Step-by-step explanation:
It’s the only one with a data point very far from the rest
Answer:
c 70
Step-by-step explanation:
supplementary means they equal 180
180 - 110 = 70
Answer:
The answer is E. Impossible to determine
Step-by-step explanation:
Normally, you would find the Confidence interval of a normal sample by using
X(-+) Z* Sigma/n
Where x is the mean, sigma the standard deviation n the size of the sample and z the value determined by your confidence interval size of 95%
.However, this approximation of a confidence interval may only be used for a sample if the number of observations is at least 30 or above. When we have less observations than 30 we must use the standard deviation of the populations. But we only have a sample standard deviation so its not adequate or possible to determine CI the true mean of the population with such a small sample size.
Parallelogram A: height = 5
parallelogram B: base = x-3
parallelogram C: height = 2x+y
Given:
The vertices of a polygon are A (−1, 1), B (4, 1), C (4,−2), and D(−1,−2).
To find:
The perimeter of ABCD.
Solution:
Distance formula:
Using distance formula, we get
Similarly,
Now, perimeter of ABCD is
Therefore, the perimeter of ABCD is 16 units.
