Answer:

H

Step-by-step explanation:

given y = -x² + 3x.

let f(x) be y.

f(-2) = -(-2)² + 3(-2) = -10

f(-1) = -(-1)² + 3(-1) = -4

f(0) = -(0)² + 3(0) = 0

f(1) = -(1)² + 3(1) = 2

f(2) = -(2)² + 3(2) = 2

Assume that the significance level is a=0.05. Use the given information to find the P-value and the critical value(s). The test
Minchanka [31]

Answer:

The required P value is 0.0901.

The critical value for the test statistic is 1.645.

Step-by-step explanation:

Consider the provided information.

The test statistic of z=1.34 is obtained when testing the claim that p> 0.1

It is given given that z=1.34 as the claim has greater than inequality so it is a right tailed test.

Part (A) P-value

P\ value=1-P(Z\leq z)\\P\ value=1-P(Z\leq 1.34)

From the Standard normal distribution table P(Z\leq 1.34) =0.9099.

Therefore,

P\ value=1-0.9099=0.0901

Hence, the required P value is 0.0901.

Part (B) The critical value(s) is/are z=

It is given that the significance level is α=0.05

Using standard z value table we get the critical value for the test statistic is 1.645.

Hence, the critical value for the test statistic is 1.645.

Selina claims single having one exemption. Her state tax deduction is 21% of her federal tax contribution. Calculate the amount
Maurinko [17]

Based on the number of exemptions claimed by Selina and her biweekly gross pay, her state tax will be $16.80.

<h3>How much will Selina pay for state taxes?</h3>

Selina is to pay 21% of her federal taxes.

Seeing as she claims a single exemption and falls in the $840 to $860 bracket, the table shows that her federal tax contribution would be $80.

State taxes are therefore:

= 80 x 21%
= $16.80

PLEASE ANSWER THIS QUESTION RIGHT Name the x-intercept(s)?<br> A:0 and 4,B:2,C:4,D:0.
harina [27]

Answer:

A. 0 and 4

Step-by-step explanation:

The x-intercepts are simply the values of x when y = 0. In other words it is the points where the line curve intercepts or cuts across the x-axis.

Form the graph given, we can see that at x = 0 and x = 4, the value of y = 0. Simply put, the curve cuts the x-axis at x = 0 and x = 4.

x-intercepts are 0 and 4.
