<u>Trigonometry</u>

[Right Triangles Only] Pythagorean Theorem: a² + b² = c²

  • a is one leg
  • b is another leg
  • c is hypotenuse

Step-by-step explanation:

<u>Step 1: Identify Variables</u>

a = 19

b = <em>x</em>

c = 21

<u>Step 2: Solve for </u><em><u>x</u></em>

  1. Substitute [PT]:                    19² + x² = 21²
  2. Isolate <em>x</em> term:                      x² = 21² - 19²
  3. Exponents:                           x² = 441 - 361
  4. Subtract:                               x² = 80
  5. Isolate <em>x</em>:                               x = √80
  6. Simplify:                                x = 4√5

it rained nine days in the month of april .based on this ,what is the probaility that is does not rain on the first day of may?​
attashe74 [19]
<h3>Answer:     7/10</h3>

==========================================================

Explanation:

There are 30 days in April. Since it rained 9 of those days, the empirical probability of it raining in April is 9/30 = (3*3)/(3*10) = 3/10.

If we assume that the same conditions (ie weather patterns) hold for May, then the empirical probability of it raining in May is also 3/10. By "raining in May", I mean specifically raining on a certain day of that month.

The empirical probability of it not raining on the first of May is therefore...

1 - (probability it rains)

1 - (3/10)

(10/10) - (3/10)

(10-3)/10

7/10

We can think of it like if we had a 10 day period, and 3 of those days it rains while the remaining 7 it does not rain.
