A spinner is to be used during a probability experiment. The spinner is separated into all congruent sections of which 8 section

s are orange, 4 sections are yellow, and 2 sections are green. What is the probability written in simplest form that the spinner will NOT stop on a green section during the first spin?

Not green...means orange or yellow

Total sections=8+4+2=14, orange and yellow sections=8+4=12

P(y or o)=12/14

P=6/7  (about 85.7%)

Please help me understand and explain it to me please.<br><br>Recursive Sequence Function ​
DedPeter [7]

A recursive sequence is a sequence of numbers whose values are determined by the numbers that come before them in the sequence.

We’re given a sequence whose (n + 1)-th term f(n + 1) depends on the value of the n-th term f(n), specified by the recursive rule

f(n + 1) = -4 f(n) + 3

We’re also given the 1st term in the sequence, f(1) = 1. Using this value and the recursive rule, we can find the next term f(2). (Just replace n with 1.)

f(1 + 1) = -4 f(1) + 3

f(2) = -4 • 1 + 3

f(2) = -1

We do the same thing to find the next term f(3) :

f(2 + 1) = -4 f(2) + 3

f(3) = -4 • (-1) + 3

f(3) = 7

One more time to find the next term f(4) :

f(3 + 1) = -4 f(3) + 3

f(4) = -4 • 7 + 3

f(4) = -25

What is the solution to the system of equations? Use the substitution method.
aleksandrvk [35]
{ y = 3 x - 4
  9x -3y = 14

Subsititute y = 3x-4 :

[ 9 x - 3 ( 3 x-14 )=14]

Refine:

9 x  - 3 ( 3 x - 4 ) = 14

- 2 = 0

is false , therefore the system of equations has no solution

Answer A

What is 4.2 kilometers in meters
vovikov84 [41]
THE ANSWER IS 42,000.

TO GET THIS WE KNOW THAT 1 KILOMETERS IS 10,000. 

SO YOU TAKE 4.2 AND MULTIPLY IT BY 10,000. THAT EQUALS 42,000.

Answer:

137

Step-by-step explanation:

sum of angle in a circle = 360°

105 + 118 + x = 360

223 + x = 360

x = 360 - 223

x = 137
