Answer:
x≥ 0
Step-by-step explanation:
7x+6 ≥ -(x-6)
Distribute the minus sign
7x+6 ≥ -x+6
Add x to each side
7x+x+6 ≥ -x+x+6
8x+6 ≥ 6
Subtract 6 from each side
8x+6-6 ≥ 6
8x≥ 0
Divide by 8
8x/8≥ 0/8
x≥ 0
The probability from 1.5 ≤ x ≤ 3 can be calculated by dividing the Area from x=1.5 to x=3 by the total Area of the distribution.
The given distribution is rectangular shaped, so its Area will be = Length x Width = 1 x 3 = 3 square units
From x = 1.5 to x = 3, the length is 1.5 and width is 1. So the area between these two intervals = 1.5 square units.
Thus, <span>P(1.5 ≤ X ≤ 3) = 1.5/3 = 0.5
