This is binomial
distribution problem. <span>
We are given that:</span>
n = sample size = 500
p = proportion which
burns wood = 0.27,
q = proportion which
does not burn wood = 1-p = 0.73
<span>
A. Mean is calculated as:</span>
Mean = n*p
Mean = 500 * 0.27
Mean = 135
<span>
B. Variance is calculated as:</span>
Variance = n*p*q
Variance = 500*0.27*0.73
Variance = 98.55
<span>
C. Standard deviation is calculated as:</span>
Standard deviation = sqrt(variance)
Standard deviation =
sqrt(98.55)
<span>Standard deviation =
9.93</span>
Answer:
the self-employment tax is $7,065
Explanation:
The computation of the self-employment tax is given below:
Given that
net profit = $50,000
Now the 92.35% of net profit is $46,175
As it is lower than $128,400
So,
= 15.3% of $46,175
= $7,065
Hence, the self-employment tax is $7,065

Answer:
$575
Explanation:
Given that,
Opening office supplies = $1,100
Closing office supplies = $475
Office supplies expense for the month = $1,200
Opening stock + Purchases - Closing stock = Consumption
$1,100 + Purchases - $475 = $1,200
$625 + Purchases = $1,200
Purchases = $1,200 - $625
= $575
Therefore, the amount of office supplies was purchased during February is $575.
