Ernie's favorite movie of the year is now in its fourth week in the theaters. He is gathering data about its earnings each week. He is also interested in knowing how other recently released movies are doing at the box office compared with his favorite movie. The table gives the earnings of the top-five movies during the third week that Ernie’s favorite movie, movie A, was showing in theaters. Movie Earnings Average Ticket Price A $26,088,808.74 $8.35 B $60,394,938.12 $9.72 C $23,659,617.52 $8.12 D $34,311,887.98 $7.57 E $10,505,611.08 $8.46

Answers

Final answer:

To compare the relative success of his favorite movie to others, the student can calculate each movie's ticket sales by dividing its total earnings by the average ticket price. This provides a clearer idea of the viewership each movie had, which can be more informative than simple box office earnings.

Explanation:

The student is interested in the earnings of his favorite movie in relation to other recently released films. To compare these films, one could calculate each movie's ticket sales by dividing its earnings by the average ticket price. For instance, the ticket sales for the movie A would be calculated by dividing its earnings, $26,088,808.74, by its average ticket price, $8.35. This calculation would need to be repeated for each movie to have a clear comparison.

These calculations will help Ernie understand how many people, roughly, saw each movie, since box office earnings alone can be skewed by differing ticket prices. In other words, a movie could have higher earnings than another but still have fewer viewers if its tickets were significantly more expensive.

Which second-degree polynomial function has a leading coefficient of –1 and root 5 with multiplicity 2?

Answers

A second degree polynomial function has the general form:

                  [tex]\displaystyle{f(x)=ax^2+bx+c[/tex], where [tex]a\neq0[/tex].

The leading coefficient is a, so we have a=-1.

5 is a double root means that :

i) f(5)=0,
ii) the discriminant D is 0, where [tex]D=b^2-4ac[/tex].

Substituting x=5, we have

                                        f(5)=a(5)^2+b(5)+c,

and since f(5)=0, and a is -1 we have:

                                          0=-25+5b+c
thus c=25-5b.


By ii) [tex]\displaystyle{b^2-4ac=0[/tex].

Substituting a with -1 and c with 25-5b we have:
                                     
          [tex]\displaystyle{b^2-4ac=0[/tex]
          [tex]\displaystyle{b^2-4(-1)(25-5b)=0[/tex]
          [tex]\displaystyle{b^2+4(25-5b)=0[/tex]
          [tex]\displaystyle{b^2-20b+100=0[/tex]
          [tex]\displaystyle{(b-10)^2=0[/tex]
          [tex]\displaystyle{b=10[/tex] 


Finally we find c: c=25-5b=25-50=-25

Thus the function is        [tex]\displaystyle{f(x)=-x^2+10x-25[/tex]


Remark: It is also possible to solve the problem by considering the form

[tex]f(x)=-1(x-5)^2[/tex] directly.

In general, if a quadratic function has leading coefficient a, and has a root r of multiplicity 2, then its form is [tex]f(x)=a(x-r)^2[/tex]

The scores on ms. martin's statistics quiz had a mean of 12 and a standard deviation of 3. ms. martin wants to transform the scores to have a mean of 75 and a standard deviation of 12. what transformations should she apply to each test score? explain.

Answers

Final answer:

To transform the scores to have a mean of 75 and a standard deviation of 12, Ms. Martin needs to subtract the current mean from each test score, divide the result by the current standard deviation, multiply the result by the new standard deviation, and add the new mean to each transformed score.

Explanation:

To transform the scores to have a mean of 75 and a standard deviation of 12, Ms. Martin needs to apply two transformations to each test score:

First, she needs to subtract the current mean of 12 from each test score.Then, she needs to divide the result by the current standard deviation of 3.After applying these transformations to all the scores, she needs to multiply each result by the new standard deviation of 12 and finally add the new mean of 75 to each transformed score.

By following these steps, Ms. Martin will successfully transform the scores to have the desired mean and standard deviation.

First, rewrite 9/10 and 23/25 so that they have a common denominator.

Then, use
<, =, or > to order 9/10 and 23/25

Answers

the cheap answer is, well, all we do is, grab the denominator of one and multiply the other by it, top and bottom, and grab the denominator of the other, and multiply the first one by that one too, that way, both will have the same denominator, and then you can simply check the numerator to see who's larger, let's do so.

[tex]\bf \cfrac{9}{\boxed{10}}\qquad \qquad \cfrac{23}{\boxed{25}} \\\\\\ \cfrac{9\cdot \boxed{25}}{10\cdot \boxed{25}}\implies \cfrac{225}{250}\qquad \qquad \qquad \cfrac{23\boxed{10}}{25\cdot \boxed{10}}\implies \cfrac{230}{250}\\\\ -------------------------------\\\\ \textit{so, which is larger then?}\qquad \cfrac{225}{250}~or~\cfrac{230}{250}?[/tex]

surely you can tell.
The lowest common multiple of 10 and 25 is 50, so set that as the denominator.

9/10=45/50 (multiply by 5)
23/25=46/50 (multiply by 2)

46/50 > 45/50 therefore
23/25 > 9/10.

What is the sum of the first eight terms of a geometric series whose first term is 3 and whose common ratio is 1/2?

Answers

The answer to this question What is the sum of the first eight terms of a geometric series whose first term is 3 and whose common ratio is 1/2 is (7/65/128)

Answer:

[tex]\frac{765}{128}[/tex]

Step-by-step explanation:

We have been given that 1st term of a geometric series is 3 and common difference is 1/2 . We are asked to find the sum of 1st 8 terms of the given series.

We will use geometric series formula to solve our given problem.

[tex]S_n=\frac{a_1(1-r^n)}{1-r}[/tex]

Upon substituting our given values in the above formula we will get,

[tex]S_8=\frac{3(1-(\frac{1}{2})^8)}{1-\frac{1}{2}}[/tex]

[tex]S_8=\frac{3(1-\frac{1^8}{2}^8)}{\frac{2-1}{2}}[/tex]

[tex]S_8=\frac{3(1-\frac{1}{256})}{\frac{1}{2}}[/tex]

[tex]S_8=\frac{3(\frac{256-1}{256})}{\frac{1}{2}}[/tex]

[tex]S_8=\frac{3(\frac{255}{256})}{\frac{1}{2}}[/tex]

[tex]S_8=3(\frac{255}{256}\times\frac{2}{1})[/tex]

[tex]S_8=3(\frac{255}{128})[/tex]

[tex]S_8=\frac{765}{128}[/tex]

Therefore, the sum of our given series is [tex]\frac{765}{128}[/tex].

store decreased its price on a computer by $112 to $478. What was the original price

Answers

Well if it's $112 less and the price is now $478. You just have to add $112 to $478= $590.

Answer:

$590.

Step-by-step explanation:

Let x be the original price of computer.

We have been given that a store decreased its price on a computer by $112 to $478.

This means x minus 112 equals to 478. We can represent this information in an equation as:

[tex]x-\$112=\$478[/tex]

Let us add $112 to both sides of our equation.

[tex]x-\$112+\$112=\$478+\$112[/tex]

[tex]x=\$590[/tex]

Therefore, the original price of computer was $590.
