The coordinates of triangle RST after it is translated four units right and three units up are (0, 5), (7, 8) and (0, -1)

From the figure, the coordinates of the triangle RST are:

R = (-4, 2)

S = (3, 5)

T = (-4, -4)

The rule of translation is given as:

This is represented as:

(x, y) = (x + 4, y + 3)

So, we have:

R' = (-4 + 4, 2 + 3) = (0, 5)

S' = (3 + 4, 5 + 3) = (7, 8)

T = (-4 + 4, -4 + 3) = (0, -1)

Hence, the coordinates of triangle RST after it is translated four units right and three units up are (0, 5), (7, 8) and (0, -1)

The amount of commission the agent receives if the bonus amount is Rs. 1,500, is Rs. 24,000.

To find the commission received by the agent, we first determine the excess sales using the bonus rate and bonus amount.

The excess sales are added to Rs. 900,000 to determine the total sales for the year.

The commission rate is applied to the total sales to ascertain the amount of the commission the agent received.

Commission on the total annual sales = 2%

Bonus on the excess of sales over Rs. 900,000 = 0.5%

Bonus amount = Rs. 1,500

Excess sales over Rs. 900,000 = Rs. 300,000 (Rs. 1,500/0.5%)

Total sales = Rs. 1,200,000 (Rs. 900,000 + Rs. 300,000)

Commission amount = Rs. 24,000 (Rs 1,200,000 x 2%)

Answer:

(x²-10x+33)/(-8) = y

Step-by-step explanation:

The distance between any point on a parabola from both its focus and directrix are the same.

Let's say we have a point (x,y) on the parabola. We can then say that using the distance formula,

\(\sqrt{(x-5)^2+(y-(-3))^2}\)is the distance between (x,y) and the focus. Similarly, the distance between (x,y) and the directrix is |y-1| (I use absolute value here because distance is always positive). We can find this equation by taking the shortest distance from the point to the line. Because the closest point to the line will be the same x value as the point itself, the distance is simply the distance between the y value of the point and the y value of the directrix.

Equating the two equations given, we have

\(\sqrt{(x-5)^2+(y-(-3))^2} = |y-1|\)

square both sides to get

(x-5)²+(y+3)²=(y-1)²

expand the y components

(x-5)² + y²+6y+9 = y²-2y+1

subtract y²+6y+9 from both sides

(x-5)² = -8y - 8

expand the x components

x²-10x+25 = -8y - 8

add 8 to both sides to isolate the -8y

x²-10x+33 = -8y

divide both sides by -8 to isolate y

(x²-10x+33)/(-8) = y

3cm is the length of the third side.

Given that an obtuse triangle with area 12 has two sides of lengths 4 and 10.

To find the length of the third side, we can use the formula for the area of a triangle; Area of a triangle = 1/2 × base × height, where base and height are perpendicular to each other.

Considering 4 and 10 as the base and height of the triangle respectively, the area of the triangle will be;

Area of the triangle = 1/2 × 4 × 10Area of the triangle

= 20 cm²

But given that the area of the triangle is 12 cm².

Thus, 20 cm² = 1/2 × 4 × 10 ⇒ length of the third side = 3 cm

So the answer is E[X] = 1.2, which is approximately equal to 1.

What is probability?

Probability is a measure of the likelihood of an event occurring. It is a number between 0 and 1, where 0 means the event is impossible and 1 means the event is certain to happen.

Let's first consider the probability of a boy being in the front half of the line. There are two possible cases:

The first half of the line contains exactly one boy: There are three boys and seven girls, so the probability of this happening is (3/10)*(7/9) = 7/30. The probability of any one of the three boys being in the front half of the line is therefore 7/30 * 3 = 7/10.

The first half of the line contains exactly two or three boys: There are three boys and seven girls, so the probability of this happening is (3/10)(2/9) + (3/10)(3/9) = 3/10. The probability of any one of the three boys being in the front half of the line is therefore 3/10 * 1 = 3/10.

So, the probability distribution for X is:

X = 0 with probability (7/10)(6/9) = 14/30

X = 1 with probability (7/10)(3/9) + (3/10)(7/9) = 21/30

X = 2 with probability (3/10)(2/9) + (3/10)*(3/9) = 9/30

Now we can calculate the expected value of X:

E[X] = 0*(14/30) + 1*(21/30) + 2*(9/30) = 1.2

So the answer is E[X] = 1.2, which is approximately equal to 1.

To reduce bias when conducting an experiment, it is important to employ methods that minimize the influence of confounding factors and ensure the results are representative of the population.

Randomization plays a key role in reducing bias by eliminating systematic patterns in treatment assignment. By randomly assigning treatments, all types of members in the population have an equal chance of receiving each treatment, which helps mitigate bias. Additionally, choosing a random sample from the population enhances the generalizability of the results and reduces bias that could arise from selecting a non-representative sample.

The researcher choosing who gets which treatment can introduce bias because it allows for potential bias in treatment allocation based on preconceived notions or preferences.

Random assignment of treatments helps reduce bias by ensuring that the treatments are assigned without any systematic pattern. This allows for equal representation of all types of individuals in the population, minimizing potential confounding variables.

Assigning treatments in a way that ensures all results in the experiment are the same can lead to bias as it disregards individual differences and does not account for potential variations and interactions between treatments and participants.

