Christian randomly select students from his grade to read a masters as easy moderate or difficult of the students he surveyed 13 said the test was easy 11 read it as moderate three found it difficult assuming that all students took the same test how many of the 162 total students and christians grade would probably read the test something other than easy a. 27 b.78 c.84 d.126

C. 84.

Step-by-step explanation:

27 students in his grade took the test. 14 did not find it easy. 14/27 is 0.52. 0.52 times the 162 total students is 84.

constant of proportionality = 3 and the equation is c = 3p.

step-by-step explanation:

c = kp   where c = amount of caffeine in mg., p = oz of pepsi and k is the constant of proportionality.

substituting the values given:

24 = 8k

k = 3.

the same value of k will be obtained if we substitute the other given values.

2+2 obliviously is 4.
