Which multiplication expression is equivalent to this?

Answer:

\(\frac{1891}{125}\)

Step-by-step explanation:

You can take any number, such as 15.128, and write a 1 as the denominator to make it a fraction and keep the same value,

15.128 / 1

we count the numbers after the decimal in 15.128, and multiply the numerator and denominator by 10 if it is 1 number, 100 if it is 2 numbers, 1000 if it is 3 numbers,

Therefore, we multiply the numerator and denominator by 1000 to get the following fraction:

15128 / 1000

Then, we need to divide the numerator and denominator by the greatest common divisor (GCD) to simplify the fraction.

The GCD of 15128 and 1000 is 8. When we divide the numerator and denominator by 8, we get the following:

\(\frac{1891}{125}\)

Changing the value of SS2 to 100 would increase SSwithin and decrease the size of the F-ratio. Therefore, the correct answer is (d) increase SSwithin and decrease the size of the F-ratio.

If an analysis of variance (ANOVA) is used for the given data, and the value of SS2 is changed to 100, the effect would be to increase SSwithin and decrease the size of the F-ratio.
To explain this, let's first understand the terms involved:
- M1 and M2: Means of the two samples
- SS1 and SS2: Sum of Squares within each sample
- SSwithin: Total Sum of Squares within both samples
- F-ratio: The ratio used in ANOVA to compare variances between and within samples
Initially, we have the following values:
M1 = 15, M2 = 25, SS1 = 90, SS2 = 70
Now, let's change the value of SS2 to 100 and examine the effects.
Calculate the initial SSwithin:
SSwithin = SS1 + SS2
SSwithin = 90 + 70
SSwithin = 160
Calculate the new SSwithin after changing the value of SS2:
New SSwithin = SS1 + New SS2
New SSwithin = 90 + 100
New SSwithin = 190
The new SSwithin has increased after changing the value of SS2 to 100.
The F-ratio is calculated using the following formula:
F-ratio = MSbetween / MSwithin
Where MSbetween represents the variance between the samples and MSwithin represents the variance within the samples. Since SSwithin has increased, MSwithin will also increase, which results in a decrease in the F-ratio.
In conclusion, changing the value of SS2 to 100 would increase SSwithin and decrease the size of the F-ratio. Therefore, the correct answer is (d) increase SSwithin and decrease the size of the F-ratio.

When three standard six-faced dice are rolled, the probability that the sum of the three numbers rolled is 9 is equal to 10/216 or 5/108.

Total number of ways three dice can be rolled = 6 × 6 × 6 = 216.

Each dice can have any number from 1 to 6. The probability of rolling a particular number on a dice = 1/6.

The probability of rolling a particular number on three dice = (1/6) × (1/6) × (1/6) = 1/216.

In order to get a sum of 9, there are four combinations that can be rolled:

3 + 3 + 3 = 9

3 + 4 + 2 = 9

3 + 5 + 1 = 9

4 + 3 + 2 = 9

The probability of rolling any of these combinations = probability of rolling 3-3-3 + probability of rolling 3-4-2 + probability of rolling 3-5-1 + probability of rolling 4-3-2

= (1/216) + (3/216) + (3/216) + (3/216)

The correct option regarding how many times stronger the wave amplitude A of the earthquake was than the standard wave Ao is given by:

A = 39,811 Ao.

To find the ratio of A and Ao, which states how many times a earthquake measuring R in the Richter scale was stronger than the standard intensity Ao, we have to solve the following logarithmic function:

R = log(A/Ao)

The Richter scale of the earthquake in this problem is given as follows:

R = 4.6.

Hence the ratio of the measures is obtained as follows:

4.6 = log(A/Ao)

The power of 10 is the inverse function of the logarithm, hence if it is applied to both sides of the equation, then we can isolate the ratio A/Ao as follows:

A/Ao = 10^4.6

A/Ao = 39,811.

Applying cross multiplication, the ratio is given as follows:

A = 39,811 Ao.

What is proportionality?

Proportionality is a mathematical relationship between two variables, where one variable is a constant multiple of the other. In other words, two quantities are proportional if they maintain a constant ratio to each other, meaning that as one quantity increases or decreases, the other quantity changes in the same proportion.

We are given that the time it takes to print a batch of newspapers, m, is inversely proportional to the number of printers used, n, and the equation of proportionality is:

m = k/n

where k is a constant of proportionality. We are also given that when k = 100, the equation is satisfied. So we can substitute k = 100 into the equation to get:

m = 100/n

To find the time it will take to print a batch of newspapers if 20 printers are used, we can substitute n = 20 into the equation:

m = 100/20 = 5

So it will take 5 minutes to print a batch of newspapers if 20 printers are used. Rounded to 1 decimal place, the answer is 5.0 minutes.

