Answer:

41.9%

Step-by-step explanation:

percent change = (new number - old number)/(old number) × 100%

new number = 44

old number = 31

percent change = (44 - 31)/31 × 100%

percent change = 13/31 × 100%

percent change = 0.41935 × 100%

percent change = 41.9%

The solution to the equation 2⁽ᵐ ⁺ ¹⁾ = 16⁽ᵐ ⁺ ⁷⁾ is m = -9.

Given the equation the question:

2⁽ᵐ ⁺ ¹⁾ = 16⁽ᵐ ⁺ ⁷⁾

To solve the equation 2⁽ᵐ ⁺ ¹⁾ = 16⁽ᵐ ⁺ ⁷⁾  using the equal base method, we can rewrite 16 as a power of 2:

2⁽ᵐ ⁺ ¹⁾ = 16⁽ᵐ ⁺ ⁷⁾

2⁽ᵐ ⁺ ¹⁾ = 2⁴⁽ᵐ ⁺ ⁷⁾

2⁽ᵐ ⁺ ¹⁾ = 2⁽⁴ᵐ ⁺ ²⁸⁾

Now that both sides have the same base, we can equate their exponents and solve for m:

m + 1 = 4m + 28

4m - m = 1 - 28

3m = -27

m = -9

Therefore, the value of m is -9.

If Jace took a taxi from his house to the airport and the taxi company charged a pick-up fee of $4. 40 plus $2. 25 per mile and the total fare was $53. 90, not including the tip, the distance traveled by Jace is 22 miles.

Let the miles traveled by Jace be x

According to the question,

The total cost of the travel = pick-up fee + fare per mile

Pick-up fee = $4. 40

Fare per mile = $2. 25 per mile

Total fare = $4. 40 + x ($2. 25)

According to the question,

Total fare = $53. 90

We get the following equation,

$4. 40 + x ($2. 25) = $53. 90

4.40 + 2.25x  = 53.90

2.25x = 53.90 - 4.40

2.25x = 49.50

x = 49.50 ÷ 2.25

Answer:

  x < 2/3

Step-by-step explanation:

You want to solve the 2-step inequality 3x +7 < 9.

If the coefficient of the variable is positive, the two steps to solving the inequality are identical to the two steps for solving a "2-step" equation.

Isolate the variable term by subtracting the unwanted constant with it.

  3x +7 -7 < 9 -7

  3x < 2

Divide by the coefficient of the variable.

  3x/3 < 2/3

  x < 2/3 . . . . . . the solution

Additional comment

If the number you divide by (or multiply by) is negative, the sense of the inequality is reversed. For example, ...

  -2x < 6

  x > -3 . . . . . . divide by negative 2 and reverse the inequality symbol

This comes about because multiplying by a negative number changes the ordering.

  -2 < -1

  2 > 1

Some functions change ordering, too, so care must be taken when functions (or inverse functions) are applied to an inequality.

During these two years, Emile's height increased by 0.9 cm or 9/10 cm.

We will calculate the change in Emile's height using Subtraction. The formula that we will use is:

Change in height = Eighth-grade height - Seventh-grade height

Firstly, we will convert the height to a fraction.

Seventh-grade height = ((10×3)+7)/10

Seventh-grade height = 37/10 cm

Now,

Eighth-grade height = ((5×4)+3)/5

Eighth-grade height = 23/5 cm

Now, find the change in height by substituting the values in the formula.

Change in height = Eighth-grade height - seventh-grade height

                             =   23/5 - 37/10

Change in height = 23×2 - 37/10

Change = 46 - 37/10

The length of the field is 21.5 meters

The width of the field is 10.75 meters

If "w" is the width, then the length is 43 - 2w.

As the area of the rectangular field = length × width

= w(43 - 2w)

Area = [tex]43w - 2w^2[/tex]

the vertex of the x coordinate is w and this is a quadratic equation.

w = [tex]-b/2a[/tex]

Here a = -2 and b = 43

w = .[tex]-43/2(-2)[/tex]

w = [tex]-43/4[/tex] = -10.75

So the width of the field is 12.25 meters.

The length of the filed = 43 - 2(10.75) = 21.5

Area = 10.75 × 21.5 = 231.125 square meters.

The field has an area of 228.

Therefore, the length must be 21.5 meters and the width must be 10.75 meters.

Step-by-step explanation:

the denominator of f(x) cannot be zero as this would make f(x) undefined.

Equating the denominator to zero and solving gives the value that x cannot be and if the numerator is non zero for this value then it is a vertical asymptote.

2x + 6 = 0 ( subtract 6 from both sides )

2x = - 6 ( divide both sides by 2 )

x = - 3

Thus x = - 3 is a vertical asymptote of f(x)

To get another estimate using the velocities at the end of the time periods, repeat the process from (a), but this time, use the velocity values at the end of each interval as the heights of the rectangles.

To estimate the distance traveled by the motorcycle, we can use the velocities at the beginning or end of the time intervals to calculate the area under the velocity graph using rectangles.

(a) Using the velocities at the beginning of the time intervals, we can estimate the distance by adding up the areas of the rectangles formed by the velocity and time intervals. The distance estimate is the sum of these areas, which is approximately 156 meters.

(b) Using the velocities at the end of the time intervals, we can estimate the distance by adding up the areas of the rectangles formed by the velocity and time intervals. The distance estimate is the sum of these areas, which is approximately 175 meters.

