Answer: B. 0 and D. 3
Step-by-step explanation:
Here the given function is,
For finding the solution of this system of equation,
First we will plot the function on the graph,
Graph of function f(x),
x-intercept and y-intercept are (1.286,0) and (0,-3) respectively,
Also, it is a straight line,
Hence, we can plot this line on the graph,
Graph of function g(x),
Function g(x) is an exponential function having x-intercept and y -intercept, (2,0) and (0,-3) respectively.
Also, the end behavior is,
As ,
As ,
Hence, we can plot the graph of g(x),
By plotting the graph,
We found that the intersection of the function f(x) and g(x) are (0,-3) and (3,4).
Hence, the solution of the system is the x-coordinates of the intersection points that are 0 or 3.
⇒ Option B and C is the correct options.
Answer:
We know that the total area under the normal curve is 100%. According to the empirical rule of Normal distribution:
Approximately, 68% of data lies within standard deviations of mean.
Approximately, 95% of data lies within standard deviations of mean.
Approximately, 99.7% of data lies with standard deviations of mean,
Therefore, in a normal curve, roughly 95% of all cases fall within plus or minus two standard deviations.
