Answer:

-7/4

Step-by-step explanation:

Recall that slope, m, is defined as the ratio rise to run: rise/run.

Note that if we start at x = -2 (an arbitrary choice), and move 6 units to the right, we end up at x = 4. This is the 'run.' Simultaneously, y starts at 1 and decreases to - 6, a change of -7.

Thus, the slope of the line through these two points is m = rise/run = -7/4

borishaifa [10]

Answer:

$Pr = \frac{1}{870}$

Step-by-step explanation:

Given

$n =30$

Required

Probability of selecting 2 toys of different types

From the question, we understand that all toys are different i.e. 1 of each type.

And the selection is without replacement;

So, after the first toy is selected; there are n - 1 toys left.

So, the probability is:

$Pr = \frac{1}{n} * \frac{1}{n - 1}$

Substitute $n =30$

$Pr = \frac{1}{30} * \frac{1}{30- 1}$

$Pr = \frac{1}{30} * \frac{1}{29}$

$Pr = \frac{1}{30*29}$

$Pr = \frac{1}{870}$
