A carpenter has 2 pipes which are 60 dm and 72 dm long respectively. he cuts them into equal lengths. what is the greatest possible length of each pipe?
Answers
Using greatest common factor (GCF), the greatest possible length of each pipe is 12 dm.
The greatest common factor (GCF) of a set of numbers is defined as the largest common positive integer that divides each number into equal parts with zero remainder.
If a carpenter has 2 pipes which are 60 dm and 72 dm long, respectively and he cuts them into equal lengths, then the greatest possible length of each pipe is the GCF of 60 and 72.
60 : 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, 60
72 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 24, 36, 72
common factors : 1, 2, 3, 4, 6, 12
GCF = 12
Hence, he should cut the two pipes into 12 dm long.

two cards are drawn without replacement from a standard deck of 52 playing cards. what is the probability of choosing a diamond and then, without replacement, a black card? express your answer as a fraction or a decimal number rounded to four decimal places.
Answers
Answer:
13/102
Step-by-step explanation:
We start with 52 playing cards. Of these 52 cards, 13 are diamonds, So the probability of a diamond is 13/52, or 1/4. There are now 51 cards left. Since the diamond is a red card, there are 26 black cards. So the probability of a black card is 26/51. Multiplying 1/4 and 26/51, and then simplifying, we have 13/102.
In the equation
2H₂ + 102 →→ 2H₂O
if you change the 2H₂ to 3H2 molecules and balance the equation, which statement is correct?
Answers
If you change the 2H₂ to 3H₂ molecules and balance the equation the equation will produce three molecules of water.
The provided chemical equation is,
2H₂ + O₂ → 2H₂O.
Changing 2H₂ with 3H₂
The chemical equation becomes,
3H₂ + O₂ → 2H₂O.
By doing this, the equation has become completely imbalanced,
So first we will balance it,
3H₂ +3/2O₂ → 3H₂O
Now, there will be 3 molecules of water formed.
As we observe the reaction more closely, we can see that the number of atoms of all the elements are equal on both the sides of the reaction.

< A and < B are supplementary angles. If m m < B= (2x+30), then find the measure of < A.
Answers
Answer:
m<A = 50°
Step-by-step explanation:
supplementary angles add up to 180°
m<B = 2x + 30
we don't know m<A, so we'll say the value of it is x
2x + 30 + x = 180°
3x + 30 = 180
3x = 150
x = 50
plug this value back in for x
m<B = 2(50) + 30 = 130
m<B = 130°
m<A = x = 50
m<A = 50°
to prove these are supplementary angles, 130 + 50 = 180

one out of every 9 light bulbs is defective. What constant of proportionality relates defective bulbs to total bulbs?
Answers
the constant of proportionality that relates defective bulbs to total bulbs is 1 / 9.
We are given that 1 bulb out of every 9 bulbs is defective.
So, this means that if there is a total of 9 bulbs, then 1 bulb in it will be defective.
Let us assume:
Total bulbs = 9
So, this implies that:
Defective bulbs = 1
Constant of proportionality = Defective bulbs / Total bulbs.
Substituting the values in this, we get that:
Constant of proportionality = 1 / 9
Therefore, we get that, the constant of proportionality that relates defective bulbs to total bulbs is 1 / 9.

Keep a record of what polynomials you tried, and the results. When you think you have an answer to your question, explain your reasoning using equations, graphs, visuals, calculations, words, or in any way that will help others understand your reasons.
Answers
Polynomials are closed under the multiplication operation, meaning that the result of the multiplication between two polynomials will always be a polynomial.
How to multiply polynomials?To multiply polynomials, we first apply the distributive property, multiplying all terms, then we combine the like terms, that is, adding all the terms that have the same exponents.
Since all the factors of the multiplications will be of polynomial terms, the results of the multiplication will be polynomial, and so will the like terms combined, hence polynomials are closed under the multiplication operation.
One example of multiplication of polynomials is given as follows:

2. we want to estimate the mean of a population. a random sample of subjects is selected and the sample mean is computed. what is the probability that the sample mean is within 3 units of the true mean if the standard error is 1.8?
Answers
Given,
Sample mean = ±3 of true mean
Standard error = 1.8
Therefore,
Required probability of sample mean being within 3 units of the true mean is,
P ( sample mean - 3 < mean < sample mean + 3 )
= P [( sample mean - 3 ) - mean / 1.8 ] < mean - sample mean / 1.8 < [ ( sample mean + 3 ) - mean / 1.8 ]
= P ( - 1.67 < ∉ < 1.67)
= P (∉ < 1.67) - P( ∉ < 1.67)
= 0.952 - 0.047
= 0.905
Hence, the probability that the sample mean is within 3 units of the true mean if the standard error is 1.8 is 0.905.

8 units is the radius of the circle with a circumference of 16π.
What is the radius of the given circle?A circle is simply a closed 2-dimensional curved shape with no corners or edges.

C = 2 × π × r
Where r is radius and π is constant pi ( π = 3.14 )
Given the data in the question;
Circumference C = 16πRadius r = ?To find the radius of the circle, plug the given value into the circumference formula and solve for r.
C = 2 × π × r

Answers
The answers to both the subparts with the help of probability are:
(A) The $15 wager's expected value is a loss of $3.16.(B) Since the bet on a single number has a higher expected value, it is better.What is probability?Simply put, the probability is the likelihood that something will occur. When we don't know how an event will turn out, we can discuss the likelihood or likelihood of various outcomes. Statistics is the study of events that follow a probability distribution. The probability is equal to the variety of possible outcomes: the total number of outcomes that could occur. For instance, there is only one way to get a head and there are a total of two possible outcomes, so the probability of flipping a coin and getting heads is 1 in 2 (a head or tail).So, Item A:
The probability of earning $75 is 5/38.The likelihood of losing $15 is 33/38.The expected value is the total of each result times the associated probability, so:
[tex]E(X)=75 \frac{5}{38}-15 \frac{33}{38}=\frac{75(5)-15(33)}{38}=-3.16[/tex]The $15 wager should have a value of -3.16 dollars.
Item B:
The wager on a single number has an expected value of $-0.79 (or -$0.79).The best wager is a bet on a single number because it is higher than the expected value of the bet on multiple numbers.Therefore, the answers to both the subparts with the help of probability are:

Ling painted a picture of a local historic landmark for her history project. First, she painted a statue using a mix of black and white paint. Then, she painted a stone building using double the amount of black paint and double the amount of white paint. Which structure was a darker shade of gray?
Answers
Answer: Neither They were the same shade of Grey.
Step-by-step explanation:
it’s the right answer trust me
Color would be the same for both statue and stone buildings.
Let's, consider paint black as = x
and paint white as = y
If both the paints are mixed then paint z which is grey is formed.
Represented as,
x(black) + y(white) = z(grey)
Whereas, for the stone building double the amount of black and white colors are being used,
2x + 2y = 2z, coating of grey color would be also double.
Canceling 2 from both sides,
x + y = z
x(black) + y(white) = z(grey)
Therefore color would be the same for both statue and stone buildings.
