What is the distance between the two end points (5,6) (-4,-7) round to the nearth two decimal places
garri49 [273]

The formula of a distance between two points:

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

We have:

(5,\ 6)\to x_1=5,\ y_1=6\\(-4,\ -7)\to x_2=-4,\ y_2=-7

substitute:

d=\sqrt{(-4-5)^2+(-7-6)^2}=\sqrt{(-9)^2+(-13)^2}=\sqrt{81+169}=\sqrt{250}\\\\=\sqrt{25\cdot10}=\sqrt{25}\cdot\sqrt{10}=5\sqrt{10}

A number cube is rolled what is the probability that the result is a number greater than five?
ki77a [65]

Answer:

The answer is 1/3

Step-by-step explanation:

Let the events of getting the no. greater than 4 be (>4).

Then,

<em>n</em><em>(</em><em>s</em><em>)</em><em> </em><em>=</em><em> </em><em>6</em>

<em>n</em><em>(</em><em>></em><em>4</em><em>)</em><em> </em><em>=</em><em> </em><em>2</em>

<em>P</em><em>(</em><em>></em><em>4</em><em>)</em><em> </em><em>=</em><em> </em><em>n</em><em>(</em><em>></em><em>4</em><em>)</em><em>/</em><em>n</em><em>(</em><em>s</em><em>)</em>

<em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em>=</em><em>2</em><em>/</em><em>6</em>

<em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em>=</em><em>1</em><em>/</em><em>3</em>

<em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em>

Your family orders delivery from a local restaurant
anyanavicka [17]

Answer:

1 person ordered chicken and 5 people ordered  steak

Step-by-step explanation:

Since we have equations already given, lets solve to get the answer.

<u>First, substitution</u>

  • x=6-y

<u>Then, as per the second equation</u>.

  • 14(6-y) + 17y = 99
  • 84-14y + 17y = 99
  • 3y=99-84
  • 3y= 15
  • y= 15/3
  • y= 5

<u>Then</u>

  • x=6-y
  • x=6-5
  • x=1

We got 1 chicken and 5 steak orders
