The unit price of the pair of socks is $7.99

Unit price can be described as the price of one item. In this case scenario, we are looking for the unit price of a pair of socks.

The unit price can be calculated as follows

6 pair=47.94

1 pair = x

Cross multiply both sides

6x= 47.94

Divide both sides by the coefficient of x which is 6

6x/6= 47.94/6

x= 7.99

Hence the unit price is $7.99

Answer: P = 50x + 100

Step-by-step explanation: P is the total amount that you pay, 50x is the amount per hour plus the flat rate of 100 that you are guaranteed to pay.

Hope this helps.

The equation of the amount of pay and the number of hours it takes to get your car fixed will be P = 50x + 100.

A relationship between two or more parameters that, when shown on a graph, produces a linear model. The degree of the variable will be one.

You had to take your car to the shop for a weird noise. The mechanic charges a flat rate of $100 for looking at your car and $50 an hour to fix the problem.

Let P represents the amount of pay and x be the number of hours. Then the linear equation is given as,

P = 50x + 100

The equation of the amount of pay and the number of hours it takes to get your car fixed will be P = 50x + 100.

The downloads that would give you a profit of $30,000 the next month is 700 download.

From the information, the profit was given by P(x)=-0.5x²+400x-6,000.

The number of downloads that would give you a profit of $30,000 the next month will be:

P(x)= -0.5x² + 400x - 6,000.

If  a package contains 12 resistors, 3 of which are defective. If 4 are selected, the probability of getting

a) 0 defective resistors: 0.3164

b) 1 defective resistor: 0.4219

c) 3 defective resistor: 0.0469

First step is to calculate the probability for a defective resistor and non-defective resistor:

Probability=3/12

Probability =0.25

Non-defective resistor:

Probability=(1-0.25)

Probability=0.75

Now  let find the probabilities for defective resistors from 0 to 3

P(0)=1(0.75)^4 ×(0.25)^0

P(0)=0.3164

P(1)=4(0.75)^3× (0.25)^1

P(1)=0.4219

P(2)=6(0.75)^2× (0.25)^2

P(2)=0.2109

P(3)=4(0.75)^0×(0.25)^3

P(3)=0.0469

P(4)=1(0.75)^0 × (0.25)^4

P(4)=0.0039

Hence,

a. P(0)=0.3164

b. P(1)=0.4219

c. P(3)=0.0469

Therefore If  a package contains 12 resistors, 3 of which are defective. If 4 are selected, the probability of getting 0 defective resistors: 0.3164, 1 defective resistor: 0.4219, 3 defective resistor: 0.0469.

Answer:

Step-by-step explanation:

I calculated it, I can guarantee that this is the correct answer.

The dimensions of the rectangular  page will be 11.02 inches in width and 7.35 inches in height so that the least amount of paper is used.

Given that,

The area of the rectangular print = 81 square inches

The margins at the top of the page = 1inches, and

The margins at the bottom of the page  = 1inches,

And,

The margins on each side = 1(1/2) inches wide.

Now,

Let, the width of the print = x

And,

The height of the print = y

Now,

According to the question,

The width of the page = x + (1.5 + 1.5) = x + 3

And,

The height of the page = y + (1 + 1) = y + 2

Now,

i.e.

xy = 81

we get,

y = (81/x)

Now,

The area of the page (A) = (x + 3)(y + 2) = (x + 3) [(81/x) + 2],

Now,

For the least amount of paper to be used,

dA/dx = (x + 3) [(81/x) + 2]

We get,

dA/dx = [(81/x) + 2] + (x + 3) [-81/x²] = 0

[(81+2x)/x] = [(x + 3) * 81]/x²        

81 + 2x² = 81x + 243

2x² = 243

We get,

x = 11.02 inch

So,

y = 81/x = 81/11.02 = 7.35 inch

Hence we can say that the dimensions of the rectangular page will be 11.02 inches in width and 7.35 inches in height so that the least amount of paper is used.

What is the slope intercept form of a line ?

The equation of line that can be written as y = mx + c, where m is the slope and c is the line's y-intercept, is known as a slope intercept form.

1.

It is given that equation is : y = 2/5x - 3.

So , the slope here is 2/5 and a parallel line will have the same slope.

We know that the slope intercept form of a line is :

y = mx + c

Put , slope(m) = 2/5 in above equation.

Given , (1,-1) i.e., x = 1 and y = -1

Now we substitute these values to find value of c.

-1 = 2/5(1) + c

-1 = 2/5 + c

-1 - 2/5 = c

(-5 - 2)/5 = c

-7/5 = c

Putting m = 2/5 and c = -7/5 , we get :

So, the equation of parallel line is :

y =  [tex]\frac{2}{5}[/tex] x - [tex]\frac{7}{5}[/tex]

2.

We know that the product of the slope of two perpendicular lines is -1.

Given that equation is : y = -2/5x - 4 i.e., slope = -2/5

So , slope of a line perpendicular to this line is -1/(-2/5) = 5/2

And this line passes through the point (-3,1).

Equation of a line that passes through a point (x1 , y1) and slope (m) is :

(y-y1) = m (x-x1)

Here ;

x1 = -3 , y1 = 1 and m = 5/2

So , the equation of perpendicular line will be :

(y - 1) = [tex]\frac{5}{2}[/tex] (x - (-3))

(y - 1) =  [tex]\frac{5}{2}[/tex] (x + 3)

y - 1 =  [tex]\frac{5}{2}[/tex] x + [tex]\frac{15}{2}[/tex]

y =  [tex]\frac{5}{2}[/tex] x + [tex]\frac{15}{2}[/tex] + 1

y =  [tex]\frac{5}{2}[/tex] x + [tex]\frac{13}{2}[/tex]

Therefore , the answers are :

1. The equation of line parallel to y =  [tex]\frac{2}{5}[/tex] x - 3 will be y =  [tex]\frac{2}{5}[/tex] x - [tex]\frac{7}{5}[/tex] .

2. The equation of line perpendicular to y = - [tex]\frac{2}{5}[/tex] x - 4 will be y =  [tex]\frac{5}{2}[/tex] x + [tex]\frac{13}{2}[/tex] .

s = 2m

A group of equations comprising one or more variables is known as a system of equations. The variable mappings that satisfy each component equation, or the points where all of these equations cross, are the solutions of systems of equations.

We shall employ the linear combination method to resolve a system of three equations in three variables. This time, we will solve for the third variable while eliminating the second variable using the equations that follow from the elimination of the first.

Given the number of small drinks by the vendor is s , number of medium drinks is m and the number of large drinks is g.

The vendor sold all three drinks total of 1385, hence the equation:

∴ s + m + g = 1385.

Each small drink costs 1.15 , medium drinks cost 1.75 and large drinks cost 2.25, hence the equation:

∴ 1.15 s + 1.75 m + 2.25 g = 2238.75

He sold twice as many small drinks as medium drinks, hence the equation:

∴ s = 2m

The system of equations is given by:
