Answer:
2^2 - 1^2
Step-by-step explanation:
1^1 = 1
2^2 = 4
4-1 =3
2^2 - 1^1 = 3
Answer:
b) The property states that ab is equivalent to b a
Step-by-step explanation:
<em>Commutative property</em>:-
the commutative property , when we multiply two integers , the answer we get after multiplication will remain the same, even if the position of the integers are interchanged.
Let 'a' and 'b' be the two integers , then ab = b a
Example:-
. 1 X 2 = 2 X 1 = 2
. 12 X 5 = 5 X 12 = 60
Answer:
A.58.81
Step-by-step explanation:
x = number of parties attended
y = number of text messages sent
The residual is the difference between the actual number of text messages sent (200) and the number of texts predicted by the regression model:

The residual is:

The answer is alternative A.58.81
Answer:
length of the photograph will be 4.2 in. after pressing the button 5 times.
Step-by-step explanation:
By pressing the button, every time size of the photograph gets reduced by 12%.
Therefore, the sequence formed by the reduced sizes of the photo will be a geometric sequence and the formula for the size of the reduced image will be,
L = 
Where l = Actual length of the photograph
L = length of the reduced image
n = Number of times the button has been pressed
For l = 8 in. and n = 5
L = 
= 
= 4.22 in
L ≈ 4.2 in.
Therefore, length of the photograph will be 4.2 in. after pressing the button 5 times.
