Answer:

20

Step-by-step explanation:

if you divide 50 from 2.5 you get 20

then take 20x2.5 and you get 50.

The person will gain Rs. 5,500 after 3 years by lending the whole amount to a shopkeeper at the same rate of compound Interest for the same time.

Given, Principal amount (P) = Rs. 16,000

Rate of Interest (R) = 12.5%

Time (T) = 3 years(a)

The amount to be paid to the bank as simple interest can be calculated as follows:

Simple Interest (SI) = (P × R × T) / 100= (16000 × 12.5 × 3) / 100= Rs. 6,000Therefore, the amount to be paid to the bank as simple interest is Rs. 6,000.

(b) The amount to be received by the person from the shopkeeper as compound interest can be calculated as follows: Compound Interest (CI) = P × [1 + (R/100)]T – P= 16000 × [1 + (12.5/100)]3 – 16000= Rs. 21,500

Therefore, the amount to be received by the person from the shopkeeper as compound interest is Rs. 21,500.(c) Gain = CI - P= 21500 - 16000= Rs. 5,500

Therefore, the person will gain Rs. 5,500 after 3 years by lending the whole amount to a shopkeeper at the same rate of compound interest for the same time.

Answer:

146°

Step-by-step explanation:

The measure of the arc EF is equal to the angle subtended at the centre.

That is EF = 146°

Using the .01 level of significance means that, in the long run, a Type I error occurs 1 time in 100. This means that if we perform a statistical test 100 times, and we set the level of significance at .01, then we can expect to observe one false positive result due to chance alone. So, the correct option is 1).

A Type I error occurs when we reject a true null hypothesis, or when we conclude that there is a significant difference or relationship between two variables when in fact there is not.

By setting the level of significance at .01, we are minimizing the risk of making a Type I error while increasing the risk of making a Type II error, which occurs when we fail to reject a false null hypothesis. So, the correct answer is 1).

ohhhhhhhhhhhhhhhh.......

The value of the probability represented by P(Take the bus | Sophomore) is 0.83

Conditional probabilities are probabilities that only occurred because an event has already occurred i.e. they are dependent on the initial event

From the table of values in the question, we have the following parameters:

The required probability represented by P(Take the bus | Sophomore ) = [?] is then calculated as:

P(Take the bus | Sophomore) = Number of students that (Take the bus and Sophomore) divided by Number of students that are (Sophomore)

Substitute the known values in the above equation

P(Take the bus | Sophomore) = 25/(2 + 25 + 3)

Evaluate the sum in the denominator

P(Take the bus | Sophomore) = 25/30

Evaluate the above quotient

P(Take the bus | Sophomore) = 0.83

Hence, the value of the probability represented by P(Take the bus | Sophomore) is 0.83

a. The upper bound on the probability that the center will recycle more than 55,000 cans on a particular day is 90.9%.

b. Chebyshev’s inequality does not provide a useful lower bound on the probability that the center will recycle 40,000 to 60,000 cans on a certain day

a) Markov’s inequality states that for a non-negative random variable X and any constant c > 0, the probability that X is greater than or equal to c is at most the expected value of X divided by c. Mathematically, we have:

P(X >= c) <= E(X) / c

In this case, X is the number of tin cans recycled in a day, and c = 55,000. The expected value of X is 50,000 cans, so we can apply Markov’s inequality:

P(X >= 55,000) <= E(X) / 55,000 = 50,000 / 55,000 = 0.909 or 90.9%

b) Chebyshev’s inequality states that for any random variable X with finite mean mu and variance sigma^2, the probability that X deviates from its mean by some number k standard deviations is at most 1/k^2. Mathematically, we have:

P(|X - mu| >= k sigma) <= 1 / k^2

In this case, mu = 50,000 and sigma^2 = 10,000, so sigma = sqrt(10,000) = 100. We want to find a lower bound on the probability that the center will recycle between 40,000 and 60,000 cans, which is the same as finding an upper bound on the probability that X deviates from its mean by more than 1 standard deviation. Therefore, we set k = 1 in Chebyshev’s inequality:

P(|X - 50,000| >= 100) <= 1 / 1^2 = 1

Therefore, the probability that X deviates from its mean by more than 1 standard deviation is at most 1. This means that the probability that the center will recycle between 40,000 and 60,000 cans is at least:

1 - P(|X - 50,000| >= 100) >= 1 - 1 = 0 or 0%

since it only guarantees that the probability is not zero, but gives us no information about how close to zero it actually is.

Answer:

Step-by-step explanation:

Two linear equations in two variables can be solved using the substitution techniques, graphical method or by the elimination method.

Let us consider any two real world linear equations in two variables.

x - y = 0

x + y = 4

Now let us first solve them by substitution method:

equation 1 can be written as : x = y ,

Now we substitute this value of x in the second equation:

x + y = 4

or,  y + y = 4

or, 2y = 4

or, y = 2

At x = 2 , y = 2. Hence the solution is (2,2)

Now let us solve by elimination method:

adding equation 1 and 2 we get:

x - y = 0

x + y = 4

2x = 4

or, x =2

at x=2 , y = 4-2 =2 Hence the solution is (2,2)

Now we will solve the equations graphical method.

In the graph attached below we can clearly see that the straight line representation of the two equations intersect at the point (2,2)

Hence the solution is (2,2) .

Therefore any linear equation in 2 variables can be solved by substitution , elimination and graphically.

Answer:

\((a)\ Area = \pi (6-x)^2\)

(b) 4 times

Step-by-step explanation:

The question is illustrated with the attached figure

Solving (a): The area of the pupil

First, we need to calculate the radius (r) of the pupil.

Since the smaller circle is the pupil, then

\(r = 6 - x\)

Area is then calculated as:

\(Area = \pi r^2\)

\(Area = \pi (6-x)^2\)

Solving (a): The area of the pupil

First, we need to calculate the radius (r) of the pupil.

Since the smaller circle is the pupil, then

\(r = 6 - x\)

Area is then calculated as:

\(Area = \pi r^2\)

\(Area = \pi (6-x)^2\)

Solving (b): How many times greater is the area of the pupil, if x decreases from 4 to 2

Initially,

\(x = 4\)

So, the area of the pupil is:

\(Area = \pi (6-x)^2\)

\(Area = \pi(6 - 4)^2\)

\(Area = \pi(2)^2\)

\(Area = 4\pi\)

When x reduces to 2, the area of the pupil is:

\(Area = \pi (6-x)^2\)

\(Area = \pi (6-2)^2\)

\(Area = \pi (4)^2\)

\(Area = 16\pi\)

Calculate the ratio (r) of both areas:

\(r = \frac{16\pi}{4\pi}\)

\(r = 4\)

Hence, it is 4 times greater

We want to answer different things regarding circles, we will see that the area of the pupil is:

A = pi*(6mm -x)^2

And that the area of the pupil is 4 times larger after entering the dark room.

We know that the radius of the pupil is R = 6mm - x

The area of the pupil is given by:

A = pi*(6mm - x)^2

This is the polynomial we wanted.

Now we know that the width of the iris decreases from 4mm to 2mm when you enter a dark place, so x goes from 4mm to 2mm, then the two areas are:

The quotient between the areas is:

A'/A = (50.24 mm^2)/(12.56 mm^2) = 4

So the area of the pupil is 4 times larger after entering the room than before entering the room.
