Wen is factoring the polynomial, which has four terms. 6x3 – 12x2 7x – 14 6x2 (x – 2) 7(x – 2) which is the completely factored form of his polynomial?
Completely factored form of Wen's polynomial is (6x² + 7) (x-2).
What is a polynomial?
An algebraic expression called a polynomial includes coefficients and variables. Indeterminates are another name for variables. For a polynomial expression, we can do mathematical operations like addition, subtraction, multiplication, and positive integer exponents, but division by variable is not possible. Although a polynomial can have multiple number of terms, it can't be infinite.
Factorizing the polynomial
Complete factorization of a polynomial results in products-of-sums
Given polynomial is,
6x³ - 12x² + 7x - 14
This polynomial can be factorized as follows,
6x² (x - 2) + 7(x - 2)
Now, we can factor out the common term (x-2) form each term on either side of the plus operator. thus, we get the following factors,
(6x² + 7) (x-2)

After four years of higher education, Julia just graduated with a Bachelor's degree in Engineering from USC where the annual cost of tuition was $22,000. She paid for college by earning $11,000 annually through the work study program and receiving an annual scholarship. She covered the remainder of the costs by taking out $12,000 in student loans. If she didn't fund her education with savings or grant money, what was the amount of Julia's annual academic scholarship?
Answer:
$32,000
Step-by-step explanation:
overall cost for 4 years was $88,000. She made $44,000 after 4 years. After all 4 years she had to take out $12,000 to pay. 88,000-44,000=44,000 44,000-12,000=32,000
Answer:
$8,000
Step-by-step explanation:
Tuition per year: $22,000
Work Study Earnings per year: $11,000
Student Loans per year: $12,000 / 4 = $3,000
Annual Academic Scholarship per year: $x
Per Year Calculations
$22,000 = $11,000 + $3,000 + $x
$x = $22,000 - $11,000 - $3,000
$x = $8,000
To use the two sample t procedure to perform a significance test on the difference of two means, we assume:
We assume that the population standard deviation are known, the samples from each population are independent, the population is normally distributed if we use t test of two samples.
Given T test of significance has been used.
T test is a statistical test that is like z test. Z test is used when n>30 and t test is used when n<30. It is used in hypothesis testing.
We know that there are many test which can be used to test a hypothesis.
The requirements to perform a two sample t procedure are as follows:
1)The two samples have equal variance. Hence the variance should be known.
2) The samples for which the two sample t procedure is performed must be independent.
3) The data are in alignment with the normal distribution probability.
4) The sample are random samples taken from different respective population.
Hence when two sample t procedure is performed we have to assume population standard deviation is known and population is normally distributed.

In the figure below AOD is a diameter of the circle cetre O. BC is a chord parallel to AD. FE is a tangent to the circle. OF bisects angle COD. Angle BCE = angle COE = 20° BC cuts OE at X
Calculate;
(a) angle BOE
(b) angle BEC
(c) angle CEF
(d) angle OXC
(e) angle OFE
Step-by-step explanation:
∠ACB=90∘
[∠ from diameter]
In ΔACB
∠A+∠ACB+∠CBA=180∘
∠CBA=180∘
−(90+30)
∠CBA=60∘ (1)
In △OCB
OC=OB
So, ∠OCB=∠OBC
[The sides are equal]
∠OCB=60∘
∠OCD=90∘
∠OCB+∠BCD=90°
∠BCD=30∘ (2)
∠CBO=∠BCO+∠CDB

Find the remainder of the division. 2001 • 2002 • 2003 + 2004^3 by 7.
Show steps.
Answer:
[tex]1[/tex]
Step-by-step explanation:
The gist of modular arithmetic in a nutshell: the numbers [tex]a[/tex] and [tex]b[/tex] are considered to be congruent by their modulus [tex]m[/tex] if [tex]m[/tex] is a divisor of their difference.
In mathematics: [tex]a \equiv_{m} b \Leftrightarrow (a - b) \vdots m[/tex]
Exemplifying this: [tex]6 \equiv_{7} -1[/tex] because [tex]6 - (-1) = 6 + 1 = 7[/tex], [tex]7 \vdots 7[/tex].
Let us have following equivalences: [tex]a \equiv_{m} b[/tex] and [tex]c \equiv_{m} d[/tex], then: [tex](a - b) \vdots m[/tex] and [tex](c - d) \vdots m[/tex] by definition.
Properties:
1. [tex]a + c \equiv_{m} b + d \Leftrightarrow ((a + c) - (b + d)) \vdots m \Leftrightarrow (a + c - b - d) \vdots m \Leftrightarrow ((a - b) + (c - d)) \vdots m[/tex].
2. [tex]a - c \equiv_{m} b - d \Leftrightarrow ((a - c) - (b - d)) \vdots m \Leftrightarrow (a - c - b + d) \vdots m \Leftrightarrow ((a - b) - (c - d)) \vdots m[/tex].
3. [tex]ac \equiv_{m} bd \Leftrightarrow (ac - bd) \vdots m \Leftrightarrow (ac - bc - bd + bc) \vdots m \Leftrightarrow (c(a - b) + b(c - d)) \vdots m[/tex].
4. What if we have [tex]a \equiv_{m} b[/tex] twice? If we abide by property 3, we can come to the conclusion that [tex]a^2 \equiv_m b^2[/tex]. It is fair enough that there is room for the equivalence [tex]a^n \equiv_{m} b^n[/tex].
[tex]2001 * 2002 * 2003 + 2004^3 = 2002 * (2001 * 2003) + 2004^3 \equiv_{7} 0 * (2001 * 2003) + 2^3 \equiv_{7} 0 + 8 \equiv_{7} 8 \equiv_{7} 1[/tex]
Notice that [tex]2002 \vdots 7[/tex] already. There is no need to consider the rest multipliers because the product is [tex]0[/tex] anyways, we can cut corners in this regard.
We used property 4.
Recapitulating this: our remainder is [tex]1[/tex].

As a result, the ratio of the number of orange candies to that of lemon became 11:15. How many lemon candies did he give his friend
30 lemon candies he give his friend.
It is given that a boy had 320 candies. There were 2 flavors. 7/16 were orange flavor and the rest were lemon. He gave his friend 30 orange candies and some lemon ones.
320 (7/16) = 140 were orange
320 - 140 = 180 were lemon
Let x be the number of lemon ones he gave away
So,
[ 140 - 30 ] / [ 180 - x ] = 11/15
110 = (11/15) ( 180 - x )
(15/11) (110) = 180 - x

What does it mean for an event to be unusual? why should the cutoff for identifying unusual events not always be 0. 05?.
An unusual event is an occurrence that has a low probability of happening. The cutoff for identifying unusual events not always be 0.05, because it is not always a good idea to utilize the same cutoff to spot unexpected occurrences.
What is an unusual event?An unusual event is an occurrence that has a low probability of happening.
If an event is improbable, its likelihood is zero. If an occurrence is unavoidable, its probability is one.
The probability of an event happening increases as it gets closer to 1. An occurrence that has a probability of 0.375, for instance, is more likely to happen than one with a probability of 0.125.
The less likely an event is to occur, the closer the probability is to 0. An unusual event is what this kind of event falls under. A probability of 5%, or 0.05, is typically regarded as unusual event.

y = mx + c ( m is the slope and c the y- intercept )
calculate m using the slope formula
