we know that given terms were i geometric progression.
which means common ratio is same between two consecutive terms .
here we have 8,40,200,1000.
we know that common ratio =second term/first term =40/8=5.
so each and every terms is multiplied by 5 to get next term for this series the term after 1000 is 5000 =1000*5.
in part b we have another series which is having common ratio of -2.
so we need to multiply with -2 to find next term.
80*(-2)=-160.
for part c the common ratio is -2 .
so we need to multiply with -2 *previous term =-2*16 =-32.
The answer would be 12.99% and $187,000.
Solution:
(1.031^4(15) = ( 1+r)^15
60 log 1.031 = 15 log (1 + r)
4log (1.031) = log ( 1 + r)
10^[4log(1.031)] = r + 1
10^[4log (1.031) ] - 1 =
r = 0.1299
= about 12.99%
Answer:
We choose D.
Step-by-step explanation:
The question is which statement is true?
A. 33% of the people surveyed were vegetarian and though saving energy was not important
=> It is wrong because we do not know the total number of people who were surveyed.
B. This statement is wrong, because we also have 26% non - vegetarian though saving energy was not important
C. This statement is wrong, because there are 38% non - vegetarian though saving energy was not important and only 26% non - vegetarian though saving energy was very important
D. True because there are 36% non - vegetarian though saving energy was somewhat important while there are 17% vegetarian think so. Hence, a person who was not a vegetarian was morel likely than a vegetarian to think that saving energy is somewhat important
=> We choose D.
