5. Use the Pythagorean theorem to estimate the length of the unknown side of the right triangle. Explain why
photoshop1234 [79]

Answer:

Step-by-step explanation:

a^2 + b^2 = c^2

6 = b

c= 8

a=?

now u just replace

a^2 + 6^2 = 8^2

a^2 + 32 = 64

a ^2 = 64-32

a^2 = 32

\sqrt a^{2}  = \sqrt32

a     = 5.65685424949

if you rounded

a = 5,7

Si yo tengo una canasta llena de mangos y piñas, de las cuales hay 30
skelet666 [1.2K]

Respuesta: Es más probable sacar un mango.

Explicación:

La probabilidad se refiere a la posibilidad de que un evento occura y no otro. En el caso que se describe, la probabilidad de sacar cada fruta puede ser calculada dividiendo el total de cada fruta en el número de frutas totales:

Probabilidad de sacar un mango:

\frac{cantidad de mangos}{cantidad de frutas en la canasta} =  \frac{30}{50}  =0.6

Probabilidad de sacar una piña:

\frac{cantidad de pinas}{cantidad de frutas en la canasta} = \frac{20}{50} = 0.4

De acuerdo a lo anterior la probabilidad de sacar un mango es de 0.6 o de 60% (multiplica la probabilidad por 100 para saber su equivalente en porcentaje), mientras que la probabilidad de sacar un mango es de 0.4 o 40% lo cual es mucho más bajo. Es decir que es más probable sacar un mango.
