Hi,


Work:

Equation;

( {2}^{4} )^{2}  =  {2}^{n}

Write an expression in the exponential form with a base of 2.

{2}^{8}  =  {2}^{n}

Since bases are the same, set the exponents equal.

8 = n

Switch the sides (RESULT)

n = 8


Hope this helps.

Given that a randomly chosen quadrilateral has four right angles, what is the probability that the quadrilateral also has four e
Alexxx [7]

Answer:

0.25

Step-by-step explanation:

This is the question on conditional probability

Let A - the quadrilateral has four right angles

B - the quadrilateral has four equal side lengths

Required probability = P(B/A)

By definition of continuous probability

P(B/A) = \frac{P(AB)}{P(A)}

P(AB) = \frac{2}{20} =0.10

P(A) = \frac{8}{20} =0.4

Hence given probability = \frac{0.1}{0.4} =0.25
