1. 18x^3-2x^2+4x-1
1.1 How many terms are in 18x^3-2x^2+4x-1
The polynomial 18x³ - 2x² + 4x - 1 consists of four terms.
The number of terms in a polynomial helps when performing operations like simplification, factoring, or evaluating expressions.
The polynomial 18x³ - 2x² + 4x - 1 consists of four terms.
In order to determine the number of terms in a polynomial, we count the number of distinct algebraic expressions separated by addition or subtraction operations.
In this polynomial, we have:
Term 1: 18x³ (This is the term with the highest degree, which is 3 in this case, and it includes the coefficient 18.)
Term 2: -2x² (This term has a degree of 2 and a coefficient of -2.)
Term 3: 4x (This term has a degree of 1 and a coefficient of 4.)
Term 4: -1 (This is a constant term with a degree of 0.)
We can see that there are four distinct terms separated by addition and subtraction operations:
18x³, -2x², 4x, and -1.

PLEASE HELP DUEEE NOW !!!A diagram of a roundabout that is being designed to improve driver safety on a busy road is shown. The radius of the circular field planned for landscaping is 27.5 feet. What is the approximate distance around the outside of the circular field?
A. 345.4 feet
B. 172.7 feet
C. 86.35 feet
D. 2,323.1 feet
The approximate distance around the outside of the circular field is the circumference = 172.7 feet and the correct option is B.
How to evaluate for the circumference of a circleTo calculate the circumference of a circle, multiply the diameter of the circle with π (pi). The circumference can also be calculated by multiplying 2×radius with pi (π = 3.14).
We shall derive the approximate distance around the outside of the circular field by calculating for the circumference as follows:
Radius of the circular feild = 27.5
circumference of the circular feild = 2 × 27.5 feet × 3.14
circumference of the circular feild = 55 feet × 3.14
circumference of the circular feild = 172.7 feet.
Therefore, the approximate distance around the outside of the circular field is derived as the circumference which is equal to 172.7 feet.

Suppose a population contains 20,000 people. All else being equal, a study
based on a population sample that includes which of the following numbers
of respondents would be the most reliable?
A. 200
OB. 20
C. 2000
D. 2
A study based on a population sample that includes 2000 respondents would be the most reliable out of the given options.
In statistical analysis, the reliability of a study depends on the representativeness and size of the sample.
A larger sample size generally provides more reliable results as it reduces the sampling error and increases the precision of the estimates.
Given that the population contains 20,000 people, we need to consider which number of respondents would yield the most reliable study.
Option A: 200 respondents
This represents only 1% of the population.
While it is better than having just 2 respondents, it may not be sufficient to accurately capture the characteristics of the entire population.
Option B: 20 respondents
This represents only 0.1% of the population.
With such a small sample size, the study would likely suffer from a high sampling error and may not provide reliable results.
Option C: 2000 respondents
This represents 10% of the population.
While it is a larger sample size compared to the previous options, it still only captures a fraction of the population.
The study may provide reasonably reliable results, but there is room for potential sampling error.
Option D: 2 respondents
This represents an extremely small sample size, accounting for only 0.01% of the population.
With such a small sample, the study would be highly susceptible to sampling bias and would likely yield unreliable results.
Based on the options provided, option C with 2000 respondents would be the most reliable study.
Although it does not include the entire population, a sample size of 2000 respondents provides a larger representation of the population and reduces the potential for sampling error.
However, it's important to note that the reliability of a study depends not only on sample size but also on the sampling method, data collection techniques, and other factors that ensure representativeness.

