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.

h

step-by-step explanation:

whatever you can spend with $11.53 or under.

step-by-step explanation:

20 - 8.47 = 11.53. take away the money he used for lunch from the starting amount of 20.

(f - g)(x) = 5x^3 - 3

step-by-step explanation:

rearrange these functions vertically, with like terms in separate columns:

f(x) = 5x^3 - 2

g(x) =         +1

now subtract, column by column:

(f - g)(x) = 5x^3 - 3

34.5 cm

step-by-step explanation:

generally for a circular segment of angle, θ° and radius r

arc length

= (θ/360) x circumference

= (θ/360) x 2πr

in our case, θ = 60°, π=3.142 and r = 33 cm

substitute into above formula

arc length

= (60/360) x 2(3.142)( 33) = 34.5 cm
