Answer:
0.18173219.
Step-by-step explanation:
We have been asked to find what will be the probability that at least 6 of 9 adults use their smartphones in meetings or classes.
We will find our answer using Bernoulli's trails.
First of all we will find the probabilities when r is 6, 7,8 and 9 then we will add them all.
When r=6,
Similarly we will find Probabilities when r=7, 8 and 9.
When r=7
When r=8
When r=9,
Now let us add all the probabilities to get the final answer.
Therefore, probability that at least 6 of 9 adults use their smartphones in meetings or classes is 0.18173219.
Answer:
x = the number
Step-by-step explanation:
15.) 2x + 9 = 25
16.) 3x - 6 = 21
17.) 7x = 12 + 3x
18.) 4x = 18 + x
19.) 2x + 24 = 8x
20.) 30 - x = 4x
If you are rounding to the nearest tenth it would be 8.5.
You can’t round to the nearest ten with 8.546
Answer: v = - 9
Step-by-step explanation:
Since two points on the line are given, we use formula for slope.
Let (a,b) and (c,d) be two points on the line, the slope of the line is given by
m=
.
Hence, using this we have
-4=
Thus, we have
-4×(-3)=3-v⇒12=3-v⇒12-3=-v⇒v=-9
