The compound interest is ₹46,148.68 and the total amount after 4 years and 6 months is ₹1,46,148.68.

The formula to calculate compound interest is:

A = P * (1 + r/n)^(nt)

Where:

A is the total amount after t years

P is the principal amount

r is the interest rate per annum

n is the number of times the interest is compounded per year

t is the number of years

In this case:

P = ₹1,00,000

r = 10% per annum = 0.10

n = 1 (since the interest is compounded annually)

t = 4 years and 6 months = 4.5 years

A = ₹1,00,000 * (1 + 0.10/1)^(1 * 4.5) = ₹1,00,000 * 1.461486788

A = ₹1,46,148.68

What is Probability ?

Probability can be defined as ratio of number of favourable outcomes and total number of outcomes.

Let's call the total number of students "n".

Then:

n - 5 students liked either blue or green or both,

12 students liked both blue and green,

17 - 12 = 5 students  liked only blue,

16 - 12 = 4 students liked only green.

So:

n - 5 = 5 + 4 + 12

n = 26

There were 26 students in the class.

Therefore, The number of students were in the class is 26

There are 7 people in Mr. Wilson's class, as Zach is the second person and Mary is the seventh person.

To calculate the total number of people in the class, we can use the formula 2x = 7, where x is the total number of people. Solving for x, we get x = 7.

To determine the number of people in Mr. Wilson's class, we can use the formula for the number of people in a circle, which is N = 2(n-1), where n is the number of people standing opposite each other in the circle. In this case, n is 2 (Zach and Mary). Therefore, N = 2(2-1) = 2 people. However, since there are 7 people in total in the circle, we can conclude that the number of people in Mr. Wilson's class is 7. To explain further, based on the given information, we can say that Zach is the second person, which means there are 2 people before him in the circle. Therefore, there are 7 people in Mr. Wilson's class. To further explain, we can break down the equation as follows: The person opposite of Zach is the seventh person, or 7th, so we can say that 7 is equal to the number of people in the class multiplied by 2, or 2x. Then, solving for x, we get x = 7. This means that the total number of people in the class is 7.

The correlation between two variables is an important measure that helps us understand the relationship between them. In Scenario 3-2, if the heart disease death rate is expressed as deaths per 1,000 people instead of as deaths per 100,000 people, it would not change the correlation (r) between wine consumption and heart disease death rate.

The correlation coefficient (r) measures the strength and direction of the relationship between two variables. If the heart disease death rate is expressed as deaths per 1,000 people instead of as deaths per 100,000 people, it would change the units in which the death rate is expressed, but it would not change the underlying relationship between wine consumption and heart disease death rate.

In other words, regardless of the units in which the death rate is expressed, the correlation between wine consumption and heart disease death rate would remain the same. This is because the correlation measures the relationship between two variables, not the units in which they are expressed. It is important to note that expressing the death rate in different units may make it easier or more difficult to understand the relationship between two variables, but it does not change the underlying correlation.

In conclusion, the correlation (r) between wine consumption and heart disease death rate would not change if the death rate were expressed as deaths per 1,000 people instead of as deaths per 100,000 people.

By making exponential function y=12500(1.07)^t, the value of the painting in 10 years will be $24589.

What are exponential functions?

An exponential function is a Mathematical function in the form f (x) = a^x, where “x” is a variable and “a” is a constant which is called the base of the function and it should be greater than 0. The most commonly used exponential function base is the transcendental number e, which is approximately equal to 2.71828.

Now,

Initial value=$12500

Rate = 7% increase every year

so, we can make a function for the increment in value

y=12500(1+7/100)^t   where t=time in years

y=12500*1.07^t

for t=10

y=1250081.07^10

y=$24589

Ben's probability to pass is 0,8
to make it simpler for you to understand I'm going to use percentages.

We can transform 0,8 in a fraction so 8/10 and amplify it by 10 so 80/100
so the percentage showing that Ben will pass is 80% to find out the percentage that Ben will fail we subtract 80% from 100% which results in 20%

so the probability that Ben will fail is 0,2
and Tom's probability to fail is 0,3


To find out the answer to b) we need to understand how we calculate it.

