Answer:
-11/30, -1/6, 2/5
Step-by-step explanation:
first, make the question in the same denominator
= 12/30, -5/30, -11/30
= -11/30, -5/30, 12/30
= -11/30, -1/6, 2/5
Answer:
s(t) = 2t^2-3t
19 = 2t^2-3t
2t^2-3t-19=0
t = [3 +- sqrt(9-4*2*-19)]/4
t = [3 +- sqrt(161)]/4
t = [3 +- 12.6886]/4
Positive answer:
t = [3+12.6886]/4
t = 3.9221 seconds
Step-by-step explanation:
Answer:
Student A Mean: 697/8=87.125
Student A Mean Absolute Deviation: 7.1563
Student B Mean: 756/9=84
Student B Mean Absolute Deviation: 7.3333
2x+18+1-1 works if that's all you want
Hello!
To find the probability of two events, you need to multiply the probability of all the events that make the compound event. In this case, we need to multiply the probability of selecting urn 1 and selecting a white marble from urn 1.
First, we have two urns, so we have a 1/2 chance of selecting urn 1.
Next, we have 16 total marbles in urn 1. If we have 5 white marbles, this gives us 5/16.
Finally, we multiply the probabilities. 1/2(5/16)=5/32.
Our final probability is 5/32, or about 16%.
I hope this helps!
