Answer:
B
Step-by-step explanation:
That was actually trickier than I thought it would be
I was looking for 4(x-4), but 4(x-2)(x+2) also works
Given:
The given value is 
.
To find:
The multiplicative inverse of .
Solution:
We know that 
is the multiplicative interval of 
if 
.
Let be the multiplicative inverse of the given value . Then,
Divide both sides by .
Therefore, the multiplicative inverse of is 
. Hence the correct option is A.
Answer:
The variance is 53.29 kg²
Step-by-step explanation:
The standard deviation is the square root of the variance.
So
In which problem, we have that:
So
The variance is 53.29 kg²
Answer:
There will be 135 squares in total. Changing the order of the factors wont change the result.
Step-by-step explanation:
(i am assuming that sqaures = sqaure pieces)
Each section has 3 rows of 15 square pieces, therefore each section has 3*15 = 45 sqaure pieces. Thus, the complete guilt will have 45*3 = 135 square pieces. Since all we do were multiplications, changing the order of the factors wont change the value of the product.
