First lets find the probability of landing tails. Because there is 1 way to get tails and 2 possible outcomes, the probability is 1/2.
Now, lets find the probability of selecting a 9. Since this includes 0, there are 10 possible outcomes and 1 way to get a 9, so the probability is 1/10.
To find them combined, multiply:
1/2 * 1/10
1/20
0.05

Answer:
B.
Step-by-step explanation:
Given,
The time for set up the game = 
minutes,
Also, the time for each level of game is 
minutes,
If there are l levels of games,
Then the time taken in all levels of game = 
<em>
</em>
Hence, the total time ( in minutes ) = Set up time + time in all level
= 
We have 60-minute of free trial of the game,
So, the total time taken can not be exceed to 60 minutes,
= 
Which is the required inequality.
Option 'B' is correct.
It would be 5%. I know the answer is right I just don’t know how to explain it. Sry. But I hope this helps.

Answer:
BC = 1.71
Step-by-step explanation:
well to start we have to know the relationship between angles, legs and the hypotenuse in a right triangle
α = 70°
a: adjacent = BC
h: hypotenuse = 5
sin α = o/h
cos α= a/h
tan α = o/a
we see that it has (angle, adjacent, hypotenuse)
we look at which meets those data between the sine, cosine and tangent
is the cosine
cos α = a/h
Now we replace the values and solve
cos 70 = a/5
0.34202 = a/5
0.34202 * 5 = a
1.7101 = a
round to the neares hundredth
a = 1.7101 = 1.71
BC = 1.71
