Answer:

(fog)(x) = 4x - 7

Step-by-step explanation:

f(x) = 2x-1 and g(x) = 2x-3;

(fog)(x) = f(g(x)

= f(2x - 3) = 2(2x - 3) - 1

= 4x - 6 - 1

= 4x - 7

Answer:

y = \(\frac{1}{3}\) x + \(\frac{10}{3}\)

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate the slope m of H using the slope formula

m = \(\frac{y_{2}-y_{1} }{x_{2}-x_{1} }\)

with (x₁, y₁ ) = (0, - 3) and (x₂, y₂ ) = (3, - 2) ← 2 points on the line

m = \(\frac{-2+3}{3-0}\) = \(\frac{1}{3}\)

Parallel lines have equal slopes, thus

y = \(\frac{1}{3}\) x + c ← is the partial equation

To find c substitute (- 4, 2) into the partial equation

2 = - \(\frac{4}{3}\) + c ⇒ c = 2 + \(\frac{4}{3}\) = \(\frac{10}{3}\)

y = \(\frac{1}{3}\) x + \(\frac{10}{3}\) ← equation of parallel line

According to the Central Limit Theorem, for a sufficiently large sample size, the distribution of sample means will be approximately normal, regardless of the shape of the population distribution.

To calculate the probability, we need to convert the sample mean score to a z-score and then find the corresponding area under the standard normal distribution curve.

Calculate the standard error of the mean (SE):

SE = σ / sqrt(n)

SE = 127 / sqrt(72)

SE ≈ 14.96

Calculate the z-score:

z = (X - μ) / SE

z = (567 - 572) / 14.96

z ≈ -0.334

Find the probability corresponding to the z-score:

We can find the area to the left of the z-score -0.334. Let's denote this probability as P(z < -0.334).

The probability that the sample mean score is less than 567 is approximately equal to P(z < -0.334).

The explicit formula for the given sequence is an = 2 + n².

To find the explicit formula for the given sequence, we need to identify the pattern or rule that generates the terms. By observing the sequence, we can see that each term is obtained by adding consecutive odd numbers to the previous term.

Let's break it down step by step:

The first term, a1, is given as 2.

To obtain the second term, a2, we add 3 (the first odd number) to a1: 2 + 3 = 5.

To obtain the third term, a3, we add 5 (the second odd number) to a2: 5 + 5 = 10.

To obtain the fourth term, a4, we add 7 (the third odd number) to a3: 10 + 7 = 17.

To obtain the fifth term, a5, we add 9 (the fourth odd number) to a4: 17 + 9 = 26.

From the observations above, we can see that each term can be obtained by adding the sum of the first n odd numbers (1, 3, 5, 7, ...) to the first term, a1.

The sum of the first n odd numbers is given by the formula: n^2.

Therefore, the explicit formula for the given sequence is:

an = a1 + n²

Substituting the given value of a1 = 2 into the formula, we have:

an = 2 + n²

So, the explicit formula for the given sequence is an = 2 + n².

47.12 liters

Option C is correct

86 inches are equivalent to 7.17 feet

To convert inches to feet, you can divide the number of inches by 12 (since there are 12 inches in a foot):

86 inches ÷ 12 inches/foot = 7.17 feet

The units of measurement used to measure length or distance are inches and feet. One inch is equivalent to one-twelfth of a foot, while one foot is equal to twelve inches. As a result, you may easily convert feet to inches by multiplying the number of feet by 12. 36 inches, for instance, is equivalent to 3 feet (3 feet x 12 inches/foot).

Divide the number of inches by 12 to convert the measurement to feet. As an illustration, 24 inches (12 inches per foot) equals 2 feet.

Inches and feet are often used to measure an object's height, breadth, and length in the United States.

When x = π/4 and dx = -0.3, dy = -2.4 and δy = 2.4. δx is an infinitesimal change in x

To find the differential of y, we differentiate y = 4tanx with respect to x. Using the derivative rules, we have dy = 4(sec^2x)dx.

To evaluate dy and δy when x = π/4 and dx = -0.3, we substitute these values into the expression for dy.

When x = π/4, sec^2(π/4) = 2, so dy = 4(2)dx = 8dx.

Given that dx = -0.3, we can calculate dy as follows: dy = 8(-0.3) = -2.4.

To evaluate δy, we use the fact that δx is an infinitesimal change in x. Therefore, δx = 0.3.

Using δy = dy = 4(sec^2x)δx, we substitute x = π/4 and δx = 0.3: δy = 4(2)(0.3) = 2.4.

