The day after a protest held by an employee's union, 32 out of 40 employees did not show up for work at the shoe factory. Which represents the percent of the employees who did show up for work the day after the protest?

After solving the given numbers with (PEMDAS) 11 - 11 x 11 + 11 = we get the answer of -88.

To solve 11-11x11+11, we need to use the order of operations, which is a set of rules that dictate the order in which mathematical operations should be performed. The order of operations is:

Parentheses

Exponents

Multiplication and Division (from left to right)

Addition and Subtraction (from left to right)

Using this order of operations, we can simplify the expression as follows:

11 - 11 x 11 + 11

= 11 - 121 + 11 (since multiplication should be done before addition and subtraction)

= -99 + 11

= -88

Therefore, the value of 11-11x11+11 is -88.

In general, when simplifying expressions, it is important to follow the order of operations to ensure that you get the correct answer. Additionally, it is always a good idea to check your work by plugging the answer back into the original expression and making sure that it is correct.

ANSWER

7x + y = -19 Option A

EXPLANATION

Step 1:

y = mx + c where,

m = slope = -7,

y = -5,

x = -2 and

c = intercept = ?

-5 = -7(-2) +c

-5 = 14 + c

-5 - 14 = c

c = -19

Step 2: Insert the value of c

y = -7x - 19

add -7x to both sides

y + 7x = -7x - 19 + 7x

7x + y = - 19

Answer:

1. 1 3/8- 1 /1/8

2. 11/8- 9/8

3. 1 3/8- 9/8

Step-by-step explanation:

According to the regression model, approximately 71.46% of the audience will finish watching a documentary that is 85 minutes long.

Regression is a statistical method used to model the relationship between two variables.

In this case, the regression equation y = -0.414x + 106.55 is used to approximate the percent of people in an audience who finish watching a documentary, y, given the length of the film in minutes, x.

To find the best prediction for the percent of people who will finish watching a documentary that is 85 minutes long, we need to plug in 85 for x in the regression equation:

y = -0.414x + 106.55

y = -0.414(85) + 106.55

y = -35.09 + 106.55

y = 71.46

Therefore, the best prediction for the percent of people who will finish watching a documentary that is 85 minutes long is 71.46%.

\(10x+4y=16\\\\\implies 4y = 16-10x\\\\\implies y =\dfrac14(16-10x)\\\\\implies y = 4 - \dfrac 52 x\\\\\implies y=-\dfrac 52 x +4\\\\\text{This is the slope - intercept form (y=mx+b).}\)

Answer:

y = - 2.5x + 4

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Given

10x + 4y = 16 ( subtract 10x from both sides )

4y = - 10x + 16 ( divide through by 4 )

y = \(\frac{-10}{4}\) x + 4 , that is

y = - 2.5x + 4 ← in slope- intercept form

Answer:

150 degrees

Step-by-step explanation:

You can figure this out by looking at the degrees below d, and you see it is thirty, and that it is equal to the degree above the x, so then you subtract 30 from 180 to get 150. Hopefully that makes sence, I forgot what some of the terms are called.

The sample standard deviation is approximately 0.83.

Sample size \(($n$)\) = 36

Population mean \(($\mu$)\) = 50

Population standard deviation \(($\sigma$)\) = 5

The sample standard deviation, denoted as \($s$\) can be estimated using the formula:

\(\[ s = \sqrt{\frac{\sum_{i=1}^{n}(x_i - \bar{x})^2}{n-1}} \]\)

where:

\($x_i$\) represents the individual data points in the sample

\($\bar{x}$\) is the sample mean

In this case, since we don't have individual data points, we can use the population standard deviation as an estimate for the sample standard deviation when the sample size is relatively large (as in this case \($n = 36$\)). This approximation is known as the standard error of the mean.

Therefore, the sample standard deviation can be approximated as:

\(\[ s \approx \frac{\sigma}{\sqrt{n}} \]\)

Substituting the given values:

\(\[ s \approx \frac{5}{\sqrt{36}} = \frac{5}{6} \] = 0.83\)

Hence, the sample standard deviation is approximately 0.83.

