Answer:
what exactly do you need done?
A 95% confidence interval for the proportion of non-fatal accidents involving a distracted driver using some kind of electronic device is 62.5%<x<71.61%
The 95% confidence interval for the proportion is expressed according to the formula;
p is the proportion = 268/400 = 0.67
z is the 95% z-score = 1.96
n is the sample space = 400
Substitute the given parameters into the formula to have:
Hence a 95% confidence interval for the proportion of non-fatal accidents involving a distracted driver using some kind of electronic device is 62.5%<x<71.61%

Answer:
the answer is 72,792
Step-by-step explanation:
just subtract 72,792-72
Answer:
a)
b) SSA does not constitute a proof. You need another fact.
Step-by-step explanation:
You should actually show congruency first
Angles opposite = sides are themselves equal.
<C = 50o
<J = 50o
But there is nothing that says x is 1/2 of <JAC
So it's unsolvable
Part B also has the same conclusion.
The expected value of the game is $2.00.
To Find: The fair price to pay to play the game of rolling a colored die with three red sides, two green sides, and one blue side
Now the question arises how to find the Fair Price
We are told that in the game of rolling the colored die;
A roll of a red loses.
A roll of blue pays 5.00 and A roll of green pays 2.00.
Now, the best game to get the fairest price is to play; RRRGGB i.e (RED, RED, RED, GREEN, GREEN,BLUE)
Fair price = 2(3/6) + 6(1/6) + 0(2/6)
Fair price = $2
