Write the equation in exponential form log4 1/6=-2

1 answer:

8 0

Remember: logax=b⇒ab=x

in which "a" is the base of the log.

log4 (1/16) = 4^-2 = 1/4^2 = 1/16

4 to the power of -2 is equal to 1/16.

To answer this question, the equation in exponential form of "log4 (1/16) = -2" is " 4^-2 " (4 to the power of -2). :D

Answer:

Two angles are called complementary when their measures add to 90 degrees. ∠1 is 60 degrees ∠2 is 30 degrees so if you add it up, the answer is 90 degrees.

∠4 + ∠3 = answer has to be 90 degrees to call it a complementary angle

30 degrees + 60 degrees = 90 degrees

A single card is drawn from a standard 52-card deck. Let B be the event that the card drawn is a black, and let F be the event

Answer:

0.6154 or 61.54%

Step-by-step explanation:

The joint probability P(B′∪F) is given by the sum of each individual probability minus the intersection between both probabilities (red face cards).

$P(B'\cup F) = P(B')+P(F)-P(B'\cap F)$

The inverse probability of a card being black is also the probability of a card being red, which is 26 in 52. There are 12 face cards in a 52-card deck, 6 of which are not black, therefore:

$P(B'\cup F) = \frac{26}{52} +\frac{12}{52}-\frac{6}{52}\\P(B'\cup F) = \frac{32}{52} = \frac{8}{13} =0.6154$
