A
A square matrix is invertible if its determinant is not zero.
The determinant for this matrix is
so it does not have an inverse because its determinant is zero.
Well first add up all the numbers of marbles (which is 34 in total) and divide it by the number of black marbles.
(which should give you 8/34)
Then simplify the fraction and you should get 4/17
The union of the two sets is the combining of the two sets, so the correct answer is A. {4, 8, 10, 12, 14}.
Hope this helps =)
Answer:
<h2>9cm and 5cm </h2>
Step-by-step explanation:
Note: The unit of the width in the question is suppose to be in cm
<em>"with length 18cm and width 10m"====>>></em> <em>"with length 18m and width 10m"</em>
so given that the dimension of the room is
<em>18mx10m </em>
This is a reduction process since we aim to transfer the dimension to paper
we are reducing the dimension by 2
and 1cm---2m
since 2m will represent 1cm
then the dimension will be
9cm and 5cm
