what is the quotient of negative 5 over negative 15
Answer: 1/3
Step-by-step explanation:
Quotient is another word for the solution to a division problem.
So in this case the quotient is the answer to -5/-15.
When you divide a negative by another negative, you get a positive answer. The same can be said about dividing a positive number by another positive number.
So, in this case, we can change -5/-15 to 5/15.
Now we just need to simplify by finding a GCF (greatest common factor)
Both 5 and 15 shares 5 as a factor, so divide them both by 5.
Then you would get 1/3 or .33333333333333333...

One of the 200 business majors at a college is to be chosen for the student senate. If 77 of these students are enrolled in a course in accounting, 64 are enrolled in business law, and 92 are enrolled in either courses, how many of the outcomes corresponds to the choice of a business major who is enrolled in both courses. Use a venn diagram.
If One of the 200 business majors at a college is to be chosen for the student senate. The outcomes that correspond to a business major who is enrolled in both accounting and business law is: x = 33 - y.
How many of the outcomes corresponds to the choice of a business major who is enrolled in both courses?Since we know that 92 students are enrolled in either course, we can write this number in the intersection of the two circles, which represents the number of students enrolled in both courses. Let x be the number of students enrolled only in accounting, and y be the number of students enrolled only in business law.
Our Venn diagram now looks like this:
Accounting
(77-x) (x)
___________
| |
Total | (92) | y
Business|___________|
Law | |
| x |
|___________|
(64-y) |
Total
Business
Majors
We know that there are 200 business majors in total, so the sum of the four regions in the diagram must add up to 200. Therefore:
x + y + (77-x) + (64-y) + 92 = 200
Simplifying this equation, we get:
x + y = 33
We want to find the number of outcomes that correspond to a business major who is enrolled in both accounting and business law. From the Venn diagram, we can see that this is represented by the intersection of the two circles, which has a value of x.
Therefore, there are x = 33 - y outcomes that correspond to a business major who is enrolled in both accounting and business law. The value of y can range from 0 (if all 33 students enrolled only in accounting) to 33 (if all 33 students enrolled only in business law).

Suppose that shoe sizes of American women have a bell-shaped distribution with a mean of 8.06
and a standard deviation of 1.52
. Using the empirical rule, what percentage of American women have shoe sizes that are between 6.54
and 9.58
?
An approximate of 68% of American women have shoe sizes that are between 6.54 and 9.58.
How can empirical rule be use to find the percentage?To use the empirical rule, we need to assume that the distribution of women's shoe sizes is approximately normal. Given a mean of 8.06 and a standard deviation of 1.52, we can standardize the values of 6.54 and 9.58 by subtracting the mean and dividing by the standard deviation:
Ζ1 = (6.54 - 8.06) / 1.52
Ζ1 = -1.00
Ζ2 = (9.58 - 8.06) / 1.52
Ζ2 = 1.00
The standardized values tell us that the value of 6.54 is 1 standard deviation below the mean, while the value of 9.58 is 1 standard deviation above the mean. According to the empirical rule, about 68% of the data falls within one standard deviation of the mean. Therefore, we can say that: [tex]P(6.54 < x < 9.58) = P(-1.00 < z < 1.00) = 68%[/tex]

A textile factory uses a 43 liter bucket of dye per 1 roll of fabric that is 1,067 feet long. If the factory has 4 buckets of dye, can it dye 5 rolls of fabric?
The factory has 172 litres of dye available.
What is litres?Liters (also spelled litres) is a unit of volume in the International System of Units (SI). It is commonly used to measure the volume of liquids, gases, and solids that can be poured or contained in a container. One liter is equivalent to 1000 cubic centimeters (cc) or milliliters (ml), and it is roughly equal to 1.057 quarts or 0.264 gallons.
In the given question,
First, we need to find out how much dye is needed for one roll of fabric. We know that 43 liters of dye are needed for 1 roll of fabric that is 1,067 feet long. Therefore, we can say that:
1 roll of fabric = 43 liters
1,067 feet
To find out how much dye is needed for 5 rolls of fabric, we can multiply both sides of this equation by 5:
5 rolls of fabric = 5 × 43 liters
1,067 feet = 215 liters
1,067 feet
So, 5 rolls of fabric would require 215 liters of dye.
Next, we need to check if the 4 buckets of dye are enough to dye 5 rolls of fabric. Each bucket contains 43 liters of dye, so 4 buckets would contain:
4 buckets of dye = 4 × 43 liters
= 172 liters
Therefore, the factory has 172 liters of dye available.
Since 215 liters of dye are required for 5 rolls of fabric, and the factory has only 172 liters of dye available, it cannot dye 5 rolls of fabric with the given amount of dye.

