Set it up as a ratio:
16 ounces feeds 80, 12 ounces feeds X
16 / 80 = 12 / X
Cross multiply:
16X = 80*12
16X = 960
Divide both sides by 16:
X = 960 / 16
X = 60
12 ounce feeder will feed 60 hummingbirds.
Average rate of change of f(x) from x = 1 to x = 4 represents the average speed with which the water is falling between the first second and the fourth second.
It depends on what the x and y axis are. If the y axis is time and x axis is distance then the bottom line is faster. If the y axis is distance and x axis time then the top line is faster. Whichever line has more distance based on time is faster
Answer:
C=100
Step-by-step explanation:
The margin of error is 1.41.
The margin of error is calculated using the formula
where z is the z-score associated with the confidence level, σ is the standard deviation, and n is the sample size.
For a confidence level of 95%, we find the z-score by first converting the percent to a decimal and subtracting it from 1:
1 - 0.95 = 0.05
Divide that by 2:
0.05/2 = 0.025
This is the area in each tail.
Subtract this from 1 again, since we want the area between the tails:
1 - 0.025 = 0.975
Looking this up in the z-table (http://www.z-table.com) we see that the z-score is 1.96.
Using our information, we have:
