Answer:
-25677 = -3^4×317^1
Step-by-step explanation:
Factor the following integer:
-25677
Hint: | Show that 25677 is divisible by 9.
The sum of the digits of 25677 is 2 + 5 + 6 + 7 + 7 = 27, which is divisible by 9. This means 25677 is too
25677 = 9×2853:
-25677 = -9×2853
Hint: | Express 9 as a square.
9 = 3^2:
-25677 = -3^2×2853
Hint: | Show that 2853 is divisible by 9.
The sum of the digits of 2853 is 2 + 8 + 5 + 3 = 18, which is divisible by 9. This means 2853 is too
2853 = 9×317:
-25677 = -3^2×9×317
Hint: | Express 9 as a square.
9 = 3^2:
-25677 = -3^2×3^2×317
Hint: | 3 has no proper divisors.
3 is prime:
-25677 = -3^2×3^2×317
Hint: | Find a divisor of 317 by testing the integers between 2 and sqrt(317)≈17.8 for divisibility.
Because 317 is odd, only test odd numbers for divisibility
317 is not divisible by 3, 5, 7, 9, 11, 13, 15 or 17
Since 317 is not divisible by any integer up to 17, it is prime:
-25677 = -3^2×3^2×317
Hint: | Express -25677 as a product of prime powers.
There are 4 copies of 3 and 1 copy of 317 in the product:
Answer: -25677 = -3^4×317^1
Mr. Drew wants to build a square sandbox with an area of 225 square feet.
What is the total length of wood Mr. Drew needs to make the sides of the sandbox?
Answers
The length of the sandbox will be 15 feet.
What is the area of the square?The space occupied by any two-dimensional figure in a plane is called the area. The space occupied by the square in a two-dimensional plane is called the area of the square.
Given that Mr. Drew wants to build a square sandbox with an area of 225 square feet.
The length will be calculated by using the area formula for square.
Area of square = Length x width
Since the length and width of the square are the same. Then the area of the square can be written as:-
Area of square = ( Length )²
225 = ( Length )²
( Length ) = √225
( Length ) = 15 feet
Therefore, the length of the sandbox will be 15 feet.

Answers
Answer:
First, we need to list all the possible selections and the number of options that each selection has:
Style of home: 5 options.
Style of garage: 6 options.
Style of decks: 5 options.
Style of carpeting: 6 options.
The number of different combinations of possible homes is equal to the product between the number of options for each selection.
This is:
C = 5*6*5*6 = 900

A randomly selected participant from the study died during the five-year period. Calculate the probability that the participant was a heavy smoker. g
Answers
Answer: 0.421
Step-by-step explanation:
Heavy smoker = 20%
Light smoker = 30%
Non smokers = 50%
We can assume that the probability that a non-smoker is going to die in the next 5 years be y.
Since light smokers were twice as likely as nonsmokers to die during the five-year study, the probability will be:
= 2 × y = 2y
Probability for the Heavy smokers will be:= 2 × 2y = 4y
The expected number of people that will die for each in the next 5 years will be:
Non smoker:
= 50% × y
= 0.5 × y
= 0.5y
Light smoker:
= 30% × 2y
= 0.3 × 2y.
= 0.6y
Heavy smoker:
= 20% × 4y.
= 0.2 × 4y
= 0.8y
Total = 0.5y + 0.6y + 0.8y = 1.9y
The probability that the participant was a heavy smoker will be:
= 0.8y/1.9y
= 0.421
A bicycle manufacturing plant is producing the first few frames for their new electric bicycle design. The first batch of 60 frames has some issues: 1/3 of the frames had a weak junction where top tube meets the seat tube. After some fine tuning, a second batch of 120 frames is made, of which 1/4 are bad, still having the weak junction. Finally, another bug is fixed and a third batch of 180 frames is made and only 1/5 of these are bad. Unfortunately, due to a clerical error, all 360 frames were combined, unlabeled, into the same shipping bin. You have access to a quick test that checks if a bike frame is defective, which is correct with probability 9/10. That is, if the bike frame is defective, the test will say it is defective with probability 9/10. If the bike frame is not defective, the test will say it is defective with probability 1/10.
A) Determine the probability that the test returns "defective," P[D].B) Determine the probability that, given the test returns "not defective," the bike frame is not bad P[Bc |Dc].
Answers
Answer:
a) 131/450
b) 1233/1276
Step-by-step explanation:
P(bad) = P(1st batch)*P(bad 1st batch ) + P(2nd batch )*P(bad 2nd batch) + P(3rd batch )*P(bad 3rd batch)
p(bad) =(60/360)*(1/3) + (120/360)*(1/4 ) + (180/360)*(1/5)
= 43/180
And that of P(good )
= 1 - 43/180
= 137/180
a)
P(defective) = P(bad)*P(defective /bad) + P(good)*P(defective /good)
= (43/180)*(9/10) + (137/180)*(1/10)
= 131/450
b)
P(Bc I Dc ) = P(good)*P(not defective |good) / P(not defective)
= (137/180)*(1 - 1/10) / (1 - 131/450)
= 1233/1276

