Answer:  (x² - 5)(x - 7)

Step-by-step explanation:

Grouping the terms, we have:

(x^3 - 7x^2) + (-5x + 35)

Now, let's factor out the common factors from each pair:

x^2(x - 7) - 5(x - 7)

Notice that we have a common factor of (x - 7) in both terms. We can factor it out:

(x^2 - 5)(x - 7)

Therefore, the resulting expression after factoring by grouping is (x^2 - 5)(x - 7).

The two numbers are 20 and 32.

Let's assume the two numbers in the ratio 10:16 are 10x and 16x, where x is a common factor.

According to the given information, when 4 is added to each number, the ratio becomes 4:6. This means that the new numbers are (10x + 4) and (16x + 4).

To find the numbers, we can set up an equation based on the given ratios:

(10x + 4) / (16x + 4) = 4/6

To simplify the equation, we can cross-multiply:

6(10x + 4) = 4(16x + 4)

Expanding both sides:

60x + 24 = 64x + 16

Bringing like terms together:

60x - 64x = 16 - 24

-4x = -8

Dividing both sides by -4:

x = 2

Now that we have the value of x, we can substitute it back into the original ratios to find the numbers:

The first number = 10x = 10 * 2 = 20

The second number = 16x = 16 * 2 = 32

Therefore, the two numbers are 20 and 32.

Answer:

Let the two numbers be 10x and 16x.

When 4 is added to each, the resulting numbers are (10x + 4) and (16x + 4).

According to the problem, the ratio of (10x + 4) to (16x + 4) is 4:6.

We can write this as:

(10x + 4)/(16x + 4) = 4/6

Cross-multiplying, we get:

6(10x + 4) = 4(16x + 4)

Simplifying the equation, we get:

60x + 24 = 64x + 16

48 = 4x

x = 12

Therefore, the two numbers are:

10x = 120

16x = 192

So the two numbers are 120 and 192.

In approximately the year 2001 (or the 1.373rd year since 2000), the approximate number of oil barrels imported from Country B per day will be 1.93 million.

To solve the equation y = 0.069x + 1.24 for x, we need to isolate x on one side of the equation. Let's rearrange the equation:

y = 0.069x + 1.24

Subtract 1.24 from both sides:

y - 1.24 = 0.069x

Divide both sides by 0.069:

(y - 1.24) / 0.069 = x

Now we have x isolated on one side of the equation. We can use this equation to determine the year in which the approximate number of oil barrels imported from Country B per day will be 1.93 million.

Let's substitute y = 1.93 into the equation:

(x - 1.24) / 0.069 = 1.93

Multiply both sides by 0.069:

x - 1.24 = 0.069 * 1.93

x - 1.24 = 0.13317

Add 1.24 to both sides:

x = 0.13317 + 1.24

x = 1.37317

Now we have the value of x, which represents the number of years since 2000. To determine the year, we add the value of x to 2000:

Year = 2000 + 1.37317

Year ≈ 2001.373

The probability of obtaining exactly 2 frozen rains after defeating 20 Frigid Elements in the video game is approximately 0.2713 or 27.13%.

q = 1 - p

q = 1 - 0.019

q = 0.981

X: The number of successful outcomes.

In this scenario, we can model the situation using a binomial distribution. Let's determine the values of n, p, q, and X:

n: The number of trials or attempts.

In this case, the number of trials is the number of Frigid Elements defeated, which is given as 20.

n = 20

p: The probability of success on a single trial.

The probability of a frozen rain item dropping after defeating a Frigid Element is given as 1.9%, which can be expressed as 0.019.

p = 0.019

q: The probability of failure on a single trial.

The probability of failure is the complement of the probability of success. Therefore:

q = 1 - p

q = 1 - 0.019

q = 0.981

X: The number of successful outcomes.

We want to find the probability of 2 frozen rains dropping, so X is 2.

X = 2

Now that we have determined the values, we can calculate the probability using the binomial distribution formula. The formula for the probability mass function of the binomial distribution is:

P(X = x) = [tex](nCx) * (p^x) * (q^(n-x))[/tex]

where nCx represents the binomial coefficient, which is the number of ways to choose x successes out of n trials.

Using this formula, we can substitute the values into the equation:

P(X = 2) = [tex](20C2) * (0.019^2) * (0.981^(20-2))[/tex]

Calculating the binomial coefficient:

(20C2) = (20!)/(2!(20-2)!)

