A study of 1000 randomly selected flights of a major airline showed that 769 of the flights arrived on time. What is the probability of a flight being delayed?

There are 23.1% probability of flights getting delayed.

Step-by-step explanation:

Given:

Number of samples of flights selected = 1000

Number of flights arrived on time = 769

We need to find the probability of flight being delayed.

Solution:

Now we will first find the number of flights which are delayed.

number of flights which are delayed can be calculated by subtracting Number of flights arrived on time from Number of samples of flights selected.

framing in equation form we get;

number of flights which are delayed =

Now we will find the probability of flight being delayed.

probability of flight being delayed can be calculated by dividing number of flights which are delayed from the Number of samples of flights selected  and then multiply by 100.

framing in equation form we get;

probability of flight being delayed =

Hence There are 23.1% probability of flights getting delayed.

(1, –1), (16, –4), (36, –6)

step-by-step explanation:

given that the function is

this can also be written as

we have to graph this function and check which list of points lie on the graph

see attachment for graph:

we find that the points lying are (1,-1) (16,-4) and (36,-6)

since square root is there we find that x can only be posiitve but y can be since square root both positive and negative.
