The annual salaries of employees in a large company are approximately normally distributed with a mean of $50,000 and a standard
Lena [83]

Answer:

The probability of randomly selecting one employee who earned less than or equal to $45,000=0.00621

Step-by-step explanation:

We are given that

Mean,\mu=50000

Standard deviation,\sigma=2000

We have to find the probability of randomly selecting one employee who earned less than or equal to $45,000.

P(x\leq 45000)=P(\frac{x-\mu}{\sigma}\leq \frac{45000-50000}{2000})

P(x\leq 45000)=P(Z\leq-\frac{5000}{2000})

P(x\leq 45000)=P(Z\leq -2.5)

P(x\leq 45000)=0.00621

Hence,  the probability of randomly selecting one employee who earned less than or equal to $45,000=0.00621

How can you quickly calculate 20 percent of any bill amount?
Tems11 [23]
First, convert the percent into a decimal. To do this, simply more the % sign two places to the left and make it into a decimal point.

20% = 0.20

Then we will let x be our bill amount.

Then multiply 0.20 and x together to get your answer.

So, 0.20 * x is your answer.
