slavikrds [6]

Answer:

The correct answer is 0.125.

Step-by-step explanation:

Anne has 8 unmarked computer disks in a box, namely one of English, Spanish, Mathematics, computer science, biology, SAT preparation, college applications, and American history.

Let the experiment be to pick up the SAT preparation disk from this set of 8 disk

Possible outcome is only one as there is only one SAT preparation disk.

Total number of outcomes, i.e. total number of disks available is 8.

Probability of picking of SAT preparation disk is

Probability = $\frac{possible outcomes}{All outcomes}$ = $\frac{1}{8}$ .

In a right triangle, the hypotenuse has endpoints P(–3, 2) and Q(1, –3). On a coordinate plane, line P Q has points (negative 3,

Answer:

The length of PR is 5 units

Step-by-step explanation:

Here, we want to calculate the length of PR

Since PQ is the hypotenuse, it means that the right-angle would be between lines PR and RQ

Also, since R is on the third quadrant, then its coordinates are (-x,-y)

To get the coordinates of R since we know that we need a right angle, we drop a straight vertical line through P and a straight horizontal line through Q

What this mean is that the coordinates of R will take the x-coordinate of the point P and the y-coordinate of the point Q

Hence, we have that the coordinates of the point R is (-3,-3)

Now, we want to calculate the length of PR

PR will be the distance between the points P and R

Mathematically, to get this, we use the distance formula

That will be;

√(y2-y1)^2 + (x2-x1)^2

Thus, we have

√(2-(-3)^2 + (-3-(-3))^2

= √5^2 + 0^2

= √25 = 5 units
