Answer:
2. (only)
Step-by-step explanation:
The Pythagorean theorem tells you the sum of the squares of the two legs of a right triangle is equal to the square of the hypotenuse. To determine if these are right triangles, determine if that condition is met.
1. 3^2 +5^2 = 9 + 25 = 34 ≠ (√35)^2 . . . . not a right triangle
2. 5^2 +4^2 = 25 +16 = 41 = (√41)^2 . . . a right triangle
3. 6^2 +8^2 = 36 +64 = 100 ≠ (√10)^2 . . . . not a right triangle
4. 3^2 +3^2 = 9 +9 = 18 ≠ (3√3)^2 = 27 . . . . not a right triangle
These two problems are equivalent
The experimental probability is
(number of times it stopped over Sect. 2) / (total number of times you tried it)
Number of times it stopped in Section-2: 36
Total number of times you tried it: (20 + 36 + 24) = 80
Experimental probability of Section-2 = 36/80 = 9/20 = 45%
Answer:
<h2>462</h2>
Step-by-step explanation:
15% of 840 is 126
30% of 840 is 252
252
<u>+ 126 </u>
<em> 378</em>
<em></em>
840 - 378 = <em>462</em>
or
--------------------------------------------------------------------------------------------------------------
55% of 840 is...
<em>462</em>
--------------------------------------------------------------------------------------------------------------
