Answer:

Distance=\sqrt{85}

Step-by-step explanation:

The distance between two points can be find by using the distance formula:

The distance between two points (x_1,y_1) and (x_2,y_2) can be find by:

       Distance=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

For the points :  

           (-2,5)\\and \\(4,-2)

Distance=\sqrt{(4-(-2))^2+(-2-5))^2} \\\\=\sqrt{(4+2)^2+(-7)^2} \\\\=\sqrt{6^2+(-7)^2} \\\\=\sqrt{36+49}\\\\ =\sqrt{85}

The distance between the two points is: \sqrt{85}

GEOMETRY HELP PLEASE!!! FAST!!!
Lubov Fominskaja [6]

The <em><u>correct answer</u></em> is:

Rotation of 90° counterclockwise about the origin  and a translation 2 units right

Explanation:

A rotation 90° counterclockwise maps each point (x, y) to (-y, x).  This means our points would be:

A(-4,3)→(-3, 4); B(-1,3)→(-3, -1); C(-2,1)→(-1, -2)

A translation 2 units right will add 2 units to the new x-coordinates; this gives us

(-3, 4)→(-1, 4); (-3, -1)→(-1, -1); and (-1, -2)→(1, -2)

These are the points in the image, so this is the correct set of transformations.

A study claims that the mean age of online dating service users is 40 years. Some researchers think this is not accurate and wan
Mademuasel [1]

Answer: H_0:\mu=40

H_0:\neq40

Step-by-step explanation:

  • A null hypothesis is a hypothesis where a researcher generally try to disprove, it says that there is no statistically significant relationship between the two variables .
  • An alternative hypothesis says that there is a statistical significance  between two variables.

Claim 1. : Mean age of online dating service users is 40 years.

i.e. \mu=40, since it has equals sign so we take this as null hypothesis.

Claim 2. : Mean age of online dating service users is not 40 years.

\mu\neq40

⇒ Null Hypothesis : H_0:\mu=40

Alternative hypothesis : H_0:\neq40
