Answer:
A. 4
Step-by-step explanation:
First rearrange the temperatures from low to high
60, 65, 68, 69, 69, 70, 70, 70, 71, 71, 73, 74, 75, 77
There are 14 data,
Q1 = 4th data = 69
Q3 = 11th data = 73
Interquartile range = Q3 - Q1 = 73 - 69 = 4
Answer:
The calculation of Mrs. Hernanadez will affect by 1.375 inches lesser.
Step-by-step explanation:
Given:
Length of the Kitchen shelf = 26 3/8 inches
Width of the Kitchen Shelf = 15 1/2 inches
Incorrect measurement of the length of the kitchen shelf = 25 inches
Solution:
The Actual length of the kitchen shelf is 
But she measured as 25 inches
So the error in the measurement will be
=>Correct length of the shelf - Incorrect length of the shelf
=>
- 25
Coverting the mixed fraction to fraction,
=>
- 25
=>
- 25
=>1.375
Answer:
0.30 m
Step-by-step explanation:
<u>Explanation</u>:-
Given data is 30 % of m
Algebraic expression:-
The form of the algebraic expression is ax+ by +c
Given data is 30 % of m
here 'of' meaning is multiplied of given term
therefore 
The algebraic expression is 0.30 m
Answer:
<h2>R-{5}</h2>
Step-by-step explanation:
f(x)=x²-25=(x-5)(x+5)
g(x)=x-5
(f/g)(x)=<em>(x-5)</em>(x+5)/<em>(x-5)</em>=x+5; for x≠5
D=R-{5}
Answer: A. f(g(x)) =x and g(f(x))=x and f and g are inverses.
Step-by-step explanation:
A function <em>g</em> is the inverse of function <em>f</em> if
<em>f(g(x)) = g(f(x))=x</em>
Given: f(x)= x+4 , g(x) = x-4
f(g(x)) = f(x+4) = (x-4)+4
= x-4+4 = x
i.e. f(g(x)) =x
g(f(x))= g(x-4) = (x-4)+4 =x
i.e. g(f(x))=x
Hence, f(g(x)) =x and g(f(x))=x and f and g are inverses.
