18

     x = 18 sin 31

     x = 18 (0.52)

     x = 9.3

Solve the system by elimination. . 4x-9y=-21 , -4x-3y=9
Ivan
(-3, 1)
4x-9y=-21
+-4x-3y=9
-12y= -12
y=1

4x- 9(1)= -21
4x-9=-21
+9 +9
4x= -12

3x - 20 = 4 PLEASE EXPLAIN HOW YOU GOT THE ANSWER IN STEPS!
sammy [17]

Answer:

x = 8

Step-by-step explanation:

3x - 20 = 4

add 20 to both sides

3x - 20 + 20 = 4 + 20

3x = 24

divide both sides by 3

\frac{3x}{3} = \frac{24}{3}

x = 8
