What would the height need to be for this curve to be a
density curve?
O 1/5
O 1/4
O 1/2
O 1
Answer: A
Step-by-step explanation:
The total area would have to be 1, so (1/2)(5)(height)=1
2.5height = 1
height = 1/2.5 = 2/10 = 1/5
The height for the density curve will be 1/5. The correct option is A.
What is a density curve?The area under the curve represents 100% of all probabilities. Because we normally use decimals in probabilities, we can also say that the area is equal to 1 (because 100% is a decimal). The density curve shown above depicts how body weights are distributed.
The image of the triangle is showing the base 5 units. For the density curve, the area under the curve must be 1. The height of the curve will be calculated as,
Area = 1
1/2 x B x H = 1
1/2 x 5 x H = 1
2.5 x H = 1
H = 1 / 2.5
H = 1 / 5
Therefore, the height will be 1 / 5.

The cross section of rectangular prism A measures 1. 5 units by 1 unit. The cross section of triangular prism B has a base that measures 2 units and a height of 1. 5 units. If the length of each prism is 1. 81 units, which statement is true? rectangular prism A , with a cross-section that is parallel to its respective basetriangular prism B, with a cross-section that is parallel to its respective base Volume B = one half(Volume A) Volume B = one third(Volume A) Volume B = Volume A Volume B = 2(Volume A).
Volume of an object is the measure of the space that object occupies. The correct comparison of volume of considered objects is: Volume of A = Volume of B
How to find the volume of a right rectangular prism?Suppose that the right rectangular prism in consideration be having its dimensions as 'a' units, 'b' units, and 'c' units, then its volume is given as:
[tex]V = a\times b \times c \: \rm unit^3[/tex]
How to find the volume of right triangular prism?It can be obtained by multiplying the cross sectional triangle's area to the height of the considered triangular prism.
Thus, for the given case, we get:
Volume of rectangular prism:Its dimensions are 1.5 units by 1 units by 1.81 units
Thus, [tex]V_A = 1.5 \times 1 \times 1.81 = 1.5 \times 1.81 = 2.715 \: \rm unit^3[/tex]
Volume of triangular prism:Its cross section triangle has base of 2 units and height of 1.5 unit. The height of the prism is equal to the height of the considered rectangular prism = 1.81 units,
Thus,
[tex]V_B = \text{Area of triangular cross-section} \times 1.81 = \dfrac{1}{2} \times 2\times 1.5 \times 1.81 \: \rm unit^3\\V_B = 2.715\: \rm unit^3\\\\[/tex]
Thus, we get [tex]V_A = V_B[/tex]((Volume of A = Volume of B)

Caroline needed to get her computer fixed. She took it to the repair store. The technician at the store worked on the computer for 2. 75 hours and charged her $114 for parts. The total was $320. 25. Write and solve an equation which can be used to determine xx, the cost of the labor per hour.
Answer:
$75 an hour - (320.25 - 114) / 2.75
Step-by-step explanation:
First, we have to deduct the amount for parts ($114) from the total ($320.25). Once we find the diffrence (206.25), we can divide it by the amount of hours it took (2.75). This leaves us with the answer, $75 an hour.

A person 2 m tall casts a shadow 10 m long. At the same time, a building casts a shadow 80 m long. How tall is the building ?
Answer:
The building is 16 m tall.
Step-by-step explanation:
x/2 = 80/10
10x=160
10x/10 = 160/10
x=16
Answer:
this is a ratio question. The answer is 16 m
Step-by-step explanation:
The persons height to shadow length ratio is 2 : 10
We want to know what the height of the building is when the shadows length is 80.
Let H represent height:
Persons ratio:
2 : 10
Buildings ratio:
H : 80
In other words for every 2 meters height a 10 m shadow is casted so we want to know how many of this ratio can fit into the building:
Let’s find the equivalent ratio:
80/10=8
That means 8 of the persons ratio makes up the building. Let’s find the height of building by 2*8=16.
therefore the building is 16m tall.

The sum of 2 numbers is 32. Their difference is 30. What are the 2 numbers? Show all work
Answer:
31 and 1
Step-by-step explanation:
let the first number be x
let the second number be y
x + y = 32 ---------- eq 1
x - y = 30 ---------- eq 2
eq 1 - eq 2
(x - x) + (y -(-y)) = 32 - 30
y + y = 2
2y = 2
y = 1
Substitute the value of y in eq 1
x + y = 32
x + 1 = 32
x = 32 - 1
x = 31
Therefore the first number is 31 and the second number is 1

The number of the rolls of wrapping paper will be one. Then the correct option is A.
What is division?Division means the separation of something into different parts, sharing of something among different people, places, etc.
If I have a roll of wrapping paper that measures 1446 square in.
If a regular roll of wrapping paper is 30 inches by 60 inches.
The area of the regular roll will be
Area = 30 x 60
Area = 1800 square in
Then the number of rolls of wrapping paper that I have will be
⇒ 1800/1446

A player chooses one card from Deck A and one card from Deck B. What is the probability that the player will choose a C2 card from the first deck or a C6 card from the second deck?
The probability of choosing a C3 card from Deck A or choosing a C5 card from Deck B is
(Use a simplified fraction to represent the probability).
Probabilities are used to determine the chances of events
The probability that the player will choose a C2 card from the first deck or a C6 card from the second deck is 17/42The probability that the player will choose a C3 card from the first deck or a C5 card from the second deck is 9/14How to calculate the probabilityThere are 4 C2 cards in the first deck out of a total of 12 cards, and there are 3 C6 cards in the second deck out of a total of 14 cards.
So, the probability that the player will choose a C2 card from the first deck or a C6 card from the second deck is:
[tex]P = \frac{4}{12} + \frac{3}{14}[/tex]
Simplify
[tex]P = \frac{1}{3} + \frac{3}{14}[/tex]
Take the LCM
[tex]P = \frac{14 + 3}{42}[/tex]
[tex]P = \frac{17}{42}[/tex]
Also;
There are 3 C3 cards in the first deck out of a total of 12 cards, and there are 4 C5 cards in the second deck out of a total of 14 cards.
So, the probability that the player will choose a C3 card from the first deck or a C5 card from the second deck is:
