Answer:
0.7755
Step-by-step explanation:
If 120 CDs are defective, the number of non-defective CDs in the batch is:

In order for the batch to be accepted, all of the 4 CDs in the sample must not be defective, the probability of that happening is:

The probability that the entire batch will be accepted is 0.7755.
A complement adds up to 90 degrees, so we just need to halve that, to get 45 degrees.

Inequalities are the greater than, greater than or equal to, less than, or less than or equal to—between two numbers or algebraic expressions.
Answer:
x = 11
Step-by-step explanation:
Lines are parallel. 5x + 10 and 10x + 5 are supplements of each other.
Move 5x+ 10 to the corresponding position on the figure. It will be next to 10x + 5 and form a linear pair with 10x + 5. A linear pair form a straight angle or two supplementary angles. Supplementary angles = 180°
Therefore 5x +10 + 10x + 5 = 180°
15x + 15 = 180°
15x = 180 - 15
15x = 165
x = 11
