Answer:
We need to put $801.88 amount in the bank.
Step-by-step explanation:
given that
t=3 yr
Need amount $850 after 3 yr so P= $850
Interest rate=2%
We know that for simple interest

Where r is the Interest rate,t is the time,A is the present amount and P is principle amount after t time.
Here given that P= $850
So now putting the values

So A=$801.88
We need to put $801.88 amount in the bank.
Step-by-step explanation:
- factor the numerator and denominator and then cancel the common factors
- ans x⁴ +4 + 1/x
Answer:
(2w-1)/5+w+2=2w
We simplify the equation to the form, which is simple to understand
(2w-1)/5+w+2=2w
Reorder the terms in parentheses
( + 0.4w-0.2)+w+2=2w
Remove unnecessary parentheses
+ 0.4w-0.2+w+2=2w
We move all terms containing w to the left and all other terms to the right.
+ 0.4w+1w-2w=0.2-2
We simplify left and right side of the equation.
-0.6w=-1.8
We divide both sides of the equation by -0.6 to get w.
w=3

Answer:
Associative property of addition
Step-by-step explanation:
The associative property of addition is as follows :
a+(b+c) = (a+b)+c
We have,
a = 8, b = 9 and c = 3
So,
Using above property,
(8+9)+3 = 8+(9+3)
20 = 20
Hence, this is the required solution.
Answer:
Variance = 25
Step-by-step explanation:
<em>Standard deviation is the under root of variance.</em>
<em>Variance is the square of standard deviation.</em>
<u>Data:</u>
Mean = 70
Variance = ?
Standard deviation = √variance = 5
Variance = 5²
Variance = 25.
Therefore, the variance is 25.
