The answer is 3.71%
Given: .62 probability of reaching 75 years old and 0.023 probability of reaching 85 years old
Since Mr. Clooney already reached 75 years old, we'll divide the probability of reaching 85 by the probability of reaching 75.
<span>.023 / .62 = .0370967742 x 100 = 3.71%
Why? </span><span>Assume there are 1000 men who were born at the same time.
0.62 * 1000 = 620 of them will make it to 75.
0.023 * 1000 = 23 of them will make it to 85.
The proportion of those who will make it to 85 assuming that they already made it to 75 will be 23 / 620 = 0.0370967742 (same as above)</span>
Hey, there isn't a question, but I'd love to help!
Answer:
The answers are (8,48) and (13,78)
Step-by-step explanation:
t=x-axis or x
r=y-axis or y
52=6(9) → 52≠54 not correct
48=6(8)→48=48 correct
74=6(12)→74≠72 not correct
78=6(13)→78=78 correct
44=6(7)→44≠42 not correct
X + k y = 1
k x + y = 1 / * ( - k )
----------------
x + k y = 1
- k² x - k y = - k
--------------------
x - k² x = 1 - k
x ( 1 - k² ) = 1 - k
x = ( 1 - k ) / ( 1 - k² ) = ( 1 - k ) / ( 1 - k ) ( 1 + k )
y = 1 - k( 1 - k )/( 1 - k² )
y = ( 1 - k ) / ( 1 - k² ) = ( 1 - k ) / ( 1 - k ) ( 1 + k )
a ) For k = - 1 this system has no solution.
b ) For k ≠ - 1 and k ≠ 1, the system has unique solution:
( x , y ) = ( 1/ (1 + k) , 1/( 1 + k ) ).
c ) For k = 1, there are infinitely many solutions.

Answer:
625 square feet
Step-by-step explanation:
The greatest area of a polygon with a given perimeter is that of a regular polygon. A regular rectangle is one that has all sides the same length -- a square. The side length of a square with 100 ft perimeter is 25 ft. The area of a square with such a side length is
A = (25 ft)² = 625 ft²
The maximum possible area is 625 ft².
__
In the attached, x is the length of one side. The area versus side length is plotted. The maximum is seen to be 625 ft² for a side length of 25 ft.
