If a divides b and a divides c, then a divides (bm + cn).

To prove that if a divides b and a divides c, then a divides (bm + cn), we can use the properties of divisibility.

Given:

a|b, which means b is divisible by a.

a|c, which means c is divisible by a.

We want to show that a|(bm + cn), which means (bm + cn) is divisible by a.

By definition, if a divides b, then there exists an integer k₁ such that b = ka. Similarly, if a divides c, there exists an integer k₂ such that c = ka.

Now, let's substitute these expressions into (bm + cn):

(bm + cn) = (ka)m + (ka)n

= kam + kan

= a(km + kn)

We can see that (bm + cn) can be written as a times the integer (km + kn). Since (km + kn) is an integer, this implies that (bm + cn) is divisible by a.

Therefore, if a divides b and a divides c, then a divides (bm + cn).

Explanation:

Given the function that models the total chacrge of a company as T = 35.00 + 18.75m where;

T is the total charges,

m is the number of months of storage

Given

T = $260.00

we are to find the value of m

Substitute

260 = 35 + 18.75m

18.75m = 260 - 35

18.75m = 225

m = 225/18.75

m = 12

Hence it will take 12 months to cost a new custimer $260.00

Answer:

\((\frac{10}{3}, 1)\)

Step-by-step explanation:

1) In order to solve a system of equations with the elimination method, you need to add or subtract the two equations and "eliminate" variables by canceling out terms. This leaves you with an equation with only one variable to solve. Then, once you solve that equation, you can substitute the answer you got into one of the system's equations to find either the x or y value.

This problem already has one 3x in each equation, so let's focus on canceling that term out, eliminating the x variable. To set up this situation, we need one 3x to be negative, so let's multiply the terms in 3x-6y = 4 by -1, which gets us to -3x + 6y = -4. Now let's "cancel out" those x variables by adding them together.  (This work is shown in the first picture.)

Remember to add the other terms. This leaves us with the equation 13y = 13. By isolating y, we can find its value, which leaves us with y = 1.

2) Next, let's substitute 1 for y in one of the two equations. In this case, I used 3x + 7y = 17. Then, isolate x to find its value:

\(3x + 7 (1) = 17\\3x + 7 = 17 \\3x = 10 \\x = \frac{10}{3}\)

Therefore, the answer would be \((\frac{10}{3} , 1)\).

HOW DO I START?

Don't worry, you know that this problem only has two small steps, and it's done, it should take less than 45 seconds to complete.

WE ALWAYS WANT TO ISOLATE THE VARIABLE TO FIND Y: MAKE IT BE ALONE!

STEP 1: Subtract 12 from both sides, to start getting 5y alone.

NOW YOU HAVE: 5y = 20

STEP 2: Divide by 5 from both sides, to get the Y fully alone.

NOW YOU HAVE: y = 4

The statement that is not correct is "analyst can decrease the probability of making both type i and type ii errors by decreasing the population size."

This statement is incorrect because the probability of making a type I or type II error is not affected by the population size, but rather by the significance level and power of the statistical test being a used. Increasing the sample size can help decrease the probability of making both types of errors by increasing the power of the test, but decreasing the population size will not have any effect on the error probability.

The two numbers are x = 3.43 and y = 22.57.

What is a linear equation in two variables?

An equation is said to be a linear equation in two variables if it is written in the form of ax + by + c=0, where a, b & c are real numbers and the coefficients of x and y, i.e a and b respectively, are not equal to zero.

Let the first number be x and the second number be y. Then we can write the given information as a system of equations:

x + y = 26

(2/5)x + (3/8)y = 10

To solve this system, we can eliminate one of the variables by multiplying the first equation by 8 and the second equation by 5, then subtracting the resulting equations:

8x + 8y = 208

10x + 15y = 50

Subtracting these equations gives us:

-2x - 7y = -158

Dividing both sides by -7, we get:

x + y = 22.57

Substituting this back into the first equation, we get:

x + 22.57 = 26

Solving for x, we get:

x = 26 - 22.57

= 3.43

Substituting this back into the original equation x + y = 26, we get:

3.43 + y = 26

Solving for y, we get:

y = 26 - 3.43

= 22.57

Hence, the two numbers are x = 3.43 and y = 22.57.

The price of the watch before the discount is calculated to be £24.44.

As the total price of the watch and a pair of trainers is £53. 55 and the price of the trainer before the discount was £38, we first calculate the price of the trainers after the discount as follows;

discount on a pair of trainers = 15/100 × 38 =  £5.7

cost of trainers after discount =  £38 - 5.7 =  £32.3

Now the price of the watch after the discount can be calculated by subtraction as follows;

price of watch after discount = total price - price of trainers after discount

price of watch after discount =  £53. 55 - £32.3

price of watch after discount = £21.25

Now the price of the watch before the discount can be calculated as follows;

price of watch before discount = £21.25 × 15/100

price of watch before discount = £21.25 + £3.1875

price of watch before discount = £24.44

Answer:

The standard form of a linear equation is Ax + By = C. When we want to find the slope of the line represented by this equation, we have two options. We can put the equation in slope-intercept form and identify the slope that way, or we can use the formula m = -A/B.

