Subtraction:
Subtraction represents the operation of removing objects from a collection. The minus sign signifies subtraction −. For example, there are nine oranges arranged as a stack (as shown in the above figure), out of which four oranges are transferred to a basket, then there will be 9 – 4 oranges left in the stack, i.e. five oranges. Therefore, the difference between 9 and 4 is 5, i.e., 9 − 4 = 5. Subtraction is not only applied to natural numbers but also can be incorporated for different types of numbers.
The letter "-" stands for subtraction. Minuend, subtrahend, and difference are the three numerical components that make up the subtraction operation. A minuend is the first number in a subtraction process and is the number from which we subtract another integer in a subtraction phrase.

Dilation:
Dilation refers the ratio of the given line to line by the scale factor.
Given
In the coordinate plane, line p has slope 8 and y-intercept (0, 5). Line r is the result of dilating line p by a factor of 3 with center (0, 3).
Here we need to find the the slope and y-intercept of line r.
Here we know that scale factor is 3.
Let us consider the slope of the line r will not change and the intercept is the addition of their ordinate will be.
So, it can be written as,
=> Intercept = 5 + 3

Tickets that cost $125 dollars each
Answers
Well the domain is the number of tickets and the range is the cost for those tickets.
So x = 1 when y = 125 (1 ticket is 125 dollars). Here is a reasonable domain and range comparision:
x = 1 , y = 125
x = 2, y = 250
x = 3, y = 375
x = 4, y = 500

The lower limit of the domain is 0 because you cannot have less than 0 tickets.

show that, if the wait() and signal() semaphore operations are not executed atomically, then mutual exclusion may be violated.
Answers
If the wait() and signal() semaphore operations are not executed atomically, then mutual exclusion may be violated as a wait operation atomically decrements the value associated with a semaphore.
Semaphores refers to integer variables utilized to solve the critical section problem by using two atomic operations, wait and signal that are used for process synchronization. The wait operation decreases the value of its argument S, if it is positive and if S is negative zero or negative, then no operation occurs. The signal operation increases the value of its argument S. Operation wait() and signal() must be completely atomic or else it violates the mutual exclusion. Mutual exclusion refers to the property of process synchronization which asserts that “no two processes can exist in the critical section at any given point of time”.

For these x's and y's, we can notice that y is always equal to 9 times the value of x. 0 equals 9 * 0, 9 equals 9 * 1, 18 equals 9 * 2, 27 equals 9 * 3, and 36 equals 9 * 4.

A 3 gallon bucket of paint costs $116.64. What is the price per cup?
Answers
Answer:
Step-by-step explanation:
You can use proportions to solve this.
You are paying $116.64 for 3 gallons of paint, so you could write this as:
\frac{116.64}{3}
Since the question is asking for price PER CUP, you want to convert 3 gallons to cups. 3 gallons = 48 cups. So now you can rewrite this as:
\frac{116.64}{48 cups}
In order to find the cost per cup, you can set up a proportion that solves for the price, x
\frac{116.64}{48 cups} = \frac{x}{1 cup}
Solve for x by cross multiplying:
48x = 116.64
x = $2.43
It costs $2.43 per cup of paint

Answers
In the given situation, the work done by gravity is zero as any work done during a downward part of the motion as undone during the upward parts.
Work refers to the measurement of energy transfer that happens when an object is moved over a distance by an external force which is applied in the direction of the displacement. Hence, the work done is given by the multiplication of force and displacement in the direction of force i.e., W = F x d. As in the given case, the displacement d = 0 as the particle returns to the same point. The work done by gravity would measure the displacement along the y-axis and as the total displacement is zero, hence, work done will be zero.

dinner cost?
Answers
The each type of dinner cost is ribeye steak dinner cost is $20.05 and grilled salmon dinner cost is $16.74 by using the equation.
Given that,
On one particular day, a waitress served 12 grilled salmon dinners and 19 ribeye steak dinners for a total of $581.52. She made $581.59 on another day by selling 24 ribeye steak dinners and 6 grilled salmon entrees.
We have to find what was the price of each kind of dinner.
So,
We take R as a ribeye steak dinner and S as grilled salmon dinners.
We get,
19R+12S=$581.52 ---> equation(1).
24R+6S=$581.59 ----> equation(2).
Now Take the equation (2)
24R+6S=$581.59
6S=$581.59-24R
Multiply 2 on both sides of equation.
12S=$1163.18-48R
Now take the equation(1)
19R+12S=$581.52
Take the 12S as 12S=$1163.18-48R
19R+$1163.18-48R=$581.52
-29R=$581.52-$1163.18
-29R=-581.66
29R=581.66
R=581.66/29
R= $20.05
Now substitute R in 12S=$1163.18-48R
We get,
12S=$1163.18-48($20.05)
12S=$1163.18-962.4
12S=200.78
S=200.78/12
S=$16.74

Answers
The confidence interval at a 90% is 29.533 ≤ μ ≤ 40.467
Given that
mean = 35
standard deviation = 15
We compute the confidence interval as follows:
μ =¯ˣ± ME
Where:
μ = is the population mean,¯x = 35 is the sample mean and,ME = is the margin of error.To calculate the margin of error, we will use the t-distribution since the sample is very small n<30. Thus, our margin of error will be calculated as:
ME = t ×[tex]\frac{s}{\sqrt{n} }[/tex]
Where:
t = is the t-score at the 90% confidence level
degree of freedom df = 24 -1 =23
s = 15 is the standard deviation and,
n =24 is the sample size.
From the t-distribution tables, we will read the values of t at a critical value [tex]\alpha[/tex] = 0.10, and the degree of freedom is 23. This will give t= 1.714.
Thus, the margin of error is:
ME = 1.714 ×[tex]\frac{15}{\sqrt{23} }[/tex]
ME = 1.714 ×3.19
ME = 5.467
the confidence interval for the population mean is equal to:
μ = 35 ± 5.467

The average cost to a 50-year-old male for a $100,000 term life policy is $14. 34 per month. The same policy would cost a 70-year-old male $79. 79 per month.
A 70-year-average old's monthly expense (MAC) is $79.79
A 50-year-average old's monthly expense (MAC) is $14.34
MAC → Monthly Average Cost
To get how much more will the 70-year-old pay for a 20-year term;
We will multiply the monthly value by the yearly and solve the given data,
The extra amount paid = (MAC of 70 years old * 12 - MAC of 50 years old * 12) * 20 years term.
= ($79.79 * 12 - $14.34 * 12) * 20

Answers
with 100 flips, the outcome is very likely to be 45 heads or even less.
just because you have a 50% chance of getting heads, does not necessarily mean that you will get heads at exactly 50%.
100 coin flips will not always produce a 50-50 outcome of heads or tails. This is due to the fact that random events, while predictable in the long run, are not 100% predictable in small cases. For example, if we flipped a fair coin a quadrillion times, the variability in the outcomes caused by the coin's randomness would amount to a fractional value so small that calculators might even round the percentage of heads to 50%. However, with 100 flips, the outcome is very likely to be 45 heads or even less.
