Answer:
x^2+5x+13=0
Step-by-step explanation:
x upper 2 and 5x
A=50 is the nth term for a to equal 100
Answer:
The P(x=45) is more that the P(x=20). Therefore x=45 successes is more likely to get.
Step-by-step explanation:
Given information: n=100 and p=1/3.
According to the binomial distribution, the probability of getting r success in n trials is

where, n is total trials, p is probability of success and q is probability of failure.
Total trials, n = 100
Probability of success, p = 
Probability of failure, q = 
The probability of 20 successes is


The probability of 45 successes is


The P(x=45) is more that the P(x=20). Therefore x=45 successes is more likely to get.
Answer:
D = 105
Step-by-step explanation:
Vertical angles are equal
D = E
D = 105