According to the information, the volume of the three-dimensional rhombus is 61.92 cm³.
How to calculate the volume of the three-dimensional rhombus?The three-dimensional rhombus is a geometric solid in the shape of a prism whose lateral faces are rhombuses and the bases are parallelograms. To calculate its volume, the area of the base must be multiplied by the height of the prism.
In this case, the height of the prism is 3 cm and the dimensions of the base rhombus are 5.2 cm wide and 8 cm long. Since the rhombus has two diagonals of equal length, its area can be calculated using the formula (major diagonal x minor diagonal) / 2.
First, the length of the diagonals of the base rhombus must be calculated using the Pythagorean theorem, since its width and length are known:
major diagonal = √(5.2/2)^2 + 8^2 = √(13.04 + 64) = √77.04 = 8.78 cmminor diagonal = √(5.2/2)^2 + 3^2 = √(13.04 + 9) = √22.04 = 4.69 cmThen, the area of the base rhombus can be calculated:
area = (major diagonal x minor diagonal) / 2 = (8.78 cm x 4.69 cm) / 2 = 20.64 cm²Finally, the volume of the prism can be calculated:
volume = base area x height = 20.64 cm² x 3 cm = 61.92 cm³Therefore, the volume of the three-dimensional rhombus is 61.92 cm³.

Therefore, Kallie will need to use a total of 6 teaspoons of water conditioner for all the water in 12 fish tanks.
What is equation?An equation is a mathematical statement that shows that two expressions are equal. It consists of two sides separated by an equal sign, with the expression on the left being equal to the expression on the right. Equations are used to represent various relationships and situations in mathematics and other fields, and are solved to find the values of variables that make the equation true.
Here,
First, we need to determine the total amount of water in all 12 fish tanks. Since each fish tank is filled with 20 quarts of water, the total amount of water in all 12 fish tanks is:
12 fish tanks * 20 quarts per fish tank = 240 quarts of water
To convert quarts to gallons, we divide by 4 (since there are 4 quarts in a gallon):
240 quarts / 4 quarts per gallon = 60 gallons of water
Now, we can use the given conversion factor to determine how many teaspoons of water conditioner are needed for 60 gallons of water. Since for every 10 gallons of water, Kallie uses 1 teaspoon of water conditioner, for 60 gallons of water, she will use:
60 gallons / 10 gallons per teaspoon = 6 teaspoons of water conditioner

If so, find the inverse.
ƒ-¹(x) =
F(x) is one-to-one, and it is invertible.
The inverse of f(x) is f^-1(x) = (x + 8)^(1/4)/∛3.
To determine if the function f(x) = 3x^4 - 8 is invertibleWe need to check if it is a one-to-one function.
A function is one-to-one if every element in the domain is paired with a unique element in the range.
To check if f(x) is one-to-one, we can use the horizontal line test. If no horizontal line intersects the graph of the function more than once, then the function is one-to-one.
Taking the derivative of f(x), we get:
f'(x) = 12x^3
Since f'(x) is always positive, f(x) is a strictly increasing function. This means that no two different inputs x1 and x2 can produce the same output f(x1) = f(x2).
Therefore, f(x) is one-to-one, and it is invertible.
To find the inverse of f(x), we can follow these steps:
Step 1: Replace f(x) with y:
y = 3x^4 - 8
Step 2: Solve for x in terms of y:
y + 8 = 3x^4
x^4 = (y + 8)/3
x = (y + 8)^(1/4)/∛3
Step 3: Replace x with f^-1(x):
f^-1(x) = (x + 8)^(1/4)/∛3
Therefore, the inverse of f(x) is f^-1(x) = (x + 8)^(1/4)/∛3.

sin(alpha-beta), sina=(11)/(12)in the II quadrant, Cos(beta)=(15)/(17) in quadrant IV, sin(alpha-beta)=
Answer:
Step-by-step explanation:
To find sin(alpha-beta), we can use the trigonometric identity:
sin(alpha - beta) = sin(alpha)cos(beta) - cos(alpha)sin(beta)
We are given that sin(alpha) = 11/12 in the second quadrant and cos(beta) = 15/17 in the fourth quadrant. We can use the Pythagorean theorem to find sin(beta):
sin^2(beta) + cos^2(beta) = 1
sin(beta) = sqrt(1 - cos^2(beta))
sin(beta) = sqrt(1 - (15/17)^2)
sin(beta) = sqrt(1 - 225/289)
sin(beta) = sqrt(64/289)
sin(beta) = 8/17 (since sin(beta) is positive in the fourth quadrant)
Now we can plug in the values we know into the identity:
sin(alpha - beta) = sin(alpha)cos(beta) - cos(alpha)sin(beta)
sin(alpha - beta) = (11/12)(15/17) - cos(alpha)(8/17)
We still need to find cos(alpha), which we can do using the Pythagorean identity:
sin^2(alpha) + cos^2(alpha) = 1
cos(alpha) = sqrt(1 - sin^2(alpha))
cos(alpha) = sqrt(1 - (11/12)^2)
cos(alpha) = sqrt(23/144)
Now we can substitute this value into the expression for sin(alpha - beta):
sin(alpha - beta) = (11/12)(15/17) - cos(alpha)(8/17)
sin(alpha - beta) = (11/12)(15/17) - sqrt(23/144)(8/17)
sin(alpha - beta) ≈ 0.210
Therefore, sin(alpha - beta) is approximately equal to 0.210.