From 1960 to 1980, the consumer price index (CPI) increased from 29.6 to

increased at the same rate as the CPI from 1960 to 1980, by approximately
how much did the price of a pound of grapes increase from 1960 to 1980?
A. $0.82
B. $0.25
C. $0.39
D. $0.30
Answers
0.14 * 178/100 = $0.249 / $0.25 hence answer is B
The price of pound of grapes increased from 1960 to 1980 is $0.25.
What is a consumer price index?The Consumer price index (CPI) may be a measure of the typical change overtime within the prices paid by urban consumers for a market basket of goods and services.The CPI is one amongst the foremost popular measures of inflation and deflation. The CPI report uses a special survey methodology, prices sample and index weights than the producer index number (PPI), which measures change within the prices received by producers of products and services.Given:
CPI in 1960 = 29.6
CPI in 1980 = 82.4
Price of pound of grapes in 1960 = $0.14
We have to find the increase in the price of pound of grapes from 1960 to 1980.
Now, the rate of increase in the CPI from 1960 to 1980 is given by:
⇒ Rate = (CPI in 1980) / (CPI in 1960)
⇒ Rate = 82.4/29.6
⇒ Rate = 2.78
Now, the price of pound of grapes in 1980 will be calculated as:
⇒ Price of pound of grapes in 1980 = (rate of increase in the CPI from 1960 to 1980) × (Price of pound of grapes in 1960)
⇒ Price of pound of grapes in 1980 = 2.78 × $0.14
⇒ Price of pound of grapes in 1980 = $0.389
Increase in the price of pound of grapes from 1960 to 1980 will be calculated as:
⇒ Increase in the price = (Price of pound of grapes in 1980) - (Price of pound of grapes in 1960)
⇒ Increase in the price = $0.389 - $0.14
⇒ Increase in the price = $0.249
⇒ Increase in the price ≈ $0.25
Therefore, the approximate increase in the price of pound of grapes from 1960 to 1980 is $0.25.
Hence, Option (B) is correct.

What number should be at pyramid

When you see pyramids like these, they usually tell you to add/multiply the two numbers to get a third number that goes on top. Here, we can see 3 and 4 on the bottom left hand corner. The third number on top of both 3 and 4 is 7. 3 + 4 = 7. Let's check 4 and 5, the middle two numbers. 4 + 5 = 9, and that number is on top of 4 and 5. Therefore, we can confirm that this is an addition pyramid.

Owning a small and successful business isn't easy! There is a monthly cost of shipping supplies and
products of $2000. There is also a monthly cost of $1600 for each employee you hire. If you hire x
employees for the year, what is the total cost, C, in dollars, to keep your business running?
Answers
Answer:
[tex]C(x)=24,000+19,200x[/tex]
Step-by-step explanation:
Mathematical Modeling
To model a real-life situation, a mathematical model can be constructed in such a way it accurately represents the variables measured in the system.
This problem requires to build a model for the yearly cost of a small and successful business.
The first data is the fixed monthly cost or the money the owner must pay regardless of the number of employees he hires. This cost includes shipping supplies and products for $2,000. To operate for a full year, the fixed cost is 12*$2,000=$24,000.
The other component of the cost function is the variable cost of x employees. Given each employee costs $1,600 each month, having x employees cost 1,600x each month. For a full year, the variable cost will be
12*1,600x=19,200x.
We finally form the total cost function:
[tex]\boxed{C(x)=24,000+19,200x}[/tex]
What is g^-1(x)? What is the domain of g^-1(x)?
Answers
Answer:
g⁻¹(x) = 1/x - 4
(-∞, 0)∪(0, ∞)
Step-by-step explanation:
To find g⁻¹(x), switch the places of x and y. Rearrange the equation so that it is equal to y.
g(x) = 1/(x + 4)
x = 1/(y + 4)
x(y + 4) = (1/(y + 4))(y + 4)
x(y + 4) = 1
(x(y + 4))/x = 1/x
y + 4 = 1/x
y + 4 - 4 = 1/x - 4
y = 1/x - 4
g⁻¹(x) = 1/x - 4
For the domain, you need to look at where x is located in the equation. For this equation, x is in the denominator by itself. A fraction cannot have a denominator of 0. This means that x cannot be equal to 0. The domain is:
(-∞, 0)∪(0, ∞)
