According to the solving the  Polynomial  Standard Form of the given equation is :

3x^2-7x-17.

When expressing a polynomial in its standard form, the greatest degree of terms are written first, followed by the next degree, and so on. When x is the variable and ai are coefficients, the polynomial has the conventional form f(x) = anxn + an-1xn-1 + an-2xn-2 +... + a1x + a0.

f(x)= x-7

g(x)= 3x^2-7x-10

f(x)= x-7 by substituting in the value of  g into f.

f(3x^2-7x-10) =  (3x^2-7x-10)-7

                     = 3x^2-7x-17

Answer:  Choice A)   [tex]\boldsymbol{78.67\% \ \pm \ 9.46\%}[/tex]

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

Explanation:

phat = 59/75 = 0.7867 = 78.67% approximately is the sample proportion

n = 75 is the sample size

Your teacher doesn't mention a confidence level, so I'll assume it's the default 95%.

Let's compute the margin of error at 95% confidence

E = z*sqrt(phat*(1-phat)/n)

E = 1.96*sqrt(0.7867*(1-0.7867)/75)

E = 0.0927 approximately

E = 9.27% approximately

Unfortunately the margin of error 9.27% isn't listed among the four answer choices, but let's change the z = 1.96 to z = 2 instead.

Recalculate the margin of error.

E = z*sqrt(phat*(1-phat)/n)

E = 2*sqrt(0.7867*(1-0.7867)/75)

E = 0.0946 approximately

E = 9.46% approximately

This margin of error is listed among the four answer choices.

------------------

We found that

The confidence interval in the format [tex]\text{phat} \ \pm \ \text{E}[/tex] is approximately [tex]78.67\% \ \pm \ 9.46\%[/tex] which points us to choice A as the answer.

Answer:

[tex]\textsf{a)} \quad 78.67\% \pm 9.46\%[/tex]

or d) None of the answers are correct.  (Please see notes below).

Step-by-step explanation:

P-hat is the probability that a given outcome will occur given a specified sample size.

[tex]\boxed{\begin{minipage}{7.5 cm}\underline{P-hat formula}\\\\$\hat{p}=\dfrac{X}{n}$\\\\where:\\\phantom{ww}$\bullet$ $\hat{p}$ is the probability. \\ \phantom{ww}$\bullet$ $X$ is the number of occurrences of an event. \\ \phantom{ww}$\bullet$ $n$ is the sample size.\\\end{minipage}}[/tex]

Given:

Substitute the given values into the formula to find p-hat:

[tex]\implies \hat{p}=\dfrac{59}{75} =0.78666666...[/tex]

The critical value for a 95% confidence level using normal distribution is:

[tex]z=1.9600\;\;\sf (4\;d.p.)[/tex]

[tex]\boxed{\begin{minipage}{5.2 cm}\underline{Margin of error}\\\\$ME=z \cdot \sqrt{\dfrac{\hat{p}(1-\hat{p})}{n}}$\\\\where:\\\phantom{ww}$\bullet$ $z$ is the critical value. \\ \phantom{ww}$\bullet$ $\hat{p}$ is the sample proportion. \\ \phantom{ww}$\bullet$ $n$ is the sample size.\\\end{minipage}}[/tex]

Substitute the given values into the margin of error formula:

[tex]\implies ME=1.9600 \cdot \sqrt{\dfrac{\dfrac{59}{75}\left(1-\dfrac{59}{75}\right)}{75}}[/tex]

[tex]\implies ME=0.092715036...[/tex]

Therefore, an estimate of the proportion of young-adult novels that include a love triangle (including a margin of error) is:

[tex]\implies \hat{p}\pm ME[/tex]

[tex]\implies 0.7867\pm 0.0927[/tex]

[tex]\implies 78.67\% \pm 9.27\%[/tex]

This result if not given in the list of answer options.  However, the final result depends on the accuracy of the z-score and p-hat used in the calculations.  

If we round the critical value to the nearest integer then:

[tex]\implies z=2[/tex]

Substitute the rounded z-value into the margin of error formula:

[tex]\implies ME=2\cdot \sqrt{\dfrac{\dfrac{59}{75}\left(1-\dfrac{59}{75}\right)}{75}}[/tex]

[tex]\implies ME=0.094607180...[/tex]

Therefore, an estimate of the proportion of young-adult novels that include a love triangle (including a margin of error) using z = 2 is:

[tex]\implies 78.67\% \pm 9.46\%[/tex]

Note:  It is likely that this question required the critical value to be rounded to the nearest integer, however please note that this is not normal practice as it produces a different result, as evidenced above.

The value of the expression after simplify will be,

''negative 43 over 24 times j plus negative 1 over 12.''

Option D is true.

What is mathematical expression?

Expression in math is defined as the collection of the numbers, variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

The expression is;

''The expression negative one eighth j plus two thirds minus the expression five thirds j plus nine twelfths.''

Now, We can write the expression in mathematical form as;

⇒ (- 1/8  j + 2/3) - (5/3 j + 9/12)

Solve the expression as;

⇒ - 1/8 j + 2/3 - 5/3 j - 9/12

⇒ - 1/8 j - 5/3 j + 2/3 - 9/12

⇒ j (-1/8 - 5/3) + 2/3 - 3/4

⇒ j (- 3 - 40)/24 + (8 - 9)/12

⇒ j (-43/24) + (- 1/12 )

This can be written as;

''negative 43 over 24 times j plus negative 1 over 12''

Therefore, The value of the expression after simplify will be,

''negative 43 over 24 times j plus negative 1 over 12.''

Answer:

As televisions became more affordable and advertisers flocked to the new medium, radio stations had to quickly adapt to the changing field. Stations stopped using live in-studio performances, instead playing less expensive recordings.

Step-by-step explanation:

In the 1950s, television surpassed radio as the most popular broadcast medium, and commercial radio programming shifted to narrower formats of news, talk, sports and music. Religious broadcasters, listener-supported public radio and college stations provide their own distinctive formats.

If  an automatic machine inserts mixed vegetables into a plastic bag.  the probability of selecting four packages that are underweight is: 0.000000390625

Probability can be defined as the tendency or likelihood that an event will happen.

We would be making use of multiplication rule to determine the probabiliy that four packages are underweight.

Given :

Underweight = 2.5 % or 0.025

Hence,

Now let find the probability that  P (all four underweight) :

P(all four underweight) = ( 0.025 ) ( 0.025 ) ( 0.025 ) ( 0.025 )

P(all four underweight) = 0.000000390625

The intervals on which the graph is increasing at (-∞, 0) U (3.5, ∞). On the other hand, the graph is decreasing at (0, 3.5)

A graph can be defined as a pictorial representation or a diagram that represents data or values.

Increased or decreased functions are two categories of functions. Consequently, a function increases when the y-values grow, while a function decreases when the y-values decrease.

The graph indicates the y-values increase in the x-intervals from -∞  to 0 and from 3.5 to ∞. You can express that a function is increasing in the following ways using interval notation:  (-∞, 0) U (3.5, ∞).

In mathematics, the absolute value or modulus of a real number x, denoted |x|, is the non-negative value of x without regard to its sign. Namely, {\displaystyle |x|=x} if x is a positive number, and {\displaystyle |x|=-x} if x is negative, and {\displaystyle |0|=0}.
