Find the mean and the median of this data: 9, 6, 5, 3, 28, 6, 4, 7.

Answer:

Northside

Median: 36

Range: 32

IQR: 17

Southside:

Median: 39

Range: 38

IQR: 22

Step-by-step explanation:

Northside first

Order the ages from least to greatest

24, 28, 32, 32, 32, 36, 41, 44, 49, 49, 56

Median is 36 since it's in the middle

Subtract the greatest number from the smallest number to find the range (56-24) = 32

To find the IQR you need the ages least to greatest

24, 28, 32, 32, 32, 36, 41, 44, 49, 49, 56

Find the lower quarter = 32

Find the upper quarter = 49

Subtract 49 and 32 (49-32) = 17

Southside

The Median is the line at the middle of the box, in this case its between 38 and 40 which is 39.

The range is 61 - 23 = 38 (Greatest - least)

The IQR is 52 - 30 = 22

The equation of the blue line is y = 7x - 8 and the equation of the red line is y = -2x + 2

Equations are written as a function of two or more variables with input and output.

The standard linear equation is given in the form y = mx + b

m is the slope

b is the y-intercept

For the red line, the y-intecept is 2

Using the coordinate point on the red line (0,2) and (1, 0)

Slope = -2/1
Slope = -2

Equation of the  red line is y = -2x + 2

For the blue line, we will use the coordinate points (2, 6) and (1, -1)
m = -7/-1

m = 7

-1 = 7(1) + b

-1 - 7 = b

b = -8

Hence the equation of the blue line is y = 7x - 8

The length of the extension ladder that is against the outside wall of the house is 22.58 feet.

When the ladder lies against a house, a right triangle is formed. The length of the ladder is the hypotenuse. The distance from the base of the ladder to the house is the base. The lenfth off the house is the length.

To find the length of the ladder, Sin would be used:

Sin = opposite / hypotenuse

Sin 77 = 22 / h

h = 22 / 0.9743 = 22.58 feet

Answer:

Volume = 1/3 ft^3

Step-by-step explanation:

volume of prism is multiplying the dimensions

Volume = (1/3 ft)x(2/3ft)x(1 1/2ft)  

Volume = (1/3 ft)x(2/3ft)x( 3/2ft)

Volume = (1x2x3)/(3x3x2) ft^3 = 6/18 ft^3 = 1/3 ft^3

Option B is correct, the volume of the  right rectangular prism is 1/3 cubic feet.

a three dimensional shape can be defined as a solid figure or an object or shape that has three dimensions—length, width, and height.

The given figure is a right rectangular prism.

The length is [tex]1\frac{1}{2}[/tex] feet

The width is 2/3 feet

The height is 1/3 feet.

Volume=Length×width×Height

Intersecting Secant-Tangent Theorem

The square of the tangent is equal to the product of the external secant segment and the secant.

Given:

AE² = EC · ED

⇒ 12² = 8(18 + x)

⇒ 144 = 144 + 8x

⇒ 0 = 8x

⇒ x = 0

ED = 18 + x

     = 18 + 0

     = 18

Answer is equation C

Step-by-step explanation:

They are converting Celsius temperature to Fahrenheit temperature.

F = 1.8C + 32

F = 1.8(0) + 32 = 32 Fahrenheit

F = 1.8(30) + 32 = 86 Fahrenheit

F = 1.8(100) + 32 = 212 Fahrenheit

Answer:

C) F = 1.8C + 32

Step-by-step explanation:

Hello! The easiest way to do this is to substitute the numbers from your table into your possible answer choices until you find numbers that make a true/correct statement.

For A:

F = 32C + 1.8 <== substitute any number for F and C from your table

32 = 32(0) + 1.8 <== multiply

32 = 0 + 1.8 <== add

32 = 1.8

This statement is false/incorrect

For B:

C = 1.8F + 32 <== substitute any number for F and C from your table

0 = 1.8(32) + 32 <== multiply

0 = 57.6 + 32

0 = 89.6

This statement is false/incorrect

For C:

F = 1.8C + 32 <== substitute any number for F and C from your table

32 = 1.8(0) + 32 <== multiply

32 = 0 + 32 <== add

32 = 32

This statement is true/correct

For D:

C = 32F + 1.8 <== substitute any number for F and C from your table

0 = 32(32) + 1.8 <== multiply

0 = 1024 + 1.8 <== add

0 = 1025.8

This statement is false/incorrect

As we can see, the only equation that makes a true statement is C.

Therefore, the correct answer is C.

Approximately 2 gallons will be needed if each gallon of stain and  the project will cost be $73.96 if  each gallon costs $36.98

The formula for calculating the area of a triangle is expressed as:

A = 0.5bh

where

base = 15feet

height = 20feet

Area of the deck = 20 * 15 * 0.5

Area of the deck is  150 square feet

Number of gallons needed  = 350/150 = 2.3

Hence approximately 2 gallons will be needed if each gallon of stain covers a maximum of 350 square feet.

Cost of the two gallons  = 36.98 * 2

Cost of the two gallons  = $73.96

Hence the project will cost be $73.96 if  each gallon costs $36.98

x | -3  -2  -1   0  1

y | 0   -3  -4 -3  0

Step-by-step explanation:

f(x) = x² + 2x - 3

x = -3 then y = (-3)² + 2(-3) - 3 = 9 - 6 - 3 = 3 - 3 = 0

x = -2 then y = (-2)² + 2(-2) - 2 = 4 - 4 - 3 = 0 - 3 = -3

x = -1 then y = (-1)² + 2(-1) - 1 = 1 - 2 - 3 = -1 - 3 = -4

x = 0 then y = (0)² + 2(0) - 3 = 0 + 0 - 3 = 0 - 3 = -3

Step-by-step explanation:

To know which ordered pair is in the solution set of -3x+4y < 20 we first need to identify the x-value in the ordered pair and plug it into the equation. When simplify, on the condition the y-value you get is identical as the y-value in the ordered pair, then that ordered pair is a solution to the equation.

Now let's solve:  

To find the solution of the equation is ordered pair substitute the value of x and y co-ordinate to check set of ordered pair is the solution of the given equation.

Given:

-3x + 4y < 20
