The number of years that Reema took the loan will be 8 years.

A loan or deposit's interest is computed using the starting principle and the interest payments from the ago decade as compound interest.

We know that the compound interest is given as

A = P(1 + r)ⁿ

Where A is the amount, P is the initial amount, r is the rate of interest, and n is the number of years.

Reema took out a 10,000 loan at a 10% annual interest rate. Over the course of the loan, she paid a total of 21,200 in interest.

Then the number of years is calculated as,

21,200 = 10,000 × (1 + 0.10)ⁿ

2.12 = (1.10)ⁿ

Take log on both sides, then we have

log 2.12 = n log (1.10)

n = 7.8839

n ≅ 8 years

The number of years that Reema took the loan will be 8 years.

The difference between classical and empirical probability is C. The empirical method obtains an approximate empirical probability of an event by conducting a probability experiment. The classical method of computing probabilities does not require that a probability experiment actually be performed. Rather, it relies on counting techniques, and requires equally likely outcomes. The classical method obtains an approximate em be performed. Rather, it relies on counting techniques, and requires equally likely outcomes.

Classical probability is based on the idea of equally likely outcomes. In classical probability, the probability of an event is determined by counting the number of favorable outcomes and dividing by the total number of possible outcomes.

Empirical probability, on the other hand, is determined by observing the frequency of an event over a period of time or a number of trials. It's based on the relative frequencies of the outcomes of an experiment.

7-grade angle is an acute angle, which is an angle that measures between 0 and 90 degrees

In a right triangle, the 7-grade angle would be the angle opposite the side that is 7 units long. It is also known as the "opposite angle" because it is opposite to the side of the triangle that is 7 units long.

To calculate the angle,

you first need to know the length of the other two sides of the triangle. Using the Pythagorean theorem, we can calculate the length of the third side. Once you have all three side lengths, you can use the Law of Cosines to calculate the 7-grade angle.

The Law of Cosines states that a2 = b2 + c2 – 2bc cos A, where a is the side opposite the angle A, b is the adjacent side, and c is the hypotenuse. The Law of Cosines can be rearranged to solve for angle A.

For example, if we have a triangle with side lengths of 7, 8, and 10, then the angle opposite the side of length 7 would be 41.8 degrees.

On solving the provided question, we can say that - the value of the simple interest will be $ 14432.

Multiplying the principal by the interest rate, time, and other factors yields simple interest. Simple return equals principle times interest times hours is the marketed formula. It is easiest to compute interest using this formula. A percentage of the principle balance is how interest is most commonly computed. For instance, he will only pay his portion of the 100% interest if he borrows $100 from a buddy and promises to pay it back with 5% interest. $100 (0.05) = $5. When you borrow money, you must pay interest, and when you lend money, you must charge interest. Most of the time, interest is expressed as a yearly percentage of the loan amount. The interest rate on the loan is known as this percentage.

here,

we have P = 41000; R = 4.4 ; T = 8

An equation for the number of bacteria, B, in terms of the number of hours, t, since the experiment began is [tex]B = 100e^{{(t/15)}}[/tex].

The width of the single slit is 0.00135 mm and the second minimum will be at angle of 69.9º.

To find the width of the single slit, we can use the formula:

w = λL/d * sinθ

where w is the width of the single slit, λ is the wavelength of light, L is the distance from the slit to the screen, d is the distance between the slits and θ is the angle at which the first minimum is observed. By substituting the given values, we get:

w = (633*10^-9 m) (2L) / (d) * sin(28.0º) = 0.00135 mm

The angle of the second minimum can be found by using the formula: θn = sin^-1(nλ/w)

where θn is the angle at which the nth minimum is observed, n is the order of the minimum and λ and w are the wavelength and width of the single slit respectively. Substituting the values we get: θ = sin^-1(2*(633*10^-9 m) / (0.0175 mm)) = 69.9º

It is important to note that the above explanation is based on the assumption that the width of the single slit is much smaller than the distance between the slit and the screen (L) and the distance between the slits (d).

The probability of a or b will be equal to 0.30769.

What is probability?

Probability is defined as the ratio of the number of favorable outcomes to the total number of outcomes in other words the probability is the number that shows the happening of the event.

The probability of the total sample points in A U B is P(A U B). The probabilities of sample points in A and B are now added together as P(A) + P(B). To get the total of probabilities in (A U B), which is P, we need to subtract once because we added the sample points in (A B) twice (A U B).

Given that p(a)=0.07692, p(b)=0.25, and probability of a and b. =0.01923. The probability will be calculated by using the formula below:-

P(A) = 0.07692

P(B)=0.25

P(AB) = 0.01923

P(AUB) = P(A) + P(B) - P(AB)

P(AUB) = 0.07692 + 0.25 - 0.01923

P(AUB) = 0.30769

A rectangular prism is a three-dimensional geometric shape that has six rectangular faces. It has three pairs of parallel faces, with each pair being a rectangle of the same size and shape. The opposite faces of a rectangular prism are also parallel and congruent. It is also known as a cuboid. In addition to having three pairs of parallel, congruent rectangle faces, a rectangular prism also has three pairs of parallel edges and four pairs of congruent vertices. It can also be defined by its length, width, and height, which are the measurements of the three rectangular faces.

The surface area of a three-dimensional object is the total area of all of its faces or surfaces. It is the sum of the areas of all the faces of an object. For example, the surface area of a rectangular prism is the sum of the areas of all six of its rectangular faces. To find the surface area, you would add up the area of the length x width of each face. In a rectangular prism, the surface area can be calculated by:

Surface Area = 2lw + 2lh + 2wh

Where l is the length, w is the width and h is the height.

Surface Area = 2lw + 2lh + 2wh
