Answers

Answer:

Option E - Box plot E

Step-by-step explanation:

Given : Data,

67, 66, 64, 62, 60, 56, 54, 50, 46, 42, 41, 40, 40, 38, 35, 21, 19

To find : Which choice below is a boxplot for the following distribution?

Solution :

Step 1- Arranging the data from lowest to highest,

{19,21,35,38,40,40,41,42,46,50,54,56,60,62,64,66,67}  

Step 2 - Find the median of the data  

As the data is odd numbers so the median is [tex]\frac{n+1}{2}[/tex] th term.

[tex]\frac{n+1}{2}=\frac{17+1}{2}=9th[/tex] term.

9th term is 46

∴ [tex]Q_2=46[/tex]  

Step 3 - To find Upper quartile and lower quartile  

Lower quartile data set is the median of the upper terms from median

{19,21,35,38,40,40,41,42}

Median of the set is [tex]M=\frac{38+40}{2}=39[/tex]

∴ [tex]Q_1=39[/tex]  

Upper quartile data set is the median of the lower terms from median

{ 50,54,56,60,62,64,66,67}

Median of the set is [tex]M=\frac{60+62}{2}=61[/tex]

∴ [tex]Q_3=61[/tex]

In m + 8, the variable m can have any value. Tell whether each statement is true or false. Then explsin your reasoning.

Answers

M can have any value because M can represent any number because it is the unknown.
Final answer:

In algebra, the variable 'm' in the expression 'm + 8' can indeed take on any value; therefore, the statement is true because variables are meant to be placeholders for a wide range of numbers.

Explanation:

In the expression m + 8, it is true that the variable m can have any value, which means that this expression does not impose any restrictions on the possible values of m. This type of statement involving a variable is common in mathematics, particularly in algebra where variables represent unknown quantities that can take on various values.

When evaluating statements for truth or false, the statement 'in m + 8, the variable m can have any value' is true. Variables, by their nature, are symbols that can represent any number, so unless specific limitations are given, we assume variables to have the full set of numbers (real numbers, integers, etc.) as potential values.

The graph of the function f is shown. f(4) =
A) 0
B) 1
C) 4
D) 5

Answers

Let me first give you an overview of the coordinate plane. The coordinate plane has an x-axis that runs horizontally left to right and a y-axis that runs vertically up and down. The axes intersect at a right angle at the origin, which is (0, 0). If you have a point, say (2, 5), then the point is located two steps to the right of the origin and five steps up. Remember to always go left and right first before going up and down. This is because the y-coordinate depends on the x-coordinate.

Sometimes the y-coordinate is called f(x), which is the function value at a given x-value. Again, this is because f(x) depends on the x-value.

The numerical value of f(4) is how ever many steps up or down the graph is (the graph is a visual representation of f(x) points). At x = 4, the graph is at 1, so f(4) = 1.

The answer is 6,500 pounds.

To convert tons to pounds, you can use the conversion factor that 1 ton is equal to 2,000 pounds. So, to convert 3.25 tons to pounds:

Multiply 3.25 tons by 2,000 pounds/ton to get the answer in pounds.3.25 tons * 2,000 pounds/ton = 6,500 pounds.

Therefore, 3.25 tons is equal to 6,500 pounds.

C.


1800π ft2


D.


2940π ft2

Answers

its c or d hope i help

The exact surface area of the cylinder with a radius of 30 ft and height of 19 ft is calculated using the formula 2πr(h + r), resulting in an area of 2940π ft², which matches option D.

To find the exact surface area of a cylinder, we use the formula that states the surface area (SA) is SA = 2πr(h + r), where r is the radius and h is the height of the cylinder. Given that the radius (r) is 30 ft and the height (h) is 19 ft, we plug these values into the formula:

SA = 2π(30)(19 + 30)

SA = 2π30(49)

SA = 60π(49)

SA = 2940π ft²

Therefore, the exact surface area of the cylinder is 2940π square feet, which corresponds to option D.

A monument in the shape of a right triangle sits on a rectangular pedestal that is 5 meters high by 11 meters long. The longest side of the triangular monument measures 61 meters. How high off the ground is the top of the monument?

Answers

Answer:

65 meters off the ground.

Step-by-step explanation:

Final answer:

The height of the monument is 9.80 m

Explanation:

To find the height of the monument, we can use the Pythagorean theorem. The rectangle on the pedestal forms a right triangle with the longest side of the monument being the hypotenuse. Let's call the height of the monument 'h'. Using the Pythagorean theorem, we have:

[tex]h^2 = (11^2) - (5^2)[/tex]

[tex]h^2 = 121 - 25[/tex]

[tex]h^2 = 96[/tex]

[tex]h = \sqrt{96[/tex]

h ≈ 9.80 meters

An artists builds a sculpture out of metal and wood that weighs 14.9 kilograms.3/4 of this weight is metal,and the rest is wood.How much does the wood part of the sculpture weigh?PLZZZ HELP!!!!!!!

Answers

Given is a sculpture that is built up of metal and wood, and the weight of this sculpture is 14.9 kilograms.

It says that three-fourth of the total weight is metal and says to find the weight of wooden part.

We can find the weight of metal part and then subtract it from the total weight to calculate the answer.

Total weight = 14.9 kilograms.

