For every 144 light bulbs produced, 6 are defective. Find the number of defective light bulbs that could be expected out of 720.

2 answers:

7 0

You are going to get the rate of the detects.
6 detects ÷ 114 light bulbs = 1/19 detects per light bulb

If there are 720 light bulbs, then the number of detects will be
720 light bulbs * 1/19 detects per light bulb = 37. 89 ≈ 38 detects

Use the theoretical method to determine the probability of the following event. A randomly selected person has a birthday in Nov

MakcuM [25]

Answer:

There is an 8.22% probability that a randomly selected person has a birthday in November.

Step-by-step explanation:

The theoretical method to find the probability is the division of the number of desired outcomes by the number of total outcomes.

A randomly selected person has a birthday in November

There are 365 days in a year, so the number of total outcomes is 365.

There are 30 days in november, so the number of desired outcomes is 30.

So the probability is

$P = \frac{30}{365} = 0.0822$

There is an 8.22% probability that a randomly selected person has a birthday in November.

What is the product of the two binomial below

Svetach [21]

This is a difference of squares, meaning that when you multiply the binomials it would be the front term squared minus the last term squared.

The front term squared = (3A) squared = 9A squared
The last term squared = (4B) squared = 16B squared

Final Answer: D. 9A squared - 16B squared
