Add up the number of students within the random sample data:
32+26+28+22 = 108

We can then use proportional fractions / cross-multiply to answer the question.

In a sample size of 108 students, 32 of them preferred Movie A.
There are 900 students in total.

\frac{32}{108} =\frac{x}{900}

32*900 = 28800

108*x = 108x

108x = 28800

x = 266\frac{2}{3} or \frac{800}{3}

In decimal form that is approximately 266.667 and round that to the nearest whole number, you get 267 students who would prefer Movie A.

3/2=4/3x+2/3 What does X equal?
Anna71 [15]

Answer:

x = 30/48 or x = 0.625

Step-by-step explanation:

3/2 = 4/3x + 2/3

Convert to common denominator

9/6 = 8/6x + 4/6

subtract 4/6 from both sides

9/6 - 4/6 = 8/6x + 4/6 - 4/6

5/6 = 8/6x

Divide by 8/6

5/6 x 6/8 = x

30/48 = x

x = 30/48

If my answer is incorrect, pls correct me!

Ft (full time)= $2,400/ monthpt (part time)= $200/ week15% taken from taxes------------------------- 1 year= 12 months; 1 month= 4 weeks (12*2,400) + (4*12*200)= $38,400 you made in a year I set up the problem this way because you want to know how much you made that whole year, so if there are 12 months in a year, and you get paid $2,400 a month, then from your full time job you ear (12*2,400). From your PT job you make $200 a week, there are 4 weeks in a month and 12 months in a year, so to calculate what you earned from your PT job, you do: 4*12*200 15% of what you made is deducted from taxes:0.15(38,400)= $5,760 After taxes, you made:$38,400-$5760= $32,640
