200-20+40
The 16 isn’t in the equation because they are coming back.
So your answer is 220.
Divide each by 5 , now it is 7 over 9
Answer: The cost per person would be $15.20.
Step-by-step explanation: The price $40 per person when you have 5 people, is 8,8x the price per person. So, if you have 6 people more, you have 8,8x6 less in the price.
8,8 x 6 = 52,80.
44 x 5= 220,00. That was the cost for the limo for 5 people.
It means 220,00 - 52,80 = 167,20 (new price for 11 people)
167,20 ÷ 11 (new price per person) = 15,20.
Answer:
(0.0706, 0.1294)
Step-by-step explanation:
Confidence interval of a proportion is:
CI = p ± CV × SE
where p is the proportion,
CV is the critical value (z score or t score),
and SE is the standard error.
The sample is large enough to estimate as normal. For 95% confidence level, CV = z = 1.96.
Standard error for a proportion is:
SE = √(pq/n)
SE = √(0.1 × 0.9 / 400)
SE = 0.015
The confidence interval is:
CI = 0.1 ± (1.96)(0.015)
CI = (0.0706, 0.1294)
Round as needed.
