Answer: 7.73 x 2 = 15.46
Step-by-step explanation: 7.73x
42)
prime numbers are 41, 43, 47
answer
F. 3
35)
36 colored
faction 36/60 = 18/30 = 6/10 = 3/5
faction not equivalent to is 8/20
answer is C. 8/20
11)
answer is D. 18.21
cause 18.21 > 17.06 and 18.21 < 18.307
Answer:
For g (2) = 3x -2 find the value of x
The value of x is 2
for which g(x) = 10?
10 = 3x -2
10 +2 = 3x
12 = 3x
x = 12/3
x = 4
The probability that you will guess the first answer correctly = 1/2 = 0.5
The probability that you will guess the second answer correctly = 1/2 = 0.5
The probability that you will guess the third answer correctly = 1/2 = 0.5
The probability that you will guess all three answers correctly is
(0.5) x (0.5) x (0.5) = 0.125 = 12.5% .

Here are all the ways your answer sheet could wind up:
(R = a right answer. W = a wrong answer.)

Number of possible ways to score 0 right out of 3 questions: 1 way
Number of possible ways to score 1 right out of 3 questions: 3 ways
Number of possible ways to score 2 right out of 3 questions: 3 ways
Number of possible ways to score 3 right out of 3 questions: 1 way
Statistically, if your answers are all pure guesses,
then on the average, the score you expect is
(0 + 33-1/3 + 33-1/3 + 33-1/3 + 66-2/3 + 66-2/3 + 66-2/3 + 100) / 8
= 400 / 8
= 50% .
If you're happy with that score, great !
Go to the movies the night before the test,
and start guessing.
