Answer:
A
Step-by-step explanation:
Given
y = 2x² - 3x + 1
To find the zeros let y = 0, that is
2x² - 3x + 1 = 0
Consider the factors of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term.
product = 2 × 1 = 2 and sum = - 3
The factors are - 2 and - 1
Use these factors to split the x- term
2x² - 2x - x + 1 = 0 ( factor the first/second and third/fourth terms )
2x(x - 1) - 1(x - 1) = 0 ← factor out (x - 1) from each term
(x - 1)(2x - 1) = 0
Equate each factor to zero and solve for x
2x - 1 = 0 ⇒ 2x = 1 ⇒ x = 
x - 1 = 0 ⇒ x = 1
5/15 is the answer simplified is 1/3
Answer:
C
Step-by-step explanation:
2x - 1 = 7
2*4=8
8-1=7
Using the binomial distribution, it is found that the probabilities are:
<h3>What is the binomial distribution formula?</h3>
The formula is:
The parameters are:
- x is the number of successes.
- n is the number of trials.
- p is the probability of a success on a single trial.
Exercise 1:
The parameters are:
n = 15, p = 0.4, x = 4.
Then:
Exercise 2:
The parameters are:
n = 12, p = 0.2, x = 2.
Then:
Exercise 3:
The parameters are:
n = 20, p = 0.05.
The probability is:
Using the binomial formula for each value and adding them:
