Select the correct answer from each drop-down menu.
an art curator records statistics about three new exhibits at her art museum. the mean age of the artifacts and the standard deviation, sd, for each exhibit are recorded in the table below.
exhibit a exhibit b exhibit c
mean = 42
sd = 4.9 mean = 96
sd = 3.7 mean = 234
sd = 6.1
use the information in the table to complete the following statement.
exhibit shows the least consistency in the age of the artifacts in the exhibit, because its is the

the correct answer is b. negative exponential growth.

step-by-step explanation:

you can tell it's an exponential function because it decreases rapidly then levels out and never touches the x-axis.

it is negative because the y-axis decreases as the x-axis increases.

therefore it is a negative exponential growth graph.

hope i !

hi how are you doing today? if you ever need just tell me

step-by-step explanation:

step-by-step explanation: it is d

an = 22 + (n-1) *6

110 seats

step-by-step explanation:

an=a1+(n-1)(d)

a1 = 22   this is the first item in the sequence

d =6   this is how the sequence goes up

a)   an = 22 + (n-1) *6

b) a12 = 22 + (12-1) *6

    a12 = 22+11*6

  a12 = 22 +88

  a12 = 110
