Answer:
The correct option is;
B. With 95 percent confidence, it can be said that the repair cost is between the bounds of the confidence interval
Step-by-step explanation:
Here we have the formula for confidence interval, CI given as follows;
Where:
= Sample mean = $90.00
s = Sample standard deviation = $14.00
n = Sample size = 5
t = z value for the confidence level = 2.7764 from z-score relations
Plugging in the values, we have;
Which gives the CI as 72.6167 to 107.38.

Answer:
The similarity statement that expresses the relationship with the two triangles is that "Triangle P Q R is similar to Triangle W X Y"
Step-by-step explanation:
In drawing and labeling triangles, the three angles are labeled with letters that follow alphabetically. Thus, a triangle A B C should be in similarity with triangle x y z. Like wise from the above statements, triangle P R Q can only be similar in labeling in the range of W X Y even if the figures are not shown.
Answer: -4/5, in decimal form -0.8
Step-by-step explanation: −4.1+2n+1+0.3n
Combine Like Terms:
=−4.1+2n+1+0.3n
=(2n+0.3n)+(−4.1+1)
=2.3n+−3.1
=2.3n−3.1
