It takes 3 minutes to fill 60L, so it takes 1 hour to fill 1200L.
Answer:
When sampling from a population, the sample mean will: be closer to the population mean as the sample size increases.
Step-by-step explanation:
The sample mean is not always equal to the population mean but if we increase the number of samples then the mean of the sample would become more and more closer to the population mean.
Usually the population size is very huge that is why we select a random sample from the population, care must be taken to ensure randomized sampling otherwise results would not be accurate. After that we have to make sure that the number of samples are enough for the given population size. The number of samples depends upon the shape of the population. If the population is normal than according to central limit theorem, a less number of samples would be enough to ensure normal distribution of sampling mean, otherwise a greater sample size will be required.
Answer:
√85
Step-by-step explanation:
for this, you will probably need to draw a graph. Plot the points, and then you will notice that you can draw a triangle with one side being the x-axis ( go on to (-6,0) then drop down unitll you hit the point (-6;-7)
// use the pythagoream theorem to find the length
the distance of the leg on the x-axis is 6 (calculate 0-(-6))
the distance of the leg that is dropping down is -7 (calculate 0-(-7))
then we have 2 legs and need to find the hypotenuse.
Pythagorean theorem a^2 + b^2 = c^2
substitute :
6^2 + 7^2 = c^2
36+49 = 85
c= √85
Answer:
Option C. 356 gidgets
Step-by-step explanation:
we have R(x) ----> the monthly revenue function C(x) ---> the monthly cost function x ----> the number of gidgets sold we know that Break-even means that the revenue equals cost so solve for x
You want to isolate the y variable so subtract 3x from both sides to get -6y = 9 - 3x
next divide the equation by -6 to get
y = 9 + 3/-6x
change to slope-int form (y = mx + b)
y = -3/6x + 9
