54% of u. s. adults have very little confidence in newspapers. you randomly select 10 u. s. adults. find the probability that the number of u. s. adults who have very little confidence in newspapers is (a) exactly five, (b) at least six, and (c) less than four.

This question is based on the probability. Therefore, the required probabilities  are :  (a) ,  (b)  and (c) .

Given:

54% of U.S. adults have very little confidence in newspapers. You randomly select 10 U.S. adults.

We have to find the probability that the number of U.S. adults who have very little confidence in newspapers is (a) exactly five, (b) at least six, and (c) less than four.

According to the question,

In this we have to calculate the probability using the binomial probability formula,

Where, p is the probability of obtaining a "favorable outcome ", x is the number of desired "favorable outcome " and n is the number of times the experiment is repeated. In this case n = 10 and p = 0.54.

(a) exactly five  

x=5, n= 10, p = 0.54

P(X=5) = 0.238

(b) at least six

(c) less than four

Therefore, the answers are :  (a) ,  (b)

and (c) .

Step-by-step explanation:

In this case we can calculate the probability using the binomial probability formula

Where p is the probability of obtaining a "favorable outcome " x is the number of desired "favorable outcome " and n is the number of times the experiment is repeated. In this case n = 10 and p = 0.54.

(a) exactly five

This is:

So:

(b) at least six

This is:

(c) less than four

This is:

answer: 25.4 units

step-by-step explanation: radius = 12.7 units

diameter = twice the radius

diameter = 12.7 x 2

= 25.4

the one that has a slope of 1/2 and is positive.
