Answer:
.......................
Step-by-step explanation:
The answer is not defined.
Explanation:
The given matrix is
The matrix has dimensions
This means that the matrix has 2 rows and 2 columns.
Also, the matrix has dimensions
This means that the matrix has 2 rows and 1 column.
Since, the matrices can be added only if they have the same dimensions.
In other words, to add the matrices, the two matrices must have the same number of rows and same number of columns.
Since, the dimensions of the two matrices are not equal, the addition of these two matrices is not possible.
Hence, the addition of these two matrices is not defined.
7x-4=3x+ 8
-3x of both sides 4x-4=8
plus 4 to both sides 4x=12
12 divide by 4 = 3

Answer:
0.50
Step-by-step explanation:
Let A represent the probability that it will be cloudy
Let B represent the probability that it will be rainy
P(A) = 0.40
P(B) = 0.30
P(A and B) = 0.20
For non mutually exclusive events the probability of event A or B is
P(A or B) = P(A) + P(B) - P(A and B)
= 0.40 + 0.30 - 0.20
= 0.50
There is a 50% probability that the picnic will be postponed. Therefore the probability that the picnic will not be postponed is equals 1 - P(A and B)
= 1 - 0.50
= 0.50 or 50%