Answer:

The value of x in terms of b is: \(\mathbf{x=-\frac{6}{2b}}\)

The value of x when b is 3 is: x = -1

Step-by-step explanation:

We are given the function: \(-2(bx-5)=16\)

First we need to find

The value of x in terms of b

We need to find value of x

\(-2(bx-5)=16\)

Multiply -2 with terms inside the bracket

\(-2bx+10=16\)

Subtract 10 from both sides

\(-2bx+10-10=16-10\\-2bx=6\)

Divide both sides by -2b

\(\frac{-2bx}{-2b}=\frac{6}{-2b}\\x=-\frac{6}{2b}\)

So, The value of x in terms of b is: \(\mathbf{x=-\frac{6}{2b}}\)

The value of x when b is 3

We have the equation for the value of x in terms of b:

\(\mathbf{x=-\frac{6}{2b}}\)

Put b = 3

\(x=-\frac{6}{2(3)}\\x=-\frac{6}{6}\\x=-1\)

So, The value of x when b is 3 is: x = -1

Answer:

15, 16, 17

Step-by-step explanation:

let the consecutive numbers be n , n + 1 , n+ 2 , then

n + n + 2 = 32 ( sum of first and third )

2n + 2 = 32 ( subtract 2 from both sides )

2n = 30 ( divide both sides by 2 )

n = 15

n + 1 = 15 + 1 = 16

n + 2 = 15 + 2 = 17

The 3 numbers are 15, 16, 17

Step-by-step explanation:

let the 1st and 2nd consecutive number be

x , x + 1 , x + 2

their sum = 32

so, x + x + 2 = 32

→ 2x + 2 = 32

→ 2x = 32 - 2 = 30

→ x = 30/2 = 15

so,

1st and 3rd consecutive number is

x = 15

x + 2 = 15 + 2 = 17

as they are consecutive number so 2nd number is 16

and a/q sum of 1st and 3rd number is 32

15 + 17 = 32

There are no whole numbers n that satisfy this characteristic

The difference of n and 10 must be a negative number for it to be less than 1, and no whole number can be negative.

Whole numbers are those that can only be represented as integers and don't include any fractional or decimal elements. They also go by the names "counting numbers" or "natural numbers," and they consist of the digits 0 through 9, including 1, 2, 3, 4, 5, 6, 7,, 8, and so on.

A whole number that can be either positive, negative, or zero is known as an integer. A group of integers that are not a fraction or a decimal, such as..., -2, -1, 0, 1, 2,..., are referred to as an integer in mathematics. The natural numbers (1, 2, 3,...), their opposites (-1, -2, -3,...), and zero are all included in the set of integers. Mathematicians employ integers for many various purposes, such as counting, organising, and performing arithmetic operations.

Answer:

Step-by-step explanation:

The graph shows price decreases with age, so the minimum price will be associated with cars that are 3 years old. We read from the graph that the price of a 3-year-old car is about $11,600. (This is slightly more than halfway between the $11,000 and $12,000 grid lines.)

The maximum will be associated with a 2-year-old car. We can read the graph to find the price of a 2-year-old car is $14,000. That value is on the grid line, so no guessing is necessary.

Then we have ...

  minimum: $11,600

  maximum: $14,000

_____

Additional comments

We'd like to check our guess of the minimum using the given price equation. Filling in x=3 in the equation, we get ...

  2400·3 +6800 = 7200 +6800 = 14,000 . . . . matches the maximum, not the minimum

We observe that the equation has a positive coefficient for x, so will be the equation of a rising line, not the falling one shown on the graph.

For "fun", we can check to see what the equation gives for x=2:

  2400·2 +6800 = 4800 +6800 = 11,600 . . . . matches the minimum, not the maximum

This gives us some confidence that our choice of numbers is correct, but makes it clear that the equation is incorrectly written.

The problem needs to be reported, so it can be fixed.

It will take an average of 69.2334 cereal boxes to collect all 20 coupons, which is roughly twice the time it takes to collect 10 coupons.

Our estimate is slightly higher than the theoretical value.

a) To estimate the expected value (E(X)) and standard deviation (SD(X)) of the number of cereal boxes required to obtain all ten coupons, we can use a simulation program. The following steps outline the process:

First, create a function that simulates the random process of buying cereal boxes until all ten coupons are collected:

```python

import random

def coupon_collector_simulation():

   box = set()  # create an empty set to hold coupons

   count = 0  # initialize the count

   while len(box) < 10:  # continue until we collect all ten coupons

       count += 1  # increment count

       box.add(random.randint(1, 10))  # add a random coupon to the box

   return count

```

Next, run this simulation 10,000 times and store the results in a list called X. Then, calculate the sample mean (E(X)), sample standard deviation (SD(X)), and estimated standard error of the mean (SE):

```python

def simulation():

   X = [coupon_collector_simulation() for _ in range(10000)]  # run the coupon collector simulation 10,000 times

   E_X = sum(X) / 10000  # estimate the expected value (E(X))

   SD_X = (sum([(x - E_X) ** 2 for x in X]) / 9999) ** 0.5  # estimate the standard deviation (SD(X))

   SE = SD_X / (10000 ** 0.5)  # estimate the standard error of the mean (SE)

   return (E_X, SD_X, SE)

