Answer: List 2

Mark the midpoint between 1/6 and 1/2 (see diagram below)

======================================================

Explanation:

There are 3 meats (ham, turkey, bologna) and 2 vegetables (carrots, celery).

This gives 3*2 = 6 different combos of meat plus a vegetable. This is where we can only pick one of each type.

The 6 different combos are shown in  list 2  

List 1 is not correct because you can choose one vegetable only, and not have both.

----------

Look through list 2 and circle the options that say "ham, carrots" and "turkey, carrots". There are 2 items that are circled. This is out of 6 total.

We arrive at the probability 2/6 = 1/3

The fraction 2/6, aka 1/3, is located at the halfway point between 1/6 and 1/2. This is because 1/6+1/2 = 1/6+3/6 = 4/6, which divides in half to get 2/6.

See the diagram below.

Answer:

69

Step-by-step explanation:

The central angle is twice the inscribed angle. So the angle that is behind the one equal to 2x is equal to x. We know that the opposite angles in a circle add up to 180. Therefore, we can solve for x:

[tex]x + x + 42 = 180$^{\circ}$\\\\2x = 180$^{\circ}$ - 42$^{\circ}$\\\\2x = 138$^{\circ}$\\\\x = 69$^{\circ}$[/tex]

Answer: 8, 9, 10

A function is a procedure or a relation that links each element of a non-empty set A, at least, to one element of a different non-empty set B. In mathematics, a relation f between two sets, A and B, is referred to as the function's domain and co-domain, respectively. f = {(a,b)| for all a ∈ A, b ∈ B}

If each element of set A has exactly one image in set B, then the relation is said to be a function.

A function is a relation from a non-empty set B such that its domain is A and no two different ordered pairs in f share the same first element.

The price that is 3 standard deviations above the mean is $18,500. The price that is 2 standard deviations below the mean is $15,500.

The percentage of buyers who paid between $16,500 and $17,500 is approximately 13.6%.
The percentage of buyers who paid between $17,000 and $18,000 is approximately 34.1%.
The percentage of buyers who paid less than $16,000 is approximately 2.3%.

It's important to note that these values are approximate and based on the assumption that the prices paid for the car are approximately normally distributed with a mean of $17,000 and a standard deviation of $500. It's also worth mentioning that these percentages are based on the standard normal distribution table which assumes a normal distribution with a mean of 0 and a standard deviation of 1.

x²= 4 and 3x=9 is not an empty set because there is no element we can say that is an empty set but there is an element, so it is not an empty set.

In arithmetic, the empty set is a completely unique set having no elements; its size or cardinality (depending on elements in a fixed) is 0. some axiomatic set theories make certain that the empty set exists by including an axiom of the empty set, whilst in different theories, its lifestyles may be deduced. Many feasible properties of sets are vacuously genuine for the empty set.

Any set aside from the empty set is known as non-empty. In a few textbooks and popularizations, the empty set is known as the "null set". but, a null set is a distinct belief inside the context of the measure concept, wherein it describes a hard and fast degree 0 (which is not always empty). The empty set may also be referred to as the void set.

The solution for the equations is at x = -1 and y = -3.

2: the system of equations has the same slope and the same y-intercept so the system of equations has infinitely many solutions.

When an algebraic equation is graphed, it always results in a straight line since each term in a linear equation has an exponent of 1. For this reason, it is referred to as a "linear equation."

There are both one-variable and two-variable linear equations.

Given the equations,

-2x + 4y = -10

2x + 2y = -8

adding both the equations so -2x and +2x will be eliminated

-2x + 4y + 2x + 2y = -10 - 8

6y = -18

y = -18/6

y = -3

substitute the value of y in equation 2x + 2y = -8

2x + 2(-3) = -8

2x = -8 + 6

x = -1

2: Given equations y = -x + 5 .........(1)

y + x = 5 .........(2)

equation 2 can be written as,

y = -x + 5

so both the equations have the same slope and the same value of y-intercept,

so the line overlaps each other and has infinitely many solutions.

