Chebyshev's theorem says that the probability that a random variable differs from its mean by some multiple of the standard deviation is bounded below as

Solve for <em>k</em> :

Then the theorem says

which is to say that 88.9% of the data will fall in the interval

or roughly corresponding to scores between 7.076 and 7.924.
6/7 already reduced to the lowest terms;
the numerator and the denominator have no common prime factors:
6 = 2 × 3;
7 is a prime number;
98/100 = (2 × 72)/(22 × 52) = ((2 × 72) ÷ 2)/((22 × 52) ÷ 2) = 49/50;
Answer:
x = 3
y = 2
Step-by-step explanation:
0.0850284. Move the decimal back two spaces from original spot. You would move forward if it was a positive exponent.
Answer:
A : quadratic trinomial
Step-by-step explanation:
Given
(3x² - 11x - 4) - (2x² - x - 6)
Distribute both parenthesis, noting the second is distributed by - 1
= 3x² - 11x - 4 - 2x² + x + 6 ← collect like terms
= x² - 10x + 2 ← this is a quadratic with 3 terms, thus quadratic trinomial → A
