The solution of the inequality −2(−3x+4) − 5 > −3(x+7) − 19 is x > -3.

Inequalities are mathematical expressions involving the symbols >, <, ≥ and ≤.

Therefore, let's solve the inequality as follows:

−2(−3x+4) − 5 > −3(x+7) − 19

let's open the brackets on both sides

−2(−3x+4) − 5 > −3(x+7) − 19

6x - 8 - 5 > -3x - 21 - 19

6x - 13 > -3x - 40

add 13 to both sides of the inequality

6x - 13 > -3x - 40

6x - 13 + 13 > -3x - 40 + 13

6x > -3x - 27

add 3x to both sides of the inequality

6x + 3x > -3x + 3x - 27

9x > -27

divide both sides by 9

x > -27 / 9

Hence,

x > -3

The bottom plot takes into account the domains and removes parts of each piece (the dashed gray parts) outside their respective domains.

To calculate the weekday without code, use the formula: w = (day + int(2.6 * \(month_num\) - 0.2 * century - 2 * (cm - 1) + year + year // 4 + cm // 4)) % 7. Convert the numeric weekday value (0-6) to the weekday name (Sunday-Saturday). For example, July 1, 2023, is a Saturday.

Without writing any code, you can perform the following steps to determine the weekday:

1. Determine the modified century (cm):

  - Divide the year by 100 to get the century.

  - If the month is either January or February and the century is divisible by 4, subtract 1 from the century. Otherwise, use the original century.

2. Convert the month name to the corresponding month number:

  - Assign a number to each month: January = 1, February = 2, March = 3, and so on.

3. Calculate the weekday using the formula:

  - Use the formula: w = (day + int(2.6 * \(month_num\) - 0.2 * century - 2 * (cm - 1) + year + year // 4 + cm // 4)) % 7.

  - Here, w is the numeric value for the weekday, ranging from 0 (Sunday) to 6 (Saturday).

4. Convert the weekday number to the weekday name:

  - Assign a name to each weekday: 0 = Sunday, 1 = Monday, 2 = Tuesday, and so on.

For example, let's find the weekday of July 1, 2023:

1. Determine the modified century:

  - Year = 2023, Century = 20, cm = 20 - 1 = 19.

2. Convert the month name to the month number:

  - July corresponds to month number 7.

3. Calculate the weekday using the formula:

  - w = (1 + int(2.6 * 7 - 0.2 * 20 - 2 * (19 - 1) + 2023 + 2023 // 4 + 19 // 4)) % 7

  - w = (1 + int(18.2 - 4 - 36 + 2023 + 505 + 4)) % 7

  - w = (1 + int(2512.2)) % 7

  - w = 1 + 2512 % 7

  - w = 1 + 5

  - w = 6

4. Convert the weekday number to the weekday name:

  - The weekday is Saturday.

Therefore, July 1, 2023, falls on a Saturday.

There are 6 pairwise comparisons that need to be made in order to gain a complete understanding of which treatment effects differ significantly from others.

In order to determine which treatment effects differ significantly from others, we need to make pairwise comparisons between all possible pairs of treatment groups. Let's consider an example with four treatment groups labeled A, B, C, and D.

To determine which treatment effects differ significantly from others, we need to compare the mean scores of each treatment group with the mean scores of every other treatment group. This means we need to make the following pairwise comparisons:

A vs B

A vs C

A vs D

B vs C

B vs D

C vs D

Therefore, there are 6 pairwise comparisons that need to be made in order to gain a complete understanding of which treatment effects differ significantly from others.

It's worth noting that when making multiple pairwise comparisons, there is an increased risk of making a Type I error (i.e., rejecting the null hypothesis when it is actually true) due to the multiple testing problem. To control for this, researchers may choose to adjust the significance level or use methods such as the Bonferroni correction to adjust the p-values of the individual tests.

Volume is a three-dimensional scalar quantity. The volume of the water that Marry should pour into the vase is 241.28 cubic inches.