By using the fact that the triangles are similar, we can see that u = 8, then the length of side PR is:

PR = 68

We know that R is the midpoint of QS and P is the midpoint of QT, this means that tiangles QRP and QST are similar triangles, and that the scale factor between them is 2.

Then we know that:

ST = 2*RP

We know that:

RP = 4u + 2

ST = u + 60

Then we can write the linear equation:

u + 60 = 2*(4u + 2)

u + 60 = 8u + 4

60 - 4 = 8u - u

There are 4 rows of Soprano. The concept of algebraic manipulation is used to solve the problem.

Given the information that there are 64 fingers in total and 8 fingers in each row of the Tenor, I was able to determine that there are 32 fingers in the Tenor rows by multiplying 8 fingers/row x 4 rows.

Then, We subtracted the number of fingers in the Tenor rows (32 fingers) from the total number of fingers (64 fingers) to find the number of fingers in the Soprano rows, which is also 32 fingers.

Finally, We divided the number of fingers in the Soprano rows by the number of fingers per row (8 fingers/row) to find the number of rows of Soprano, which is 4 rows.

If there are 64 fingers in total and 8 fingers in each row of the Tenor, then there are 8 fingers / row x 4 rows = 32 fingers in the Tenor rows.

Since there are 64 fingers in total and 32 fingers in the Tenor rows, then there are 64 fingers - 32 fingers = 32 fingers in the Soprano rows.

Therefore, there are 32 fingers / 8 fingers/row = 4 rows of Soprano.

a) To find the company's revenue and costs if it sells 2000 shirts, we can substitute 2000 for x in the given revenue and cost functions:

The definition of an equation in algebra is a mathematical statement that demonstrates the equality of two mathematical expressions. For instance, the equation 3x + 5 = 14 consists of the two equations 3x + 5 and 14, which are separated by the 'equal' sign.

Revenue: r(x) = 10x, so r(2000) = 10(2000) = $20,000

Costs: c(x) = 3x + 9000, so c(2000) = 3(2000) + 9000 = $15,000

b) The profit function, p(x), is the difference between the revenue function and the cost function. So, the profit function for this company is:

p(x) = r(x) - c(x) = 10x - (3x + 9000) = 7x - 9000

c) To find the company's profit in 2012, when it sold 5000 shirts, we substitute 5000 for x in the profit function:

p(5000) = 7(5000) - 9000 = $20,000

Number:

Numbers are mathematical objects used for counting, measuring, and labeling. The original example is the natural numbers 1, 2, 3, 4, etc. [1] Numbers can be linguistically represented by numerals. More generally, individual numbers can be represented by symbols called digits. For example, "5" is the number representing the number five. Since only a relatively small number of symbols can be remembered, basic numbers are usually organized into number systems, which are systematic ways of representing each number. The most common number system is the Hindu-Arabic number system, which can represent any number using combinations of 10 basic numeral symbols called digits.  In common parlance, a number is indistinguishable from the number it represents.

Greater than Number:

It is a mathematical term used to compare two quantities and to establish a relationship between two quantities in which one term is greater than the other. The terms greater than, less than, and equal are used to compare two numbers, amounts, or amounts. Each term has a separate letter. B.

a) The Coulomb's law equation for the force between two charges q1 and q2 is given by:

F = k(q1q2)/r2

Where k is the Coulomb's constant and r is the distance between the two charges.

Using this equation, the force on q1 due to q2 can be calculated as:

F12 = (8.99x109 N m2/C2)(8.00x10-6C)(-5.00x10-6C)/(1.00m)2

F12 = -44.8x10-6 N

Similarly, the force on q1 due to q3 can be calculated as:

F13 = (8.99x109 N m2/C2)(8.00x10-6C)(5.00x10-6C)/(2.00m)2

F13 = 55.2x10-6 N

The net force on q1 can be calculated as the vector sum of F12 and F13:
