Answer:
Step-by-step explanation:
let the number=x
4>3x-5
9>3x
3x<9
x<3
Using it's concept, it is found that there is a 0.64 = 64% probability that neither flight is delayed.
<h3>What is a probability?</h3>
A probability is given by the <u>number of desired outcomes divided by the number of total outcomes</u>.
In this problem, there are 2 flights, each with a 0.8 probability of being on time. The flights are independent, hence the probability that both are on time is given by:
p = 0.8 x 0.8 = 0.64.

Answer:
6
Step-by-step explanation:
Given
2x - 2y ← factor out 2 from each term
= 2(x - y) ← substitute x - y = 3 into the expression
= 2(3)
= 6