A volume is a scalar number that expresses the amount of three-dimensional space enclosed by a closed surface.

Given the radius of the flower vase is 4 inches, while the height of the vase is 6 inches, therefore, the total volume of the vase is,

Volume = πR²×H = π× 4²×6 = 301.6 in³

Since the volume of the vase is 301.6 in³, but the store has told her to fill the vase 4/5 of its capacity, therefore, the volume of water Marry should pour is,

Volume of water = (4/5) × 301.6 in³ = 241.28 cubic inches

Hence, the volume of the water that Marry should pour into the vase is 241.28 cubic inches.

The smallest possible inside length of the cubical steel tank that can hold 275 liters of water is approximately 0.640 meters.

The side length of the cube is found by converting the volume of water from liters to cubic meters, as the unit of measurement for the side length is meters.

Given that the volume of water is 275 liters, we convert it to cubic meters by dividing it by 1000 (1 cubic meter = 1000 liters):

275 liters / 1000 = 0.275 cubic meters

Since a cube has equal side lengths, we find the side length by taking the cube root of the volume. In this case, we find the cube root of 0.275 cubic meters:

∛(0.275) ≈ 0.640

Rounded to the nearest 0.001 meters, the smallest possible inside length of the tank is approximately 0.640 meters.

Step-by-step explanation:

This question requires reverse thinking. This type of problem is usually presented like 13,500 people are there to start with and it increases by 6.5 yearly, how much will it be in a year? But this time we have to find the years and we have the end population value.

First write equation:

13,500(0.065)^x = 27000

Simplify by dividing:

0.65^x = 0.5

*Use property of log (for isolating x):

x(log(0.65)) = log(0.5)

Isolate x:

x = log(0.5)/log(0.65)

x = 1.6090405507426917

*the reason why we did log was because we need the x to not be in an exponent for but to be normal. So log makes us able to write it like that. Same works with ln or natural log. For continuously compounding or continuously depreciating you would use ln.

A researcher would use a t-test when comparing two means to determine statistical significance. So, the statement "The researcher uses a t-test when comparing two means to determine statistical significance" is TRUE.

A t-test is a statistical method for assessing the difference between two population means from two independent samples.

It is frequently used in hypothesis testing and statistical analysis in order to determine whether a study result is statistically significant or not.

A t-test compares two means and calculates a t-value, which is then used to calculate the p-value.

The p-value indicates the likelihood that the observed difference between the two means is due to random variation, rather than a genuine difference between the populations being compared.

If the p-value is less than the predetermined significance level (usually 0.05), then the difference between the means is considered statistically significant.

It would take approximately 11.7 years to pay off the credit card balance of $3052.41 with a monthly payment of $55 and an annual interest rate of 18%.

To calculate the time it will take to pay off a credit card balance, we need to consider the interest rate, the balance, and the monthly payment. In your question, you mentioned an annual interest rate of 18% and a monthly payment of $55.

First, let's convert the annual interest rate to a monthly interest rate. We divide the annual interest rate by 12 (the number of months in a year) and convert it to a decimal:

Monthly interest rate = (18% / 12) / 100 = 0.015

Next, we can calculate the number of months it will take to pay off the balance. Let's assume there are no additional charges or fees added to the balance:

Balance = $3052.41

Monthly payment = $55

To determine the time in months, we'll use the formula:

Number of months = log((Monthly payment / Monthly interest rate) / (Monthly payment / Monthly interest rate - Balance))

Using this formula, the calculation would be:

Number of months = log((55 / 0.015) / (55 / 0.015 - 3052.41))

Calculating this equation gives us approximately 140.3 months.

Since we want to find the number of years, we divide the number of months by 12:

Number of years = 140.3 months / 12 months/year ≈ 11.7 years

Therefore, it would take approximately 11.7 years to pay off the credit card balance of $3052.41 with a monthly payment of $55 and an annual interest rate of 18%.
