Answer: 0.701
Step-by-step explanation:
Formula : , where
significance level ,
Population standard deviation, n= sample size.
As per given, n= 22
Critical z- value for 90% confidence level :
Then,
Hence , error bound (EBM) of the confidence interval with a 90% confidence level= ± 0.701
The slope-intercept form:
m - slope
b - y-intercept → (0, b)
We have the point (0, 5). Therefore b = 5.
We have: y = mx + 5
Other point (3, 2). Substitute the coordinates of the point to the equation of the line:
<em>subtract 5 from both sides</em>
<em>divide both sides by 3</em>
Answer:
The area is:
Step-by-step explanation:
Area of this figure is simply the product of the base and the height, as it just happens to be a slanted or inclined rectangle.
Therefore:
