A standard six-sided die is rolled $6$ times. You are told that among the rolls, there was one $1,$ two $2$'s, and three $3$'s.

Alex777 [14]

Answer:

$Sequence = 120$

Step-by-step explanation:

Given

6 rolls of a die;

Required

Determine the possible sequence of rolls

From the question, we understand that there were three possible outcomes when the die was rolled;

The outcomes are either of the following faces: 1, 2 and 3

Total Number of rolls = 6

Possible number of outcomes = 3

The possible sequence of rolls is then calculated by dividing the factorial of the above parameters as follows;

$Sequence = \frac{6!}{3!}$

$Sequence = \frac{6 * 5 * 4* 3!}{3!}$

$Sequence = 6 * 5 * 4$

$Sequence = 120$

Hence, there are 120 possible sequence.

During a biology course, Jacobi learned that the diameter of red blood cells can be written as 6.5x10 to the -3 power millimeter

madreJ [45]

Answer:

$\bold{0.0065}$

Step-by-step explanation:

Hi there!

Let's convert numbers in scientific notation to standard form.

$\bold{6.5x10^{-3} }$ => scientific notation

First, the coefficient is $\bold{6.5}$ .

So, we know part of our number.

Now, let's look at the exponent:

$\bold{-3}$

First of all, the exponent is $\bold{NEGATIVE}$ .

This means that we'll move the decimal point to the $\bold{left}$ .

Then, the 3 means we'll move the decimal point 3 units.

So, our number looks like so:

$\bold{0.0065}$

Hope it helps! Enjoy your day!

Colleen is 15 years from retiring. She opens an account at the Savings Bank. She plans to deposit

gulaghasi [49]

9514 1404 393

Answer:

a) $169,234.59

b) $19,234.59

Step-by-step explanation:

The first question you must answer is whether Colleen will earn interest on her first deposit in the first year. That is, does she deposit the money at the first of the year or the end of the year?

The usual "annuity" formula assumes the deposit is at the end of the year, so no interest at all is earned on the last deposit made. If the deposit is at the first of the year, an "annuity due" formula is used, that multiplies the entire ending account value by the annual multiplier, 1.017 in this case.

a) Assuming an "annuity", the formula is ...

A = P((1 +r)^t -1)/r . . . . . for annual compounding at rate r for t years

A = $10,000(1.017^15 -1)/0.017 = $169,234.59 . . . . ending balance

b) Colleen has made 15 deposits of $10,000, for a total of $150,000, so the amount of interest earned is ...

$169,234.59 -150,000 = $19,234.59 . . . . interest earned
