The table gives the mean and standard deviation of four data distributions.Mean Standard Deviation
Distribution 1 22 0.2
Distribution 2 21 0.8
Distribution 3 19 1.2
Distribution 4 20 3.2
which Distribution has the greatest spread.? help please !
Answers
The distribution 4 has the greatest spread because the value of the standard deviation is 3.2
What is the standard deviation?
It is defined as the measure of data disbursement, It gives an idea about how much is the data spread out.
As we know, the standard deviation will give idea about the spread of the data.
As we can see in the distribution 4
The standard deviation = 3.2
And 3.2 is the bigger than all other distribution.
Thus, the distribution 4 has the greatest spread because the value of the standard deviation is 3.2

b.Yes: if the vertex is at (m,n), then the domain is all reals and the range is y ≤ n.
c.No: we would need to know if the vertex is a minimum or a maximum.

C)( 0.25, 5.875)
D)( 0.25, 6)

The correct answers are:
C) No: we would need to know if the vertex is a minimum or a maximum; and
C)( 0.25, 5.875).
Explanation:
The domain of any quadratic function is all real numbers.
The range, however, would depend on whether the quadratic was open upward or downward. If the vertex is a maximum, then the quadratic opens down and the range is all values of y less than or equal to the y-coordinate of the vertex.
If the vertex is a minimum, then the quadratic opens up and the range is all values of y greater than or equal to the y-coordinate of the vertex.
There is no way to identify from the coordinates of the vertex whether it is a maximum or a minimum, so we cannot tell what the range is.
The graph of the quadratic function is shown in the attachment. Tracing it, the vertex is at approximately (0.25, 0.5875).

Answer: 0.48
Step-by-step explanation:
Given : The probability that a customer will order a hamburger P(H)= 0.60.
The probability that a customer will order french fries P(F)= 0.50.
The restaurant has also determined that if a customer orders a hamburger, the probability the customer will also order fries : P(F|H)= 0.80.
Using conditional probability formula , for any event A (first event) and B (second event), we have:-
Similarly, the probability that the order will include a hamburger and fries :-
Hence, the probability that the order will include a hamburger and fries=0.48
