The brand name of a certain chain of coffee shops has a 52% recognition rate in the town of coffleton. an executive from the company wants to verify the recognition rate as the company is interested in opening a coffee shop in the town. he selects a random sample of 8 coffleton residents. find the probability that the number that recognize the brand name is not 4. round to three decimal places.

0.728

Step-by-step explanation:

We are given that The brand name of a certain chain of coffee shops has a 52% recognition rate in the town of Coffleton.

A shopkeeper selects a random sample of 8 Coffleton residents.

Now we are supposed to find the probability that the number that recognize the brand name is not 4.

So, probability of success = p = 0.52

So, q = probability of failure = 1-p = 1- 0.52 = 0.48

n = 8

Now find the probability  the number that recognize the brand name is  4.

Formula :

So,

Hence  the probability that the number that recognize the brand name is not 4 is 0.728

x/7.50 = 15

x= 7.50 / 15 divide

step-by-step explanation:

the circle graph is not a function.

step-by-step explanation:

the graph of the circle is not a function.

because for a graph to be a function, each value of x must give one value of y

in the circle, the values of x for -2< x< 2 each give 2 values of y.

hence this is not a function.
