Verdich [7]

Answer:

\frac{3}{14}

Step-by-step explanation:

Total Students = 28

Brown Hair = 22

NOT Brown Hair = 28 - 22 = 6

The probability of an event is the number of that event divided by total number.

So, let denote probability of without brown hair be  P(NOT BROWN). So, we can say:

P(NOT BROWN) = 6/28

Reducing, we get:

P(NOT BROWN) = 3/14

Vlad [161]
<span>Length = the longer side

He wants to build a table with a length of 9ft.

The plans he has are 18ft x 36ft
Length of the plans =  36ft
Compare the length of the plans to the length he wants:
36 ft vs 9 ftThe length in the plans is 4 times longer than the length he wants.<span>

</span>Length he wants / Length of plans = your dilation scale factor

9 / 36 = ¼
1/4 = dilation scale factor

Hope this answers your question, and May the Force Be With You!
