What is long division method and its steps ?

When splitting huge numbers, the task is divided into several sequential parts using the long division approach. The dividend is divided by the divisor, just as in conventional division problems, and the result is known as the quotient; occasionally, it also produces a remainder.

We need to comprehend a few stages in order to divide. A vinculum or right parenthesis separates the dividend from the quotient, while a vertical bar separates the divisor from the dividend. Let's now go through the long division stages listed below to comprehend the procedure.

1. Take the dividend's first digit starting from the left . Verify if this digit exceeds or is equal to the divisor.

2. Next, divide it by the divisor, and write the result as the quotient on top.

3. Subtract the outcome from the digit, and then put the difference below.

Step 4: Decrease the dividend's subsequent digit (if present).

Step 5: Carry out Step 4 again.

The 12th mortgage payment is 23,998.11 pesos, which is calculated based on the loan amount, 2 years of accrued interest, and the monthly mortgage payment formula.

To calculate the amount of the 12th mortgage payment, we need to break down the steps involved:

1. Calculate the loan amount after 2 years of accruing interest:

The loan amount after 2 years will be the sum of the initial loan amount and the accrued interest. Since the interest is compounded semi-annually at a rate of 15%, the formula for calculating the future value (FV) of the loan after 2 years is:

FV = PV * (1 + r/2)²ⁿ

Where PV is the present value (loan amount), r is the interest rate, and n is the number of compounding periods.

In this case:

PV = 2,000,000 pesos

r = 15% = 0.15

n = 2 years

FV = 2,000,000 * (1 + 0.15/2)²²

FV = 2,000,000 * (1 + 0.075)⁴

FV ≈ 2,479,095.31 pesos

2. Calculate the monthly mortgage payment for the first 5 years:

The monthly mortgage payment during the first 5 years is half of the payments from the 6th to the 30th year. Since the mortgage is for 30 years, there are 360 monthly payments.

The formula for calculating the monthly mortgage payment is:

PMT = PV * (r/12) / (1 - (1 + r/12)⁽⁻ⁿ⁾)

Where PMT is the monthly payment, PV is the loan amount, r is the monthly interest rate, and n is the number of months.

In this case:

PV = 2,479,095.31 pesos (calculated in step 1)

r = 12% = 0.12

n = 360 months (30 years)

PMT = 2,479,095.31 * (0.12/12) / (1 - (1 + 0.12/12)⁽⁻³⁶⁰⁾)

PMT ≈ 23,998.11 pesos

3. Calculate the amount of the 12th mortgage payment:

Since the first monthly mortgage payment is made exactly 2 years after the loan is requested, the 12th mortgage payment corresponds to the payment made in the 13th month.

Therefore, the amount of the 12th mortgage payment is approximately 23,998.11 pesos.

In conclusion, the amount of the 12th mortgage payment is approximately 23,998.11 pesos. This calculation takes into account the initial loan amount, accrued interest over 2 years, and the monthly mortgage payment formula.

The chi-square goodness-of-fit test can provide important information about whether the observed data significantly deviates from the expected distribution, which categories or bins contribute to the deviation, and the overall goodness-of-fit of the data to the expected distribution.

The chi-square goodness-of-fit test is a statistical test used to determine if a sample of data comes from a population with a specific distribution. Specifically, the test compares the observed frequencies of data in different categories or bins with the expected frequencies of data in those categories based on a hypothesized distribution.

It can determine whether the observed data significantly deviates from the expected distribution. If the test results in a p-value less than the chosen level of significance, it indicates that the observed data significantly deviates from the expected distribution, and the null hypothesis (that the data follows the expected distribution) can be rejected.

It can identify which categories or bins contribute the most to any significant deviation. The test statistic and associated p-value can help to identify which categories or bins show significant differences between the observed and expected frequencies.

It can provide information on the overall goodness-of-fit of the data to the expected distribution. The test statistic provides a measure of the overall goodness-of-fit, with higher values indicating greater deviation from the expected distribution.

Answer:

The slope of the line is 3.

Step-by-step explanation:

Given function;

x(t) = -t² + 5t

y(t) = 3t, when t = 2

\(\frac{dx}{dt} = -2t + 5\)

\(\frac{dy}{dt} = 3\)

\(\frac{dy}{dx}= \frac{dy}{dt} \ \times \ \frac{1}{\frac{dx}{dt} } \\\\\frac{dy}{dx}= 3 \ \times \frac{1}{-2t + 5} \\\\\frac{dy}{dx}= \frac{3}{-2t + 5}\)

t = 2

\(Then, \ \frac{dy}{dx}= \frac{3}{-2(2) + 5} \\\\\frac{dy}{dx}= \frac{3}{-4 + 5} \\\\\frac{dy}{dx}= \frac{3}{1} \\\\\frac{dy}{dx}= 3\)

Therefore, the slope of the line is 3.

