Answer:

y = - x + 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 )

calculate m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (- 2, 6 ) and (x₂, y₂ ) = (4, 0 )

m = [tex]\frac{0-6}{4-(-2)}[/tex] = [tex]\frac{-6}{4+2}[/tex] = [tex]\frac{-6}{6}[/tex] = - 1 , then

y = - x + c ← is the partial equation

to find c substitute either of the 2 points into the partial equation.

using (4, 0 ) , that is x = 4, y = 0

0 = - 4 + c ⇒ c = 0 + 4 = 4

y = - x + 4 ← equation of line

The five number summary of the given data is the minimum value = 20, maximum value = 100, median = 69.5, Q1 = 48, and Q3 = 89.

A number summary consists of five values: the most extreme values in the data set (the maximum and minimum values), the lower and upper quartiles, and the median. In order to find the five number summary,

1. Arrange the given data in ascending order. In the given case, the data is already in ascending order.

2. Determine the minimum and maximum value for the data set. In the given case, the minimum value is 20 and maximum value is 100.

3. Determine the median of the data set. The median refers to the middle number of the data set. If the data is an even set of numbers, the middle two terms are averaged. In the given case, there are 14 numbers, hence the median is an average of 7th and 8th term.

Median = (69 + 70)/2 = 69.5

4. Determine the lower quartile (Q1) and upper quartile (Q3). The Q1 and Q3 are the middle term of the lower and upper range respectively.

For the lower range, 20, 33, 43, 48, 64, 68, 69, the middle term is 48. Hence Q1 = 48.

For the upper range, 70, 72, 83, 89, 96, 99, 100, the middle term is 89. Hence Q3 = 89.

Note: The question is incomplete. The complete question probably is: Find the 5 number summary for the data shown. 20, 33, 43, 48, 64, 68, 69, 70, 72, 83, 89, 96, 99, 100

It will take to complete the entire order of sneakers in 8 days.

To find out how long it will take to complete the entire order of sneakers, you need to multiply the time it takes to complete 1/10 of the order by the total number of orders. Since there are 10 orders in the entire order of sneakers, it will take 10 times as long to complete the entire order as it does to complete 1/10 of the order.

Since it takes 4/5 of a day to complete 1/10 of the order, it will take 4/5 * 10 = 8 days to complete the entire order. Therefore, the answer is 8 days.

The quadratic function answer for 2(x^2-3x+6) is 4x^2 - 6x + 12.

I believe that is correct

Answer:

y = 4/5x + 3

Step-by-step explanation:

If two lines are parallel to each other, they have the same slope slopes.

The first line is y = 4/5x + 2. Its slope is 4/5. A line parallel to this one will also have a slope of 4/5.

Plug this value (4/5) into your standard point-slope equation of y = mx + b.

y = 4/5x + b

To find b, we want to plug in a value that we know is on this line: in this case, it is (5, 7). Plug in the x and y values into the x and y of the standard equation.

7 = 4/5(5) + b

To find b, multiply the slope and the input of x (5)

7 = 4 + b

Now, subtract 4 from both sides to isolate b.

3 = b

Plug this into your standard equation.

y = 4/5x + 3

This equation is parallel to your given equation (y = 4/5x + 2) and contains point (5, 7).

First, let's calculate the theoretical probability. There are a total of 36 tiles in the bag, and 10 of them are blue, so the theoretical probability of drawing a blue tile is 10/36, or about 27.78%.

Now let's calculate the experimental probability. In the five trials, you drew a total of 236 tiles, and a total of 75 blue tiles. So the experimental probability of drawing a blue tile is 75/236, or about 31.86%.

In this problem we must determine the cosine of the double angle and half angle based on the exact values of the cosine of an angle and the quadrant location of the angle.

Cosine is a function between - 1 and 1 and whose period is 2π (360°), positive when angle is either on first quadrant (0 < θ < 0.5π) or on fourth quadrant (1.5π < θ < 2π). In addition, sine function is positive on first quadrant and negative on fourth quadrant.

The required trigonometric formulas in terms of trigonometric function cos θ are described below:

sin θ = √(1 - cos² θ)

cos 2θ = cos² θ - sin² θ

cos 0.5θ = ± √ [(1 + cos θ) / 2]

First, determine the exact value of sine:

sin θ = - √[1 - (3 / 5)²]

The value of the sales tax will be 1.21. Sales tax is a fee that is charged in addition to the cost of products and services. We have to use basic percentage mathematics concepts.

Let's first try to understand what is sales tax.

The government levies a consumption tax known as a sales tax on the purchase of goods and services. At the point of sale, a standard sales tax is imposed, collected by the shop, and paid to the government. A company is liable for sales taxes in a particular jurisdiction if it has a nexus there, which, depending on the local rules, can be a physical location, an employee, an affiliate, or some other presence.

Sales taxes typically take a portion of the cost of the items sold. For instance, a city's residents might pay a total of 7.5% in sales taxes if the state levies a 4% rate, the county 2%, and the city 1.5%. However, frequently certain things—like food—are exempt or are exempt if they fall below a specific amount, such as apparel purchases under $200. Additionally, many products are subject to additional taxes known as excise taxes. A type of excise tax known as a "sin tax" is the $1.50 municipal excise tax that New York City imposes per pack of 20 cigarettes in addition to the $4.35 state excise tax.

In this Question, The bill before tax and tip was $17.35.

The sales tax was $1.22 and the total amount of the bill including the tip was $18.57.

The total cost of the meal before tax and tip was $17.35. The sales tax rate for the area was 7%. To calculate the sales tax, we must first determine the pre-tax cost of the meal multiplied by the tax rate.

Formula:

Sales Tax = Pre-tax cost × Tax Rate

Calculation:

Sales Tax = $17.35 × 0.07

Sales Tax = $1.22

This means that the sales tax amount was $1.22. Vani tipped 18% on the amount after the sales tax was added. To calculate the total amount of the bill after tip, we must first add the sales tax to the pre-tax cost of the meal.

Formula:

Total Cost = Pre-tax cost + Sales Tax

Calculation:

Total Cost = $17.35 + $1.22

Total Cost = $18.57

We can then calculate the tip amount by multiplying the total cost of the meal by the tip rate.

Formula:

Tip = Total Cost × Tip Rate

Calculation:

Tip = $18.57 × 0.18

Tip = $3.35

Therefore, the sales tax was $1.22 and the total amount of the bill including the tip was $18.57.

The percentage by which the price of the car went up from the original price is 60% (third option)

The first step is to determine the price of the car after the percentage increase. Percentage is the fraction of a number as a value out of 100. The sign that is used to represent percentage is %.

Price of the car after the percentage increase = (1 + percent increase/100) x original cost of the car

Price of the car after the percentage increase = (1 + 20/100) x 20,000

Price of the car after the percentage increase = (1 + 0.2) x 20,000

Price of the car after the percentage increase = 1.2 x 20,000 = $24,000

Price after the $8,000 increase = $24,000 + 8,000 = $32,000

As a result, the percentage is one part in one hundred. "Per 100" is short for "per percent." It is represented by the symbol "%".

Given spends of George from monthly income,

let monthly income be x

spends on food = 5/8 of salary

spends on food = 5x/8

amount left = x - 5x/8 = 3x/8

spends on fees = 1/6 of remainder

amount left = 3x/8 - x/16 = 5x/16

spend on contingencies = 2/3 of remainder
