I’m just guessing but since 13/4=3.25 that means that the triangle dialated by 3.25 so you multiply 8 by 3.25 and X might be 26
The answer is: 6/5
Here is why:
3x - 5y = -3
3(1) - 5y = -3
3 - 5y = -3
3 - 5(6/5) = -3
-3 = -3
Answer:
The probability of the pointer landing on yellow is equal to the probability of the pointer landing on red
The mean : 2.5 million
S D = 0.6 million
2.5 - 2 · 0.6 = 2.5 - 1.2 = 1.3 million
2.5 + 2 · 0.6 = 2.5 + 1.2 = 3.7 million
Chebyshev theorem : at least 3/4 of the data lie within 2 standard deviations of the mean.
