The area of the semicircle having a radius of 19.6 meters is
603.68 [tex]m^{2}[/tex].
Detailed Answer:
The formula for the area of a circle is π[tex]r^{2}[/tex]. Therefore, the formula for the area of a semi-circle is ([tex]\frac{1}{2}[/tex] π[tex]r^{2}[/tex]).When the calculation is done
[tex]\frac{1}{2}[/tex] ×[tex]\frac{22}{7}[/tex] × 19.6 × 19.6 = 603.68 meters squared.

1. Total spending in the US on lotteries in 2017 was about $75 billion. Given a US Population of 325
million of which 23% are under age 18, and the fact that about half of American adults play the
lottery in any given year, about how much does the average American spend on lotteries each
year?
Based on the statistics, an average American spends $299.7 on lotteries each year
How to determine the amount an American spend on lotteries?The population is given as:
Population = 325 million
23% are under the age of 18.
This means that this category is not eligible to play lotteries.
The eligible population is:
Eligible = (1 - 23%) * 325 million
Evaluate
Eligible = 250.25 million
The total amount is given as:
Total = $75 billion
So, the amount spent by each is:
Amount = Total/Eligible
This gives
Amount = $75 billion/250.25 million
Evaluate
Amount = $299.7
Hence, an average American spends $299.7 on lotteries each year

Based on the account receivable balance and the adjustments, the adjusting entries for doubtful debt under various assumptions is:
a. $23,900b. $47,900c. $47, 800d. $34,300What are the entries for doubtful debt?a. Bad debt is 1/4 of 1% of sales:
= 9,560,000 x 0.25%
= $23,900
b. Debit balance of $11,400:
= Estimated doubtful accounts + Debit balance

nth term for 300,250,200
The nth term of the arithmetic sequence 300,250,200 is 350-50n if the common ratio is -50
What is a sequence?It is defined as the systematic way of representing the data that follows a certain rule of arithmetic.
We have an arithmetic sequence:
300,250,200
The first term a = 300
Common difference d = 250-300 = -50
nth term:
A(n) = a + (n-1)d
A(n) = 300 + (n-1)(-50)
A(n) = 300 -50n + 50
A(n) = 350—50n
Thus, the nth term of the arithmetic sequence 300,250,200 is 350-50n if the common ratio is -50

The 73 customers who spend money in this store if a MOE of at most 0.075 with 80% confidence.
What is the margin of error(MOE)?MOE is an error that provides an estimate of the percentage of errors in real statistical data.
The formula for finding the MOE:
MOE = z x s/√n
Where ,
Z = the z-score at the confidence interval
s = the standard deviation
n = the number of samples.
We have p = 0.50 MOE = 0.075
Z = 1.282 at 80% confidence
0.075 = 1.282 x √0.50(1- 0.50)/ n
After solving,
n = (0.5)(0.5)/(0.0585)²
n = 73