the number of students that offer Mathematics is 11
Calculating the number of students that offer Mathematics?The sum of the fractions of the pie chart should be equal to 1 since it represents the whole class of 80 students.
Let's write the fractions for each subject in terms of x:
Math: 5x/80
French: (16x-24)/80
English: (6x+12)/80
Hausa: (4x+12)/80

The sum of these fractions must equal 1:
5x/80 + (16x-24)/80 + (6x+12)/80 + (4x+12)/80 + 5x/80 = 1
Multiplying both sides by the least common multiple (LCM) of the denominators, which is 80, we get:
5x + 16x - 24 + 6x + 12 + 4x + 12 + 5x = 80
Combining like terms, we get:

An angle meaning is what?The place where the lines that make up a skew's ends meet determines the size of its largest and smallest walls. It is conceivable for two routes to cross at a junction. Angle is another outcome of two things interacting. They mirror dihedral shapes the most. A two-dimensional curve can be created by arranging two line beams in various configurations between their ends.
Here,
Angle QRM counts 90 degrees because it is a right angle (represented by the square in the diagram).
We can use the knowledge that the sum of all angles in a straight line is 180 degrees to determine angle QPR. A straight line is formed by angles QPB and BPR, so:
=> Angle QPB + Angle BPR = 180°.
Given that the triangular is equilateral, angle QPB is equal to 60 degrees.
=> BPR angle = 180 - 60 = 120 degrees.
We can now use the knowledge that a triangle's total angles equal 180 degrees to determine angle QMR. Triangle formed by angles QMR, QRM, and BMR results in:
Angles QMR, QRM, and BMR add up to 180 degrees.
=> Angle QMR+90+120=180

[tex]x = (-b ± sqrt(b^2 - 4ac)) / 2a[/tex]The three consecutive integers are 5/2, 7/2, and 9/2. We can check that this solution works by squaring the third integer (9/2), adding it to the first integer (5/2), and verifying that the sum is indeed 130:
[tex](5/2) + (9/2)^2 = 130[/tex]
Let's call the first of the three consecutive integers "x". Then, the next two consecutive integers are x+1 and x+2.
The problem tells us that the square of the third integer (which is x+2) added to the first integer (which is x) is 130. In equation form, we can write:
[tex]x + (x+2)^2 = 130[/tex]
Simplifying the equation, we can expand the square:
[tex]x + x^2 + 4x + 4 = 130[/tex]
Combining like terms:
[tex]x^2 + 5x - 126 = 0[/tex]
Now we can use the quadratic formula to solve for x:
x = -b ± [tex]sqrt(b^2 - 4ac)) / 2a[/tex]
where a = 1, b = 5, and c = -126. Plugging these values into the formula, we get:
x = (-5 ±[tex]sqrt(5^2 - 4(1)(-126))) / 2(1)[/tex]
x = (-5 ± [tex]sqrt(625)) / 2[/tex]
x = (-5 ±25) / 2
So, x could be either -15/2 or 5/2. However, we are looking for three consecutive integers, so we can eliminate the negative value and choose x = 5/2.
Therefore, the three consecutive integers are 5/2, 7/2, and 9/2. We can check that this solution works by squaring the third integer (9/2), adding it to the first integer (5/2), and verifying that the sum is indeed 130:

This is a guess but I think it's 5 min per table.
Step-by-step explanation:
The reason being:
if we know that she has 9 tables to get to and each table can seat 4 people, we would have to multiply both numbers to find how many TOTAL people are in the restaurant during the first few hours.
9x4 = 36 people in total
then, we need to convert 3hrs into minutes to get a more accurate rep as to how much time she would spend at each table (she isn't going to spend the entire 3 hrs with only one table now, is she?)
so for this, we convert 3hrs into minutes
1 min = 60 secs
1 hr = 60 minutes
3hrs -> 60 x 3 = 180 minutes
now, to understand how many time she spends at each table, we need to figure out by dividing the # of people by the amount of minutes.
180 minutes/36 people = 5 mins per table.
