Answer:
1.25$/per quart of oil. 14.05 starting fee.
Step-by-step explanation:
Give a variable that one quart of oil is o.
5o + starting fee +2.5 = 7o + starting fee
2o = 2.5
o = 1.25
substitute and we know starting fee is 14.05
So say you have just 49 raised to the 1/2, that is equivocal to the square root of 49, which is 7. Instead, you have 49 raised to the negative half power, so all you need to do is move that term to the denominator of its fraction. You now have 1/49^(1/2) which turns out to be 1/7
Answer:
C. The statement indicates that the true population percentage of people that prefer chocolate pie is in the interval 11%±3%.
Step-by-step explanation:
Data provided in the questions
Number of respondents = 1,000
Choose chocolate pie = 11%
margin of error = ±3 percentage points
Based on the above information,
The lower limit is
= 0.11 - 0.03
= 0.08
And, the upper limit is
= 0.11 + 0.03
= 0.14
So based on the above computation, the option c is correct as it represents the true population percentage of people with respect to the chocolate pie preference