= (20 * 19 * 18!)/(2 * 18!)

= (20 * 19)/(2 * 1)

= 190

Now substituting the values:

P(X = 2) = [tex]190 * (0.019^2) * (0.981^18)[/tex]

Now we can calculate the probability:

P(X = 2) ≈ 0.2713 or 27.13% (rounded to two decimal places)

Therefore, the probability of obtaining exactly 2 frozen rains after defeating 20 Frigid Elements in the video game is approximately 0.2713 or 27.13%.

In sampling distributions, the mean is consistently identical to the population mean. (Option C)

This concept is a fundamental property of sampling distributions and is rooted in the principles of probability and statistical theory. A sampling distribution is a theoretical distribution that represents the possible values of a statistic (such as the mean or proportion) calculated from different samples drawn from the same population. The mean of a sampling distribution is an average of the sample means, and it provides an estimate of the population mean.

When random samples are drawn from a population, the mean of each sample will vary due to random sampling variability. However, as the sample size increases, the distribution of sample means tends to converge around the population mean. This phenomenon is known as the Central Limit Theorem.

According to the Central Limit Theorem, as sample sizes become large (typically n > 30), the sampling distribution of the mean becomes approximately normal, with a mean that is identical to the population mean. In other words, on average, the sample means will be equal to the population mean. This property holds true regardless of the shape, spread, or other characteristics of the population distribution.

Therefore, the correct answer is C. Identical to.

Multiplying two signed numbers results in a product, and the sign of the product depends on the signs of the multiplied numbers.

Multiplying and dividing two signed numbers differ in terms of the rules and properties that apply to each operation. Here are the key differences:

1. Product vs. Quotient:

When multiplying two signed numbers, the result is called the product. It represents the total of repeated addition or combining equal groups. For example, multiplying -3 by -4 gives a product of 12.

When dividing two signed numbers, the result is called the quotient. It represents the ratio or partitioning of one quantity into equal parts. For example, dividing 12 by -4 gives a quotient of -3.

2. Signs of the Result:

In multiplication, the sign of the product depends on the signs of the multiplied numbers. If the signs are the same (both positive or both negative), the product is positive. If the signs are different (one positive and one negative), the product is negative. For example, (-3) * (-4) = 12, and (-3) * 4 = -12.

In division, the sign of the quotient depends on the signs of the dividend and divisor. If both numbers have the same sign, the quotient is positive. If the numbers have different signs, the quotient is negative. For example, 12 / (-4) = -3, and (-12) / (-4) = 3.

3. Properties:

Multiplication has properties like the commutative property (changing the order of the factors doesn't change the product) and the associative property (changing the grouping of factors doesn't change the product). For example, (-3) * (-4) = (-4) * (-3) = 12.

Division, on the other hand, has specific properties like the division property of zero (dividing any number by zero is undefined) and the division property of one (dividing a number by one leaves the number unchanged). For example, 12 / 1 = 12.

In summary, multiplying two signed numbers results in a product, and the sign of the product depends on the signs of the multiplied numbers. Dividing two signed numbers results in a quotient, and the sign of the quotient depends on the signs of the dividend and divisor. Additionally, multiplication has properties like commutativity and associativity, while division has properties specific to the division operation.

Rental cost for each movie = $3.25

Rental cost for each video game = $5.25

Step-by-step explanation:

We can find the rental cost for each movie and each video game using a system of equations where:

First equation:

Since Jina rented 6 movies and 2 video games for a total of $30, our first equation is given by:

6M + 2V = 30

Second equation:

Since Jina also rented 3 movies and 5 video games for a total of $36, our second equation is given by:

3M + 5V = 36

Method to solve:  Elimination:

We can solve this with eliminate.  First, we need to multiply the second equation by -2.  Then, we must add the two equations to eliminate the Ms and solve for V:

Multiplying the entire second equation by -2:

-2(3M + 5V = 36)

-6M - 10V = -72

Adding the two equations:

    6M + 2V = 30

+

   -6M - 10V = -72

(6M - 6M) + (2V - 10V) = (30 - 72)

-8V = -42

Solving for V:

(-8V = -42) / -8

V = 5.25

Thus, the rental cost for each video game is $5.25.

