(0.0974, 0.1226)
Step-by-step explanation:
We first find the sample proportion;
255/ 2373
0.11
The Z value for a 95% confidence interval is 1.960
Therefore;
0.11 +- 1.96 * √ (0.11(1 – 0.11))/2373
0.11 +- 1.96 * 0.00642
0.11 +- 0.0126
= 0.1226
= 0.0974
(0.0974, 0.1226)

Step-by-step explanation:
he has to give away $14 (-14)
and also $7 (-7)
The others have positive numbers.
Explanation:
A triangle can be formed for b=3 and B=15° as long as side c is between 3 and 3/sin(15°) ≈ 11.59 inches in length. The limit for side c on the high end is that it is opposite a right angle. The limit for side c on the other end is that it is opposite a linear angle.
For the given length of side c, there are two possible triangles with b=3 and B=15°. (See attached.)
_____
For the given values of b and c, the largest possible value of B is the angle that puts side c opposite a right angle: B ≤ arcsin(3/7) ≈ 25.3769°
Answer:
When you have intersecting segments such as these, the relationship is that the product of the segment pieces of one segment is equal to the product of the segment pieces of the other. You can use this relationship to help you solve problems that ask you find the length of a missing segment piece.
