The fraction is 47/200. The decimal is 0.235.

A percentage can be written in a fraction form by putting 100 on the denominator. For example, the fraction corresponding to x % is x/100.

For converting a percentage into a decimal first it should be converted into fractions as fractions can only be converted into decimal.

For example, the decimal for the fraction 50% is 0.5, which is given by writing 50% as 50/100 = 0.5 after putting decimal on 2 places left to 50.

So here the given percentage is 23.5%.

The corresponding fraction is 23.5/100 = 235/1000 = 47/200 after eliminating the decimal on the numerator and simplifying.

Now the corresponding decimal is, 0.235. Since 1000 is in the denominator for 235/1000, we can simply find the decimal by putting decimal point on 3 places left to 235.

The cost of polishing the floor of the square hall is ₹2343.75

The Side of Square Hall = 12.5 m

The cost of polishing the floor per meter sq. = ₹ 15

We have to find the cost of polishing the floor.

First we will calculate the area of floor of the square hall.

Area of a square is defined as the number of square units needed to fill a square. In general, the area is defined as the region occupied inside the boundary of a flat object or 2d figure. The measurement is done in square units, with the standard unit being square meters (\(m^{2}\)).

Area of square=\((12.5)^2\)

Area of square =\(12.5 \times 12.5\)

Area of square =156.25

The area of the floor of Square Hall is 156.25 \(\mathrm{~m}^2$\)

Per square meter cost of polishing the floor is ₹15,

To find the cost of polishing the floor of the square hall of area 156.25 sq. m, simply multiply 15 by the area of the floor of the square hall.

Therefore, the cost of polishing,

=15×156025

=2343.75

Therefore, the cost of polishing is ₹2343.75.

∫[4, 6] f(x) dx = ∫[4, 6] (18x - 3) dx = [9x^2 - 3x] evaluated from 4 to 6 = (9(6)^2 - 3(6)) - (9(4)^2 - 3(4)).

∫[0, 2] f(x) dx = ∫[0, 2] (18x - 3) dx = [9x^2 - 3x] evaluated from 0 to 2 = (9(2)^2 - 3(2)) - (9(0)^2 - 3(0)).

E(x) = ∫[0, ∞] x f(x) dx = ∫[0, ∞] x(18x - 3) dx = [3x^3 - (3/2)x^2] evaluated from 0 to ∞ = lim(a→∞) [(3a^3 - (3/2)a^2) - (3(0)^3 - (3/2)(0)^2)].

a) To find the probability that the television set lasts between 4 and 6 years, we need to calculate the integral of the density function f(x) over the interval [4, 6]. Since the density function is given by f(x) = 18x - 3 for 0 ≤ x < 3 and 0 for x ≥ 3, we have:

∫[4, 6] f(x) dx = ∫[4, 6] (18x - 3) dx = [9x^2 - 3x] evaluated from 4 to 6 = (9(6)^2 - 3(6)) - (9(4)^2 - 3(4)).

b) To find the probability that the television set lasts at least 5 years, we need to calculate the integral of the density function f(x) over the interval [5, ∞). However, since the density function is zero for x ≥ 3, the integral over this interval is zero.

c) To find the probability that the television set lasts less than 2 years, we need to calculate the integral of the density function f(x) over the interval [0, 2]. Since the density function is given by f(x) = 18x - 3 for 0 ≤ x < 3 and 0 for x ≥ 3, the integral becomes:

∫[0, 2] f(x) dx = ∫[0, 2] (18x - 3) dx = [9x^2 - 3x] evaluated from 0 to 2 = (9(2)^2 - 3(2)) - (9(0)^2 - 3(0)).

d) To find the probability that the television set lasts exactly 4.18 years, we need to evaluate the density function f(x) at x = 4.18. Plugging in the value of x into the density function, we get f(4.18) = 18(4.18) - 3.

e) To find the expected value of the number of years that the television set lasts, we need to calculate the integral of xf(x) over the entire range of x, which is [0, ∞). The expected value is given by:

E(x) = ∫[0, ∞] x f(x) dx = ∫[0, ∞] x(18x - 3) dx = [3x^3 - (3/2)x^2] evaluated from 0 to ∞ = lim(a→∞) [(3a^3 - (3/2)a^2) - (3(0)^3 - (3/2)(0)^2)].

In a nonprobability sampling, not all members of a population have an equal probability of being included.

In a probability sampling, all members of the population have an equal probability of being included.

The strength of the association is described by the effect size.

