Aaron's mom had a long day at work. "I feel like I drank 3 gallons of coffee today!" she joked. If she really drank that much coffee, how many times would she have filled her 12-fluid-ounce mug?
The number of times that she has filled her 12-fluid-ounce will be 33.307.
What is conversion?Unit modification is the process of converting the measurement of a given amount between various units, often by multiplicative constants that alter the value of the calculated quantity without altering its impacts.
We know that in 1 gallon, there are 133.228 fluid ounces.
The amount of coffee in 3 gallons will be given as,
3 gallons = 3 x 133.228
3 gallons = 399.684 fluid ounces
The number of times that she has filled her 12-fluid-ounce will be given as,

a population has a mean of 120 and a standard deviation of 10. if a sample of size 25 is collected, how much distance on average is expected between the sample mean and the population mean?
When a sample of size 25 is taken from a population with a mean of 120 and a standard deviation of 10,The expected distance between the sample mean and the population mean is 2.5.
The mean of a population is the average value of all the data points, while the standard deviation is a measure of how spread out the data points are. When a sample of size 25 is taken from a population with a mean of 120 and a standard deviation of 10, the expected distance between the sample mean and the population mean is 2.5. This is because the standard deviation of the sample mean is equal to the population standard deviation divided by the square root of the sample size. In this case, the standard deviation of the sample mean would be 10/5 = 2, and the expected distance between the sample mean and the population mean would be 2 x 2.5 = 2.5.
Standard deviation of the sample mean = Population standard deviation / √ Sample size
= 10 / √25
= 10 / 5
= 2
Expected distance between the sample mean and the population mean = 2 x 2.5
= 2.5

The equation of the line n parallel to line m will be y = 3/2x - 9. The correct option is A.
What is an equation of the line?An equation of the line is defined as a linear equation having a degree of one. The equation of the line contains two variables x and y. And the third parameter is the slope of the line which represents the elevation of the line.
The general form of the equation of the line:-
y = mx + c
m = slope
c = y-intercept
Slope = ( y₂ - y₁ ) / ( x₂ - x₁ )
The equation of the lime m perpendicular to the line y = -2/3x + 6 will be,
y = 3/2x + c
The line n is parallel to n and passes through the point (4,-3),
y = 3/2x + c

|2х - бу = 1
х- y=1
Answer:
To solve this system, we need to find the values of x and y that make both equations true at the same time.
Let's start by solving the first equation for y:
|2х - бу = 1
2х - бу = 1
-2х + бу = -1
бу = 1 - 2х
y = (1 - 2х)/б
Now let's substitute this expression for y into the second equation:
x - (1 - 2х)/б = 1
x - 1 + 2х/б = 1
3х/б = 0
x = 0
Substituting this value for x back into the first equation, we get:
y = (1 - 2*0)/б = 1/б
So the solution to the system of equations is x = 0 and y = 1/б.

S: {−65, −39, 4, 39}
Answer:
t = 39
Step-by-step explanation:
t - 52 = - 13 ( isolate t by adding 52 to both sides )
t = - 13 + 52 = 39
the integer from the solution set S that makes the equation true is 39
Answer:

Find each of the missing sides and angles of the following triangle. Round to the nearest tenth if necessary. (one decimal) \large m\angle B= º a = b =
The right-angled triangle have angle B = 40°, side c = 20.9 and b = 13.4 approximately to the nearest tenth.
How to calculate for the missing angles and sides of the right-angled triangleWe shall use the trigonometric ratios of sine and cosine of the angle 50° to get the length of the sides and apply the rule of the sum of interior angles of a triangle to get the angle B.
sin50° = opposite/hypotenuse
sin50° = 16/c
c = 16/(sin50°) {by cross multiplication}
c = 20.9
cos50° = adjacent/hypotenuse
cos50° = b/20.9 {by cross multiplication}
b = 20.9 × cos50°
b = 13.4
The sum of interior angles of a triangle is equal to 180° so;
angle B = 180° - (90° + 50°)
angle B = 180° - 140°
angle B = 40°
Therefore, by application of trigonometric ratios sine and cosine, we have the sides of the right-angled triangle b = 13.4, c = 20.9, and the angle B = 40°.

