Solution:- Let f and g be the functions such that
can be used to form a function which maps x in X to
in Z.
If z is a function of y, and y is a function of x, then z is a function of x. (transitive property)
Hence the composite function is given by
, defined by
for x in X.
Now , for the function g(x) into the function for f(x), we have to work from the inside out by substituting the expression. So by this way composition of function related to order of operations.
Sort the data into this order:
2.6, 3, 4.9, 5, 5, 6, 6, 7.9, 8, 8.2
^
there are 10 data points in total, therefore the Interquartile Range = between the 5th and the 6th numbers, which are 5 and 6
(5+6)/2= 5.5
29.98+ 6.44 = 36.42 (cost with out the discount)
36.42/3 = 12.14
Answer-
12.14
Answer:
b
Step-by-step explanation:
The area of a square = s² ← s is the length of the side, hence
s² = 800 ( take the square root of both sides )
s =
≈ 28.28
28.28 is between 28 and 29 → b
