The density of water is 1 g/mL, so for this problem, we would multiply 103.8 mL by 1 g/mL to get our answer of 103.8 grams.
The density of water is 1 gram per milliliter (1 g/mL). This means that for every milliliter of water, there is 1 gram. Therefore, to answer the question of how many grams of C12H24012 is needed to acquire the needed volume of water (103.8 mL), we need to multiply the volume of water by the density of water. To do this, we will use the equation: Mass (g) = Volume (mL) x Density (g/mL). For this problem, the equation would be: Mass (g) = 103.8 mL x 1 g/mL.Therefore, the answer to the question is 103.8 grams of C12H24012 is needed to acquire the needed volume of water.In conclusion, to figure out how many grams of C12H24012 is needed to acquire the needed volume of water, we need to multiply the volume of water (in mL) by the density of water (in g/mL). The density of water is 1 g/mL, so for this problem, we would multiply 103.8 mL by 1 g/mL to get our answer of 103.8 grams.

Microsoft Windows XP operating system is installed on 20% of the company's computers, Microsoft Windows 7 is installed on 85% of computers, and Linux operating system is installed on 10%. At the same time, Linux and Microsoft Windows 7 are installed on 6% of computers, Microsoft Windows XP and Linux on 4%, all three programs are installed on 2% of computers. How many percent of computers have the Microsoft operating system installed?
To find out how many percent of computers have the Microsoft operating system installed, we need to add up the percentage of computers that have Windows XP and Windows 7 installed.
First, let's find out how many percent of computers have both Windows 7 and Linux installed:
85% (Windows 7) - 6% (Windows 7 & Linux) = 79% (Windows 7 only)
Next, let's find out how many percent of computers have both Windows XP and Linux installed:
20% (Windows XP) - 4% (Windows XP & Linux) = 16% (Windows XP only)
Finally, let's add up the percentage of computers that have Windows XP and Windows 7 installed:
79% (Windows 7 only) + 16% (Windows XP only) = 95%
So, 95% of the company's computers have the Microsoft operating system installed.
Answer:
o calculate the percentage of computers with the Microsoft operating system installed, we need to find the total number of computers that have either Windows XP or Windows 7 installed.
Microsoft Windows XP operating system is installed on 20% of the company's computers, so 20% of the computers have Windows XP installed.
Microsoft Windows 7 is installed on 85% of computers, so 85% of the computers have Windows 7 installed.
Linux and Microsoft Windows 7 are installed on 6% of computers, so 6% of the computers have both Windows 7 and Linux installed.
Microsoft Windows XP and Linux on 4% of computers, so 4% of the computers have both Windows XP and Linux installed.
All three programs are installed on 2% of computers, so 2% of the computers have all three programs installed.
To avoid double-counting the computers that have both Windows 7 and Linux installed, we need to subtract 6% from the total number of computers with Windows 7 installed. The same applies to the computers that have both Windows XP and Linux installed, so we need to subtract 4% from the total number of computers with Windows XP installed.
The total number of computers with Windows XP or Windows 7 installed is 20% + (85% - 6%) + (20% - 4%) = 20% + 79% + 16% = 115%.
So, 115% of the company's computers have the Microsoft operating system installed.

Probability determines the likelihood of an event occurring: P(A) = f / N. Odds and probability are related but odds depend on the probability. You first need probability before determining the odds of an event occurring.
P(A) = f / N.
probability = 2%/100=0.0002
One of the areas of probability theory is the estimation of the chance of experiments occurring. Using a probability, we can calculate everything from the likelihood of getting heads or tails when flipping a coin to the likelihood of making a research error, for example. It is essential to appreciate the most basic definitions of this branch, such as the formula for computing probabilities in equiprobable sample spaces, the likelihood of two events joining together, the probability of the complementary event, etc., in order to properly understand it .Probability refers to potential. A random event's occurrence is the subject of this area of mathematics. Mathematics has incorporated probability to forecast the likelihood of various events.

