Answer:
12.5% failed
Step-by-step explanation:
Convert the fraction 10 out of 80 into a decimal to become the percentage
The asymptotes are Y=2 and X=2, -2
Answer:
arithmetic series
Step-by-step explanation:
We are adding 1 each time , so this is an arithmetic sequence
a1 =5
The common difference is 1 so d=1
an = a1+d(n-1)
an = 5 + 1(n-1)
an = 5+n-1
an = n+4
If we have an arithmetic sequence, we have an arithmetic series when we add the arithmetic sequence
It is true that the confidence intervals for the mean provide an estimate for where the true mean lies.
In statistics, a confidence interval denotes the likelihood that a population parameter will fall between a set of values for a given proportion of the time. A confidence interval depicts the likelihood that a parameter will fall between two values near the mean. Confidence intervals quantify the degree of uncertainty or certainty in a sampling procedure.
The mean is a basic mathematical average of two or more values. There are two sorts of means that may be calculated: the arithmetic mean and the geometric mean. A mean tells you the average of a bunch of values, which helps you contextualize each data point.
