A class at Middlebury school collected date on the types of movies students prefer. Complete each statement using the table.
likoan [24]

Based on the information of the table, you have:

1. The ratio is 105/150. By simplifying you get for the ratio 7/10.

2. The students that prefer action movies are 75+90 = 165 and the total numbe of students is 180+240 = 420. Then, the fraction of students who prefer action movies is:

165/420 = 11/28

3. The fraction of seventh graders students that prefer action movies is:

75/180 = 5/12

4. The percent of student that prefer comedy is:

105 + 150 = 255 total student that prefer comedy

420 total number of students

the fraction is:

(x/100)420 = 255

solve for x:

x = 255(100/420)

x = 60.71

the percent of students is 60.71%

5. The percent of eighth graders student who prefer action moveis is:

(x/100)240 = 90

x = 90(100/240)

x = 37.5

the percent of students is 37.5%

6. To determine which from the given grades has the greatest percent of student that prefer action movies, calculate the percent of student in seventh-grade:

(x/100)180 = 75

x = 75(100/180)

x = 41.66

the percent of student is 41.66%

then, seventh grade has the greatest percent of student that prefer action movies.

Solve this quadratic equation using the quadratic formula.<br><br> x2 + 8x - 5 = 0
jasenka [17]
X^2 + 8x - 5 = 0
a = 1, b = 8, c = -5
x = ( - 8 + - sqrt(64 - 4*1*-5))/2
x = ( -8 + - sqrt(64+20))/2
x = ( -8 + - sqrt (84))/2
x = ( - 8 + - 2sqrt21))/2
x = -4 + - sqrt21

calculate E, the amount of euros that has the same value as D U.S. dollars, using the equation E=17/20D=
Aleksandr [31]

<em>The given equation is:  E=17/20 D  , where  E=amount of Euros and D= amount of U.S dollar. </em>

<em> </em>

<em>Now for 1 U.S dollar, we need to plug D=1 into the above equation. So, we will get......... </em>

<em> E=17/20(1)</em>

<em>E=1/20=0.85</em>

<em>0.85 Euros have the same amount as 1 U.S dollar. </em>

<em> </em>
