Solution-
First 9 letters of alphabet are- A,B,C,D,E,F,G,H,I
Total number of ways of selection of 4 letters from 9 alphabets = 9C4
=9!÷((4!).(9-4)!) = 9!÷(4!×5!) = (9×8×7×6)÷(24) = 126
The number of ways of arranging these 4 numbers = 4! = 24
∴ Total number of possible permutations = 9C4×4! = 126×24 = 3024
∴ option number 2 is correct.
Diversification means that you invest in "Multiple investments to split up your currency to the make more investments to profit more of your currency." Obviously depending on the percentage of potential growth in the investment you chose.

Hello,
x²/25+y²/9=1
a=5, b=3 c²=a²-b²=25-9=16=4²
Foci are (0,4) and (0,-4)
Answer C
============
Answer:
2ab(7a^4b^2+ a^5×b-2a)
start with multiple 2ab into the equation
(2ab×7a^4b^2)+(2ab×a^5×b)-(2ab×2a)
((2×7)a^(4+1)b^(2+1))+(2×a^(5+1)×b^(1+1))-((2×2)a^(1+1)×b)
14×a^5×b^3+2×a^6×b^2-4×a^2×b
Answer:
D. 4, B. 4, C. 8
Step-by-step explanation:
The data are centered around 4; the plot is pretty evenly spread out around the center, 4 miles. (The actual average is 3.88.)
The most number of miles run (look for tallest column of dots) is 4.
The number of people who ran is 8 (count the dots above the 5-mile label).
