Step-by-step explanation:
The ratio of the two shorter legs of the top triangle is
The bottom triangle has the following ratio:
Since their ratios are the same, this means that the two triangles are similar.
Step-by-step explanation:
a. The point estimate is the mean, 47 days.
b. The margin of error is the critical value times the standard error.
At 31 degrees of freedom and 98% confidence, t = 2.453.
The margin of error is therefore:
MoE = 2.453 × 10.2 / √32
MoE = 4.42
c. The confidence interval is:
CI = 47 ± 4.42
CI = (42.58, 51.42)
d. We can conclude with 98% confidence that the true mean is between 42.58 days and 51.42 days.
e. We can reduce the margin of error by either increasing the sample size, or using a lower confidence level.
The inver of given function will be (1,-3).
The number of full periods and classes does a 202-digit number have are 1 and 3 respectively.
<h3>What are periods?</h3>
Periods are simply groups of three digits separated by commas when writing numbers in standard form.
The digit number, 202 has 1 period.
Classes is simply the number of digits in a set.
Example: 500 has 3 classes
We can say that the 202 digit number has 1 period and three classes.
Thus, the number of full periods and classes does a 202-digit number have are 1 and 3 respectively.
