Answer:
0.4444
Step-by-step explanation:
Use the following property to ease the calculation:
P(At least one)=1-P(None)
Total number of electrical components: 9
Number that does not function well :1
Number that functions well : 8
We have ways to to choose 4 good components from 8.
We have ways to choose 4 components from a total of 9.
If all function properly then none is bad, we way to do this.
P(At least one)=
P(At least one)=
P(At least one)=0.4444
In this question, it is given that An inverse trigonometric function is used to find the value of an unknown obtuse angle in a triangle. The inverse function returns the angle 68°.
Since the angle is obtuse angle, it means the measurement of the angle is greater then 90 degree. And to find the angle measurement, we have to subtract the given angle from 180 degree.
So the unknown angle is
And that's the required answer .
Answer:
3 unidades de comprimento
Step-by-step explanation:
O perímetro é definido como a soma de todos os lados.
O perímetro de um quadrado de lado 2x é dado por:
O perímetro de um retângulo de comprimento x e largura x² é dado por:
Para que ambos os perímetros sejam iguais:
O valor de x é igual a 3 unidades de comprimento.
