Answer:
Step-by-step explanation:
include the striking deviation because it may explain an unusual occurrence is correct. Striking deviations or outliers can be useful in describing data set.
Answer: 8
Step by Step:
5/50 = x/80
cross multiply
50x = 400
divide 50 from both sides
x = 8

Answer:</h2>
Ques 1)
Number of functions from X to X are:
Ques 2)
Number of relation from X to X are:
<h2>
Step-by-step explanation:</h2>
Relation--
A relation from a set A to set B is the set of all the ordered of the type:
(a,b) where a belongs to A and b belongs to B.
if A has m elements and B has n elements.
Then the total number of relation from A to B are:
Function--
A function from a set A to set B is the set of all the ordered pair where each element of set A is mapped to a single element of the other set.
i.e. every element has a single image.
if A has m elements and B has n elements.
Then the total number of functions from A to B are:
Answer:
-2(2x +5)² = -8x² -40x -50
Step-by-step explanation:
Evaluate from the inside out, according to the order of operations.
h(g(f(x))) = h(g(2x +5)) = h((2x +5)²) = -2(2x +5)² = -2(4x² +20x +25)
= -8x² -40x -50
I personally prefer the factored form, but that is not considered "simplified."
