Ivahew [28]

Answer:

f(x)=x^2+6x+9

Step-by-step explanation:

We are required to represent the expression given in the standard form to the quadratic form

Given

f(x) = (x + 3)^2

let us square the given expression

f(x)=(x+3)(x+3)

open brackets

f(x)=x^2+3x+3x+9

sum the similar terms

f(x)=x^2+6x+9

Suppose a researcher is conducting a hypothesis test for a mean and finds a test statistic of z=2.3z=2.3 . Which of the choices
Galina-37 [17]

Answer:

Option c. The result is significant at the 0.020.02 level.

Step-by-step explanation:

We are given the following in the question:

We are conducting a one tailed hypothesis test with alternate hypothesis

H_A: \mu > \mu_0

The z test calculated for the same is

z=2.3

We calculate the p-value from the standard normal table.

p value = 0.010724 at 0.05 significance level.

The result is significant

p value = 0.010724 at 0.01 significance level.

The result is not significant

p value = 0.010724 at 0.02 significance level.

The result is significant at 0.02 significance level.

Thus, the correct answer is

Option c. The result is significant at the 0.020.02 level.
