Answer:

Step-by-step explanation:
step 1
Find the length side of the smaller square
The area of the square is equal to

so


step 2
Find the length side of the larger square
The area of the square is equal to

so


step 3
Find the value of x
Applying the Pythagoras Theorem

substitute the values



Total = principal * (1 + rate/n)^n*years
where "n" is the number of compounding periods per year
Total = 10,000 * (1 + .044/4)^4*2
Total = 10,000 * (1<span>.011</span>)^8
<span><span>Total = 10,000 * 1.0914635699
</span>
</span><span><span>Total = </span>
10,914.64

Answer:
y = -2x - 1
Step-by-step explanation:
y = mx + b
slope = m
y = -2x + b
5 = -2x * -3 + b
5 = 6 + b
-1 = b
y = -2x - 1

Answer:
0.25
Step-by-step explanation:
Answer:
The sample size is 183.
Step-by-step explanation:
Given:
σ = $1050, ppulatin standard deviation
99% confidence interval
Accuracy = +/- $200
The accuracy is given by
z*(σ/√n)
where
z* = 2.576 for 99% confidence level (from tables)
n = sample size
Therefore
2.576(1050/√n) = 200
√n = (2.576*1050)/200 = 13.524
n = 182.9
<em>The sample size is 183</em>
