Step-by-step explanation:
SA formula: 2Lw + 2Lh + 2hw
for this box: 2(4×10)+2(10×16)+2(4×16)
2(40)+2(160)+2(64)
80+320+128

Answer:
Yes, we can expect the given result
Step-by-step explanation:
The population proportion P = 0.60
the 95% confidence interval is ( 0.56, 0.76)
The 95% confidence that the true population proportion lies between the interval ( 0.56, 0.76)
Only 5% of 20 random samples i.e only 1 sample is not contain in the population proportion.
Step-by-step explanation:
2x²+3x-2=0
(2x-1)(x+2)
x+2=0
x=-2 (no, because x must be >0)
2x-1=0
2x=1
x=½ (yes, because x>0)
