Answer:
Which expressions is equivalent to 4/5*120= 96
B 4*120 divided by 5=96
Step-by-step explanation:
The second question is 589 4/5
(5*100)+(8*10)+(9*1)+(2*1/10)+(6*1/100)= 589 4/5
Answer: The margin of error = 3.71, confidence interval = (354.04, 361.46) and it means that mean cost is lies within the confidence interval.
Step-by-step explanation:
Since we have given that
Sample size = 400
Mean = $357.75
Standard deviation = $37.89
At 95% confidence level, z = 1.96
We first find the margin of error.
Margin of error is given by

95% confidence interval would be

Hence, the margin of error = 3.71, confidence interval = (354.04, 361.46) and it means that mean cost is lies within the confidence interval.
5.6 because 7=1=8 so 8-2.4=5.6
