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
Answer:
answer is below
Step-by-step explanation:
tan p = 32/24 = 4/3
tan q= 24/32 = 3/4
Well, it would end up to 3x=14 which is x=4.33
3-(-5) 8 4
——— = —- = —-
3-(-3). 6 3
Answer:
mixed
