1) Let's simplify those expressions making use of exponents rules:
Note that the exponent outside the parenthesis is 'distributed' over each term inside.
2) Similarly for the second expression we can state that:
Please help me I dont know the answer
1 answer:
Okay so the range is the largest number - the smallest number.
So 25 - 11 = 14
The Absolute Mean Deviation is going to be a bit harder to explain, just go with it.
So we first calculate the mean.
119 ÷ 7 = 17
Now we calculate the distance each value is from 17. (SEE ATTACHMENT)
What happens next is that you take those values that are the distance from 17 and you add those up and calculate the mean of that.
28 ÷ 7 = 4
The Absolute Mean Deviation is 4.
I'll figure out the bottom in a minute. But this is all I got for you so far.

Answer:
(a)∴A=$6753.71.
(b)∴A=$1480.24
(c) ∴P=$7424.70
(d)∴P=$49759.62
(e)∴P=$5040.99
(f) ∴P=$2496.11
Step-by-step explanation:
We use the following formula
A=amount in dollar
P=principal
r=rate of interest
(a)
P=$2,500, r=5%=0.05,t =20 years , n= 4
=$6753.71
∴A=$6753.71.
(b)
P=$1,000, r=8% =0.08,t =5 years , n= 2
=$1480.24
∴A=$1480.24
(c)
A=$10,000, r=6% =0.06,t =5 years , n= 4
∴P=$7424.70
(d)
A=$100,000, r=6% =0.06,t =10 years , n= 12
∴P=$49759.62
(e)
A=$100,000, r=10% =0.10,t =30 years , n= 12
∴P=$5040.99
(f)
A=$100,000, r=7% =0.07,t =20 years , n= 4
∴P=$2496.11
