Half of 72 is 36. If you divided 36 by 4, you would get 9. So, s = 9 and means that it takes 9 seconds for the rock to be sunk half way.

Which bottle of water costs more per ounce: a 12
ounce bottle for $1.25 or a 16 ounce bottle for
$1.50?
I really need help with this!
Answer:
the second bottle
Step-by-step explanation:
To get the amount it costs per ounce, divide the amount of money by the number of ounces.
A water bottle that costs $1.25 for 12 ounces costs roughly 10 cents per ounce. A water bottle that costs about 9 cents per ounce.
therefore, the 16 ounce bottle is cheaper per ounce

Examine the following code:

while ( count <= 6 )
{
System.out.print( count + " " );
count = count + 3;
}
System.out.println( );
What does this code print on the monitor?

b. 0 1 2 3 4 5 6
c. 0 3 6
d. 0 1 2 3 4 5
e. 0 3
Answer:
the answer is c.036
Step-by-step explanation:
it can't be a, b or d because count is being increased by 3 and not 1. And it can't be e because the loop is <= and not < so when the count is 6 it is still in the loop. So it will show the 6 as well

Answer:
(x, y) = (6, 8) using linear combination
Step-by-step explanation:
The coefficients of the x-terms are opposites of each other (2 and -2), so the x-terms can be eliminated using a linear combination of the equations.
Adding the two equations together gives ...
(2x -y) +(-2x +3y) = (4) +(12)
2y = 16 . . . . . . . . simplify
y = 8 . . . . . . . divide by 2
Substituting for y in the first equation gives ...
2x -8 = 4
x -4 = 2 . . . . . divide by 2
x = 6 . . . . . . . add 4
The solution is (x, y) = (6, 8).

Given that a randomly selected person uses at least two facilities, what is the probability they use all the facilities?
Of 103 people that are considered to use two facilities, only 14 use all three. In this case, we must make a percentage of this information.
This is roughly 14.5%, meaning there is only a 14.5% chance someone will use all three facilities if they are known to use two.
The probability that a randomly selected person uses at least two facilities is 103/135 and the probability that the selected people uses all the three facilities is 14/103.

Take Action: Work on the Weekends.
Answer:
If your due dates are at least by the end of the week, I recommend doing straight work for 30 minutes, then rewarding yourself. Repeat this for as long as you want but don't do so much that you weren't able to do anything socially for the whole day. If your due dates are already passed or if they are coming up really soon, I recommend putting on whatever music you like to listen to, but nothing to upbeat. Put on some calm music with a rain sound effects video in the background, and just keep working until you kind of dose off from reality and just get in the zone. A long answer, but it really helps.
Forgot to mention; if you ever get stressed out, either do something else to calm down, or use that stress to your advantage and do a ton of work because of it.

Step-by-step explanation:
// Solve equation [2] for the variable y
[2] y = x - 2
// Plug this in for variable y in equation [1]
[1] (x -2) + x = 4
[1] 2x = 6
// Solve equation [1] for the variable x
[1] 2x = 6
[1] x = 3
// By now we know this much :
y = x-2
x = 3

In Vietnam, the probability of rain is 70%. Find the
probability of it raining at most 2 days in a week.
a) .9712
b) 0.0250
c) .0287
d) .2988
Answer: the answer is C which is .0287
The probability of it raining at most 2 days in a week is approximately 0.0192 or 1.92%. The closest option to this result is:
b) 0.0250
To find the probability of it raining at most 2 days in a week, we need to calculate the probability of it raining 0, 1, or 2 days in a week and then add those probabilities together.
Let's use the binomial probability formula for this calculation:
The probability of getting exactly "k" successes in "n" trials, each with a probability "p" of success, is given by:
P(X = k) = C(n, k) * p^k * (1 - p)^(n - k)
where:
C(n, k) is the binomial coefficient, equal to n! / (k! * (n - k)!)
p is the probability of success (rain in this case)
n is the number of trials (number of days in a week)
In our case, the number of trials (n) is 7 days in a week, and the probability of rain (p) is 0.70.
Now, let's calculate the probabilities for k = 0, 1, and 2:
Probability of raining 0 days in a week:
P(X = 0) = C(7, 0) * 0.70^0 * (1 - 0.70)^(7 - 0)
Probability of raining 1 day in a week:
P(X = 1) = C(7, 1) * 0.70^1 * (1 - 0.70)^(7 - 1)
Probability of raining 2 days in a week:
P(X = 2) = C(7, 2) * 0.70^2 * (1 - 0.70)^(7 - 2)
Now, add these probabilities together to get the probability of it raining at most 2 days in a week:
P(X ≤ 2) = P(X = 0) + P(X = 1) + P(X = 2)
Calculate the values using the binomial coefficients:
C(7, 0) = 1
C(7, 1) = 7
C(7, 2) = 21
Now, calculate the probabilities:
P(X = 0) = 1 * 1 * 0.3^7 ≈ 0.0002187
P(X = 1) = 7 * 0.7^1 * 0.3^6 ≈ 0.002775
P(X = 2) = 21 * 0.7^2 * 0.3^5 ≈ 0.016215
Finally, add these probabilities together:
P(X ≤ 2) ≈ 0.0002187 + 0.002775 + 0.016215 ≈ 0.0192087
Therefore, the probability of it raining at most 2 days in a week is approximately 0.0192 or 1.92%. The closest option to this result is:
b) 0.0250
So, the correct answer is (b) 0.0250.
