Arelative frequency table is made from data in a frequency table. relative frequency table: a 4-column table with 3 rows. the first column has no label with entries likes e, f, total. the second column is labeled g with entries y, 31%, 58%. the third column is labeled h with entries 24%, 18%, 42%. the fourth column is labeled total with entries 51%, 49%, 100%. what is the value of y in the relative frequency table? round the answer to the nearest percent. 12% 27% 46% 52%

Jeffery conducted a survey in his school and found that 30 of the 50 eighth grade students' favorite subject is mathematics. based on the results, jeffery concluded that out of the 200 students in his school, 120 students' favorite subject is mathematics. select the statement that is true about jeffery's conclusion. a. jeffery's conclusion is not valid because the sample was biased since only 200 students were surveyed. b. jeffery's conclusion is valid because the sample was random since all of the students were eighth grade students. c. jeffery's conclusion is valid because the sample was random. d. jeffery's conclusion is not valid because the sample was biased since all of the students were eighth grade students.

For the equations below which statement is true ? -2x=14 6x=-42

Me solve this problem, and someone clearly explain to me how to solve it.1.) use the value of the discriminant to determine if the given trinomials has 2 real solutions, 1 real solution, or no real solutions. a.  x2  − 4x  − 7 = 0b. 4r2  + 11r  − 3 = 0c. 3m2  + 7 = 0d.  t2  + 2t  + 1 = 0
