What is the value of x log3 x=4

Answers

Answer:

x=81

Step-by-step explanation:

Rewrite log_3 (x)=4 in exponential form using the definition of a logarithm. If x and b are positive real numbers and b≠1, then log_b(x)=y is equivalent to b^y=x.

Rewrite the equation as x=3^4

Raise 3 to the power of 4 

x=81

The numbers 1 through 50 are written with red marker on slips of paper while the numbers 51 through 100 are written with blue marker on slips of paper. All the papers are put into a bag and shuffled. One card is
randomly selected.
a. Find the probability of selecting a number less than 16 or a number written in red.
b. Find the probability of selecting a number written in blue or a multiple of 5.

Answers

A. we want to pull 15 or less from the bag and there are 100 possibilities
(15)/(100)=(3)/(20)
the probability is 3 out of 20

B. we are trying to pull a 55,60,65,75,80,85,90,95,or 100 that is 9 possibilities out of 100

(9)/(100)  is the possibility of pulling a multiple of 5 that is blue 
 
a. The probability of picking a number less than 16 or a number in red is 65/100.
b. The probability of picking a number written in blue or a multiple of 5 is 70/100.
