2/5=6/15
1/3=5/15
11/15
yes. that would be the last one possible.
(a)36 = 6
(b)81 = 9
(c)256 = 16
(d)196 = 14
Mean is

b. For X=90,
and for X=110,
. Then
(the decimal value is taken from the Standard Normal Distribution Table).
Answer:
6cm
Step-by-step explanation:
Given data
Width= 4.6cm
Length= 9cm
Volume= 82.8cm^3
The expression for the volume is given as
V= lwh/3
82.8= 9*4.6*h/3
cross multiply
82.8*3= 9*4.6*h
248.4= 41.4h
h= 248.4/41.4
h= 6cm
In step two he flipped the fraction back to how it was originally but he was supposed to leave it improper in order to multiply
