Answer:
A=9675.299
Step-by-step explanation:
A=p(1+r)^t
A compound amount
P is the principle amount invested
r : rate ( semiannually is 0.5 )
t=years ( semiannually 12*2=24)
A=3000(1+0.10/2)^24
A=9675.299
Answer:
12
Step-by-step explanation:
Just add three
Answer:
24
Step-by-step explanation:
Given the solution
2 < x ≤ 24
The ≤ symbol means less than or equal to
Thus x can equal 24
At the other end 2 < x which means x cannot equal 2
Thus x = 24 will make the inequality true
Answer:
d) r = -65.
Step-by-step explanation:
The absolute value of r represents the relationship strength and the sign represents the relationship direction
Also if the relationship is nearest to 1 then it would be termed as positive correlated and if the relationship is nearest to -1 then it would be termed as negative correlated
Therefore based on the given options, the last option is correct
