Answer:
Reinaldo es ingeniero
Step-by-step explanation:
Por los datos del problema sabemos que Jeferson es casado. También sabemos que el profesor se casará pronto, así que:
Jeferson no es profesor
Reinaldo debe tomar el metro para visitar al médico, así que no es vecino de ninguno. Como el médico y el profesor son vecinos, entonces Reinaldo no es médico ni profesor, asi que
Reinaldo es ingeniero
Podemos saber además que si Jeferson no es profesor (ya demostrado) ni tampoco es ingeniero, entonces
Jeferson es médico
Por descarte, Yasir es profesor
Answer: A
Step-by-step explanation: when Constructing a confidence interval, it is important to take note of the margin of error which is given by the formulae below
Margin of error = critical value × σ/√n.
Where n is the sample size.
As we can see that the critical value is a constant and the population standard deviation.
Hence there is an inverse relationship between margin of error and sample size, which implies that a large sample size produces a small margin of error.
If the margin of error is small, it means the sample size will increase the like hood that the sample is a good representation of the population.
Answer:
1.22 feet, or 1 11/50 ft

Answer:
Step-by-step explanation:
g(x)= -2 x^2 + 3 x - 5
g(-2) = -2 . (-2)^2 + 3. (-2) - 5 = -2 . 4 - 6 - 5 = - 8 - 6 - 5 = - 19
g(0) = -2 . (0)^2 + 3 . 0 - 5 = -2 . 0 + 0 - 5 = 0 + 0 - 5 = - 5
g(3) = -2 . (3)^2 + 3 . (3) - 5 = -2 . 9 + 9 - 5 = -18 + 9 - 5 = - 14
