3/10 is the probability of them losing.
To take a root of a fraction, take the root of the numerator and denominator separately
Write the number in exponential form with a base of 2 to the second power
Write the number in exponential form with a base of 3 to the third power
Reduce the index of the radical and exponent with2
Reduce the index of the radical and exponent with 2
Then it’s gonna be 2/3 2over3
-3 2/3
Reduce the numbers with greatest common divisor 3
Then the answer will be -2
So its in the pic i hope it helps it is correct because i am in highschool i like to help people
A1 = first term
a1 = 15
---------------------------------------------
d = common difference
d = (second term) - (first term)
d = a2 - a1
d = 9-12
d = -3
The negative common difference indicates that the terms are decreasing
Each time we subtract 3, or add -3, to get the next term.
----------------------------------------------
nth term of arithmetic sequence
an = a1 + d(n-1)
an = 15 + (-3)(n-1)
an = 15- 3n + 3
an = 18 - 3n
Answer is choice D
