Answer:
B. x < -8 or x > 8
Step-by-step explanation:
You can use process of elimination to solve this problem by going through every solution and testing them out, but let's jump right to B.
Process:
You know that since the inequality states that x^2 has to be greater than 64, x has to be more than 8, or less than -8.
This is because 8^2 = 64, and -8^2 = 64, and the inequality requires the answer to be more than 64.
Looking at B., you can see that if x is < -8, the square of, for example, -9, would be 81. This is greater than 64, so this works!
Now, B. also has an alternative. The 'or' is a major clue to which is the correct answer, since the square root of any number can be positive or negative. (-8^2 = 8^2)
The 'or' states that x must be greater than 8. So, for example, if we take the square of 10, we get 100, and that is also greater than 64.
We've proven that this solution is accurate for both parts, so it is definitely the one we want!
Hope this helps!
Answer:
0.097 is the probability that the entire batch will be rejected
Step-by-step explanation:
The total number of CDs = 6500
Number of defective CDs = 110
Number of good CDs = 6500-110 = 6390
Out of this batch, 6 are randomly selected, then the probability that the entire batch is rejected is
1 – [probability of accepting the entire batch]
1 – [6390/6500 * 6389/6499*6388/6498*6387/6497*6386/6496*6385/6495]
= 0.097
Answer:
65
Step-by-step explanation:
1/2 which is half of total is green
1/4 is bad and the remaining apples are red
1/2 of 260 = 130 green apples
1/4 of 260 = 65 bad apples
the remaining is 1/4 which is equal to 65 are red apples
