Answer:
r(A + B) = rA + rB,. (4). (r + s)A = rA + sA,. (5) r(sA)=(rs)A;. (6). A(BC)=(AB)C,.
Answer:
25/3
Step-by-step explanation:
3x:10=5:2
proportions are basically ratios, and ratios are basically fractions, so we can cross multiply
3x*2=10*5
6x=50
x=50/6
x=25/3
Using a 1-sample z-interval for the population proportion with confidence level 0.997, the sample probability is 0.69 with margin of error of 0.16, so between 0.69+0.16=0.85 of the population and 0.69-0.16=0.53 of the population prefers coffee. 84% and 54% are the correct answers.

Answer:
x^2 − x − 2 = 0
(x + 1)(x − 2) = 0
x + 1 = 0 ⇒ x1 = −1
x − 2 = 0 ⇒ x2 = 2
Min = (0.5, −2.25)
