The probability of getting 3 or more who were involved in a car accident last year is 0.126.
Given 9% of the drivers were involved in a car accident last year.
We have to find the probability of getting 3 or more who were involved in a car accident last year if 14 were selected randomly.
We have to use binomial theorem which is as under:
n
where p is the probability an r is the number of trials.
Probability that 3 or more involved in a car accident last year if 14 are randomly selected=1-[P(X=0)+P(X=1)+P(X=2)]
=1-{}
=1-{1*0.2670+14!/13!*0.9*0.29+14!/2!12!*0.0081*0.2358}
=1-{0.2670+0.3654+0.2358}
=1-0.8682
=0.1318
Among the options given the nearest is 0.126.
Hence the probability that 3 or more are involved in the accident is 0.126.

Answer:
y = 2 - 1/2x
Step-by-step explanation:
So we are given the equation 3x + 6y = 12 and are ask to find y.
To find y you must isolate it first.
3x + 6y = 12
(Subtract 3x to isolate the y term)
6y = 12 - 3x
(Divide both sides by 6 to isolate the variable)
y = 2 - 3/6x
(Simplify)
y = 2 - 1/2x
And that is your answer since there is a second variable.
Answer:
7.4 · 10^4
Step-by-step explanation:
For scientific notation, multiplication is pretty simple.
In this case, you would only multiply the "regular" number by 2.
(3.7 · 2) · 10^4
= 7.4 · 10^4
However, if it were asking about multiplying the number with something else in scientific notation, in addition to what we did above, you'd add together the exponents.

Answer:
E. 36
Step-by-step explanation:
You have to do a² + b² = c²
Plug in
15² + b² = 39²
225 + b² = 1521 (subtract 225 on both sides)
√b² = √1296 (square root on both sides)
b = 36
