7.2 connecting intercepts and linear factors answer key
1 answer:
An example of 7.2 connecting intercepts and linear factors is Graph y = x + 4 and y = x - 2 using a graphing calculator and then sketch the graphs on the grid.
<h3>What are linear factors?</h3>The linear factors of a polynomial are known to be the first-degree equations that are said to be the framework of more complex and higher-order polynomials.
The Graph of y = x + 4 and y = x - 2 with the sketch of its graphs on the grid is shown in the image attached.

Using conditional probability, it is found that there is a 0.052 = 5.2% probability that a randomly chosen U. S. President is left-handed and a democrat.
<h3>What is Conditional Probability?</h3>Conditional probability is the probability of one event happening, considering a previous event. The formula is:
In which
- P(B|A) is the probability of event B happening, given that A happened.
is the probability of both A and B happening.
- P(A) is the probability of A happening.
In this problem, the events are:
- Event A: President is left-handed.
- Event B: President is a democrat.
Researching the problem on the internet, it is found that:
- 40% of the presidents were left-handed, hence P(A) = 0.4.
- If a president is left-handed, there is a 13% chance that the president is a Democrat, hence P(B|A) = 0.13.
Then:
0.052 = 5.2% probability that a randomly chosen U. S. President is left-handed and a democrat.
