Answer:
The answer is option 1.
Step-by-step explanation:
In order to find the equation, you have to apply Discriminant Law, D = b² - 4ac. When D < 0, the equation has no real roots (no x-intercept). When D = 0, it has 2 and equal roots (1 x-intercept). When D > 0, it has 2 distinct roots (2 x-intercept).
Option 1,




Option 2,



Option 3,




Option 4,




As you look at the graph, the curve does not meet x-axis so the discriminant must be less than 0.

<span><span>HeadsTails</span><span>3822</span></span>
<span>Using Polly's simulation, what is the probability of pulling an orange ribbon and the coin landing on tails?</span>
Answer:
14.4
Step-by-step explanation:
Divide 18 miles by 5 hours to tell us how many miles she can do in 1 hour.
Multiply the answer by 4 to tell us how many miles in 4 hours.
(18/5) * 4 = 14.4 Miles
For this data set:
mean = 1.75
standard dev. = 5.6252 or 5.63
