Answer:
15,2% of American men are between 68.6 and 69.4 inches tall.
Step-by-step explanation:
p(69)=0.19 tells you that 19% of all American men are 69in tall. Now, we want to know what percentage of those men are exactly between 68.6 and 69.4 inches tall. We only need to multiply the given density function by the gap between the two heights we are looking for, so:
0.19 * (69.4-68.6) = 0.19*0.8 = 0.152*100 = 15,2%

Answer:

Step-by-step explanation:
The distance between two coordinates is given by:
, or
.
The distance between each of the coordinates of the triangle forms the sides of triangle. Therefore, we can add the distance between these coordinates to find the perimeter of the triangle.
The distance between
and
is:

The distance between
and
is:

.
Therefore, the total perimeter of the triangle is:
.
