Answer: 4
Step-by-step explanation:
Find multiples of 12 and 16
4 is a common multiple
if you start from 1/4 and add 4 to the denominator and 1 to the numerator you get the following sequence:
1/4, 2/8, 3/12 and 4/16
Therefore the answer to the problem is 4

Step-by-step explanation:
A repair team is responsible for a stretch of oil pipeline 2 miles long. The distance (in miles) at which any fracture occurs can be represented by a uniformly distributed random variable, with probability density function f(x) = 0.5.
What is the probability that the next fracture will occur in the last half mile of the two mile interval?
Using the uniform distribution, it is found that there is a 0.25 = 25% probability that the next fracture will occur in the last half mile of the two mile interval.
The uniform distribution has two bounds, a and b.
The probability of finding a value above x is:
[tex]P(X > x) = \frac{b - x}{b - a}[/tex]
In this problem, the distribution is uniform over 2 miles, thus [tex]a = 0, b = 2[/tex].
The probability of a failure on the last half-mile is P(X > 1.5), thus:
[tex]P(X > 1.5) = \frac{2 - 1.5}{2 - 0} = 0.25[/tex]
0.25 = 25% probability that the next fracture will occur in the last half mile of the two mile interval.

In the playing card deck below what is the chance of pulling 4 face cards without replacing the cards in between pulls? Answer in decimal form rounded to the 6th digit after the
decimal
Answer:
0.13000
there is 52 cards in a deck so you take 52 and divide it by 4 since there is only 4 face cards you then get 13 and turn it into 0.13 then round to the 6th digit or millionth after the decimal so you would get 0.130000

Answer:
6(b)(b)(2b^2 +3)
Step-by-step explanation:
The greatest common factor is 6b^2. Factored fully, that is 6·b·b. The terms left after that is factored out are (2b^2 +3). These have no further common factors, or any factors in real numbers or integers.
The full factoring is ...

Express 960% as a mixed number
Answer:
9 3/5
Step-by-step explanation:
When we see a percentage, we know that the base is 100. In other words, 960% is equal to 960/100
With this, its just a matter of transforming the improper fraction to a mixed number.
100 fits 9 times in 960 so there will be 9 wholes
the remaining 60/100 can be simplified to 3/5 through this process:
60/100 = 6/10 = 3/5
Answer:
9 3/5
Step-by-step explanation:
Step 1: Write down the percent divided by 100 like this:
960% = 960/100
Step 2: Multiply both top and bottom by 10 for every number after the decimal point:
As 960 is an integer, we don't have numbers after the decimal point. So, we just go to step 3.
Step 3: Simplify (or reduce) the above fraction by dividing both numerator and denominator by the GCD (Greatest Common Divisor) between them. In this case, GCD(960,100) = 20. So,
(960÷20)/(100÷20) = 48/5 when reduced to the simplest form.
As the numerator is greater than the denominator, we have an IMPROPER fraction, so we can also express it as a MIXED NUMBER, thus 960/100 is also equal to 9 3/5 when expressed as a mixed number.

Suppose you deposit $200 in a savings account that earns 4% per year. Find the simple interest earned in 2 years. Then find the total of principal plus interest.
9514 1404 393
Answer:
interest: $16account total: $216Step-by-step explanation:
The amount of interest is given by the simple interest formula:
I = Prt . . . . where P is the amount earning interest, r is the annual rate, t is the number of years
I = $200·0.04·2 = $16.00
The simple interest earned in 2 years is $16.00.
__
The total of principal and interest is found by adding those values:
$200.00 +16.00 = $216.00
The total amount is $216.00.

Mixed numbers 204/5=
Answer:
Step 1 - Find Whole Number
Calculate out how many times the denominator goes into the numerator. To do that, divide 204 by 5 and keep only what is to the left of the decimal point:
204 / 5 = 40.8000 = 40
Step 2 - Find New Numerator
Multiply the answer from Step 1 by the denominator and deduct that from the original numerator.
204 - (5 x 40) = 4
Step 3 - Get Solution
Keep the original denominator and use the answers from Step 1 and Step 2 to get the answer. 204/5 as a mixed number is:
40

What is 204/6 as a Mixed Number?
Here is the next improper fraction on our list that we converted to a mixed number.
Terminology & Explanation
204 above the division line is called the numerator and 5 below the divison line is called the denominator.
We call the line that separates 204 and 5 the division line. It is also known as the fraction bar or vinculum.
204/5 is an improper fraction because the numerator is greater than the denominator.
A mixed number is an integer (whole number) and a proper fraction.

Answer:
-17-4y
Step-by-step explanation:
You just have to add the numbers:
-13+7-11=-17
=17-4y
The sum of the terms -13 + 7 and - 11 -4y is -4y - 17.
What is the sum?A summation, also known as a sum, is the outcome of adding two or more numbers or quantities. There are always an even number of terms in a summation. There could be only two terms, or there could be one hundred, a thousand, or a million.
Given:
-13 + 7 and - 11 -4y
Calculate the sum of the expression as shown below,
(-13 + 7) + (-11 - 4y)
-13 + 7 - 11 - 4y [In sum, the sign convention will be (+) + (-) = (-)]
Arrange the term as shown below,
-4y + 7 - 13 - 11
Apply the operation as shown below,
-4y + 7 - 24
-4y - 17
Thus, the sum will be -4y - 17.

Looking for the answer for the second one
Answer:
3 for the left one, and 5 on the right one.
Step-by-step explanation:
The scale factor is 2 because they are scaled from each other, meaning they have proportional side lengths. (The angles are also the same <hint for the next question>)
If the top side is 2.5, and the bottom is 5, then you divide to find the scaled factor since they correlate to each other.
If the side lengths on A is multiplied by 2, you can do that to the missing sides to find the answers.

Step-by-step explanation:
A tugboat goes 72 miles upstream in 9 hours. The return trip downstream takes 4 hours. Find the speed of the tugboat without a current and find the speed of the current.
Step-by-step explanation:
72÷9= 8, so the boat was only doing 8mph going upstream (against the current) the return trip downstream only took 4 hours. 72÷18=4 meaning the boat was traveling at 18mph downstream (no current) there is a 10mph difference between upstream and downstream therefore the current had to be running at 10 mph. so the speed of the tug boat is 8mph without a current and the current is running at 10mph.
