Answer: B
Step-by-step explanation:
So what you do is multiple 14000x.06 which is 860 dollars per month now since there is 12 months in a year and ten years multiple 10x12 which is 120 so then multiply 120x860 because its 6 percent of 14000 is 860 so then that’s how much is put in each month after ten years which is 120 months you multiply them together to get 100,800
Answer:
a) rCn = 1176
b) 2352
Step-by-step explanation:
a)Each committee should be formed with 3 members ( no two members could be of the same state) then
Let´s fix a senator for any of the 50 states so in the new condition we need to combined 49 senators in groups of 2 then
rCn = n! / (n - r )! *r!
rCn = 49!/ (49 - 2)!*2!
rCn = 49*48*47! / 47!*2!
rCn = 49*48 /2
rCn = 1176
So we can choose in 1176 different ways a senator for a given state
b) To answer this question we have to note, that, 1176 is the number of ways a committee can be formed with senators of different sate (taking just one senator for state ) if we have 2 senators we need to multiply that figure by 2.
1176*2 = 2352
Given:
Value of gold = 8,590
decrease in value = 3%
8,590 * 3% = 257.70 amount lost due to recession.
8,590 - 257.70 = 8,332.30 new value of gold.
