Arte-miy333 [17]

Answer:

On the sixth day (10 - 4), the worm was 2.5mm long.

Step-by-step explanation:

Giving the following information:

Future Value= 40mm

Present Value= 2.5mm

Number of periods (n)= ?

Growth rate= 100% per day

<u>First, we need to calculate the number of days it will take to grow from 2.5mm (PV) to 40mm (FV):</u>

<u></u>

n= ln(FV/PV) / ln(1+i)

n= ln (40 / 2.5) / ln (2)

n= 4

It will take 4 days.

On the sixth day (10 - 4), the worm was 2.5mm long.

There are 16 possible outcomes.

Step-by-step explanation:

For this question, we combine the possibilities together.

R = red G = green O = orange B = blue

There are 16 possible outcomes.

You can also find the total number of possible outcomes by using the formula for permutations. n is the total number of choices. r is the number you are examining.

$\frac{n!}{(n-r)!}$

$\frac{4!}{(4-2)!} =12$

This number doesn't include the outcome of having the same color twice. There are four colors meaning that their four outcomes in which the same color is spun twice.

12 + 4 = 16
