Add 2b + 2b

bring down the -4 and 5

4b - 4=5

4b= 5+4

Add 5 + 4=9

4÷4b=9÷4 -Divide n both side

cancel the 4 sense their the same and bring down the B

Divide 9 and 4

Step-by-step explanation:

Solve for  x by simplifying both sides of the equation, then isolating the variable.

The table has a greater rate of change.

The rates of change are equal.

In the given problem, we have a table showing the relationship between x and y values. By comparing the change in y with the change in x, we can determine the rate of change. Looking at the table, we observe that for every increase of 1 in x, there is a corresponding increase of 1 in y. Therefore, the rate of change for this table is 1.

The slopes are equal.

The equation has a greater slope.

In problem 2, we are given a linear equation in the form y = mx + b, where m represents the slope. The given equation is y = 2x + 7, which means the slope is 2. To compare the rates of change, we compare the slopes. If the slopes are equal, the rates of change are equal. In this case, the slopes are equal to 2, so the rates of change are the same.

The function rule has a greater slope.

The slopes are equal.

In problem 3, we are told that as x increases by 1, y increases by 3. This information gives us the rate of change between x and y. The slope of a function represents the rate of change, and in this case, the slope is 3. Comparing the slopes, we find that they are equal, as both have a value of 3. Therefore, the rates of change are the same.

The coefficient of x^5 is the term (x^5)/5!, and 5! = 120, the coefficient of x^5 is 0.

The Maclaurin series is a series of polynomial terms that are used to approximate a function in a neighborhood of the origin. The general form of the Maclaurin series is a summation of a function's derivatives at 0. The coefficient of x^5 in the Maclaurin series generated by f(x) = sinx is 0. This can be seen by the formula for the Maclaurin series of sinx:

sinx = x - (x^3)/3! + (x^5)/5! - (x^7)/7! + ...

Since the coefficient of x^5 is the term (x^5)/5!, and 5! = 120, the coefficient of x^5 is 0.

Therefore, the rank of matrix 'a' in this case would be 5.

To find the rank of a matrix, we need to perform row reduction to obtain its row echelon form (REF) or reduced row echelon form (RREF). However, since the matrix 'a' is not provided, I cannot perform the calculations or determine its rank.

The rank of a matrix is equal to the number of non-zero rows in its row echelon form or reduced row echelon form. If the system of equations 'ax = 0' has a two-dimensional solution space, it means that the rank of matrix 'a' is less than the number of columns (6) but greater than 4 (since the solution space is two-dimensional).

In hypothesis testing, the null hypothesis (H0) is a statement that there is no significant difference between two groups, or that a certain parameter is equal to a specified value. In this case, the null hypothesis is that the mean difference is 0, meaning there is no significant difference between the two groups being compared.

The alternative hypothesis (Ha), on the other hand, is a statement that contradicts the null hypothesis. It can be one-tailed (directional), indicating that the mean difference is greater than or less than 0, or two-tailed (non-directional), indicating that the mean difference is not equal to 0. So, to determine the null and alternative hypotheses in this case, we know that the null hypothesis is that the mean difference is 0. The alternative hypothesis can be either one of the following:
- Ha: The mean difference is not equal to 0 (two-tailed)
- Ha: The mean difference is greater than 0 (one-tailed)
- Ha: The mean difference is less than 0 (one-tailed)

Answer:

12 hours

Step-by-step explanation:

Let x hours be the time it will take you to mow the greens at the golf course.

Since Kim can mow twice as fast, it will take Kim x / 2 hours to mow the greens.

In 1 hour, you will mow 1 / x of the greens

in 1 hour, Kim will mow 1 / (x / 2) of the greens= 2 / x of the greens

In 4 hours, you will mow 4 * 1 / x of the course = 4 / x of the greens

In 4 hours, Kim will mow 4 * 1 / (x / 2) of the course = 4 / (x / 2) = 8 / x of the greens.