The work of  5/6 more than 360 is equal to 660.

To calculate what 5/6 is out of 360, you can use the following steps:

Divide 360 by 6 (the denominator of the fraction) to determine the value of 1/6.

360 / 6 = 60 Multiply the value of 1/6 by the numerator (5) to find the value of 5/6.

60 * 5 = 300

Step 1: Calculate 5/6 of 360.

To find 5/6 of a number, you multiply that number by the fraction 5/6. In this case, we want to find 5/6 of 360. To do that, we multiply 360 by 5/6:

(5/6) * 360 = (5 * 360) / 6 = 1800 / 6 = 300

So, 5/6 of 360 is equal to 300.

Step 2: Add the result to 360.

To find 5/6 more than 360, we take the result from Step 1, which is 300, and add it to 360:

300 + 360 = 660

Therefore, 5/6 more than 360 is equal to 660.

In summary, by calculating 5/6 of 360, we found that it is 300. Adding 300 to 360 gives us the final result of 660, which represents 5/6 more than 360.

Step-by-step explanation:

Using the Central Limit Theorem, we can approximate the probability of the sum of 20 independent and identically distributed random variables, each with a probability density function (pdf) of f(x) = 2x, being less than or equal to 10.

The Central Limit Theorem states that when independent random variables are added, their sum tends towards a normal distribution regardless of the shape of the individual distributions, provided the sample size is sufficiently large. In this case, we have 20 independent random variables.

To apply the Central Limit Theorem, we need to calculate the mean and variance of the distribution. The mean of each X variable is given by E(X) = ∫x * f(x) dx, which in this case is ∫2x^2 dx = 2/3. The variance is given by Var(X) = ∫x^2 * f(x) dx - (E(X))^2, which becomes 1/18.

Using the properties of means and variances, the mean of the sum S is 20 * (2/3) = 40/3, and the variance of the sum is 20 * (1/18) = 20/18 = 10/9.

Now, we can standardize the sum using the mean and variance to approximate the probability. Z = (S - E(S))/√Var(S), where E(S) = 40/3 and Var(S) = 10/9. We want to find P(S ≤ 10), which is equivalent to P(Z ≤ (10 - E(S))/√Var(S)). Substituting the values, we find P(Z ≤ (10 - 40/3)/(√(10/9))). We can then use standard normal distribution tables or calculators to find the probability.

Statement in step 8 is the proof that <ABD and <EBC are complementary angles.

An angle in mathematics refers to an arc that joins two points. For angles to be formed there should be two points, the starting point and the ending point. In some cases the starting point coincides with the ending point, in this case the angle formed is 360 degrees which is equivalent to a circle. We can hence say that angle in a circle is 360 degrees

When angles are formed by two points in the same straight line or say two colinear points the angle formed here is 180 degree. Hence we say angles in a straight line is 180 degrees.  In a case where a line intersects the straight line, the intersecting line bisects the the angle in a straight line. The sum of the two angles formed is 180 degrees. Such angles are said to be supplementary angles.

Assuming the bisector of the straight line in a perpendicular bisector, here the angle 180 is divided into two equal parts then each angle is 90 degrees.

When angle 90 degrees is bisected two different angles are formed. The sum of these two angles are known as complementary angles.

Hence angle <ABD and <EBC are complementary angles formed from bisecting angle <DBC which is 90 degrees or a right angle triangle

The answer is d. the mean difference of a relationship is not measured and described by a correlation.

Correlation is a statistical technique used to measure the degree of association between two variables. It is used to describe the direction, form, and strength of the relationship between the variables. The direction of a relationship can be positive or negative, depending on whether the variables move in the same or opposite direction. The form of a relationship can be linear or nonlinear, depending on whether the relationship is a straight line or a curve. The strength of a relationship can be weak or strong, depending on how closely the variables are related to each other. However, correlation does not measure the mean difference of a relationship, which is a measure of central tendency that describes the average difference between two groups or variables.

In summary, correlation measures the direction, form, and strength of a relationship between two variables. It does not measure the mean difference of a relationship, which is a measure of central tendency. Correlation is a useful tool in understanding the relationship between variables, but it should be used in conjunction with other statistical techniques to provide a comprehensive understanding of the data.

Here for the given question, let us check all the given statements in the options

Here we know that the shape is approximately normal. Then the given option will be false.

Next, it is collection of all samples taken from the population, So the given option will be false

Now, we have to check as the sample size increases, the value of n increases. here n is the value on the denominator of the equation of standard deviation.

Therefore, due to an increase in the value of n, then there will be decreases in the standard deviation.

Then the less standard deviation means a small variance.

Therefore, as a result, as the sample size grows, the variation will be minimal.

So, the center is the same as the sample proportion p.
