Answer: 1/25
Step-by-step explanation:
Number of balls = 10
Number of purple balls = 2
Since it's probability with replacement,
Probability of picking a purple ball the first time = 2/10 = 1/5
Probability of picking a purple ball the second time = 2/10 = 1/5
Therefore, the probability of picking a purple ball both times will be:
= 1/5 × 1/5
= 1/25
Which pair of equations below is a result of constructing the altitude, h, in traingle ABC?
Answer:
sinA = h/c; sinC = h/a
Step-by-step explanation:
Which pair of equations below is a result of constructing the altitude, h, in Triangle ABC?
sinA= h/c
sinC= h/a
sinA= h/c
sinB= b/c
sinA= b/c
sinC= b/a
Solution:
A triangle is a polygon with three sides and three angles. There are different types of triangles such as right angled, acute, obtuse and isosceles triangle.
In right angle triangle, one angle is 90°. From Pythagoras theorem, the square of the longest side (hypotenuse) is equal to the sum of the square of the two sides.
In right triangle, trigonometric identities are used to show the relationship between the sides of a triangle and the angles.
sinθ = opposite / hypotenuse, cosθ = adjacent / hypotenuse, tanθ = opposite / adjacent
Therefore in triangle ABC:
sinA = h/c; sinC = h/a

-(23/47)
Which of the following is equivalent to the given number?
ASAP
Given:
The number is:
[tex]-(\dfrac{23}{47})[/tex]
To find:
The number that is equivalent to the given number.
Solution:
In option A,
[tex]-(-\dfrac{23}{47})=\dfrac{23}{47}[/tex] [tex][\because (-)(-)=(+)][/tex]
In option B,
[tex]\dfrac{23}{-47}=-\dfrac{23}{47}[/tex]
In option C,
[tex]\dfrac{-23}{-47}=\dfrac{23}{47}[/tex]
In option D, we have
[tex]\dfrac{23}{47}[/tex]
The numbers in options A, C and D are equivalent to [tex]\dfrac{23}{47}[/tex]. So, options A, C and D are incorrect.
The numbers in options B is equivalent to [tex]-(\dfrac{23}{47})[/tex]. So, option B is correct.
Therefore, the correct option is B.

If the percentage is 20%, the down payment is $177,100
If the percentage is 10%, the down payment is $88,550
Step-by-step explanation:
This is a terrible question, in my opinion, unless they gave more information at the top of the page. A down payment on a house can be anywhere from 3.5% to 20%
Let's go with the 20%
885,500 x 0.20 = 177,100

Your baby brother has an ear infection. The doctor said there are probably 50,000 bacteria in his left ear. The penicillin the doctor prescribed will kill 7% of the bacteria every hour. About how long will it take for there to be less than 25,000 bacteria?
Answer:
Ok I'm not sure but (9 hours)
Step-by-step explanation:
50,000 divided by 25,000 = 7
7 plus 2 equals 9.
An artist receives royalties for all digital downloads of his music. For the first 10,000 downloads, the artist receives $10,000. He receives $12,500 for the next 10,000 downloads, $15,000 for the next 10,000 downloads and so on. How much money will he receive if his music is downloaded 500,000 times?
Answer:
Step-by-step explanation:
This is a linear relationship. We know this because as the number of songs increases by 10,000 the amount of money increases $2500. We can use that relationship in a proportion, which is a method used to solve problems involving directly proportional numbers.
If we arrange our information such that the dollars earned are on the top of the fraction and the number of songs that need to be downloaded to earn that amount of money is on the bottom of the fraction, here is what we have:
[tex]\frac{2500}{10,000}[/tex]. This means that the artist receives $2500 for every 10,000 downloads. Keeping in that pattern, we can find out how much money he will earn when 500,000 downloads are completed, assuming that the amount he earns per 10,000 songs doesn't change.
[tex]\frac{2500}{10000}=\frac{x}{500000}[/tex] and cross multiply to get
10,000x = 1250000000 and divide to get
x = 125,000
That is the amount that he will earn from 500,000 downloads.

The length of a rectangular prism is four times the width. The height of the prism is 160ft^3, what is the width of the prism? Round the the nearest tenth of a foot
Answer:
The width of the prisim is equal to 2.23 feet.
Step-by-step explanation:
let l is length and b is width.
Length, l = 4b
The volume of the prism is 160 ft³.
The height of the prism is 8 ft.
The formula for the volume of a prism is given by :
[tex]V=lbh\\\\160=4b\times b\times 8\\\\160=32b^2\\\\b^2=\dfrac{160}{32}\\\\b=\sqrt5\\\\b=2.23\ ft[/tex]
So, the width of the prisim is equal to 2.23 feet.

Answer:
Step-by-step explanation:
volume=15×5×5+8×4×5+8×4×5
=375+160+160
=695 m³
Answer:
695 m^3
Step-by-step explanation:
With this object, there are three rectangular prisms. The equation to find the volume of them is L*W*H.
So, with the small one in the front, the sides are 8, 4, and 5, so do:
8*4*5 ---> 160
Next, with long middle one, the sides are 5, 5, and 15, so do:
5*5*15 --->375
Then, with small one in the back, 8, 4, and 5 again, so do:
8*4*5 ---> 160
To finish it off, add them all together.
160 + 375 + 160 = 695 m^3

The solution to an inequality is x < 3.5. Which of the following statements and graphs are true? Select all that apply.
Answer:
any nuber less then 3.5 and 5th awnser
Step-by-step explanation:
x is less then 3.5 so any number less then 3.5
5th one is true too because you can go into negitves and tehre is are infanite negitives
Answer:
The following statements and graphs are true:
x < 3.5
Any number that is less than 3.5 is a solution.
There are an infinite number of solutions.
The statement "x ≤ 3.5" is not true because the original inequality states that x is strictly less than 3.5, not less than or equal to 3.5. The statement "Any number that is greater than 3.5 is a solution" is also not true for the same reason. Finally, 3.5 is not a solution to the inequality because the inequality is strict: it only includes values of x that are strictly less than 3.5.
________________________________________________________
What is the difference between strict and non-strict inequalities?The difference between strict and non-strict inequalities is that strict inequalities use "<" or ">" symbols, which exclude the boundary values, while non-strict inequalities use "≤" or "≥" symbols, which include the boundary values.
For example, the inequality x < 5 is a strict inequality, which means that x can be any number less than 5, but it cannot be 5 itself. On the other hand, the inequality x ≤ 5 is a non-strict inequality, which means that x can be any number less than or equal to 5.
Similarly, the inequality y > -3 is a strict inequality, which means that y can be any number greater than -3, but it cannot be -3 itself. The inequality y ≥ -3 is a non-strict inequality, which means that y can be any number greater than or equal to -3.
What are some real-life applications of inequalities, and how are they used in various fields of study?Inequalities are used in a variety of real-life applications, including:
Business and economics: Inequalities are used to represent constraints in optimization problems, such as maximizing profits subject to resource limitations.
Engineering and physics: Inequalities are used to represent physical constraints, such as maximum and minimum values for quantities like speed, acceleration, and force.
Health and social sciences: Inequalities are used to represent inequalities in health outcomes and access to healthcare, as well as social inequalities related to income, education, and other factors.
Computer science and optimization: Inequalities are used to represent constraints in optimization problems, such as scheduling, routing, and allocation of resources.
Probability and statistics: Inequalities are used to bound the probability of events and to represent relationships between random variables.
Inequalities are also used in various fields of mathematics, including algebra, geometry, and analysis. They are important tools for proving theorems and solving problems in these areas.
