Complete question :
The spinner shown is spun once. Determine the probability of each event. Express each answer as a fraction, a decimal, and a percent. P(C)
Answer:
1 / 8; 0.125 ; 12.5%
Step-by-step explanation:
From the spinner :
The number of partitions or faces on the spinner is 8 ;
The number of occurences of c on the spinner is 1
The probability of obtaining c written as P(c) :
Probability = required outcome = number of c on spinner / total possible outcomes, total number of faces in spinner = 8
P(c) = 1 / 8
As decimal :
1/8 = 0.125
As a percentage :
0.125 * 100% = 12.5%

Answer:
a(10) = 3^9 = 19683
Step-by-step explanation:
In this sequence each new term is equal to 3 times the previous term. Thus, 3 is the common ratio. The first term is 1.
The general formula for the nth term of a geometric sequence i
a(n) = a(1)*r^(n -1), where r is the common ratio.
Here, a(n) = 1*3^(n - 1), and so
the 10th term is
a(10) = 1*3^(10 - 1), or
a(10) = 3^9 = 19683
Answer: B) 0 real roots
---------------------------------------
The general rule is...
if D > 0, then you have two different real roots (see note below)
If D = 0, then you have exactly one real root
If D < 0, then you have no real roots (the two roots are imaginary/complex)
where D is the discriminant found by the formula
D = b^2 - 4ac
Note: If D is also a perfect square, then the two real roots are also rational. This assuming that a,b,c are rational.
