The third graph or bottom left graph represents
Step-by-step explanation:
Step 1:
To determine which of the given graphs represents the equation , we substitute some values in the place of x.
When
Anything with an exponent of 0 will equal 1.
So the graphs on the right side cannot be the answers.
Step 2:
Now we substitute another value to determine which graph represents
When
The value of f(x) when is lesser than the value of f(x) when
So the third graph or bottom left graph represents
Solution: We are given:
Using the empirical rule, we have:
covers 68% of data.
Also the percentage of values below mean = Percentage of values above mean = 50%
Now, let's find the z score for x=20
Therefore, the percentage of values greater than 1 standard deviation above mean
Expected number of students = 16% of 100 = 16
