Answer:
a. P(AnB)
b. P(B|A)
c. 
d. P(A or B)
e. 
Step-by-step explanation:
Since A= driver is under 25 years old (1)
B = driver has received a speeding ticket (2)
a.The probability the driver is under 25 years old and has recieved a speeding ticket.
this simple means the intersection of both set, which can be written as
P(AnB)
b. The probability a driver who is under 25 years old has received a speeding ticket.
This is a conditional probability, probability that B will occur given that A as occur.
P(B|A)
c. the probability a driver who has received a speeding ticket is 25 years or older.
d. The probability the driver is under 25 years old or has received a speeding ticket.
P(A or B)
e. The probability the driver is under 25 years old or has not received a speeding ticket.
Answer:
answer is 5
Step-by-step explanation:
I used a calculator
1)
The distance between points A and B is;
,
and if you wanted to you could measure out the legs of that hypotenuse using the slope between A and B, but I'm going to show you the easier way;
Δx = 4
Δy = -20
So from the midpoint, add 4 to the x-value and subract 20 from the y-value.
{(5+4),(-8-20)}
(9,-28) is the endpoint.
2)
Do the same thing as I did above;
So
is the distance.
Sorry for the delay, life delayed me a ton ,:D
Answer:
B. The fundamental theorem of algebra tells you that the equation will have two complex roots since the degree of the polynomial is 2. The roots are x=3±i√11/2 .
Step-by-step explanation:
We know that,
Fundamental theorem of algebra states that ' a polynomial of degree n will have n number of roots'.
Since, the polynomial 
has degree 2, so it will have 2 roots.
We know that the polynomial 
has roots given by 
.
So, the roots of polynomial 
will be,
i.e. 
i.e. 
i.e. 
i.e. 
Hence, the roots are given by 
So, option B is correct.
