The answer is b its easy i had this one
Answer:
d. Two complex solutions
Step-by-step explanation:
We have been given a trinomial
and we are supposed to predict the type of solutions of our given trinomial.
We will use discriminant formula to solve for our given problem.
, where,
,
,

Conclusion from the result of Discriminant are:
Upon substituting our given values in above formula we will get,


Since our discriminant is less than zero, therefore, out given trinomial will have two complex solutions and option d is the correct choice.
Answer:
Slope? If so it is 13/-6
Step-by-step explanation:
Use y1-y2/x1-x2
Answer:
0.815
Step-by-step explanation:
First, find the z-scores.
z = (x − μ) / σ
z₁ = (8 − 10) / 1
z₁ = -2
z₂ = (11 − 10) / 1
z₂ = 1
P(-2 < Z < 1) = P(Z < 1) − P(Z < -2)
Use a chart, calculator, or the empirical rule to find the probability.
Using the empirical rule:
P(-2 < Z < 1) = 0.84 − 0.025
P(-2 < Z < 1) = 0.815
Using a chart:
P(-2 < Z < 1) = 0.8413 − 0.0228
P(-2 < Z < 1) = 0.8185
