Answer:
a) Check graph
b)Closer to 0.5
c)Researcher 1 is right.
Step-by-step explanation:
a) Please check attached graph.
b) Please check second graph. It is shown that the value is 0.387 which is closer to 0.5.
c) Normal distributions are important in statistics and are often used in the natural and social sciences to represent real-valued random variables whose distributions are not known. The researcher 1 is right because there are numerous random variables are exist for this event and normal distribution function is the best function that gives less error for this numerous not-known random variables.
correctly (was that a question)
Answer:
The correct option is C
Step-by-step explanation:
From the question we are told that
The number of independent variables is
The number of observation is
Since n is are independent variables then their degree of freedom is 3
The denominator(i.e z) degrees of freedom is evaluated as
So for the numerator (n) the degree of freedom is Df(n) = 3
So for the denominator(i.e z) the degree of freedom is Df(z) = 43
Answer:
A
Step-by-step explanation:
A piece wise function involves two or more functions over specific intervals. The equations of the two lines are the following y=-2x+1 and y=-x+2. The line y=-x+2 continues to the right but has an open circle at the end so this point is not included. This means the interval is a greater than than sign but is not equal to. A is the answer.
We start off with 100 dollars. Which in this case Eliza deposits 25 every month.
What is average rate of change?
It is a measure of how much the function changed per unit, on average, over that interval
So this meaning that
25x + 100 would be are main focus here.
Replace x with 2 since we are finding the change of the 2nd account
25(2) + 100 = 150
Do the same problem but replace x with 10
25(10) + 100 = 350 dollars
So the average rate of change would be 25 dollars
