So the equation to find the discriminant is 
, with a = x^2 coefficient, b = x coefficient, and c = constant. Using that formula, our equation is 
- Firstly, solve the exponent and multiplications:
- Next, do the subtraction, and your discriminant is -23.
Now because the discriminant is <u>less than zero</u>, there are <u>no real solutions.</u>
Answer:3.14
Step-by-step explanation:Pi goes inf
Answer:
x = 7
Step-by-step explanation:
all we know is that she had 1 brownie at the end, in the end she gave half her brownie to tyler, so add one who will get 1 1/2, before that she split her brownies between her friends, so multiply 1 1/2 by 2 and you will get 3, before that she gave 1/2 a brownie to Kiran, so we would add 1/2 to 3 and get 3 1/2, before that she first split it in half for a her friends, so at last, multiply 3 1/2 by 2 and you will geet 7 as your final answer.
Conditional probability:
P ( B \ A ) = P ( A and B ) / P ( A )
Probability of an event B given by that A has already occurred.
P ( A and B ) = 0.051
P ( A ) = 0.32
P ( B \ A ) = 0.051 / 0.32 = 0.159375 ≈ 0.159
Answer:
B ) 0.159
