Answer: The value of test statistic = -10.67

Step-by-step explanation:

Test statistic for proportion:

z=\dfrac{\hat{p}-p}{\sqrt{\dfrac{p(1-p)}{n}}}

, where p= population proportion

n= sample size

\hat{p} = sample proportion

AS per given,

p=0.94, n= 1004, \hat{p}=0.86

z=\dfrac{0.86-0.94}{\sqrt{\dfrac{0.94(1-0.94)}{1004}}}\\\\=\dfrac{-0.08}{\sqrt{\dfrac{0.0564}{1004}}}\\\\=\dfrac{-0.08}{\sqrt{0.0000561752988048}}\\\\=\dfrac{-0.08}{0.00749501826581}\\\\=-10.673756509\approx-10.67

i.e. the value of test statistic = -10.67

Determine the approximate value of x.
yarga [219]

Answer:

  C.  6.736

Step-by-step explanation:

The unmarked angle is 180-80-40 = 60 degrees. Given the angles of the triangle and one side length there is enough information to use the Law of Sines to solve the triangle--eliminating choice D.

The angle opposite x is larger than the angle opposite 5, so <em>x will be larger than 5</em>. That leaves only answer choice C: 6.736.

___

If you want to actually use the law of sines to determine x, you know that ...

  x / sin(60°) = 5 / sin(40°)

  x = 5·sin(60°)/sin(40°) . . . . . . multiply by sin(60°)

  x ≈ 6.736

Graph the following system of inequalities. y ≤ 1 3 ⁢ x − 2 x &lt; 4
VLD [36.1K]

By using an online graphing calculator, the solution to this system of inequalities are plotted in the image attached below.

<h3>How to graph a system of inequalities?</h3>

An inequality is a mathematical relation that compares two (2) or more integers and variables in an equation based on any of the following:

  • Less than (<).
  • Greater than (>).
  • Less than or equal to (≤).
  • Greater than or equal to (≥).

Given the following system of inequalities:

y ≤ 1/3x  ⇒ y - 1/3x ≤ 0

y - 2x < 4

By using an online graphing calculator, the solution to this system of inequalities are plotted in the image attached below.