Using the formula for an infinite geometric series, the sum of the given series can be estimated as S ≈ 6.00000.

To estimate the sum of the series n = 1 to infinity of (2n+1) - 9, we can use the formula for an infinite geometric series:

S = a / (1 - r)

where S is the sum of the series, a is the first term, and r is the common ratio. In this case, a = (2(1)+1) - 9 = -6 and r = 2.

Thus, we can estimate the sum as:

S ≈ -6 / (1 - 2) = 6

To express this answer correct to five decimal places, we would write:

The objective function is "min 2m + 3b" which represents the cost of making m units and buying b units. To find the optimal solution, we need to minimize this cost. To begin, we are given that the total number of units needed is 4000. This implies that m + b = 4000.

Now, let's solve for m and b separately.
1. Solving for m:
We want to minimize the cost of making m units, which costs $2 per unit. Therefore, the cost of making m units is 2m dollars.
2. Solving for b:
We want to minimize the cost of buying b units, which costs $3 per unit. Therefore, the cost of buying b units is 3b dollars.

To summarize:
- The cost of making m units is 2m dollars.
- The cost of buying b units is 3b dollars.
- The total number of units needed is 4000, so m + b = 4000.

The proportion of the variation in the dependent variable y that is explained by the estimated regression equation is measured by the coefficient of determination.

What is coefficient of determination?

The effectiveness of a statistical model in forecasting a result is shown by the coefficient of determination (R²). The dependent variable in the model is a representation of the result.

R² can have a value of 0 or 1, with 1 being the maximum achievable. Simply said, a model's R² will be closer to 1 the more accurate its predictions are.

R² is a more precise measure of goodness of fit. The amount of volatility in the dependent variable that the model can account for.

You can typically tell whether your linear regression data's R² is high or low by graphing it. The graphs below, for instance, display two sets of simulated data:

Consequently, the following are the first partial derivatives of g(x,y,z) = 6x2yz3 - 7x/y:

G/x equals (12xyz3) - (7/y).

G/Y equals (6x2z3) - (7x/y2)

∂g/∂z = (18x²y²z²)

To find the first partial derivatives of the function g(x,y,z) = 6x²yz³ - 7x/y, we need to take the partial derivative of the function with respect to each of its variables, one at a time.

Let's start with x:

The partial derivative of g with respect to x is found by treating y and z as constants and differentiating 6x²yz³ and 7x with respect to x.

So,

∂g/∂x = (12xyz³) - (7/y)

Next, let's take the partial derivative with respect to y:

The partial derivative of g with respect to y is found by treating x and z as constants and differentiating 6x²yz³ and 7x/y with respect to y.

So,

∂g/∂y = (6x²z³) - (7x/y²)

Finally, let's take the partial derivative with respect to z:

The partial derivative of g with respect to z is found by treating x and y as constants and differentiating 6x²yz³ with respect to z.

So,

∂g/∂z = (18x²y²z²)

The statement "The number of intervals tells you the size of the data set" is not true of histograms. Option A

The number of intervals, or bins, in a histogram is determined by the data and by the preferences of the person creating the graph. A larger number of intervals will result in a graph with more detail, but may also make it harder to see trends or patterns in the data.

The size of the data set is not determined by the number of intervals in a histogram, but by the number of data points that are being represented.

The price that the customer pays after the VAT is Rs. 21,470.

In the question, we are given that the selling price of an article is Rs. 19000, and 13% VAT is levied on it.

We are asked to find the price that the customer pay.

The total price that the customer pays is the sum of the selling price and the VAT that he/she needs to pay.

The selling price is given to be Rs. 19000.

The VAT is 13%, that is, 13% of Rs. 19000 = Rs. 0.13*19000 = Rs. 2470.

Thus, the total price that the customer pays = The selling price + The VAT,

7:5 mean that to every 7 men there is 5 woman.

There are 54 women working for the company.

The ratio is defined as a relationship between two quantities, it is expressed as one divided by the other.

The ratio of men to women working for the company is 7:5, which means that for every 7 men, there are 5 women.

We can express this as a fraction by writing 7/7 as 1 and 5/7 as 5/7, so the ratio becomes 1:5/7.

This fraction can be rewritten as 7/7:35/7, and since the two fractions have the same denominator, we can say that the ratio is equal to 7:35.

Since there are 192 total employees, and the ratio of men to women is 7:35, we can set up the following proportion:

7/35 = x/192

We can solve this proportion by cross-multiplying:

7/35 × 192 = x

This simplifies to:

x = 54
