What is (½)3. ???????

Karolina [17]

It is hard to tell your precise intention. Choose the appropriate interpretation.

$\frac{1}{2} \times 3 = \frac{1 \times 3}{2} = \frac{3}{2} = 1\frac{1}{2}$

$(\frac{1}{2})^{3} = \frac{1^{3}}{2^{3}} = \frac{1}{8}$

The average salary for a teacher is $55,000 per year. A physician makes on average $220,000. If you consider the earning potenti

Evgen [1.6K]

Answer:

The difference between the teacher's earnings as compared to the physician's earning over 30 years is $4,950,000

Step-by-step explanation:

Given as :

The average salary for a teacher in a year = $55,000 per year

The average salary for a physician in a year = $220,000 per year

Let The difference between the teacher's earnings as compared to the physician's earning over 30 years = $x

Now,

The average salary for a teacher for 30 years = $55,000 × 30 = $1,650,000

The average salary for a physician for 30 years = $220,000 × 30 = $6,600,000

So,

The difference between the teacher's earnings as compared to the physician's earning over 30 years = The average salary for a physician for 30 years - The average salary for a teacher for 30 years

Or, $x = $6,600,000 - $1,650,000

∴ x = $4,950,000

So, The difference between the teacher's earnings as compared to the physician's earning over 30 years = x = $4,950,000

Hence, The difference between the teacher's earnings as compared to the physician's earning over 30 years is $4,950,000 . Answer

A number cube is rolled 100 times. A 6 is rolled 40 times. What is the relative frequency for rolling a 6?

horsena [70]

The frequency would be 60%.
You know how many times she rolled the dice (100) then it also tells you the dice rolled 6 40 times. So then we minus 100 by 4. Which will end up getting us 60. Which we can also write as 60%. So the frequency is 60%.
