Answer:
i think it is c
Step-by-step explanation:
1. If x=6, 6+37=?46 43≠46. It isn’t a solution.
2. If x=12, 12+37=?46 49≠46. it’s not a solution.
3. If x=9, 9+37=?46. 46=46. It’s a solution!
4. If x=83, 83+37=?46. 120≠46. Not a solution.
Only x=9 Is a solution.
Hope it helps!
Yes, it has infinetly many solutions
The z-score is given by:
z=(x-mean)/s.d
the z-score giving us P(0.95)=1.96 and -1.96
thus;
-1.96=(x-1500)/300
-588=x-1500
x=-588+1500
x=912
also:
1.96=(x-1500)/300
588=x-1500
x=588+1500
x=2,088
therefore the sample size of the student picked will be given by:
2,088-912
=1,176