What is the value of expression 10!/(4!7!)
Answer:
3
Step-by-step explanation:
The factorial of a number n is the product of all the positive integers from 1 to n. In other words, n! = 1 * 2 * 3 * ... * n. For example, the factorial of 5 is 5! = 1 * 2 * 3 * 4 * 5 = 120.
In this case, we are asked to find the value of the expression 10!/(4!7!). To do this, we first need to evaluate the factorials in the numerator and denominator of the expression. Since 10! = 1 * 2 * 3 * ... * 10, we have:
10! = 1 * 2 * 3 * 4 * 5 * 6 * 7 * 8 * 9 * 10 = 3628800
Similarly, since 4! = 1 * 2 * 3 * 4 and 7! = 1 * 2 * 3 * 4 * 5 * 6 * 7, we have:
4! = 1 * 2 * 3 * 4 = 24
7! = 1 * 2 * 3 * 4 * 5 * 6 * 7 = 5040
Now that we have evaluated the factorials in the expression, we can plug these values into the expression and evaluate it:
10!/(4!7!) = 3628800 / (24 * 5040) = 3628800 / 120960 = 3
Therefore, the value of the expression 10!/(4!7!) is 3.
Note: It is important to remember that the factorial of 0 is defined to be 1, so 0! = 1. This means that any expression involving 0! can be simplified by replacing 0! with 1. For example, the expression 10!/(4!7!0!) can be simplified as follows:
10!/(4!7!0!) = 10!/(4!7!1) = 10!/(4!7) = 10!/(24 * 7) = 10!/168 = 3628800/168 = 3
This is the same result we obtained above using the factorials of 10, 4, and 7.
The value of the given expression is 30.
What is an expression?An expression is a combination of terms that are combined by using mathematical operations such as subtraction, addition, multiplication, and division.

The area of mathematics known as probability deals with numerical representations of the likelihood that an event will occur or that a statement is true. An event's probability is a number between 0 and 1, where, roughly speaking, 0 denotes the event's impossibility and 1 denotes certainty.
A probability is a numerical representation of the likelihood or chance that a specific event will take place. Both proportions ranging from 0 to 1 and percentages ranging from 0% to 100% can be used to describe probabilities.
The given information is expressed as
Side effect no side effect total
Adult 7 43 50

Given the following sequence, find the 77th term.
-8, -4, 0, 4, 8, ...
Answer:
Step-by-step explanation:
The given sequence is an arithmetic sequence with a common difference of 4. The 77th term of the sequence is the 77th term of the arithmetic sequence, which is given by the formula:
a_n = a_1 + (n - 1) * d
where a_n is the nth term of the sequence, a_1 is the first term of the sequence, and d is the common difference. Substituting the values for a_1, n, and d into this formula, we get:
a_77 = -8 + (77 - 1) * 4
= -8 + 76 * 4
= -8 + 304
= 296
Therefore, the 77th term of the sequence is 296.
find two numbers whose difference is 88 and whose product is a minimum. (smaller number) (larger number)
Two two numbers whose difference is 88 and whose product is a minimum are -44 and 44.
How to solve?Let the numbers be x and y where x is larger value and y is smaller number.
According to ques,
x - y =88
and we need to make product of numbers i.e 'xy' minimum.
So we can take x = 88 + y ------(2)
substituting value of x in xy, we get
(88 + y) (y) = y² + 88y ------(1) to make it minimum we need to equate its derivative equal to zero.
derivative of (1) is 2y + 88
Equating it to zero, we get
2y + 88 = 0
subtracting 88 from both sides, we get
2y = -88
Dividing 2 from both sides, we get
y = -44 ------(3)
Substituting value of y from (3) in (2), we get
x = 88 - 44
x = 44
So, we get value of x as 44 and y as -44 to get their product as minimum.
