The numbers less than 5 or even are {1, 2, 3, 4, 6}. This is 5 of the 6 possible numbers.
The probability of getting one of these on a single roll of a single die is 5/6.
If a, b, c is an arithmetic sequence then a + c = 2b
a = 5, b = 9, c = 15
subtitute
a + c = 5 + 15 = 20
2b = 2 · 9 = 18
20 ≠ 18
Answer: The sequence 5, 9, 15 is not an arithmetic sequence.
Answer:
discriminant
Step-by-step explanation:
Discriminant is the expression under the radical in a quadratic equation formula that indicates the nature of the solutions real or complex, rational or irrational , single or double root in other words
A discriminant can be said to be used to indicate the nature of the result that a quadratic equation when solved will yield and this can be : rational or irrational , complex or real, single or double roots. and it also indicates by how many it would be
Answer:
3^81 is bigger
Step-by-step explanation:
3^81=4.43426488e38
9^27=5.8149737e25
X would equal 4
set AB=AC
18=3x+6
minus 6 on both sides
12=3x
divide both sides by 3
x=4