(c) Since the velocity function is increasing over time, the estimate in part (a) using the velocities at the beginning of the time intervals is a lower estimate, and the estimate in part (b) using the velocities at the end of the time intervals is an upper estimate. This is because the velocity is increasing, and the rectangles using the beginning velocities will underestimate the distance, while the rectangles using the end velocities will overestimate the distance. Therefore, we can conclude that the estimates in parts (a) and (b) are respectively lower and upper estimates of the distance traveled by the motorcycle.

(a) To estimate the distance traveled using the velocities at the beginning of the time intervals, use the velocity values as the heights of rectangles and multiply them by the interval width (12 seconds). Sum up the resulting products to get an approximate distance.

(b) To get another estimate using the velocities at the end of the time periods, repeat the process from (a), but this time, use the velocity values at the end of each interval as the heights of the rectangles.

(c) The estimates in parts (a) and (b) can be considered as upper and lower estimates if the velocity function is strictly increasing or decreasing. If the velocity function is neither increasing nor decreasing consistently, then these estimates are not strictly upper or lower estimates. To determine which is which, analyze the given data and observe the behavior of the velocity function over time.

This count includes the empty set, so there are 256 - 1 = 255 non-empty spacy subsets of {1, 2, 3, ..., 12}. To solve this problem, we can use a combination of counting and logical reasoning.

First, let's consider the smallest possible spacy subset of {1, 2, 3, ..., 12}. It must contain one of the integers 1, 2, or 3, but not any of the others in that sequence. The same is true for the next set of three integers, 4, 5, and 6, and so on. Therefore, we can break down the problem into smaller subproblems by considering subsets that start with each of the integers 1 through 10.

For example, let's consider subsets that start with 1. If a spacy subset contains 1, it cannot contain 2 or 3. It can, however, contain any of the other integers from 4 through 12. Therefore, there are 8 possible integers that can be included in such a subset. Similarly, if a spacy subset starts with 2, it can contain any of the integers 5 through 12, giving us 8 possible integers again. If a subset starts with 3, it can contain any of the integers 6 through 12, giving us 7 possible integers.

We can continue this process for each of the possible starting integers, and count up the number of possible subsets. The total number of spacy subsets of {1, 2, 3, ..., 12} is then the sum of these subproblems.

Starting with 1: 8 possible integers
Starting with 2: 8 possible integers
Starting with 3: 7 possible integers
Starting with 4: 7 possible integers
Starting with 5: 7 possible integers
Starting with 6: 6 possible integers
Starting with 7: 6 possible integers
Starting with 8: 6 possible integers
Starting with 9: 5 possible integers

Given that jobs arrive at a processor according to a Poisson distribution with an average arrival rate λ (per minute), we can calculate the probability of observing a specific number of jobs arriving in a given time interval using the Poisson probability formula:

P(X = k) = (e^(-λ) * λ^k) / k!

In your expression, we have the following terms: (201) (1 + 20λ + (20λ)^2 / 2! + (20λ)^3 / 3! + ... + (20λ)^9 / 9!). This expression is actually the expansion of the Poisson probability formula for k=0 to k=9, with a specific arrival rate λ = 20.

In all these cases, no interaction means that the variables act independently on the response variable Y, and their combined effects are simply additive rather than multiplicative or otherwise interdependent.

No interaction in modeling response variable Y and explanatory variables X and Z means that the effect of each explanatory variable on the response variable is independent of the other explanatory variable. This can be illustrated using graphs or tables as follows:

a. When all variables are continuous (multiple regression), no interaction means that the slope of Y on X is constant regardless of the level of Z, and the slope of Y on Z is constant regardless of the level of X. In other words, the effect of X on Y is the same for all levels of Z, and the effect of Z on Y is the same for all levels of X.

b. When Y and X are continuous, and Z is categorical (analysis of covariance), no interaction means that the mean difference in Y between each level of Z is the same for all levels of X. In other words, the effect of Z on Y is the same for all levels of X.

c. When Y is continuous, and X and Z are categorical (two-way ANOVA), no interaction means that the mean difference in Y between each combination of X and Z is the same. In other words, the effect of X on Y is the same for all levels of Z, and the effect of Z on Y is the same for all levels of X.

d. When Y is binary, and X and Z are categorical (logistic regression), no interaction means that the odds ratio of Y on X is the same for all levels of Z, and the odds ratio of Y on Z is the same for all levels of X. In other words, the effect of X on the odds of Y is the same for all levels of Z, and the effect of Z on the odds of Y is the same for all levels of X.

a. Multiple regression (All variables are continuous): No interaction means that the effect of one explanatory variable (X) on the response variable (Y) does not depend on the value of the other explanatory variable (Z). In a graph, this would be represented by parallel lines or planes when plotting Y against X for different values of Z.

b. Analysis of covariance (Y and X are continuous, Z is categorical): No interaction suggests that the relationship between Y and X is consistent across different levels of the categorical variable Z. In a graph, this would appear as parallel regression lines for each category of Z.

c. Two-way ANOVA (Y is continuous, X and Z are categorical): No interaction means that the effect of one categorical variable (X) on the response variable (Y) is not influenced by the levels of the other categorical variable (Z). In a table, this would be evident by having similar differences between cell means across all combinations of X and Z.

d. Logistic regression (Y is binary, X and Z are categorical): No interaction implies that the odds of the binary response variable (Y) occurring do not depend on the combined effect of X and Z. In a table, the odds ratios for different levels of X and Z should be consistent, indicating no interaction between the two categorical variables.

In all these cases, no interaction means that the variables act independently on the response variable Y, and their combined effects are simply additive rather than multiplicative or otherwise interdependent.
