First, find the slope (m):   m = \frac{y2 - y1}{x2 - x1} = \frac{7 - 2}{3 - (-1}) = \frac{5}{4}

Next, input ONE of the points (x₁, y₁) and the slope into the Point-Slope formula:

y - y₁ = m(x - x₁)

y - 7 = \frac{5}{4}(x - 3)

Lastly, isolate "y" to find the Slope-Intercept formula: y = mx + b

y - 7 = \frac{5}{4}x - \frac{15}{4}

    y = \frac{5}{4x}  + \frac{13}{4}

A box contains 35 gems, of which 10 are real diamonds and 25 are fake diamonds. Gems are randomly taken out of the box, one at a
Sonja [21]

Answer:

Step-by-step explanation:

The total number of ways of selecting 3 gems of any kind without replacement is 35 * 34 * 33 = 39270

Now selecting 2 gems from 25 is 25C2

25 C 2 = 25 * 24/2 = 300

Selecting one good gem is 10

Total selection = 300 * 10 = 3000

P(gems) = 3000 / 39270

P(gems) = 300/3927

P(gems) = 100/1309

To answer this problem, the utilization of the provided formula is of utmost importance.

The formula to be used would be for the combination with no repetition since it is what is asked and possibly happens when involving the products mentioned in the problem. The formula would be

      n!                                              where in
-------------                                                   n = number of things to choose from
(n - r)! r!                                                      r = number of things needed to form

the symbol ! is called a factorial function which replaces the sequence of multiplying a number in a descending order.

lets substitute and solve

      13!
--------------
(13 - 6)! 6!

      13!
-------------
   (7!) 6!

6,227,020,800
-------------------
  5,040 x 720

6,227,020,800
-------------------
    3,628,800

1,716

The answer would be 1,716.
