Answer:
Following are the solution to the given points:
Step-by-step explanation:
For point (a)
:
In this, two points are exclusive to one another, it is a probability that first or the second project will have breaches,
Since the p(A & B)=0 is mutually exclusive.
For point (b):
For point (c):
if both a and b are independent:
(a):
(b):
Answer:
55 1/2 feet
Step-by-step explanation:
.25 yards = 9 inches
9 inches x 74 bookmarks= 666 inches
12 inches = 1 foot
666 inches/12 inches = 55.5 feet
-0.83 would be the strongest out of these options.
It's negative, so we know it'd going down, and it's also much stronger than -0.23.
The area of the triangle ABC is 81. 33 square units.
We have to determine
What is the area of triangle ABC?
<h3>
What is the formula for the area of a triangle?</h3>
The area of the triangle is determined by;
Where the value of s is = a + b + c= 12 + 14 + 16 = 42
Substitute all the values in the formula;
Hence, the area of the triangle ABC is 81. 33 square units.
