Based on the graph below, what is the total number of solutions to the equation f(x) = g(x)?
2 answers:
<h2>Answer:</h2>
The total number of solutions to the equation f(x) = g(x) is:
Tow solution (2 solution)
<h2>Step-by-step explanation:</h2>We are given two functions f(x) and g(x).
The solution to the equation:
are the x-values of the point of intersection of the graphs of the two function.
By looking at the graph we observe that the graph of two function intersects at two points (-3,7.5) and (1,0).
Hence, the number of solutions to the equation f(x)=g(x) is: Two solutions.

Step-by-step explanation:
Given that X the time to complete a standardized exam in the BYU-Idaho Testing Center is approximately normal with a mean of 70 minutes and a standard deviation of 10 minutes.
We have 68 rule as 2/3 of total would lie within 1 std deviation, and 95 rule as nearly 95% lie within 2 std deviations from the mean.
We have std deviation = 10
Hence 2 std deviations from the mean
= Mean ±2 std deviations
=±20
=
Below 50, 0.25 or 2.5% would complete the exam.
