3 0

Answer:

Step-by-step explanation:

You are multiplying the identity matrix by another matrix.  

The effect of multiplying

1  0  0

0  1  0

0  0  1

by another matrix of the same dimensions is nil...nothing happens.  So, the answer to this problem is the first matrix itself.  Just copy it down.

Margot has started a construction and has this drawn on her paper. What is she constructing?
baherus [9]

For a better understanding of the explanation provided here, please find the diagrams in the two files that have been attached.

As can be clearly seen from the diagram, PR and QS are the diameters of the circle and they intersect each other at the centre, O of the circle.

The angle these diameters make at the point of intersection O is 90 degrees.

If Margot joins the points P,Q,R and S which are on the circumference of the circle, then we will get a square with sides PQ, QR, RS and SP as shown in the second diagram.

Thus, the correct option is Option A.

1) Which of the following shows the correct steps to find the value of 27 1/3?
sesenic [268]
First of all, we need to know: 3^3 = 3 x 3 x 3 = 9 x 3 = 27

So:

(27)^{\frac{1}{3}} = (3^3)^{\frac{1}{3}} = (3)^{3\times \frac{1}{3}} = 3^{1} = 3

So, your answer is D.

In a jury trial, suppose the probability the defendant is convicted, given guilt, is 0.95, and the probability the defendant is
Artyom0805 [142]

Answer:

The probability of the defendant is innocent given the defendant is convicted is P=0.006.

Step-by-step explanation:

Being:

G: guilty, I:innocent, C: convicted, A: acquitted.

We need to calculate P(I|C).

Being innocent, given convicted, is equal to the probability of being innocent and convicted divided by the probability of being convicted (innocent or guilty)

P(I|C)=\frac{P(I\&C)}{P(C)}

The probability of being innocent and convicted is

P(I\&C)=P(C|I)*P(I)=0.05*0.1=0.005

The probability of being convicted is equal to the sum of P(I&C) and P(G&C)

P(C)=P(I\&C)+P(I\&C)=P(C|I)*P(I)+P(C|G)*P(G)\\\\P(C)=0.005+0.95*0.90=0.005+0.855=0.86

Then,

P(I|C)=\frac{P(I\&C)}{P(C)}=\frac{0.005}{0.86}= 0.006
