Fifty-nine percent of us adults have little confidence in their cars. you randomly select eight us adults. find the probability that the number of us adults who have little confidence in their cars is (1) exactly three and then find the probability that it is (2) more than 6.

 (1) 0.1332

(2) 0.0963

Step-by-step explanation:

Given : The proportion of US adults have little confidence in their cars:p = 0.59

Sample size : n= 8

Using Binomial probability formula :-

Then, the probability that the number of US adults who have little confidence in their cars is exactly three :-

The probability that the number of US adults who have little confidence in their cars is more than 6:-

step-by-step explanation:

if you want to solve percent error follow these steps.

1. subtract the accepted value from the experimental value.

2. take the absolute value of step 1.

3. divide that answer by the accepted value.

4. multiply that answer by 100 and add the % symbol to express the answer as a percentage.

if you want to solve percent of change just do this.

1. work out the difference (increase) between the two numbers you are comparing.

2. divide the increase by the original number and multiply the answer by 100. if your answer is a negative number then this is a percentage decrease.

c: y > - 1/6x + 1

step-by-step explanation:

dashed line - meaning this < or > also not equal

solid line - meaning this < or > also equal

your answer is c because y > means up & it's shaded up, but y < means down

hope this ! : )
