17∠x-11 set up the equation like this
28∠x add 17 to the other side, and you get x is greater than 28

Answer:
Our score = 0.60, Amanda's score = 0.25
Step-by-step explanation:
For Amanda
μ = 15 , σ = 4
z- score for X = 16 is (From z table)
z = (X - μ)/σ = (16 - 15)/4 = 0.25
For us
μ = 310 , σ = 25
z score for X = 325 (From z table)
z = (325-310)/25 = 0.60
Since our z score is better than Amanda's z score, we can say we did better
False ......................................
x*x=152
x2=152
Take square root.
x=±√152
x=√238
or
x=−√238
