The probability of there being zero males is given by:

Similarly the probability of there being zero females is also 1/16.
The probability there will be at least 1 male and 1 female is therefore:

The answer is: 7/8.
Well if the room is square then you ned to find the square root of the area.
Find 
Answer:
All except the second one (angle g is not similar to angle r)
Step-by-step explanation:
Just look at the order of the letters. It it's the same, its similar.
Answer:
For c=5 there are not solutions for the compound inequality
Step-by-step explanation:
we know that
In the compound inequality
-----> inequality A
-----> inequality B
The solution of the system of inequalities must satisfy inequality A and must satisfy inequality B
so
If c=5
then
There is no solution that satisfies both inequalities simultaneously.
therefore
For c=5 there are not solutions for the compound inequality
Solve either equation for either variable. Since the second one has y on its own, the easiest choice is to solve that for y.
-5x + y = 13 ⇒ y = 5x + 13
Now substitute this into the other equation to eliminate y and rewrite it entirely in terms of x :
-3x + 3y = 3 ⇒ -3x + 3 (5x + 13) = 3
Simplify and solve for x :
-3x + 15x + 39 = 3
12x = -36
x = -3
Substitute this into either original equation to solve for y. Plugging x = -3 into the first equation would give
-3 (-3) + 3y = 3
9 + 3y = 3
3y = -6
y = -2
So the solution to the system of equations is (x, y) = (-3, -2).
