In order to use a Normal model to represent the distribution of a data set, which of the following statements must be true?
OA.
The distribution of the data set must be bimodal and clearly non-symmetric.
OB.
The distribution of the data set must be unimodal and clearly non-symmetric.
C.
The distribution of the data set must be bimodal and roughly symmetric.
D.
The distribution of the data set must be unimodal and roughly symmetric.

d is the correct answer

step-by-step explanation:

x= 8 because 3x = 3 * 8, and 3*8 = 24

(1, –1), (16, –4), (36, –6)

step-by-step explanation:

given that the function is

this can also be written as

we have to graph this function and check which list of points lie on the graph

see attachment for graph:

we find that the points lying are (1,-1) (16,-4) and (36,-6)

since square root is there we find that x can only be posiitve but y can be since square root both positive and negative.

answe: it will take 4.5 hours for naomi and clair to paint an equal number of square feet

hope i
