Answer:
One of the obvious non-trivial solutions is .
Step-by-step explanation:
Suppose the matrix A is as follows:
The observed system after multiplying looks like this
Since we now that , where
are the columns of the matrix A, we actually know this:
Once we multiply and sum up these 3 by 1 matrices, we get that these equations hold:
This actually means that the solution to the previously observed system of equations (or equivalently, our system ) has a non-trivial solution
.
Answer:
Hello some parts of your question is missing below is the missing part
c. If you randomly select a navel orange, what is the probability that it weighs between6.2 and 7 ounces
Answer: A) 0.0099
B) 0.6796
C) 0.13956
Step-by-step explanation:
weight of Navel oranges evenly distributed
mean ( u ) = 8 ounces
std ( б )= 1.5
navel oranges = X
A ) percentage of oranges weighing more than 11.5 ounces
P( x > 11.5 ) =
= P ( Z > 2.33 ) = 0.0099
= 0.9%
B) percentage of oranges weighing less than 8.7 ounces
P( x < 8.7 ) =
= P ( Z < 0.4667 ) = 0.6796
= 67.96%
C ) probability of orange selected weighing between 6.2 and 7 ounces?
P ( 6.2 < X < 7 ) =
= P ( -1.2 < Z < -0.66 )
= Ф ( -0.66 ) - Ф(-1.2) = 0.13956
