It is the exponent.
The exponent is the number used in a power to represent the number of times the base is used as a power.
For example: 7^2. The number 2 is the exponent and it indicates that the number 7 (which is the base) is used two times as a factor, this is, 7^2 = 7 * 7.
Othe example: 4^6. The exponent 6 indicates that the base 4 is used 6 times as a factor => 4^6 = 4 * 4 * 4 * 4 * 4 * 4.
Answer:
3/4, 3:4, 3 to 4
Step-by-step explanation:
Answer:
From this result we can conclude that the value of 70.9 is 0.78 deviation below the true mean of 71.5 and that can be considered as unusual. If we conduct a hypothesis test or a confidence interval we will see that we have enough evidence to conclude that the true mean is not significantly different from 71.5.
Step-by-step explanation:
For this case from all the population we know that the population mean and deviation are:
And we take a random sample of size n =40 and we got a sample mean calculated with the following formula:
And we want to test if this value is unusually low.
Since the sample size is large n>30 we can use the central limit theorem who says that the distribution for the sample mean is given by:
And on this case if we replace the values that we have we got:
For this case we can calculate how many deviations above or below is our calculated value from the sample of size 40, using the z score given by:
From this result we can conclude that the value of 70.9 is 0.78 deviation below the true mean of 71.5 and that can be considered as unusual. If we conduct a hypothesis test or a confidence interval we will see that we have enough evidence to conclude that the true mean is not significantly different from 71.5.
Answer:
Below :)
Step-by-step explanation:
The difference of the means would be:
90 - 50 = 40
When finding difference you need to use subtraction.
The difference is 40
The MAD score is 10
"This difference is 4 times the value of the MAD of each data set."
Answer:
it is B because if you divide by fractions by the ratio of 3 people you get (B) $90.00
