B^2 - 4ac
(-9)^2 - 4 (2)(9)
= 81 - 72
=9 >0 yet it is a perfect square (3^2 =9)
So , it is 2 real and rational roots
(x-3) ( 2x-3) =0
x = 3 , x = 3/2
Answer:
Step-by-step explanation:
The sample space in a 3 times die roll =63=216.
Now, P(getting at least one 6)=1−P(getting NO 6).
Probability of getting no 6 in a single die roll
=56.
Thus probability of getting NO 6 in three die rolls
=56×56×56=125216.
Therefore, the probability of getting at least one 6
P=1−125216=91216.
Answer:
3,231 feet
Step-by-step explanation:
Find the difference between the two heights by subtracting them:
2933 - (-298)
2933 + 298
= 3231
So, the difference in altitude is 3,231 feet