Curvilinear association is one in which the correlation coefficient is zero (or close to zero) and the relationship between two variables isn't a straight line. False.

In nonprobability sampling, the selection of individuals from the population is not based on random sampling principles. This means that not all members of the population have an equal probability of being included in the sample.

In probability sampling, every member of the population has an equal and known chance of being selected for the sample. Random sampling methods, such as simple random sampling, stratified random sampling, and cluster sampling, are commonly used to achieve this. In probability sampling, the sample is representative of the population, and statistical inferences can be made.

The strength of the association between two variables is typically measured by the effect size. Effect size quantifies the magnitude or magnitude of the relationship between variables and provides an indication of the practical or substantive significance of the association.

Curvilinear association refers to a relationship between two variables that cannot be adequately described by a straight line. In such cases, the correlation coefficient between the variables may be zero or close to zero, indicating no linear relationship.

Nonprobability sampling involves selecting individuals without an equal probability of inclusion, while probability sampling ensures that all members of the population have an equal chance of being included. The strength of the association between variables is described by the effect size, and a curvilinear association indicates a non-straight line relationship between variables.

The maximum likelihood estimate for the bias of the coin is 1/3.

The maximum likelihood estimate for the bias of the coin is the proportion of times it came up heads, which is 10/30 or 1/3.

The idea behind maximum likelihood estimation is to find the value of the parameter (in this case, the bias of the coin) that makes the observed data (in this case, the number of heads and tails) the most likely to occur.

In other words, we want to find the value of the parameter that maximizes the likelihood function.

For a coin flip, the probability of getting heads is p and the probability of getting tails is 1-p. The likelihood function for observing 10 heads and 20 tails is:

\(L(p) = (p)^{10} * (1-p)^{20}\)

To find the maximum likelihood estimate, we take the derivative of the likelihood function with respect to p and set it equal to zero:

\(d/dp [L(p)] = 10*(p)^9*(1-p)^20 - 20*(p)^{10}*(1-p)^{19} = 0\)

Solving for p, we get:

p = 1/3

Therefore, the maximum likelihood estimate for the bias of the coin is 1/3.

Answer: moderate, C, B

Step-by-step explanation:

A)  A shows a moderate negative correlation.  It is moderate because the scattered points are sort of close to the line so it has moderate/medium correlation.  It is also negative because it has a negative slope

B) C shows the strongest correlation because the points around the line are tight and close.

C)  B should not have been drawn.  The  correlation is very weak.  You do know where the line should be because the points are all over the place.

$2.6 million in 2000 dollars is more than what it would have cost to restore the courthouse.

The price index is the average price for a certain class of products or services during a particular time period.

An asset's current cost is determined by multiplying the base year cost by the current year's price index.

It was 2000.

Hospital: $2,635,417 ($500,000 x 126.5 / 24)

Courthouse: 1,700,000 $ x 126.5/108 = 1,991,204

The hospital will cost $2.6 million.

2,635,417 minus 1,991,204, or $644,213, is the difference with the courthouse. The cost of the hospital is $644,21300 more than the Courthouse.

3√3 is the area of a parallelogram ABCD if three of its vertices are A (2, 4), B (2 + √(3),5) and C (2,6) . Option (C) is correct.

The given vertices of a parallelogram are A (2, 4), B (2 + √(3),5) and C (2,6).

To find the area of the parallelogram using the above points, we will have to use the formula of area of parallelogram.

Area of parallelogram = base × height

In parallelogram ABCD, AB is parallel to DC. If we join AC, then parallelogram ABCD will be divided into two triangles ABC and ACD. Similarly, If we join BD, parallelogram ABCD will be divided into two triangles ABD and BCD.

Then, Area of parallelogram ABCD = area of triangle ABC + area of triangle CD

Area of parallelogram ABCD = area of triangle ABD + area of triangle BCD

Either way, we will have the same area of parallelogram ABCD.

Therefore, we will use any of the triangles for calculation.

Let's consider triangle ABC. So, the area of the parallelogram = base × height

Let AD be the height of the triangle ABCAD = y-coordinate of vertex C - y-coordinate of vertex A= 6 - 4 = 2

Now, we need to calculate the length of AB.

Base = AB = √[ (x2 − x1)² + (y2 − y1)² ] = √[(2 + √(3) − 2)² + (5 − 4)²] = √[3 + 1] = √4 = 2

Therefore, Area of parallelogram ABCD = Base × height= 2 × 2= 4 sq. units. Hence, option (d) Can't be determined is incorrect. The correct answer is (c) 3√3, which is the closest answer.
