Which option below shows the graph of the function g(x) = (0.20)2 x ?
2 answers:
Answer:
Option 1
Step-by-step explanation:
Given : The function
To find : Which option below shows the graph of the given function ?
Solution :
We know that,
The y-intercept of a function is the value of y when the value of x is equal to zero.
Substitute x=0 in the given function,
This shows that graph is passing through the point (0,0.20).
In the following options on graph 1 the point passes through the point.
Therefore, Option 1 is correct.

Answer:
50% of students have a GPA higher than 3.1.
Step-by-step explanation:
We are given that the mean GPA of students in a neighboring school is 3.1 with a standard deviation of 0.3.
Assuming that the data follows normal distribution.
<u><em>Let X = GPA of students in a neighboring school</em></u>
So, X ~ Normal()
The z score probability distribution for normal distribution is given by;
Z = ~ N(0,1)
where, = population mean GPA = 3.1
= standard deviation = 0.3
Now, the probability that the students have a GPA higher than 3.1 is given by = P(X > 3.1)
P(X > 3.1) = P( >
) = P(Z > 0) = 0.50
<em>The above probability is calculated by looking at the value of x = 0 in the z table which has an area of 0.50.</em>
Therefore, 50% of students have a GPA higher than 3.1.
