Step-by-step explanation:

The researchers came up with this number by making a model with specific coins to determine the difficulty, in terms of the probability of getting this coin.

The researchers Shiyoung Lu and Steven Skiena wanted to know how probable it was to collect a complete set of pennies since 1959 until 1997. By the end of this study, they decided at least 684 coins must be collected to complete this mission.

Firstly, they analyze the probability for getting one coin. From this, it was concluded the probabillity was lower for old coins. After this, they used the data collected from all the coins and created an equation. This equation or model led them to conclude the answer was 684 coins.

A combination is a mathematical technique that determines the number of possible arrangements in a collection of items where the order of the selection does not matter.

From the given information:

The library has 28 science fiction books. Each shelf holds 5 books

Then

apply the combination,

Then

C(n,r) = C(28,5)

after solving it become

C(28,5) = 28! /(5!(28-5)!)

And

C(28,5) = 28! /(5!(23)!)

Then after rearranging the terms and solving the value becomes

The formula that correctly solves for C is D. C = 5/9 (F - 32)

In mathematics, an equation is a formula that expresses the equality of two expressions by connecting them with the equal sign = .

The given formula is,

F = 9/5C + 32

where Celsius is C, and degrees Fahrenheit is F

To solve for C let us isolate C to the one side and other terms to the other,

9/5 C = F - 32

Multiplying both side by 5/9 we get,

9/5 C *5/9 = 5/9* (F - 32)

or, C = 5/9 (F - 32)

which is the formula for C.

Thus, the formula that correctly solves for C is D. C = 5/9 (F - 32)

The solution for the unknown variable in I = PRT where I = 2160, P =24000 and R = 0.03 is 3

The given parameters are

I = PRT

Where

I = 2160, P =24000 and R = 0.03

Substitute I = 2160, P =24000 and R = 0.03 in the above equation I = PRT

2160 = 24000 * 0.03 * T

Evaluate the product

So, we have

2160 = 720 * T

Divide both sides by 720

T = 3

The population of the Bownville city reach 1,548,800 at nearly 2015

Given, Since January 2000,

The population of the city of Brownville has grown according to the mathematical model.

Y= 720,500(1.022) x

Where, X= number of years

To find:  If this continues, predict the year during which population of Brownville will reach 1,548,800

Starting population = 720,500

Growth rate = 1.022

(720500) (1.022) x = 1,548,800

1.022x = 2.1496

Taking log on both sides

log1.022x = log2.1496

x log 1.022 = log 2.1496

x=log 1.022×2.1496

x=15

Therefore, nearly it takes 15 years to reach the population 1,548,800

Hence the population of the Bownville city reach 1,548,800 at nearly 2015.

The interest earned on even a $30,000 deposit compounded monthly at 1% is $15150.75.

Compound interest is applied when the principal amount changes after the specified time period.

For example, if you give someone $500 at a 10% yearly interest rate, $500 is your principal amount. After one year, the interest will be $50, and the principle amount will indeed be $550; therefore, the interest for the following year will be $550, not $500.

P = P₀e^rt where r represents the annual interest rate as well as t represents the time period in years.

So,

P₀ = 30000

r = 1% = 0.01

t = 6 months = 0.5 year

So,

P = 30000e^0.01(0.5)

P = 30000 × 1.5050250835

P = $45150.752505

So, interest

I =45150.752505- 30000 = $15150.75

The interest earned on even a $30,000 deposit over six months at 1% compounded daily is $15150.75

Answer:

x = 19

Step-by-step explanation:

The two angles shown here are congruent, so we will set them equal to each other. We will solve for x in the equation:

4x + 18 = 6x - 20

Subtract 4x from both sides:

18 = 2x - 20

Add 20 to both sides:

38 = 2x

Divide by 2 on both sides:

1.111 liters of water must be added to 5 kilograms of soil.

According to the statement, water percentage is equal to the ratio of water mass divided by the total mass of water and dust and multiplied by 100. Then, the initial and final percentages are defined below:

Initial percentage

y / 5 = 0.12                              (1)

Final percentage

(y + x) / (5 + x) = 0.28             (2)

Then, we need to resolve the resulting system of linear equations:

y = 0.6                  (1)

y + x = 1.4 + 0.28 · x

0.72 · x = 1.4 - y

x = 1.944 - 1.389 · y

x = 1.111

We need to add 1.111 kilograms of water. If the density of a kilogram per liter, the volume required in liters is:

Thus, the kinetic energy of an object is directly proportional to its mass; thus, doubling the mass doubles the kinetic energy.

In, the given case, the paint contained in the two buckets are combined.

Thus, the mass is remained constant.
