Answer:

Step-by-step explanation:
So we have the inequality:

Definition of Absolute Value:

Note that the sign is flipped in the second case because we multiplied by a negative.
Add 5 to both sides to both equations:

Merge:

And we're done!
2x + 40
Divide both sides by 2
You get x + 20
Answer:
Z and B are independent events because P(Z I B) = P(Z)
Step-by-step explanation:
- If Z and B are independent, Z does not affect B and B does not affect Z.
- This means that, to know something about B does not help predicting Z, and to know something about B does not help predicting Z.
- Then, the probability P (Z/B) = P(Z) because B does not add any information about Z, therefore, the probability of Z only depends on itself.
Given number is 78/14.
We have to find two whole numbers between which given number 78/14 lies.
Let's convert that into mixed fraction.
To do that we divide 78 by 14 to find the quotient.
We see that 14 goes 5 times into 78 and leaves remainder of 8.
So we can rewrite 78/14 as
.
means little more than 5 but less than 6.
So required two whole numbers are 5 and 6.
Answer:
The number of desktop internet users are 3 times more than the number of mobile internet users.
Step-by-step explanation:
We are given the following in the question:
Number of mobile internet users = 400,000,000

Number of desktop internet user =

Comparison of values:

Thus, the number of desktop internet users are 3 times more than the number of mobile internet users.
