Answer:
The answer to your question is 10 units ²
Step-by-step explanation:
To solve this problem I will use the formula
3 3
A = 1/2 3 -1 = 1/2 [ (3 x -1) + (3 x -5) + (-2 x 3) - (3 x -5) - (-2 x -1)
-2 -5 -(3 x 3)]
3 3 = 1/2 [ -3 - 15 - 6 + 15 - 2 - 9]
= 1/2 [ -20]
= 1/2|20|
= 10 units²
Sorry, I don't remember how to use the formula 1/2 b x h
Given:
n = 48, the sample size
m = $25,000, th sample mean
σ = $3000, the maximum variance
The standard deviation is
s = √σ = √(3000) = 54.772
As a rule of thumb, the range is 4 times the standard deviation. Therefore the range is
R = 4*54.772 = 219.09
Half the range is
R/2 = 219.09/2 = 109.45
The required range is
(25000-109.45, 25000+109.45) = (24890.46, 25109.54)
Answer: ($24,890.46, $25,109.54)
Answer:
Accumulated amount will be $2504.90.
Step-by-step explanation:
Formula that represents the accumulated amount after t years is
A = 
Where A = Accumulated amount
= Initial amount
r = rate of interest
n = number of times initial amount compounded in a year
t = duration of investment in years
Now the values given in this question are
= $1000
n = 12
r = 4.6% = 0.046
t = 20 years
By putting values in the formula
A = 
= 
= 
= 1000×2.50488
= 2504.88 ≈ $2504.90
Therefore, accumulated amount will be $2504.90.
- False. All whole numbers are integers.
- False. For example, 1/2 is a rational number but not a whole number.
- False. For example, -3 is an integer but not a whole number.
- True. All integers are included in rational numbers.
