He give the delivery person a tip of 2.1%

What is delivery ?

Transporting items from a source point to a predetermined destination is known as delivery. Roads, railroads, shipping lanes, and airline networks all play major roles in the delivery of cargo (physical products). Specialized networks, such as pipelines for liquid products, power grids for electrical power, computer networks like the Internet, or broadcast networks for electronic information, may be used to distribute specific sorts of goods. [1] A specific subcategory is car transport, and an associated variation is autorack, which involves shipping cars through railroad.

Delivery, which comprises both transportation and distribution, is a crucial aspect of trade and commerce.Distribution is the overall process of providing things, while logistics is the study of efficient delivery and disposition procedures for both persons and materials. Distributors are companies that specialize in moving commercial items from their site of manufacture or storage to their point of sale, whereas delivery services are companies that focus on moving goods to consumers. Deliveries of goods for both commercial and private purposes are also made by postal, courier, and moving services.

According to the question

The new refrigerator delivered to his home for $950

tip he gave to the delivery person = $20

let tip he gave to the person in percentage be x

$20=  [tex]\frac{x}{100}(950)[/tex]

x =[tex]\frac{20(100)}{950}[/tex]

x=2.1%

Thus the tip is 2.1%

a rational number is a type of real numbers, which is in the form of p/q where q is not equal to zero.

Let a/b and c/d represent two rational numbers. This means a, b, c, and d are integers, and b and d are not 0. The product of the numbers is ac/bd, where bd is not 0. Both ac and bd are integers, and bd is not 0. Because ac/bd is the ratio of two integers, the product is a rational number

Given the point:

(0, 6)

Let's find the quadrant and the axis where the point is located.

We have:

(x, y) ==> (0, 6)

The x-coordinate of the point is 0, while the y-coordinate of the point is 6.

Here, the point (0, 6) lies on the y-axis.

Also, since the x-coordinate is 0, we can say the point lies in between quadrant I and quadrant II.

From the graph above we can see the point (0, 6) is between quadrant I and II, and the point lies on the y-axis.

ANSWER:

• The point is in beween Quadrant I and II

• The point lies on the y-axis.

The probability (P) can be gotten as follows:

Each coin has a 1/2 = 0.5 probability of getting a tail. Thus, to get the probability of the 5 coins is:

Then the probability for a tail to emerge

2x + 4y = 20

when y = 0

2x + 4(0) = 20

2x = 10

Divide both-side of the equation by 2

x = 10

Hence, it lies on the point 2x + 4y = 20

Answer:

Explanation:

The formula for calculating binomial probability is expressed as

P(x) = nCx * p^x * q^(n - x)

where

n is the number of trials

x is the number of successes

p is the probability of success

q is the probability of failure

From the information given,

n = 9

p = 0.3

q = 1 - p = 1 - 0.3 = 0.7

By using a binomial probability calculator,

P(x ≥ 2) = 0.804

Answer:

75%

Step-by-step explanation:

Divide 48 by 36:

36/48=

(12*3)/(12*4)=

3/4=0.75

Multiply the decimal by 100 to get the percent:

0.75*100=75%

The workers present on the certain day given is 75%

A percentage is a number that tells us how much out of 100 and can also be written as a decimal or a fraction.

Given that, There are 48 employees in a company. On a certain day, 36 were present.

To find the percentage of workers present = present/totalx100

= 36/48x100

= 75

Hence, The workers present on the certain day given is 75%

Answer:

B. A = 6s²

E. V = (4/3)πr³

Explanation:

A formula describes a function that is nonlinear if the exponent of the variable is greater than 1.

Therefore, the geometric formulas that describe functions that are nonlinear:

A = 6s²

V = (4/3)πr³

Because the variable s has an exponent equal to 2 for the first one and the variable r has an exponent equal to 3 for the second one.

Answer:

C. 54

Explanation:

The triangles ABD and ACD are congruent by SAS (Side - angle - side) becuase

AD is congruent to itself

∠ADB = ∠ADC

BD is congruent to CD

So, the length of AB is equal to the length of AC and we can write the following equation

AB = AC

4x + 6 = 5x - 6

Solving for x, we get:

4x + 6 + 6 = 5x - 6 + 6

4x + 12 = 5x

4x + 12 - 4x = 5x - 4x

12 = x

Then, the length of AB is

AB = 4x + 6

AB = 4(12) + 6

AB = 48 + 6

AB = 54

Therefore, the answer is

C. 54

Slope intercept form (general)

y = mx + b

Where:

m= slope

b= y-intercept

m = 5/3

y = 5/3x + b

Replace ( x,y ) by the given point (2/3,-3/5) and solve for b.

-3/5 = 5/3 (2/3) + b

-3/5 = 10/9 + b

-3/5 - 10/9 = b

b = -77/45

y = 5/3x - 77/45

The equation of a line in the slope-intercept form is y = mx + b, where "m" is the slope and b is the y-intercept.

To find the equation of the line given two points (x, y), follow the steps below.

Step 01: Substitute the point (-3, 2) in the equation.

To do it, substitute x by -3 and y by 2.

Isolate b by adding 3m to both sides of the equation.

Step 02: Substitute b in the equation of the line.

Knowing that b = 2 + 3m. Then,

Step 03: Substitute the point (-6, -2) in the equation from step 02.

To do it, substitute x by -6 and y by -2.

Isolate "m" by subtracting 2 from both sides.

Finally, divide both sides by -3:

Knowing "m", use the equation from step 1 to find "b".

Step 04: Find "b".

Substituting m by 4/3 and solving the equation:

Answer

The perimeter of the triangle is 48.298 units

Explanation

The triangle has the vertices (-9, -5), (-6, 1) and (5, 8).

To find the perimeter of the triangle, we need to find the lengths of the sides of the triangle. The perimeter is the sum of all its sides.

Each side will be calculated from the distance between the vertices.

The distance between two points with the coordinates (x₁, y₁) and (x₂, y₂) is given as

d = √[(x₂ - x₁)² + (y₂ - y₁)²]

The sides of the triangle will be between

(-9, -5) and (-6, 1)

(-9, -5) and (5, 8)

(-6, 1) and (5, 8)

(x₁, y₁) and (x₂, y₂) is (-9, -5) and (-6, 1)

x₁ = -9

y₁ = -5

x₂ = -6

y₂ = 1

d = √[(-6 - (-9))² + (1 - (-5))²]

d = √[(-15)² + (6)²]

d = √(261)

d = 16.155

(x₁, y₁) and (x₂, y₂) is (-9, -5) and (5, 8)

x₁ = -9

y₁ = -5

x₂ = 5

y₂ = 8

d = √[(5 - (-9))² + (8 - (-5))²]

d = √[(14)² + (13)²]

d = √(365)

d = 19.105

(x₁, y₁) and (x₂, y₂) is (-6, 1) and (5, 8)

x₁ = -6

y₁ = 1

x₂ = 5

y₂ = 8

d = √[(5 - (-6))² + (8 - 1)²]

d = √[(11)² + (7)²]

d = √(170)

d = 13.038

The perimeter of the triangle is thus given as

Perimeter = 16.155 + 19.105 + 13.038

= 48.298 units
