Out of a population of 1,000 students, 80 were asked by a random sampling what color they would prefer for their first car. their responses are shown in the table below. car color favorite color number of students blue 5 red 18 gray 27 silver 14 white 16 using proportional reasoning, how many students out of the 1,000 would you expect to prefer a silver car? students

175 students

Step-by-step explanation:

With a random sample of 80 students, 14 of them prefer a silver car . If you change to 1000 students the proportion is the next one:

(student who prefer a silver car)/(total of students) =  14/80 = x/1000

Isolating x:

x = (14/80)*1000 =  175

175 hope I helped

Step-by-step explanation:

38.5

step-by-step explanation:

lets say, first number = r

second number = 3r+7

total = 49

(r)+(3r+7)= 49

4r+7 = 49

4r = 42

r = 42/4

r= 10.5

3r+7 = 3(10.5)+7 = 38.5

hope this
