Answer:

it is!!

Step-by-step explanation:

it terminates after the tenths place, therefore, it can be made into a terminating decimal, which means its rational!! can i maybe get brainliest :D at least a thanks or a rating :D

An HR director numbered employees 1 through 50 for an extra vacation day contest. What is the probability that the HR director w

forsale [732]

Answer:

The probability that the HR director will select an employee who is not a multiple of 13 is $\frac{47}{50}$

Step-by-step explanation:

* Lets explain how to solve the problem

- The probability of an event is the measure of the chance that the

event will occur

- The probability of an event A is the number of ways that event A can

occur divided by the total number of possible outcomes

- If P(A) is the probability of event A, is the probability that the event A

does not occur is 1 - P(A)

* Lets solve the problem

- An HR director numbered employees 1 through 50 for an extra

vacation day contest

∴ There are 50 employees

- The HR director will select an employee

- We need to find the probability of select an employees who is not

multiple of 13

* At first lets find the multiples of 13

∵ 13 × 1 = 13

∵ 13 × 2 = 26

∵ 13 × 3 = 39

∴ The multiples of 13 from 1 to 50 are 13 , 26 , 39

∵ There are 3 multiples of 13

∵ There are 50 numbers

∵ Probability of multiple of 13 = $\frac{3}{50}$

∵ Probability of not multiple of 13 = 1 - P(multiple of 13)

∴ Probability of not multiple of 13 = $1-\frac{3}{50}$

∴ Probability of not multiple of 13 = $\frac{47}{50}$

* The probability that the HR director will select an employee who is

not a multiple of 13 is $\frac{47}{50}$

Use the properties of exponential and logarithmic functions to solve each system. Check your answers.

The solved logarithmic function is 2x - y = e and x + y = 8 for log (2x - y) = 1 and log (x + y) = 3 log 2 respectively.

What is a logarithmic and exponential function?

Logarithmic functions and exponential functions are inverses of each other. The logarithmic function is denoted by using the word log while exponential by using the alphabet, e. For example log 10 = 1 and e^2.

Solving the given expressions: log (2x - y) = 1 and log (x + y) = 3 log 2

Applying given properties of logarithmic and exponential function;

log a + log b = log (ab)

4 log x = log x⁴

e^(log x) = 1

e^(x + y) = (e^x) × (e^y)

Take expression, log (2x - y) = 1

Applying exponential on both sides, we get,

e^(log 2x - y) = e^1

2x - y = e

To Check Results,

Taking logarithm both sides,

log (2x - y) = log e

log (2x - y) = 1

Thus, the answer is verified.

Take expression, log (x + y) = 3 log 2

Applying exponential on both sides, we get,

e^(log (x + y) = e^(3 log 2)

x + y = e^(log 8)

x + y = 8

To Check Results,

Taking logarithm both sides,

log (x + y) = log 8

log (x + y) = 3 log 2

Thus, the answer is verified.

Hence, the solved expression is 2x - y = e and x + y = 8 for log (2x - y) = 1 and log (x + y) = 3 log 2 respectively.