Metal part = three-fourth of total weight = [tex] \frac{3}{4} *14.9=\frac{44.7}{4} =11.175 \;kilograms [/tex]

Wooden part = 14.9 - 11.175 = 3.725 kilograms.

Hence, the wooden part is 3.725 kilograms.

3.725 kilograms or ¹/₄ part

Further explanation

Given:

An artist builds a sculpture out of metal and wood that weighs 14.9 kilograms.

³/₄ of this weight is metal, and the rest is wood.

Question:

How much does the wood part of the sculpture weighs?

The Process:

From the information above, we make a diagram that matches the composition of the sculpture material.

[tex]\boxed{metal}\boxed{metal}\boxed{metal}\boxed{wood} = 14.9 \ kilograms[/tex]

³/₄ of this weight is metal, and the rest is wood, which is [tex]\boxed{ \ 1 - \frac{3}{4} = \frac{1}{4} \ }[/tex].

And now, let us calculate the wood part of the sculpture weighs.

[tex]\boxed{ \ = \frac{1}{4} \times 14.9 \ kilograms \ }[/tex]

Both 4 and 14.9 are multiplied by 10.

[tex]\boxed{ \ = \frac{1}{40} \times 149 \ kilograms \ }[/tex]

[tex]\boxed{ \ = \frac{149}{40}  \ kilograms \ }[/tex]

Both the numerator and denominator are divided by 4.

[tex]\boxed{ \ = \frac{37.25}{10}  \ kilograms \ }[/tex]

[tex]\boxed{ \ = \frac{3,725}{1,000}  \ kilograms \ }[/tex]

[tex]\boxed{\boxed{ \ 3.725 \ kilograms \ }}[/tex]

Thus, the wood part of the sculpture weighs is 3.725 kilograms or ¹/₄ part.

What is 1,289,845 rounded to the nearest ten thousand?

Answers

Final answer:

1,289,845 rounded to the nearest ten thousand is 1,290,000.

Explanation:

To round 1,289,845 to the nearest ten thousand, we need to look at the digit in the ten thousandth place, which is the 8 in this case. If the digit is 5 or greater, we round up, and if it is less than 5, we round down. Since the 8 is greater than 5, we round up. To do this, we keep the digit in the ten thousandth place as it is and change all the digits to the right of it to zeros. Therefore, 1,289,845 rounded to the nearest ten thousand is 1,290,000.

Solve the system of linear equations by substitution.

x=2y+7
3x−2y=3

Answers

The system of equation
First equation
x = 2y + 7
Second equation
3x - 2y = 3

Substitute x with (2y + 7) in the second equation
3x - 2y = 3
3(2y + 7) - 2y = 3

use distributive property
3(2y) + 3(7) - 2y = 3
6y + 21 - 2y = 3

add like terms
6y - 2y + 21 = 3
4y = 3 - 21
4y = -18
  y = -18/4
  y = -4.5

Substitute y with its value, which is -4.5, in the first equation
x = 2y + 7
x = 2(-4.5) + 7
x = -9 + 7
x = -2

The solution is
(x,y) = (-2, -4.5)

Terrence buys a new car for $20,000. The value of the car depreciates by 15% each year. If f(x) represents the value of the car after x years, which function represents the car’s value?

f(x) = 20,000(0.85)x
f(x) = 20,000(0.15)x
f(x) = 20,000(1.15)x
f(x) = 20,000(1.85)x

Answers

The first one: f(x) = 20,000(0.85)^x (make sure you use the carrot thingy when you type these, otherwise you get a linear equation).

If the car is depreciating in value, that means you only have a certain percentage of its value left after a certain amount of time. If you lose 15% of the car's value each time, you're left with 85% of the car's value each time since 15 subtracted from 100 is 85. In order to start this equation, the first time the car depreciates in value, you will be multiplying 20,000 by 0.85 (percentage in decimal form) to determine what the value of the car is after one depreciation. Since this equation is the only one in which 20,000 is multiplied by 0.85, the first equation is correct.

The value of Terrence's car after x years is

A = 20,000 ( [tex]1-0.15)^x[/tex]

What is depreciation?

Subtract the asset's salvage value (what you expect it to be worth at the end of its useful life) from its cost to calculate depreciation using the straight-line technique. The depreciable basis, or the amount that can be depreciated, is the result. Divide this figure by the number of years the asset will be useful.

Depreciation is the rate at which an object's value declines over time.

it is given by the formula,

A = P [tex](1-r)^t[/tex]

where A is the value of object after x period of time, P is the principal amount, r is the rate of depreciation, and t is the for the time period.

Given:

Terrence buys a new car for $20,000,

rate of depreciation = 15%,

We know the formula of the rate of depreciation,

A = P [tex](1-r)^t[/tex]

Here A= $20, 000

r = 15% = 0.15

So, the value of Terrence's car is A = 20,000 ( [tex]1-0.15)^x[/tex].

a number is added to 9. the result is then multiplied by 4 to give a new result of 120. what is the number ?

Answers

Hello there!

A number is added to 9. << Since we don't know the name of the number, we will call it x.

A number is added to 9 = x + 9

Then they say the result is then multiplied by 4 to give a new result of 120.

We need to turn this into an equation.

(x + 9) * 4 = 120

Use the distributive property

(x)(4) + (4)(9) = 120

4x + 36 = 120

Add 36 to both sides

4x + 36 - 36 = 120 - 36

4x = 84

x = 84/4

x = 21

Thus, the number is 21