Choosing a random sample from the population is important to reduce bias as it ensures that every individual in the population has an equal chance of being selected, increasing the likelihood of a representative sample. A random sample helps minimize selection bias, where certain groups are over- or under-represented, thus improving the generalizability of the findings to the larger population.

The scientist claims that 60% of U.S. adults believe humans contribute to an increase in global temperature. A 95% confidence interval for the proportion of U.S. adults who hold this belief is found to be (0.626, 0.674). This confidence interval supports the scientist's claim.

To determine if this confidence interval supports the scientist's claim, we need to examine whether the claimed proportion of 60% falls within the confidence interval.

The confidence interval (0.626, 0.674) indicates that we are 95% confident that the true proportion of U.S. adults who believe humans contribute to an increase in global temperature lies between 0.626 and 0.674. Since the claimed proportion of 60% falls within this range, it is within the confidence interval.

Therefore, we can conclude that the confidence interval supports the scientist's claim. This means there is strong evidence to suggest that a significant majority of U.S. adults believe humans contribute to an increase in global temperature, as the lower bound of the confidence interval is 62.6% and the upper bound is 67.4%.

If you have a jar with 15 marbles, containing 3 each of 5 different colors. you draw out all 15 marbles, one at a time then, there are 168,168 different sequences of colors possible.

To determine the number of different sequences of colors possible when drawing out all 15 marbles from a jar containing 3 each of 5 different colors, you can use the multinomial coefficient formula.

The formula is:
Number of sequences = (n!)/(n1! * n2! * ... * nk!)
where n is the total number of marbles, and n1, n2, ..., nk are the numbers of marbles of each color.

In this case, n = 15 (total marbles), and there are 3 marbles of each of the 5 colors (n1 = n2 = n3 = n4 = n5 = 3).

Plugging these values into the formula:
Number of sequences = (15!)/(3! * 3! * 3! * 3! * 3!)

Compute the factorials:
Number of sequences = (1,307,674,368,000)/(6 * 6 * 6 * 6 * 6)
Number of sequences = 1,307,674,368,000 / 7,776
Number of sequences = 168,168

So, there are 168,168 different sequences of colors possible when drawing out all 15 marbles from the jar.

The value of h'(2) is 25

The chain rule is a fundamental rule in calculus that provides a method to differentiate composite functions.

A composite function is a function that is formed by taking the output of one function and using it as the input of another function.

For instance, if we have two functions f(x) and g(x), then the composite function h(x) can be defined as h(x) = f(g(x)), where g(x) is the input to f(x).

here we have

h(x) = √6 + 5f(x)

Derivative of h(x) with respect to x

h'(x) = d/dx (√6 + 5f(x))

h'(x) = d/dx (√6) + d/dx (5f(x))

h'(x) = 0 + 5f'(x)

h'(x) = 5f'(x)

Now substitute x = 2 and f'(2) = 5, to find h'(2)

h'(2) = 5f'(2)

h'(2) = 5(5)

h'(2) = 25

The power series constructed is y(x) = a₀ + (-a₁/3)x + (-a₀/2)x² + (-a₁/3)x³ + (a₀/8)x⁴ + (a₁/15)x⁵ + ...

The Emden Equation and determine the coefficients a₀, a₁, a₂, a₃, a₄, and a₅, substitute a power series into the equation and match the coefficients term by term.

Let's assume the power series solution for y(x) is:

y(x) = a₀ + a₁x + a₂x² + a₃x³ + a₄x⁴ + a₅x⁵ + ...

Substituting this series into the Emden Equation, we have:

x(y'' + 2y' + xy) = 0.

Differentiating y(x) with respect to x, we get:

y' = a₁ + 2a₂x + 3a₃x² + 4a₄x³ + 5a₅x⁴ + ...

Differentiating again, we have:

y'' = = 2a₂ + 6a₃x + 12a₄x² + 20a₅x³ + ...

Now, let's substitute these expressions into the Emden Equation:

x((2a₂ + 6a₃x + 12a₄x² + 20a₅x³ + ...) + 2(a₁ + 2a₂x + 3a₃x² + 4a₄x³ + 5a₅x⁴ + ...) + x(a₀ + a₁x + a₂x² + a₃x³ + a₄x⁴ + a₅x⁵ + ...) )= 0.

Expanding and grouping terms by powers of x, we have:

(2a₂ + a₀) x + (6a₃ + 2a₁) x² + (12a₄ + 3a₂) x³ + (20a₅ + 4a₃) x⁴ + ... = 0.

For this equation to hold for all values of x, each coefficient of xⁿ must be equal to zero.

Therefore, we can determine the coefficients as follows:

Coefficient of x°: 2a₂ + a₀ = 0 => a₀ = -a₀/2.

Coefficient of x¹: 6a₃ + 2a₁ = 0 => a₃ = -a₁/3.

Coefficient of x²: 12a₄ + 3a₂ = 0 => a₄ = -a₂/4 = a₀/(2ₓ4) = a₀/8.

Coefficient of x³: 20a₅ + 4a₃ = 0 => a₅ = -a₃/5 = a₁/(3ₓ5) = a₁/15.

Therefore, the coefficients of the power series solution are:

a₀ = a₀ a₁ = -a₁/3 a₂ = -a₀/2 a₃ = -a₁/3 a₄ = a₀/8 a₅ = a₁/15

y(x) = a₀ + (-a₁/3)x + (-a₀/2)x² + (-a₁/3)x³ + (a₀/8)x⁴ + (a₁/15)x⁵ + ...
