Seat belt use in a state was estimated at %, which means % of people use their seat belts. Suppose two independent drivers have been randomly selected. a. What is the probability that both of them are using a seatbelt? b. What is the probability that neither of them is using a seatbelt? c. What is the probability that at least one is using a seatbelt? a. The probability that both of them are using a seatbelt is 0.3. (Type an integer or a decimal. Do not round.)
Question
Seat belt use in a state was estimated at 89%,
which means 89 % of people use their seat belts. Suppose two independent drivers have been randomly selected.
a. What is the probability that both of them are using aseatbelt?
b. What is the probability that neither of them is using aseatbelt?
c. What is the probability that at least one is using aseatbelt?
The probability that both of them are using a seatbelt is ?
Answer:
a
[tex]P(B) = 0.7921[/tex]
b
[tex]P(B)' = 0.0121[/tex]
c
[tex]P(K) = 0.9879[/tex]
Step-by-step explanation:
From the question we are told that
The proportion of seat belt use is p = 0.89
The sample size n = 2
Generally the probability that both drivers are wearing seat belt is mathematically represented as
[tex]P(B) = (p)^n[/tex]
=> [tex]P(B) = (0.89 )^2[/tex]
=> [tex]P(B) = 0.7921[/tex]
Generally the probability that neither of the two drivers are wearing seat belt is
[tex]P(B)' = (1 - p)^2[/tex]
=> [tex]P(B)' = (1 - 0.89)^2[/tex]
=> [tex]P(B)' = 0.0121[/tex]
Generally the probability that at least one of the drivers is wearing a seat belt is
[tex]P(K) = 1 - P(B)'[/tex]
=> [tex]P(K) = 1 - 0.0121[/tex]
=> [tex]P(K) = 0.9879[/tex]
A map has a scale of 3 cm : 18 miles. If San Antonio and San Marcos are 54 miles apart, then they are how apart on the map?
Help please!!!!!!!!!!!!!!!!!!!!!!!!!!
Answer:add all of it on the calculator and you will get your awnser
Answer:
$1,475
Step-by-step explanation:
I'm pretty sure this is correct because if she gets an 18% tip, it would mean her payment is multiplied by 1.18. 1,250 times 1.8 equals $1,475.
Hope this helps! ^-^

Last night, he washed 4 plates in 2 minutes. Tonight, his grandparents are coming to dinner, and Rick will wash 6 plates.
If he washes plates at the same rate, how many minutes will it take Rick to wash the plates tonight?

id say about 3 minutes.
Step-by-step explanation:
if he washed 4 plates in 2 mins u would divide 4 by 2 and you'd get 2..aka half of a minute which is 30 seconds . so 30×6 is 180 which is 3 minutes
Answer:
3 minutes
Step-by-step explanation:
4 plates in 2 minutes
So, 1 plate in 1/2 minute
6 plates in 1/2 * 6 = 3 minutes

The value of a car decreases by about 15% in the first year. How much will a car be worth after one year if its initial value was 1000? 5000? 5020? X dollars?
Answer:
Results are below.
Step-by-step explanation:
Giving the following information:
Decrease in value= 15%
To calculate the value after one year, we need to use the following formula:
New value= current value/1.15
For $1,000:
New value= 1,000/1.15= $869.57
For $5,000:
New value= 5,000/1.15= $4,347.83
For $5,020:
New value= 5,020/1.15= $4,465.22
what is x/4 + 5 > 6=
