Answer: 1/3

Step-by-step explanation: In this problem, we're asked to find the probability of selecting a blue marble from a bag without looking.

Start with the ratio for the probability

of an event which is shown below.

P(event) <em>= number of favorable outcomes/total number of outcomes</em>

Since there are 3 blue marbles in a bag, the number of favorable outcomes is 3 and since there are 12 marbles in all and it's equally likely that we will choose any of the marbles, the total number of outcomes is 12 so we have 3/12.

Therefore, the probability of choosing a blue marble is 3/12.

However, notice that 3/12 can be reduced to 1/3.

So the final answer for the probability of choosing a blue marble is 1/3.

(-3, -2) is the vertex. 

You can find this by plugging into -b/2a to find the x value and using the x value to find the y value. 

And another spot on the vertex would be (0, 16), which is the y intercept.

Explain why this matrix equation has no solution: A 11 17 −8 13 = 0 0 0 0.
qwelly [4]

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.