Solving for M:

We can now find M by plugging in 5.25 for V in any of the two equations in our system.  

Let's use the first equation:

Plugging in 5.25 for V in 6M + 2V = 30 to solve for M:

6M + 2(5.25) = 30

(6M + 10.50 = 30) - 10.50

(6M = 19.50) / 6

M = 3.25

Thus, the rental cost for each movie is $3.25.

c). Probability of drawing 3 balls of the same color = 259/1771 = 0.146

(a) Probability of drawing 3 white balls:

Total number of balls = 7 red + 12 white + 4 green = 23 balls

Number of favorable outcomes = selecting 3 white balls = 12C3 = (12!)/(3!(12-3)!) = 220

Total number of possible outcomes = selecting 3 balls from 23 = 23C3 = (23!)/(3!(23-3)!) = 1771

So, Probability of drawing 3 white balls = Number of favorable outcomes / Total number of possible outcomes

P(3 white balls) = 220/1771 = 0.124

b). Probability of drawing one ball of each color:

Number of favorable outcomes = selecting 1 ball of each color = 7C1 × 12C1 × 4C1 = 7 × 12 × 4 = 336

Answer: D

Step-by-step explanation: X is being subtracted by 1 so it will now add 1 in the inverse

The derivative of f(x) = 6x + 1 at x = 2 is 6, obtained through the limit definition of the derivative.

To find the derivative of f(x) = 6x + 1 at x = 2, we can use the formula for the derivative of a function: f'(x) = lim(h → 0) [f(x + h) - f(x)]/h

We substitute x = 2 into the formula to get: f'(2) = lim(h → 0) [f(2 + h) - f(2)]/h

We plug in f(x) = 6x + 1: f'(2) = lim(h → 0) [(6(2 + h) + 1) - (6(2) + 1)]/h

Simplifying the expression:

f'(2) = lim(h → 0) [(12 + 6h + 1) - (12 + 1)]/h

      = lim(h → 0) (6h)/h = lim(h → 0) 6

The limit of 6 as h approaches 0 is simply 6. Therefore, the derivative of f(x) = 6x + 1 at x = 2 is f'(2) = 6.

The derivative of f(x) = 6x + 1 at x = 2 is 6.

Step-by-step explanation:

the transaction results in a net gain.Net gain percentage = Net gain / Total cost price × 100%=(2SP - 52000) / 52000 × 100%Now, we can use the above expressions to calculate the total gain or loss percentage in the transaction.

Let's assume that the cost price of the first television set is CP1 and that of the second is CP2. As per the given information, the total cost price of both television sets is 52000 rupees.

Therefore, CP1 + CP2 = 52000Assuming the selling price of both television sets is the same, let's assume it to be SP for convenience. Selling price is defined as the price at which a product is sold to the customer. Therefore, the selling price of both television sets will be SP.

Now, we have to calculate the net gain or loss percentage in the transaction.Gain or loss is calculated as the difference between the selling price and cost price.

Gain or loss on the first television set is 10% of CP1, and the gain or loss on the second television set is 10% of CP2. Therefore,Gain or loss on the first television = 10/100 × CP1 = 0.1CP1Loss or gain on the second television = 10/100 × CP2 = 0.1CP2The selling price of both television sets is the same.

Therefore,Selling price of the first television = SPSelling price of the second television = SPThe selling price of both television sets combined is:Selling price of both television sets = SP + SP = 2SPNow, let's calculate the net gain or loss percentage in the transaction.

Net gain or loss = Selling price - Cost price= (SP + SP) - (CP1 + CP2)= 2SP - 52000Now, we need to determine whether the transaction resulted in a gain or a loss. We know that the gain or loss on the first television is 0.1CP1, and the gain or loss on the second television is 0.1CP2.

cases:Case 1: When CP1 < CP2 (the cost price of the first television is less than that of the second television)In this case, the gain on the first television is less than the loss on the second television, as 0.1CP1 < 0.1CP2. Therefore, the transaction results in a net loss.

Net loss percentage = Net loss / Total cost price × 100%=(2SP - 52000) / 52000 × 100%

Case 2: When CP1 > CP2 (the cost price of the first television is greater than that of the second television)In this case, the gain on the first television is greater than the loss on the second television, as 0.1CP1 > 0.1CP2.