Since we are dealing in fraction, the sum of the amount of greens that they would individually mow in 4 hours should be 1. i.e

(4 / x) + (8 / x) = 1

12 / x = 1

Solve for x;

x = 12

Therefore, it will take you 12 hours to mow the greens alone.

The correct equation in slope-intercept form is:

y= 6x+14

Step-by-step explanation:

Given the equation

y-2=6(x+2)

y-2 = 6x+12

Adding 2 to both sides

y-2+2=6x+12+2

y= 6x+14

Thus, the correct equation in slope-intercept form is:

y= 6x+14

1) WHAT WAS YOUR MISTAKE

In the 2nd step, you had added 4 to the right-hand side of the equation instead of 2. The reason is that both sides should have been added by 2. But, you mistakenly added 4 to the right-hand side of the equation instead of 2.

2) SUGGESTION TO AVOID MISTAKE

You must make sure not to disturb the balance of two sides of the equation, meaning whatever the operation (add/subtract, multiply or divide) you do, you make sure to do the same operation on both sides of the equation.

The probability that the sample mean will be 0.54 or larger, given a population mean of 0.5, can be calculated using statistical techniques.

To calculate the probability, we need additional information about the distribution of distances, such as the standard deviation or the sample size. The probability can be determined using the central limit theorem if the sample size is large enough or if the population distribution is approximately normal.

Assuming the population distribution is approximately normal or the sample size is large, we can use the z-score formula to calculate the probability. The z-score measures the number of standard deviations a particular value is from the mean. In this case, we want to calculate the probability of obtaining a sample mean of 0.54 or larger, given a population mean of 0.5.

First, we calculate the z-score using the formula:

z = (sample mean - population mean) / (standard deviation / sqrt(sample size))

Without information about the standard deviation or sample size, we cannot calculate the z-score or the probability. If you provide these additional details, I can assist you further in calculating the probability.

Answer:

10 routes to her home with a stop at the library

Using the relation between velocity, distance and time, it is found that a reasonable estimation of the current is of 1 mph.

Velocity is distance divided by time, hence:

\(v = \frac{d}{t}\)

Upstream, against the current, he traveled 3 miles in t hours, hence the equation is:

\(2 - c = \frac{3}{t}\)

\(c = 2 - \frac{3}{t}\)

Downstream, with the current, he traveled 3 miles in 4 - t hours, hence the equation is:

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

Hence:

\(c = \frac{3}{4 - t} - 2\)

Then, taking the two equal equations:

\(2 - \frac{3}{t} = \frac{3}{4 - t} - 2\)

\(\frac{3}{4 - t} + \frac{3}{t} = 4\)

\(\frac{3t + 12 - 3t}{t(4 - t)} = 4\)

12 = -4t² + 16t

4t² - 16t + 12 = 0

t² - 4t + 3 = 0

(t - 3)(t - 1) = 0.

The current is positive, hence:

\(c = 2 - \frac{3}{3}\)

c = 2 - 1

c = 1 mph.

The most accurate way to find probability is option (b) statistical probability,

When dice are irregular, meaning that the sides are not equal in size or weight, the most accurate way to determine the probability of a certain side (such as 5) landing up is by using statistical probability.

Statistical probability, also known as empirical probability, is based on observed data and experimental results.

In this case, one would conduct multiple trials of rolling the irregular dice and record the frequency of the specific side (5) landing up.

By analyzing the collected data, the observed frequency can be used to estimate the probability of the event occurring.

Using statistical probability allows for a more accurate determination of the probability because it takes into account the actual outcomes observed in real-world trials.

This approach acknowledges the inherent irregularities of the dice and incorporates them into the estimation of the probability.

On the other hand, a priori probability is based on theoretical knowledge or assumptions, and it may not accurately reflect the actual probabilities when dealing with irregular dice.

Subjective probability relies on personal judgments and beliefs, which may introduce biases and may not be as reliable as observed data.

Therefore, the most accurate way to determine the probability of a specific side landing up on an irregular dice is to use statistical probability.

which is based on empirical observations and actual trial results.
