Answer:
Step-by-step explanation:
The mode in statistics is the number that occurs the most in a data set.
So you basically have to find the set that has the most threes.
A and C both have 3 threes. I think there might be another 3 in one of those if there has to be only one answer.
So the answer can be either A or C.
Hope this helps!
Answer:
width = 7 cm
Step-by-step explanation:
63 / 9 = 7
Therefore, 7 * 9 = 63cm cube
Answer:
The difference between the size of white blood cells and the size of red blood cells in scientific notation is m.
Step-by-step explanation:
we are given that the size of white blood cells is 0.000012 metres and the size of red blood cells is 0.0000065 metres.
And we have to find the difference between the size of both cells in scientific notation.
SO, Size of White blood cells = 0.000012 m
Size of Red blood cells = 0.0000065 m
Now, Difference between both cell sizes = Size of white blood cells - Size of Red blood cells
= 0.000012 m - 0.0000065 m
= 0.0000055 m
Now, in scientific notation it is represented as = m
Hence, the difference between the size of white blood cells and the size of red blood cells in scientific notation is m.

Answer:
A company produces electric insulators. The strength of the insulators is important since a broken insulator may cause a short circuit. Unfortunately, the strength varies significantly due to the material. Because of the expense, only a limited number of insulators could be tested. The engineers sampled 25 insulators (From a production run of 200), and conducted a destructive test to determine the force that was required to break the insulators. The mean value of this force was 1723 lbf with a sample standard deviation of 90 lbf. You may approximate the population standard deviation with the sample standard deviation for the following questions. a. Determine if the population is large enough or if a finite population correction (FPC) factor is needed. If so, what is the FPC factor? b. For 95% confidence, determine the margin of error (+ lbf) c. For these conditions, estimate the range of the probable population mean. Provide lower and upper values. For 95% confidence, determine the margin of error ( Assume the same mean and sample standard deviation. What is one advantage and one disadvantage of using 50 insulators instead of 25 insulators? d. lbf) if 50 insulators were tested.