The third term and the sixth term of A geomatric sequence are 2 and 16 respectively. Find the first term and the common ratio
The first term of the geometric sequence is 1/2 and the common ratio is 2.
What is the geometric sequence?
A geometric sequence is a sequence of numbers in which each term after the first is obtained by multiplying the previous term by a fixed number called the common ratio. The general form of a geometric sequence is:
a, ar, ar², ar³, ar⁴, ...
where 'a' is the first term, 'r' is the common ratio, and the subscripts represent the position of the term in the sequence.
Let's denote the first term of the geometric sequence by "a" and the common ratio by "r".
We know that the third term of the sequence is 2, which means that:
a * r² = 2 (1)
We also know that the sixth term of the sequence is 16, which means that:
a * r⁵ = 16 (2)
Now we can solve for "a" and "r" by dividing equation (2) by equation (1):
(a * r⁵)/(a * r²) = 16/2
Simplifying, we get:
r³ = 8
Taking the cube root of both sides, we get:
r = 2
Now we can use equation (1) to solve for "a":
a * 2² = 2
Simplifying, we get:
4a = 2
a = 1/2
Therefore, the first term of the geometric sequence is 1/2 and the common ratio is 2.

g in a school course, course x is related to course y if all the students who take course x are also in course y
This question is incomplete , I am answering this question in general as per my knowledge.
No, because you gave T a Boolean when T expected a student as its first argument and a course as its second parameter. This will be less formal if.
The expected,
T(‘‘user2012813",‘‘discrete math")=true
However, the function F(x) and A both yield either true or false (y). Thus, you are attempting to assess
T(F(‘‘user2012813"),A(‘‘discrete math"))=T(true, false)= NULL
Only the first formulation makes sense, but after relations are established, these kinds of structures can be used.
Null functions as both a value and a pointer in computer programming. A built-in constant called null has a value of zero. It is the same as how strings in C are terminated with the letter 0.
Null is another possible value for a pointer, and unless the CPU supports a unique bit pattern for a null pointer, it has the same value as zero.

There are 12 animals in the barn. Some are chickens and some are pigs.
There are 32 legs in all. How many of each animal are there?
Answer:
4 pigs and 8 chickens.
Step-by-step explanation:
Let number of chickens be c and number of pigs be p:
Animals:
c + p = 12
Legs:
2c + 4p = 32
Multiply the first equation by 2:
2c + 2p = 24
Subtract this from the second equation:
2c - 2c + 4p - 2p = 32 - 24
2p = 8
p = 4
and therefore c = 12 - 4 = 8.
Answer:
the answer is 10 for chicken and 10 for pigs

The pool has a fixed area, A m2, but the pool's dimensions can vary (For instance, a 4 m2 pool can have infinitely many length-width combinations, including 2×2, 4×1, 1×4, or π2×8π).The width of the pool deck extends beyond the pool on both sides, as does the length of the pool deck. Because the pool has a fixed area, the pool length depends on the pool width and vice versa.The width in the applet, W, varies between .5 meters and 12 meters. Find the minimum area for a pool and deck built as in the application such that the pool's area is 1800 square meters, the deck extends an extra 10 meters wide on both sides of the pool, and the deck extends an extra 5 meters long on the corresponding sides of the pool. Your solution should contain a justification for why your found area is indeed the minimizing area.
The minimal size for a pool and deck constructed as in the application, with the deck extending an additional 10 meters is 1400 meter square.

We have to find the minimal size for a pool and deck constructed as in the application, with the deck extending an additional 10 meters on each side of the pool and a further 5 meters along the corresponding sides of the pool. The pool's area is 1800 square meters.
We know that,
Area of the Total space = (l+10)(b+20)
Here,
b=1800/l
l= 30
So,
b=60
Area of the total space is (30+10)(60+20) = 40×80 = 3200 m²
The minimum area of deck = 3200-1800 = 1400 m²

P( being chosen at least 5 times)
USing binomial. Distribution
P(X =x) = nCr * p^x * (1-p)^n-x
To save computation time, we can use the binomial distribution calculator :
P(x≥5):p(x = 5) + p(x = 6) + p(x =7) + p(x = 8) +. P(x = 9) = 0.00136
C) What is the expected number of players who are chosen for random drug testing at least 4 times in the first 9 weeks of the foosball season?
