The question requires the application of combination formulas to calculate the number of possible subcommittees with specific party member composition requirements.
Explanation:The question deals with combinations in mathematics, specifically combinatorial calculation to determine the number of ways a subcommittee can be formed given certain restrictions on a party composition.
Part 1:
To find out how many subcommittees can be formed containing exactly 3 Republicans and 4 Democrats, we use the combination formula which is C(n, k) = n! / (k! * (n - k)!), where n is the total number of items to choose from, k is the number of items to choose, and '!' denotes factorial. There are 6 Republicans, so we can choose 3 of them in C(6, 3) ways and there are 8 Democrats from which we can choose 4 in C(8, 4) ways. The total number of such subcommittees is the product of these two combinations.
Part 2:
For the second part, we consider subcommittees with at least 1 and no more than 3 Republicans. This means we must calculate the sum of subcommittees for when there are exactly 1, 2, or 3 Republicans, combined with the appropriate number of Democrats to make a total of 7 members. We use the combination formula again for each scenario and add the results together.

Select the following series as arithmetic, geometric, or neither. 1 + 2 + 3 + 4 + . . . + 10
The following series is an arithmetic series. Because the progressive term has a difference of 1.
What is a sequence?It is defined as the systematic way of representing the data that follows a certain rule of arithmetic.
The given equation is;
1 + 2 + 3 + 4 + . . . + 10
The series is arithmetic in nature. The typical difference in the progression is 1. Because it has a plus sign, which indicates an arithmetic progression.
Hence, the following series is an arithmetic series.

For the rational equation, x^2+5x+6/x+3=1 , what is a valid value of x?.
Answer:
B. -1
Step-by-step explanation:
We have the equation, [tex]\frac{x^{2}+5x+6}{x+3}=1[/tex].
Now, factorizing the polynomial [tex]x^{2}+5x+6[/tex], we get that the factors of the polynomial are (x+3) and (x+2).
So, we get,
[tex]\frac{x^{2}+5x+6}{x+3}=1[/tex]
i.e. [tex]\frac{(x+3)(x+2)}{x+3}=1[/tex]
i.e. x + 2 = 1
i.e. x = -1.
Hence, we get that the value of x is -1.

What is the value of z in the equation 11 + z = 6?
66
5
−5
1
Answer:
z = -5
Step-by-step explanation:
To find the value of z in the equation 11 + z = 6
we will simply subtract 11 from both-side of the equation. That is;
11 + z = 6
Subtract 11 from both-side of the equation
11 - 11 + z = 6 - 11
(On the left-hand side of the equation 11 will be subtracted from 11 which gives zero, thereby leaving us with just z while on the right-hand side of the equation 11 will be subtracted from 6 which will give negative 5)
z = -5

Using complete sentences, explain the key features of the graph of the sine function.
Express 18.48 ( 48 bar) in the form of p/q where p and q are integers and q is not equal to 0.
We have to express [tex] 18.\bar{48} [/tex] in the form of [tex] \frac{p}{q} [/tex] where p and q are integers and q is not equal to zero.
Let x = [tex] 18.\bar{48} [/tex]
Multiplying the given equation by 100, we get
[tex] 100x = 1848.48484848... [/tex]
[tex] 100x = 1830+ 18.48484848... [/tex]
[tex] 100x = 1830+ 18.\bar{48} [/tex]
[tex] 100x = 1830+ x [/tex]
[tex] 99x=1830 [/tex]
[tex] x=\frac{1830}{99} [/tex]
Therefore, [tex] 18.\bar{48} [/tex] is represented as [tex] x=\frac{1830}{99} [/tex] in the form of [tex] \frac{p}{q} [/tex]
Lindsey’s college will cost her a total of $6,000 a year for the next four years. She is also
foregoing making $26,000 a year at the local mall. However, she will be able to make
about $8,000 a year while going to school. What is her total investment in education?
$24,000
$26,000
$72,000
$96,000
Karam anticipates spending $8,400 a year for the next five years on his college education. He will also forgo making $12,000 a year during this time. How much will he invest in his education?
$42,000
$102,000
$60,000
$12,000
Her total investment in education is $96,000, the correct option is D.
What is Algebra?Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.
The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.
We are given that;
Total= $6,000
At local mall=$26,000
Now,
To find the total investment in education, we need to consider both the direct costs and the opportunity costs of going to college. The direct costs are the expenses that Lindsey has to pay for her education, such as tuition, fees, books, etc. The opportunity costs are the income that Lindsey could have earned if she did not go to college, such as working at the local mall.
The direct costs of going to college are $6,000 a year for four years, which is $24,000 in total.
The opportunity costs of going to college are $26,000 a year minus $8,000 a year for four years, which is $18,000 a year or $72,000 in total. This is because Lindsey could have earned $26,000 a year at the mall, but she is only earning $8,000 a year while going to school.
The total investment in education is the sum of the direct costs and the opportunity costs, which is
$24,000 + $72,000
= $96,000.
Therefore, by algebra the answer will be $96,000.

Given cosx=1213 and sinx=513 .
What is ratio for tan x ?
leave answer as a fraction in simplest form
Remember to show all of you work for credit!
Q1: Given sin(x+22)° = cos(2x−7)°
Using the concept of Right triangles and Trigonometric ratios, we can use a formula given as follows :-
If, sin(A) = cos(B). Then we must have A + B = 90 degrees.
We have sin(x+22)° = cos(2x−7)°
Then it must be true that (x+22)° + (2x−7)° = 90 degrees.
(x + 22) + (2x - 7) = 90
3x + 15 = 90
3x + 15 - 15 = 90 - 15
3x = 75
[tex] \frac{3x}{3} =\frac{75}{3} \\\\x = 25 \;degrees [/tex]
Hence, x = 25 degrees is the final answer.
Q2: Given cos(x) = 1213 and sin(x) = 513.
It says to find ratio of tan(x).
Using the concepts of Trigonometric ratios, We can the formula that relates all three functions i.e. sin(x), cos(x), and tan(x).
tan(x) = [tex] \frac{sin(x)}{cos(x)} [/tex]
We can plug the given values in the formula.
[tex] tan(x) = \frac{513}{1213} [/tex] is the final answer.

What law does static electricity illustrate?
A. Ohm's law
B. Law of Conservation of Motion
C. Law of Conservation of Energy
D. Law of Conservation of Charge
Would this be D?
I know its not math...>:P
Static electricity illustrates or mostly related to the Law of Conservation of Charge. This law states that the charge of matter is constant and it will only change if there is the entrance of new charge or there is a removal of charge. This is the same with static electricity since charge of static electricity is constant.