An aeroplane flies 1400km in 1h 45mins.how far will it fly in 2h 30min at the same avarage speed?
Answer:
The aeroplane will fly 2000 km if travelling at the same average speed.
Step-by-step explanation:
To calculate the distance an aeroplane will fly in 2 h 30 min if it flies 1400 km in 1 h 45 mins, use the Speed Distance Time formula.
[tex]\boxed{\sf Speed=\dfrac{Distance}{Time}}[/tex]
There are 60 minutes in one hour. Therefore:
1 h 45 mins = 1.75 hours2 h 30 mins = 2.5 hoursTo calculate the speed of the aeroplane, divide the distance by the time it takes to travel that distance. Therefore, if an aeroplane flies 1400 km in 1.75 hours then its average speed is:
[tex]\sf Speed=\dfrac{1400\;km}{1.75\;h}=800\;km/h[/tex]
To determine the distance the aeroplane will travel in 2.5 hours, multiply the found speed of 800 km/h by the time:
[tex]\sf Distance=800\;km/h \times 2.5\;h=2000\;km[/tex]
Therefore, the aeroplane will fly 2000 km in 2 h 30 min if travelling at the same average speed.

what is the minimum value of y=x^2+36/5
Answer:
(36/5)
Step-by-step explanation:
y=x^2+36/5
Since x is squared, the result will always be a positive number, regardless of the actual value of x. Starting with a value of x of zero, the x^2 term will only grow as one moves away from 0. E.g., (-1)^2 = 1, (-2)^2 = 4, etc.
So the minium for this equation will occur when x = 0. It only gets larger from that point. The minimum is (36/5).

a force of 192 lb is required to hold a spring stretched 3 ft beyond its natural length. how much work w is done in stretching it from its natural length to 9 inches beyond its natural length?
The work required to stretch the spring from its natural length to a distance of 9 inches beyond its natural length is 2.25 lb-ft.
The problem involves calculating the work required to stretch a spring from its natural length to a distance of 9 inches beyond its natural length, given that a force of 192 lb is required to hold the spring stretched 3 ft beyond its natural length.
To solve the problem, we use the formula for the work done by a force that varies with distance, which is given by:
W = (1/2) k (x2^2 - x1^2)
where W is the work done, k is the spring constant, x1 is the initial distance, and x2 is the final distance.
In this case, the initial distance is the natural length of the spring, which is 0 ft, and the final distance is 9/12 ft. To find the spring constant, we use the fact that a force of 192 lb is required to hold the spring stretched 3 ft beyond its natural length, which gives us:
192 = k * 3
Solving for k, we get k = 64 lb/ft.
Substituting the values into the formula, we get:
W = (1/2) * 64 * (9/12)^2
Simplifying, we get:
W = 2.25 lb-ft
This calculation shows how the work done by a force that varies with distance can be calculated using the spring constant and the distances involved.

Two rotten in a row has the probability (4/15)*(3/14) = 2/35. I skipped a few steps so let me know if you need to see in more detail how I got to that result.
Answer: 2/35=====================================================
Part (b)
We want to calculate the probability exactly one of the two oranges selected is rotten.
There are two possible cases here:
Case 1) The first orange is rotten and the second is not rotten.Case 2) The first orange is not rotten and the second is rotten.Let's determine the probability for case 1.
4/15 was mentioned earlier in part (a) as the probability of a rotten orange. There are 15-4 = 11 non-rotten oranges and 15-1 = 14 remaining since we aren't replacing the first selection. That gives 11/14 as the probability the 2nd selection is fresh.
We get (4/15)*(11/14) = 22/105 as the probability for case 1 to happen.
Through similar calculations, the probability for case 2 is (11/15)*(4/14) = 22/105
Cases 1 and 2 are mutually exclusive. Both cannot happen simultaneously. There is no overlap. This fact allows us to add the results to get:
22/105 + 22/105 = 44/105
That fraction cannot be reduced.

Solve the equation for x (0 ≤ x ≤ 2π)
cos²x + sin x = 1
To solve the equation cos²x + sin x = 1, we can use the trigonometric identity cos²x = 1 - sin²x. By substituting this identity into the equation, we get:
1 - sin²x + sin x = 1
Combining like terms, we get:
1 - sin²x = 0
Solving for sin x, we get:
sin x = 1
However, the sine function has a range of [-1, 1], so the only solution in the interval [0, 2π] is sin x = 1, which corresponds to x = π/2. So the solution to the equation cos²x + sin x = 1 in the interval [0, 2π] is x = π/2.
