Answer:

  -1/6

Step-by-step explanation:

A suitable calculator can evaluate this for you and show you the result as a fraction.

You start with the multiplication in the inner-most set of brackets. Here, those brackets are the absolute value function.

  -2(-1/3) = +2/3

Then the sum in those brackets:

  -5/6 +2/3 = -5/6 +4/6 = -1/6

The absolute value changes the sign of this back to positive, so the value in square brackets is ...

  3 -(1/6) = 18/6 -1/6 = 17/6

Finally, this value is divided by -17, so you have ...

  \dfrac{17}{6}\div(-17)=\dfrac{17}{6}\cdot\dfrac{-1}{17}=-\dfrac{17\cdot1}{17\cdot6}=\boxed{-\dfrac{1}{6}}

I need help on my math please
Dovator [93]
In a 2-way frequency table, you take the row entry and divide it by its row total to get a decimal.
For your example:
It starts out like this:
            sunny   snowy
Male:       17      11
Female:   15      16

Add the rows up. 
            sunny   snowy       total
Male:       17      11              28
Female:   15      16             31

Then divide the number the by the total:   
            sunny           snowy       total
Male:       17/28        11/28              28
Female:   15/31        16/31             31      

Yours says to round to the 1000th place, so it ends up like:
            sunny   snowy     
Male:       .607      .393     
Female:    .484      .515
 
 Hope that helps!!

Someone please explain this it’s confusing me.

Answer:

x = 4 radical 3 / 3

Step-by-step explanation:

this is a 30-60-90 triangle

the side across from the angle 30 is L

the side across from the angle 60 is L√3

the side across from the angle 90 is 2L

we are given the side across from 60⁰ so we know that:

2 = L√3

we want to solve for L, so we must divide both sides by √3 (radical three)

2/√3 = L√3/√3

you would get 2/ √3 = L, because the radical three cancels out on the L side.

but you can't have a radical in the denominator, so you have to multiply 2/√3 by radical 3

2 times √3 and √3 times √3

you get 2√3/√9

radical nine can simplify

2radical3/3 or 2√3/3

we found L, but that would equal the thirty degree angle, not the 90, 90 = 2L

multiply the number infront of the radical by two and get

4√3/3

x=4 radical 3 divided by 3
