The answer is 7.76 x 10^-2 grams

When writing scientific notations (with general form N x 10^a), you convert the given value in such a way that the N would be within 1-10 range, and a would be the number of times you move your decimal places. The sign of a would depend whether you move the decimal place to the left or right.

to the left = positive a
to the right = negative a

7.76 · 10^-5 grams

There are 1000 mg in 1 gram.

Therefore .0776 is divided by 1000 when using dimensional analysis giving .0000776.

Scientific notation requires the digit term to be in between 0 and 10, forcing us to move he decimal place five places right.

We multiply the resulting number by 10^-5 to maintain the number’s original value.

In playing Monopoly, rolling doubles three times in a row sends you to jail. What is the probability of rolling three consecutiv

Alex777 [14]

To find the probability you must multiply the probability of rolling doubles by itself 3 times.

to roll a double of any number you have to have the same number on a six-sided die that can be represented as 1/6 times 1/6 = 1/36 chance per roll

$\frac{1}{36} * \frac{1}{36} * \frac{1}{36} = \frac{1}{46656}$

there is a 1 in 46656 chance in rolling doubles 3 times in a row.
