The population of Greene country in 2015 was 51408 which is greater than the population of Orange country in 2015.

The definition of an exponential function is given by the equation

y = aeᵇˣ, where a and b are constants.

The given function is f(x) = 87000(0.9)ˣ.

Given that x = 0 represents the year 2010.

Therefore, x= 5 represents the year 2015.

Substitute x = 5 into the given function:

f(5) = 87000(0.9)⁵

     ≈ 51373

Hence, the population of Orange country is about 51373 in 2015.

Now, the population of Greene country was 78000 in 2010 and has decreased exponentially at a rate of 8% each year.

The population of Greene city after 5 years is given by:

78000(1-8%)⁵

= 78000(1 - 0.08)⁵

= 78000(0.92)⁵

= 51408

Therefore, the population of Greene country in 2015 was 51408 which is greater than the population of Orange country in 2015.

for a chis-square goodness of fit test, if the number of categories is 6 and the test statistics is 8.4345, p value will be pchisq(8.4345,5)

To test a hypothesis' validity against actual data, a statistical calculation called a p-value is used. The probability of experiencing the results that were observed is calculated using a p-value, assuming that the null hypothesis is true. The p-value can be calculated by looking up the 8.4345 value in the Chi-Square distribution table with 5 degrees of freedom (6-1=5).

If $10,000 is invested at x percent simple annual interest for n years, the total amount of interest would be F = 10,000n(x/100)

Simple interest is a quick and straightforward technique to compute interest on money. In the simple interest method, interest always applies to the initial principle amount, with the same rate of interest for each time cycle. When we put our money in a bank, we receive x percent simple annual interest on it. Banks charge many kinds of interest, one of which is simple interest. Now, before delving further into the idea of simple interest, let's first define what a loan is.

A loan is an amount borrowed by a person from a bank or other financial institution to meet their requirements. Home loans, auto loans, student loans, and consumer lending were just few examples of loans.

How to solve?

F = P(1+rt), where Future value is F, Present value is P, Rate is R, Time is t

F = 10,000(1+xn)

F = 10,000(xn)

F = 10,000(n * x/100)

F = 10,000n(x/100)

The answer is (3a + 20) and also here variable ' a ' appears only once.

A linear expression is an algebraic expression in which each term is a constant or a variable raised to the first power. To put it another way, none of the exponents can be greater than 1.

[tex]x^2[/tex] is a variable raised to the second power, whereas x is a variable raised to the first power.

A linear expression is 2x - y + 3.

A constant is represented by the number,  example 5.

Given,

expression (a - 4) and (4a + 16)

subtracting (a - 4) from (4a + 16), results in

What do you mean by probability?

The area of mathematics known as probability deals with numerical representations of the likelihood that an event will occur or that a statement is true. An event's probability is a number between 0 and 1, where, roughly speaking, 0 denotes the event's impossibility and 1 denotes certainty.

According to data in the given question,

We have the given information:

Mean = 44

deviation = 5

Let X be the random variable that represents the population's average number of motorcycle kilometers; in this instance, we know the distribution for X is provided by:

X ~ N(44.5)

Where μ=44 and σ=5,

We are interested on this probability,

P(X>50)

We can also apply the z score formula from:

z=x-μ/σ

Using this formula, we obtained:

P(X>50) = P(X-μ/σ > 50-μ/σ) = P(Z > 50-44/5) = P(z > 1.2)

Using the normal standard distribution and the complement rule, we can determine this probability, giving us:

P (z > 1.2) = 1 - P(z > 1.2) = 1 - 0.8849 = 0.1151

Therefore, the probability is 0.1151.

The first four terms of the given sequence A(n)=4n^3+2 is 6, 34, 110, 258.

In the given question, the nth term of a sequence is given.

We have to write the first four terms of the sequence and we also have to express the terms in simplified form when applicable.

The given sequence is:

A(n)=4n^3+2

We find the four terms of the given sequence by putting n=1,2,3,4 in the given sequence.

Now putting n=1 in the given sequence

A(1)=4(1)^3+2

A(1)=4*1+2

A(1)=4+2

A(1)=6

Now putting n=2 in the given sequence

A(2)=4(2)^3+2

A(2)=4*8+2

A(2)=32+2

A(2)=34

Now putting n=1 in the given sequence

A(3)=4(3)^3+2

A(3)=4*27+2

A(3)=108+2

A(3)=110

Now putting n=1 in the given sequence

Phil's final debt after 20 years will be around $320,679.

To purchase a home, Phil borrowed $150,000 from a bank at a 3.5% annual interest rate.

The annual compounding of interest causes the amount of interest for each year to rise in proportion to the debt. Phil will be required to pay the initial sum plus interest after the first year, which comes to

$150,000 + 3.5% of $150,000 = $155,250.

Since interest is charged on the new amount owed for the second year, Phil will owe

$155,250 + 3.5% of $155,250, which

= $160,551.75.

For the next 20 years, this procedure is repeated, with the amount owed rising yearly by the sum of the year before plus interest. Phil's debt after 20 years will be around $320,679.

The graph the system of linear equations on a coordinate plane is added as an attachment and the solution is (2, 2)

A system of linear equations is a collection of at least two linear equations.

In this case, the system of equations is given as

y=-1/2x+3 and y=2x-2

Rewrite the equations in the system of equations as follows:

So, we have the following representation

y = -1/2x + 3

y = 2x - 2

Next, we plot the graph of the system of equations

See attachment for the graph of the system of equations

In this case, the point of intersection of the equations represent the solution to the system

From the graph, the lines intersect at (2, 2)

This means that the solution to the system of equations is (2, 2)

Recall that

y = -1/2x + 3

y = 2x - 2

Solution = (2, 2)

So, we have

2 = -1/2 x 2 + 3 = 2 --- true

2 = 2 x 2 - 2 = 2 --- true

Let p represents paddling speed of kayack guide  and c represents speed of current.

If paddling downstream, the total speed is p + c because you’re paddling with the current. Similarly, if paddling upstream, the total speed is p - c because you would be paddling against the current.

Since paddling downstream took  2 hours so distance covered 2*(p + c)

which is equal to 20 miles.

2*(p + c) =20.

p + c = 10. -----i

Paddling upstream took 4 hours so distance covered 4*(p-c).

The graph of the new function compared to the first one will be shifted down.

Vertical translation describes the movement of a function graph upward or below. The function's form is preserved in this case. The graph moving or shifting along the y-axis is another name for it. Each point on the graph moves k units vertically during vertical translation, and the graph is said to have translated k units.

The two functions are

f(x) = x + 2

g(x) = x - 1

You can see that all you need to do to transform f into g is just take 3 off of it.

f(x) - 3 = (x+2) - 3

= x + 2 - 3

= x - 1

= g(x)

Every transformation, such as f(x) f(x) + k, now produces a vertical translation, which is translated upward if k > 0 and downward if k 0. The correct response is C since the function is translated three units down in our situation where k = -3.
