The sum (addition) of t and 2 is equal to (=) 5 less than (subtraction) t
2 + t = t - 5
A / b + c
17.0079 / 2.05 + 3.1415926 =
8.29653658537 + 3.1415926 =

Answer:
102 students
Step-by-step explanation:
Note that 65% and 71% are both 1 standard deviation from the mean (71%). According to the empirical rule, 68% of scores lie within 1 std. dev. of the mean.
68% of 150 students would be 0.68(150 students) = 102 students
