Which set of side lengths is a Pythagorean triple?<br> 1,3,10<br> 4,5,9<br> 9, 40, 41<br> 16, 30, 44

Elina [12.6K]

Answer:

Which set of side lengths is a Pythagorean triple? 9, 40, 41

Step-by-step explanation:

$c = \sqrt{ {a}^{2} + {b}^{2} }$

9 = a

40 = b

41 = c

$c = \sqrt{ {a}^{2} + {b}^{2} } \\ c = \sqrt{ {9}^{2} + {40}^{2} } \\ c = \sqrt{81 + 1.600} \\ c = \sqrt{1.681} \\ c = 41$

24 is 0.6% of what number

algol [13]

Hello! The answer would be,
38.4
Since if you do 24x0.6 you would get 14.4 which then you would add
14.4 with 24 and get 38.4
Hope I've helped and feel free to ask me questions!

Sincerely, Kaylie :)

A probability experiment is conducted in which the sample space of the experiment is S 1,2,3,4, 5,6,7,8, 9, 10, 11, 12]. Let eve

Alenkinab [10]

Answer:

$E\ n\ F = \{1, 5, 6,7\}$

$F\ n\ G =\{9\}$

$F\ U\ G =\{1,5,6, 7, 8,9,10, 11, 12\}$

$P(F\ U\ G) = \frac{3}{4}$

Step-by-step explanation:

Given

$S = \{1,2,3,4, 5,6,7,8, 9, 10, 11, 12\}$

$E = \{1,2, 3, 4, 5, 6,7\}$

$F =\{1,5,6, 7, 8,9\}$

$G = \{9,10, 11, 12\}$

$H = \{2, 3, 4\}$

Solving (5): E and F

Sets of E and F = E n F

$E\ n\ F = \{1,2, 3, 4, 5, 6,7\}\ n\ \{1,5,6, 7, 8,9\}$

List out common elements

$E\ n\ F = \{1, 5, 6,7\}$

<em>They are not mutually exclusive because </em> $n(E\ n\ F) \neq 0$ <em />

Solving (6): F and G

Sets of F and G = F n G

$F\ n\ G =\{1,5,6, 7, 8,9\}\ n\ \{9,10, 11, 12\}$

List out common elements

$F\ n\ G =\{9\}$

<em>They are not mutually exclusive because </em> $n(F\ n\ G) \neq 0$ <em />

Solving (7): F or G and P(F or G)

Sets of F or G = F U G

$F\ U\ G =\{1,5,6, 7, 8,9\}\ U\ \{9,10, 11, 12\}$

List all elements without repetition

$F\ U\ G =\{1,5,6, 7, 8,9,10, 11, 12\}$

Solving P(F U G)

$P(F\ U\ G) = \frac{n(F\ U\ G)}{n(S)}$

$n(F\ U\ G) = 9$

$n(S) = 12$

Hence;

$P(F\ U\ G) = \frac{9}{12}$

Divide by 3

$P(F\ U\ G) = \frac{3}{4}$
