Answer:

In 50 years Population is 96000 people.

Step-by-step explanation:

Let population be x

In the first 10 years

Population becomes 2x

In 20 years it becomes 4x

In 10n years it becomes 2^n x

Therefore

for n= 5

x = 3000

Population is 2⁵ (3000)

= 32(3000)

= 96000

Population becomes 96000

Hope it helps...

Jessica has 48 coins, some of them are nickels and some are dimes. How many of each does she have if she has $3.25 total? 69 POI

Mrrafil [7]

<u>Answer:</u>

Nickels = 44.6

Dimes = 3.4

<u>Step-by-step explanation:</u>

We know that Jessica has 48 coins of which some are nickels and some are dimes so we can write it as:

n = amount of nickels

d = amount of dimes

$n+d=48$ --- (1)

We are to find the number of nickels and dimes if their total worth is $3.25.

Since a dime is worth 10¢ and a nickel is 5¢, so it should be:

$0.05n + 0.3d = 3.25$ --- (2)

From (1):

$n=48-d$

Substituting this value of $n$ in (2) to get:

$0.05(48-d) + 0.3d = 3.25$

$2.4-0.05d+0.3d=3.25$

$2.4+0.25d=3.25$

$0.25d=0.85$

$d=3.4$

Finding $n$ by substituting the value of $d$ :

$n=48-d$

$n=48-3.4$

$n=44.6$

4.4.3 Quiz: Independence

lbvjy [14]

Answer:

$\frac{2}{15}$

Step-by-step explanation:

<h2><u>Lesson : Probability</u></h2><h2><u></u></h2>

We have a bag with 4 white chips and 6 black chips
Question : What is the probability of randomly choosing a white chip, not replacing it, and then randomly choosing another white chip?

4 white and 6 black

4 + 6 = 10

Choosing the first white chip : $\frac{2}{5}$

Since we took one out , now

3 white chips , 6 black chips

3 + 6 = 9

Choosing another white chip : $\frac{1}{3}$

$\frac{2}{5} * \frac{1}{3}$

$\frac{2}{15}$
