A is the answer because it is the widest variety
Answer:
d. We are 95% confident that the proportion of adults (ages 17-26) who attended college is between 53% and 59%.
Step-by-step explanation:
Confidence interval of a proportion p.
We build a confidence interval at the x% level from a sample.
With this, we can say that we are x% sure that the true population propotion is in the interval.
The 95% confidence interval is (0.53, 0.59).
This means that we are 95% sure that the true population proportion is between 0.53 and 0.59.
So the correct answer is:
d. We are 95% confident that the proportion of adults (ages 17-26) who attended college is between 53% and 59%.
Answer:
x ≈ 57.8°
Step-by-step explanation:
using the Sine rule in the triangle
= 
( cross- multiply )
8 × sinx = 11 × sin38° ( divide both sides by 8 )
sinx = 
, then
x = 
( ) ≈ 57.8° ( to 1 dec. place )
Answer:
Approximately 201 squared inches.
Step-by-step explanation:
So, the composite figure is made up of a square and a semi-circle. The square has side lengths of 12 and the semi-circle has a radius of 6.
The total area of the figure would be the area of the square plus the area of the semi-circle. Thus, find the area of each individual figure.
Square:
The area of a square is given by:
Where l is the side length.
Substitute 12 for l:
So the square is 144 square inches.
Semi-circle:
The area of a semi-circle is given by:
Substitute 6 for r and 3.14 for π:
Therefore, the total area is:
<span>The durations and coverage of the manufacturer’s warranty, as well as whether or not the extended warranty overlaps with it, should be taken into consideration. The likelihood of the item needing repairs, as well as the cost of repairing it, should also be considered. Furthermore, it is helpful to consider the cost of the warranty, its relation to the cost of the item, and whether it is a full or limited warranty.