Step-by-step explanation:

The equation of the line in standard form that passes through the point (2, -3) and has a slope of 4 is 4x - y = 5.

To write the equation of a line in standard form (Ax + By = C) that passes through the point (2, -3) and has a slope of 4, we can use the point-slope form of the equation:

y - y1 = m(x - x1)

where (x1, y1) is the given point (2, -3) and m is the slope (which is 4 in this case). Substitute the values into the equation:

y - (-3) = 4(x - 2)

Now, simplify:

y + 3 = 4x - 8

Next, bring all the terms to the left side of the equation to get the standard form:

4x - y = 8 - 3

Finally, simplify the constant term:

4x - y = 5.

The answer is "The IQR is the best measure of variability, and it equals 7. because the best measure of variability for the data is the IQR, and its value is 7

A linear function is defined as a function that has either one or two variables without exponents. It is a function that graphs to a straight line.

The given plot displays the distribution of the number of roses purchased per day at a grocery store. The best measure of variability for this data would be the interquartile range (IQR) since it is robust to outliers and provides a measure of the spread of the middle 50% of the data.

To calculate the IQR, we need to find the first quartile (Q1) and the third quartile (Q3). Q1 is the median of the lower half of the data, and Q3 is the median of the upper half of the data.

From the plot, we can see that there are a total of 11 data points: one at 1, two at 2, three at 6, three at 7, two at 8, and three at 9. The median (Q2) is 7 since it is the middle value when the data are arranged in order.

To find Q1, we need to find the median of the lower half of the data. Since there is one data point below 6 and three data points at 6, the lower half of the data consists of four points: 1, 2, 6, and 6. The median of this set is (1+2)/2 = 1.5.

To find Q3, we need to find the median of the upper half of the data. Since there are two data points at 8 and three data points at 9, the upper half of the data consists of five points: 8, 8, 9, 9, and 9. The median of this set is (8+9)/2 = 8.5.

Therefore, the IQR is Q3-Q1 = 8.5-1.5 = 7.

Therefore, the answer is "The IQR is the best measure of variability, and it equals 7. because the best measure of variability for the data is the IQR, and its value is 7

The expression data.index(20) evaluates to c) 1.

The expression data.index(20) is used to find the index position of the value 20 within the list data. In this case, data refers to the list [10, 20, 30].

When the expression is evaluated, it searches for the value 20 within the list data and returns the index position of the first occurrence of that value. In this case, the value 20 is located at index position 1 within the list [10, 20, 30]. Therefore, the expression data.index(20) evaluates to 1.

The list indexing in Python starts from 0, so the first element of a list is at index position 0, the second element is at index position 1, and so on. In our case, the value 20 is the second element of the list data, so its index position is 1.

Therefore, the correct answer is option c) 1.

It's important to note that if the value being searched is not present in the list, the index() method will raise a Value Error exception. So, it's a good practice to handle such cases by either using a try-except block or checking if the value exists in the list before calling the index() method.

The intergration of ∫2ln(x)xdx is ln(x)x^2 + x^2 + C (Option d)

To evaluate the integral ∫2ln(x)xdx, we can use integration by parts.

Let's assume u = ln(x) and dv = 2x dx. Then, we can find du and v using these differentials,

du = (1/x) dx

v = ∫dv = ∫2x dx = x^2

Using the formula for integration,

∫u dv = uv - ∫v du

we have:

∫2ln(x)xdx = uv - ∫v du

= ln(x) * (x)^2 - ∫(x)^2 * (1/x) dx

= ln(x) * (x)^2 - ∫x dx

= ln(x) * (x)^2 - (1/2) * (x)^2 + C

The function "all Three(social, grades, sleep)" initializes an empty list, iterates over social, grades, and sleep lists, checks if names are present in both, appends them, and returns the list.

To write the function "all_three(social, grades, sleep)", you can use the following steps:

1. Initialize an empty list called "all_students" to store the students who appear in all three lists.

2. Use a for loop to iterate over each student name in the "social" list.

3. Within the loop, check if the student name is present in both the "grades" and "sleep" lists using the "in" operator.

4. If the student name is found in both the "grades" and "sleep" lists, append it to the "all_students" list.

5. After the loop, return the "all_students" list.

Here's the code implementation for the function:

def all_three(social, grades, sleep):
   all_students = [ ]
   for student in social:
       if student in grades and student in sleep:
           all_students.append(student)
   return all_students
