Although cities encourage carpooling to reduce traffic congestion, most vehicles carry only one person. For example, 64% of vehicles on the roads are occupied by just the driver. (Round your answers to four decimal places.)A) If you choose 10 vehicles at random, what is the probability that more than half (that is, 6 or more) carry just one person?
B) If you choose 92 vehicles at random, what is the probability that more than half (that is, 47 or more) carry just one person? (Use the normal approximation.)

a) 0.7291 is the probability that more than half out of 10 vehicles carry just 1 person.

b) 0.996 is the probability that more than half of the vehicles  carry just one person.    

Step-by-step explanation:

We are given the following information:

A) Binomial distribution

We treat vehicle on road with one passenger as a success.

P(success) = 64% = 0.64

Then the number of vehicles follows a binomial distribution, where

where n is the total number of observations, x is the number of success, p is the probability of success.

Now, we are given n = 10

We have to evaluate:

0.7291 is the probability that more than half out of 10 vehicles carry just 1 person.

B) By normal approximation

Sample size, n = 92

p = 0.64

We have to evaluate the probability that more than 47 cars carry just one person.

After continuity correction, we will evaluate

Calculation the value from standard normal z table, we have,  

0.996 is the probability that more than half out of 92 vehicles carry just one person.

step-by-step explanation:

when a number is between two straight lines it means the absolute value.

to find absolute value you need to know how many numbers is that number away from 0.

when finding absolute value the number will always come out positive

so absolute value of -3 is 3

absolute value of 3/2 is 3/2

absolute value of -2 is 2

absolute value of 3.5 is 3.5

absolute value of -1 is 1

now put these numbers in order:

a)   |-1|, |3/2|, |-2|, |-3|, |3.5|

dont't really have enough info here but its likely

sss for the three sides being congruent ( its stands for side side side)

or

sas   for side angle side.   so a side is congruent and and angle and a side
