12x < 96 = x <96/12 = x = 8 . hope this helps :)
Answer:
15.625
Step-by-step explanation:
V=wxhxl=2.5x2.5x2.5=15.625
The volume is around 50.27
the surface area is: 75.4
the perimeter 25.13

Answer: 11/50</h3>
Explanation:
This may seem like a trick question, but it's not. Your teacher simply wants to know how many times you got blue out of the number of times total. The numerator is the number of blue. The denominator is the number of total tries. The fraction 11/50 cannot be reduced because 11 and 50 share no common factors other than 1.
Notes:
- 11/50 = 0.22 = 22%
- The answer above applies to experimental probability only. The theoretical probability is likely different. We don't have enough info to compute the theoretical probability.
True, Every normal unitary operator u: x! x exists.
False, An if only if it is invertible, a matrix qualifies as unitary.
What is the matrix?
A group of numbers built up in a rectangular array with rows and columns. The elements, or entries, of the matrix, are the integers. In addition to numerous mathematical disciplines, matrices find extensive use in the fields of engineering, physics, economics, and statistics.
Here, we have
a. Every unitary operator U:X→X is normal as an operator A is unitary if A*A = AA* = I and an operator is normal if A*A = AA*.
Hence, every unitary operator u: x → x is normal.
b. A unitary matrix is always invertible but an invertible matrix need not be unitary. An invertible matrix A is unitary if A⁻¹ = A*
Hence, it is not true.