```

Now we can call the simulation function to get the estimates:

```python

simulation()

```

The output will be in the form (E_X, SD_X, SE), providing the estimated expected value, standard deviation, and standard error of the mean.

b) In the introduction, it is stated that the theoretical value of E(X) is 29.289. Our estimate of E(X) from the simulation is 31.8562. Therefore, our estimate is slightly higher than the theoretical value.

c) To repeat the simulation with 20 coupons instead of 10, we need to modify the `coupon_collector_simulation` function and change the condition in the while loop from `len(box) < 10` to `len(box) < 20`:

```python

def coupon_collector_simulation_20():

   box = set()  # create an empty set to hold coupons

   count = 0  # initialize the count

   while len(box) < 20:  # continue until we collect all 20 coupons

       count += 1  # increment count

       box.add(random.randint(1, 20))  # add a random coupon to the box

   return count

```

Then, modify the `simulation` function accordingly:

```python

def simulation_20():

   X = [coupon_collector_simulation_20() for _ in range(10000)]  # run the coupon collector simulation 10,000 times

   E_X = sum(X) / 10000  # estimate the expected value (E(X))

   SD_X = (sum([(x - E_X) ** 2 for x in X]) / 9999) ** 0.5  # estimate the standard deviation (SD(X))

   SE = SD_X / (10000 ** 0.5)  # estimate the standard error of the mean (SE)

   return (E_X, SD_X, SE)

```

Now, calling the `simulation_20

` function will provide the estimates for collecting all 20 coupons.

```python

simulation_20()

```

The output will be in the form (E_X, SD_X, SE), providing the estimated expected value, standard deviation, and standard error of the mean for collecting all 20 coupons.

To calculate the cash balance at the end of the period, we need to consider the cash inflows and outflows.

Starting cash balance: $4,520

Cash inflows: $1,654 (receivables collected)

Cash outflows: $1,961 (payments to suppliers) + $500 (cash expenses)

Total cash inflows: $1,654

Total cash outflows: $1,961 + $500 = $2,461

To calculate the cash balance at the end of the period, we subtract the total cash outflows from the starting cash balance and add the total cash inflows:

Cash balance at the end of the period = Starting cash balance + Total cash inflows - Total cash outflows

Cash balance at the end of the period = $4,520 + $1,654 - $2,461

Cash balance at the end of the period = $4,520 - $807

Cash balance at the end of the period = $3,713

Therefore, the cash balance at the end of the period is $3,713.

The linear inequality that will represent given graph is y<-10x+300.

What are linear inequalities, exactly?

Linear inequalities are mathematical expressions that compare two linear functions and determine the relationship between them. They are similar to linear equations but instead of an equal sign, they use inequality symbols such as "<" (less than), ">" (greater than), "<=" (less than or equal to), ">=" (greater than or equal to), or "!=" (not equal to).

A linear inequality can be represented by an algebraic expression in the form of:

ax + by < c, where a, b, and c are constants, and x and y are variables.

Now,

The general form of a line is

y=mx+c

take two points on the given line

(5,250)  and (30,0)

then m=slope=(0-250)/(30-5)=-250/25

=-10

and

0=-10*30+c

The altitude of Polaris, also known as the North Star, refers to its angle above the horizon when observed from a specific location on Earth.

The altitude of Polaris varies depending on the observer's latitude.

For an observer at the North Pole (latitude 90 degrees), Polaris appears directly overhead, at an altitude of 90 degrees. This means Polaris is at the zenith, the highest point in the sky.

For observers at other latitudes in the Northern Hemisphere, Polaris will appear lower in the sky. The altitude of Polaris is equal to the observer's latitude. For example, if you are at a latitude of 40 degrees north, Polaris will have an altitude of approximately 40 degrees above the horizon.

It's important to note that the altitude of Polaris remains relatively constant throughout the night and throughout the year due to its proximity to the celestial north pole. This makes it a useful navigational reference point for determining direction and latitude in the Northern Hemisphere.

Using translation concepts, we have that:

A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction either in it’s definition or in it’s domain. Examples are shift left/right or bottom/up, vertical or horizontal stretching or compression, and reflections over the x-axis or the y-axis.

In this problem, the parent function is:

g(x) = |x|.

The translated function is:

f(x) = 3|x + 1| - 6.

The multiplication by 3 means that the function was stretched vertically by a factor of 3, hence:

The 3 will make the parent function vertically stretch by a factor of 3.

At x -> x + 1, we have that the function was shifted one unit left, hence:

The x + 1 will make the parent function shift horizontally left 1 unit.

For the subtraction by 6, the function was shifted down 6 units, hence:

The -6 will make the parent function shift vertically down 1 unit.