Take as an example a dice. A dice has 6 faces and you need 1 side to get out of jail (let's say you need a 6). Your probability to get that side is 1/6

But what if you have two dice and you need both to be 6? Well in that case it'll be 1/6 x 1/6 which is 1/36

So, to find out the probability of both passing, we have to do 8/10 x 7/10 which is 56/100 and it's equal to 0,56. And you might wonder why the probability both will pass seems bigger than their probability to pass. Well 0,8 actually can mean 0,800000... and so on but it's easier to just let it as 0,8

For c) the probability that only one will pass is: 0.12

We first need to find the probability both fail
100% - 56% = 44%

and we subtract 44% from 56% which is equal to 12% or 0.12

The value of x in the equation is x = -1 and x = -4.67

From the question, we have the following parameters that can be used in our computation:

3x^2 + 13x + 4 = 0

This is a quadratic equation that can be solved using the quadratic formula:

x = (-b ± √(b² - 4ac)) / 2a

where a = 3, b = 13, c = 4

The value of ∫ (x + 1)/(9x² + 6x + 5) dx by partial fractions is 1/18ln(9x² + 6x + 5) + 1/9 (tan^-1 (3x+1)/2)

Given ∫ (x + 1)/(9x² + 6x + 5) dx

Discriminant of is 9x² + 6x + 5 is

                                 D = 6² - 4 x 9 x 5 = - 144 < 0

So, 9x² + 6x + 5 cannot be factorized in rational factors

Observing that differential of 9x² + 6x + 5, let us split (x + 1)/(9x² + 6x + 5) as (18x + 18)/18(9x² + 6x + 5)

or (18x + 6)/18(9x² + 6x + 5) + (12)/18(9x² + 6x + 5)

So, (x + 1)/(9x² + 6x + 5) = (18x + 6)/18(9x² + 6x + 5) + (12)/18(9x² + 6x + 5)

∫ (x + 1)/(9x² + 6x + 5) dx = ∫ (18x + 6)/18(9x² + 6x + 5) dx + ∫ (12)/18(9x² + 6x + 5) dx

= 1/18∫ (18x + 6)/(9x² + 6x + 5) dx + 2/3∫ 1/(9x² + 6x + 5) dx

Let us integrate the first part and assume u = 9x² + 6x + 5

then, du = (18x + 6) dx

So, 1/18∫ (18x + 6)/(9x² + 6x + 5) dx = 1/18∫ 1/u du

                                                         = 1/18 lnu

                                                         = 1/18ln(9x² + 6x + 5)

For second part, 2/3∫ 1/(9x² + 6x + 5) dx, we will use

                     ∫ dx/(x² + a²) = 1/a tan^-1(x/a) +c

For this converting denominator into the sum of two squares, we get

    2/3∫ 1/(9x² + 6x + 5) dx = 2/27∫ 1 / ((x + 1/3)²+(2/3)²) dx

Let us now substitute u = x + 1/3 and as du = dx

so, 2/27∫ 1 / ((u)²+(2/3)²) dx = 2/27 (3/2 tan^-1 (3u/2))

                                            = 1/9 (tan^-1 (3(x+1/3)/2))

                                            = 1/9 (tan^-1 (3x+1)/2)

Hence,∫ (x + 1)/(9x² + 6x + 5) dx = 1/18ln(9x² + 6x + 5) + 1/9 (tan^-1 (3x+1)/2)

The required change in pressure to maintain the flow rate in a pipe with a reducing diameter is ρ * v² / 16.

To maintain a constant flow rate in a pipe with changing diameter, the velocity of the fluid must remain constant. This is known as the principle of continuity, which states that the product of the velocity and the cross-sectional area of a pipe must remain constant.

Given that the diameter of the pipe is reduced from 8 inches to 4 inches, the cross-sectional area of the pipe is also reduced by a factor of 4. Hence, to maintain the same flow rate, the velocity of the fluid must increase by a factor of 4.

Since the fluid is incompressible and Newtonian, the pressure drop can be calculated using the continuity equation and motion equation (Bernoulli's equation).

ΔP = ρ * v²  / 2

where ΔP is the change in pressure, ρ is the density of the fluid, and v is the velocity of the fluid.

Plugging in the values, we get:

ΔP = ρ * (v / 4)² / 2 = ρ * v² / 16

So, the required change in pressure to maintain the flow rate in a pipe with a reducing diameter is ρ * v² / 16.
