Equation required for this question:
an • 1.072^n = 14,580
Where a = payment every half year and n = number of half years
There are 12 half years in 6 years.
Therefore n = 12, substitute this.
12a • 1.072^12 = 14,580
12a = 14,580 / 1.072^12
12a = 6,330~
a = 527.5 ~
Answer:
t=5W+30 or C
Step-by-step explanation:
The pool already has 30 in it so you would initially be adding it, not multiplying it to anything. Then since every second 5 gallons of water is being added to the pool, you add the 30 gallons the pool already contains to 5W.
Basically
just put the coeficinets of each variable in the apropriate row
example
ax+by=c and
dx+ey=f
would go in like this
so
3x+1=1 and
0x-1y=5
D is answer
The probability of an event being very likely means that it has a high chance of occurring, or the probability is close to 1. Remember that with probability, it goes from 0 to 1 only. There are no negatives, and it is all decimals.
Therefore, the correct answer is C. 0.89. This is because there is almost a 90% chance of the event occurring, as the probability is 0.89.
Hope this helps!! :)
Answer:
C
Step-by-step explanation:
If you plug the coordinate pairs in, C is the only one in which keeps both equations true.
