There are 1,000 grams in a kilogram
To find the Chebyshev's inequality, P | Xn - E(X)| <= δ/4 >= 1 - (δ^2/25)/(δ^2/16) = 1 - (16/25) = 9/25 = 0.36
The answer in this question which is the probability that the average of the physicist's measurement is within δ/4 units of the actual specific gravity is at least 0.36%
The Distributive Property states: a(b+c) = ab+ac.
5(6+12) is the expression.
5•6+5•12 is the product of the Distributive Property.
30+60 is the product of multiplication.
Therefore, 30+60 is the correct answer.
• We just distributed the 5 to the 6 and 12 because the entire expression of 6+12 is being multiplied by the 5, hence there are parentheses.