Answer:

The joint pmf of X and Y is:

Px,y(0,1) = 1/4

Px,y(1,0) = 1/4

Px,y(1,1) = 1/4

Px,y(2,0) = 1/4

To find the joint probability mass function (pmf) of X and Y, we need to consider all possible outcomes of the two independent flips of a fair coin.

There are four possible outcomes:

H, H (heads on the first flip and heads on the second flip)

H, T (heads on the first flip and tails on the second flip)

T, H (tails on the first flip and heads on the second flip)

T, T (tails on the first flip and tails on the second flip)

Let's calculate the probability of each outcome first:

P(H, H) = 1/4

P(H, T) = 1/4

P(T, H) = 1/4

P(T, T) = 1/4

Now we define X as the total number of tails and Y as the number of heads on the last flip. We can calculate the values of X and Y for each outcome:

X = 0 (no tails), Y = 1 (one head on the last flip)

X = 1 (one tail), Y = 0 (no heads on the last flip)

X = 1 (one tail), Y = 1 (one head on the last flip)

X = 2 (two tails), Y = 0 (no heads on the last flip)

We can now calculate the probability of each combination of X and Y:

P(X=0, Y=1) = P(H, H) = 1/4

P(X=1, Y=0) = P(H, T) = 1/4

P(X=1, Y=1) = P(T, H) = 1/4

P(X=2, Y=0) = P(T, T) = 1/4

since the coin is fair, the probability of getting a head or a tail on each flip is 1/2.

Let's consider all the possible outcomes of two independent flips .

The possible outcomes for X and Y are as follows:

If both flips are tails (outcome T,T), then X = 2 and Y = 0.

If the first flip is tails and the second flip is heads (outcome T,H), then X = 1 and Y = 1.

If the first flip is heads and the second flip is tails (outcome H,T), then X = 1 and Y = 0.

If both flips are heads (outcome H,H), then X = 0 and Y = 1.

For each outcome, we can calculate the joint probability as the product of the individual probabilities of each flip. For example, for the outcome T,H, the probability is P(T,H) = P(T) * P(H) = 1/4 * 1/2 = 1/8.

Using this approach, we can calculate the joint PMF for each possible value of X and Y as follows:

P(X=2, Y=0) = P(T,T) = 1/4

P(X=1, Y=1) = P(T,H) = 1/8

P(X=1, Y=0) = P(H,T) = 1/8

P(X=0, Y=1) = P(H,H) = 1/4

Therefore, the joint PMF of X and Y is given by:

Y=0 Y=1

X=0 0 1/4

X=1 1/8 0

X=2 1/4 0

This table shows the probability of each possible pair of values for X and Y. For example, P(X=1, Y=0) = 1/8, indicating that there is a 1/8 probability of getting one tail and then a head on the second flip.

The ladder can reach 78.40 feet.

According to the Pythagoras theorem, the square of the hypotenuse of a triangle, which has a straight angle of 90 degrees, equals the sum of the squares of the other two sides.

The formula for the Pythagoras theorem is written as c² = a² + b², where c is the hypotenuse of the right triangle and a and b are its other two legs. As a result, the Pythagoras equation can be used to any triangle that has one angle that is exactly 90 degrees to create a Pythagoras triangle.

Given:

Hypotenuse = 82 feet

Base = 24 feet

Using Pythagoras theorem

H²= P² + B²

82² = P²+ 24²

6724 = P²+ 576

P² = 6148

P= 78. 40 feet

Side-Angle-Side, as it suggests, is when a triangle is congruent by the order of congruent side, congruent angle, and another congruent side. If named certain ways, they can be congruent. Since the question does not provide a specific way of naming the triangles, we can assume that any way is allowed. 2.5 and 2.5 are congruent, followed by angles D and G which have the congruent angle markers. The congruent angles are followed by 1.7 and 1.7, making the triangles congruent by Side-Angle-Side.

Sample variance and standard deviation are considered biased estimates of population variance and standard deviation because they tend to underestimate the true population variance and standard deviation.

The reason for this is that the sample variance and standard deviation are based on a sample of the population, not the entire population. The sample may not accurately represent the entire population, and thus the sample variance and standard deviation may not accurately reflect the true population variance and standard deviation. To correct for this bias, a correction factor is usually added to the sample variance calculation. For example, when estimating the population variance from a sample of size n, the sample variance is divided by (n-1) instead of n. This correction factor helps to provide a more accurate estimate of the population variance. Similarly, the sample standard deviation is calculated as the square root of the sample variance, and the correction factor is also applied to the sample standard deviation calculation. This corrected sample standard deviation is known as the unbiased sample standard deviation.
