Answer:
The measure of the shortest side is 851 miles
Step-by-step explanation:
Let
x ----> the measure of the shortest side
y ---> the measure of the middle side
z ---> the measure of the longest side
we know that
The perimeter of triangle is equal to
so
----> equation A
the shortest side measures 71 mi less than the middle side
so
----> equation B
the longest side measures 372 mi more the the middle side
so
----> equation C
substitute equation B and equation C in equation A
solve for y
Find the value of x
therefore
The measure of the shortest side is 851 miles
This is a guess. But over 3000 dollars saved up
Answer:
?
Step-by-step explanation:
There are 45C4 = 148,995 ways to choose 4 calculators out of a group of 45.
There are 33C4 = 40,920 ways to choose 4 calculators that are not defective.
The probability that at least one is defective is (148,995 -40,920)/148,995 ≈ 0.725.
