Answer:
BC:BN=8:3
Step-by-step explanation:
ABCD is a trapezoid and there is a point m which belongs to AD such that AM:MD=3:5.Line "l" parallel to AB intersects the diagonal AC at p and BD at N.
Now, we know that the parallel lines divide the transversal into the segments with equal ratio, therefore, BN:NC=AM:MD
But, BC= BN+NC
Therefore, BC:BN=(BN+NC):BN
⇒BC:BN=(3+5):3
⇒BC:BN=8:3
Answer:
There is a 45.05% probability that the selected person is a right-handed female.
Step-by-step explanation:
We have these following probabilities
A 50% probability that a person is a male
A 50% probability that a person is a female.
A 12.6% probability that a male is left-handed.
A 9.9% probability that a female is left-handed.
If a person is selected at random, to find the probability that the selected person is a right-handed female, one would compute:
50% are female.
9.9% of the females are left-handed, so 100-9.9 = 90.1% of the females are right handed.
So

There is a 45.05% probability that the selected person is a right-handed female.
The inverse of the function is 
Explanation:
To find the inverse of the equation
, we need to interchange the variables x and y for the variables y and x.
Thus, the equation becomes

Now, we shall find the value of y.
Now, adding 8 to both sides of the equation, we have,

Interchanging the sides,

Dividing by 2 on both sides,

Taking square root on both sides,

Thus, the inverse of the function is
