For question 4 it will be 416.666666667 so to make it easier you can just put "They have to provide about 416.67 pound of food each day"
Answer: A) y = 6x
Step-by-step explanation:
That is true. Let's say there are 100 fish. If half the fish are zebra danios then there are 50 zebra danios fish. If there are 50 fish left, and there are 2 times as many catfish as there are fancy guppies, then 33.33 of them are catfish and 16.66 of them are fancy guppies. Since one third of 100 is 33.33, then 1/3 of the fish are catfish.
Answer:
Population mean = 21
Margin of error = 4
Step-by-step explanation:
Given that
Lower bound of the population is 17
Upper bound of the same population is 25
The population mean, x-bar is calculated by saying
x-bar = (lower bound + upper bound)/2
x-bar = (17 + 25)/2
x-bar = 42/2
x-bar = 21
Margin of error for the confidence interval is gotten by
E = (upper bound - lower bound)/2
E = (25 - 17)/2
E = 8/2
E = 4
Thus, the mean is 21, while the error is 4
