Answer: OPTION D.
Step-by-step explanation:
You need to analize the information given in the exercise.
Let be "x" the number of smaller pieces of string that can be cut from Allan's string.
According to the information given in the exercise, the total length of the piece of string that Allan has is the following:
Since Allan needs smaller pieces with and each one of them must have a length of 0.6 meters, then you can divide that total length of the entire piece by 0.6 meters, in order to find the value of "x".
Through this procedure, you get the following result:
Answer:
{x,y}={5,-3}

Answer:
Step-by-step explanation:
- We started at 1
- And it seems that index after index it multiplies by 3
- The formula for the geometric sequence defined implicitly is a(n) =a(1)r^(n-1)
Answer: x=12 and x=4 I hope this is correct sorry if it isn’t

Answer:
14.78% probability that a sample of 10 covers will contain exactly 2 defectives
Step-by-step explanation:
For each cover, there are only two possible outcomes. Either it is defective, or it not. The probability of a cover being defective is independent from other covers. So we use the binomial probability distribution to solve this question.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
In which is the number of different combinations of x objects from a set of n elements, given by the following formula.
And p is the probability of X happening.
If the fraction of defective covers produced on the USB Mouse Factory production line is known to be 8%, what is the probability that a sample of 10 covers will contain exactly 2 defectives?
This is when . So
14.78% probability that a sample of 10 covers will contain exactly 2 defectives
