The probability that a randomly chosen citizen-entity of cygnus is of pension age† is approximately 0.7. what is the probability that, in a randomly selected sample of four citizen-entities, all of them are of pension age?

0.2401

Step-by-step explanation:

The binomial distribution formula is given by :-

where P(x) is the probability of x successes out of n trials, p is the probability of success on a particular trial.

Given : The probability that a randomly chosen citizen-entity of Cygnus is of pension age† is approximately: p =0.7.

Number of trials  : n= 4

Now, the required probability will be :

Thus, the probability that, in a randomly selected sample of four citizen-entities, all of them are of pension age =0.2401

step-by-step explanation:

d

step-by-step explanation:

by observation, we can see that the the graph is simply the graph of y = |x| that has been shifted 4 units downwards and 3 units to the left.

we can recognize in choice d :

y = | x + 3 |   - 4 (rewriting in general form)

y = | x - (- 3) |   - 4

the "-4 " term means   that the graph has been shifted by 4 units in the negative y direction

the "-3 " term means   that the graph has been shifted by 3 units in the negative x direction

this matches our observation of the graph described above.
