Freshmen and sophomores were asked about their preferences for an end-of-year field trip for students who pass their final examinations. Students were given the choice to visit an amusement park, a water park, or a mystery destination. A random sample of 100 freshmen and sophomores was selected. The activities coordinator constructed a frequency table to analyze the data. Students’ Field Trip Preferences

Amusement Park Water Park Mystery Destination Total
Freshman 25 10 20 55
Sophomores 35 5 5 45
Total 60 15 25 100

Part A: What does the relative frequency LaTeX: \frac{10}{55}10 55 represent?

687.09 dollars       happy now

step-by-step explanation: 6870

1857 times .63 equals 1169.91 subtract that from 1857 you get 687.09

the number of the people going.

step-by-step explanation:

the cost to buy one movie ticket is $7. if the total cost for the movie is a function of how many people go, then the input is : the number of the people going.

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.
