I believe it’s X = 4
So 4 would be the answer
Answer:
D. 3 1/2
Step-by-step explanation:
Sum means addition (+)
Sum of a number, x and 1/2=4
This means the addition of the two numbers
x+1/2=4
Make x the subject of formula
x=4-1/2
Finding the L.C.M
= 8-1/2
x=7/2
x=3 1/2
The matrix equation has no solution because the same matrix of equal magnitude and opposite in nature is been added to it.
Given to us
A + [11 17 -8 13] = [0 0 0 0]
<h3>What is the value of matrix A?</h3>
We know that the given matrix will give values as zero if the same matrix is been deducted from it, therefore,
A + [11 17 -8 13] = [0 0 0 0]
A = [0 0 0 0] - [11 17 -8 13]
A = [-11 -17 +8 -13]
Thus, the matrix is equal to [-11 -17 +8 -13].
<h3>why this matrix equation has no solution?</h3>
The matrix equation has no solution because the same matrix of equal magnitude and opposite in nature is been added to it, therefore, [11 17 -8 13] is been added to it.
Thus, the sum of the two matrices has no solution.

Answer:
The probability that Joe's stock will go up and he will win in the lottery is 0.00005.
Step-by-step explanation:
Let the events be denoted as:
<em>X</em> = the stock goes up
<em>Y</em> = Joe wins the lottery
Given:
P (X) = 0.50
P (Y) = 0.0001
The events of the stock going up is not dependent on the the event of Joe winning the lottery.
So the events <em>X</em> and <em>Y</em> are independent of each other.
Independent events are those events that can occur together at the same time.
The joint probability of two independent events <em>A</em> and <em>B </em>is,

Compute the value of P (<em>X ∩ Y</em>) as follows:

Thus, the probability that Joe's stock will go up and he will win in the lottery is 0.00005.
