19 + 16 + 24 + 12 + 16 + 21 + 18 = 126
126/7 = 18
18 is the mean of the data set.
12-2+22/8 (=12.75 so the option of doing nothing isn't right)
12-(2+2)2/8 (=11 so that option is gone)
(12-2)+22/8 (=12.75 so that option is gone as well)
12-2+(22/8) (=12.75 So that's gone as well)

Answer:
10.6 cones
Step-by-step explanation:
Given data
h= 4cm
d= 1.5cm
r= d/2= 0.75cm
The expression for the volume of a cone is
V= 1/3πr^2h
substitute
V= 1/3*3.142*(0.75)^2*4
V= 1/3*3.142*2.25
V=1/3*7.0695
V= 2.3565cm^3
Since the volume of 1 cone is 2.4cm^3
She can fill
=25/2.3565
=10.6 cones
About 10.6 cones
