Answer:
Step-by-step explanation:
a-number of advance tickets
s-number of same day tickets
a*40+s*25=2400
a +s =75
I solve with the substitution method
s=75-a
40a+25*(75-a)=2400
40a+1875-25a=2400
15a=2400-1875
15a=525
a=525/15
a=35
so s=75-35
s=40
Answer:
Step-by-step explanation:
P = $ 500 ;r =8% ; n= 8
A = P* (1+r/100)^n
A= 500 * ( 1 + 8/100)⁸
= 500 * ( 1 + 0.08)⁸ = 500 * 1.08⁸
=500*1.85
= $ 925.45
Answer:
0.22
Step-by-step explanation:
The point estimate is simply the middle of the confidence interval.
p = (0.195 + 0.245) / 2
p = 0.22
