If m(x) = x+5/x-1 and n(x) = x — 3, have the same domain as (m • n) (x)
Yuri [45]

For this case we have the following functions:

m (x) = \frac {x + 5} {x-1}\\n (x) = x-3

By definition we have to:

(f * g) (x) = f (x) * g (x)

So:

(m * n) (x) = m (x) * n (x)\\(m * n) (x) = \frac {x + 5} {x-1} (x-3)\\(m * n) (x) = \frac {(x + 5) (x-3)} {x-1}

By definition, the domain of a function is given by the values for which the function is defined.

The domain of m(x) is given by all reals except 1.

The domain of n(x) is given by all reals.

While the domain of (m * n) (x) is given by:

All reals, except the 1. With x = 1, the denominator is 0 and the function is no longer defined.

Answer:

Domain of(m * n) (x) is given by all reals except 1.

If the critical z-value for a hypothesis test... If the critical z-value for a hypothesis test equals 2.45, what value of the te
schepotkina [342]

Answer: z score = 0.00714

Step-by-step explanation: the value of test statistics is gotten using the standard normal distribution table.

Z= 2.45 has area to the left (z<2.45) and area to the right (z>2.45).

Level of significance α is the probability of committing a type 1 error. The area under the distribution is known as the rejection region and it is the area towards the right of the distribution.

The table I'm using is towards the left of the distribution.

But z>2.45 + z<2.45 = 1

z> 2.45 = 1 - z<2.45

But z < 2.45 = 0.99286

z > 2.45 = 1 - 0.99286

z >2.45 = 0.00714

Hence the test statistics that would produce the least type 1 error is 0.00714
