Answer:
Step-by-step explanation:
If 2% × 410 = 8.2 => Divide 8.2 by 410And see if we get as a result: 2% Note: Multiply a number by the fraction 100/100, and its value doesn't change.
Answer:
option A, Estimation gives an approximate answer
You will need to use this formula:
Principal = Total ÷ (1 + Rate) ^ <span>years
</span><span>Principal = 35,000 / [1.08]^4
</span><span><span><span>Principal = 35,000 / 1.36048896
</span>
</span>
</span>
Principal =
<span>
<span>
<span>
25,726.04
</span>
</span>
</span>
So, you would have to deposit $25,762.04 @ 8 per cent to have 35,000 in four years.
Answer:
n = 100 scores from a population with σ = 20
Step-by-step explanation:
The Central Limit Theorem estabilishes that, for a random variable X, with mean 
and standard deviation 
, the sample means with size n can be approximated to a normal distribution with mean and standard deviation, which is also called standard error, of 
n = 5 scores from a population with σ = 20
n = 5 scores from a population with σ = 80
n = 100 scores from a population with σ = 20
.
This one is the correct answer.
n = 100 scores from a population with σ = 40
.
