I think c but I’m not sure so if I were you I’d wait for someone else to answer
Answer:
$15600
Step-by-step explanation:
Minimum number of samples can be calculated using the formula:
N≥ where
- N is the sample size
- z is the corresponding z-score for 95% confidence level (1.96)
- s is the standard deviation of the calorie consumption (450 cal.)
- ME is the margin of error that the researcher is willing to accept. (50 cal)
N≥ =311.2
Therefore, minimum required sample size for 50 cal standard error in 95% confidence is 312
Since the survey costs $50 for each person then the survey costs minimum
50*312=$15600
Answer:
The constant of proportionality is 1.89
Step-by-step explanation:
2 pounds = $3.78
1 pound = $3.78/2 = $1.89
Cost y is directly proportional to the pound of potato
y = 1.89x
The constant of proportionality is the cost of 1 pound of potato, and it is 1.89
The perimeter is found by adding all the sides together. 2.5+3.25+5 = 10.75 or 10 3/4 inches, choice B
