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:
b. Only Emerald Corporation's current ratio will be increased.
Explanation:
Given that
Emerald current ratio is
= 0.5 i.e. = 0.5 ÷ 1
now in case when the current liability is doubles , so the current assets is
= 0.5 + 1 = 1.5
And, the cuurrent liabilities is
= 1 + 1
= 2
so new ratio is
= 1.5 ÷ 2
= 0.75
Now
Ruby current ratio is
= 1.5
i.e. = 1.5 ÷ 1
Now in case when the current liability is doubled,
the current assets is
= 1.5 + 1
= 2.5
And, current liabilities is
= 1 + 1
= 2
Now new ratio is
= 2.5 ÷ 2
= 1.25
Therefore the emerald current ratio is rised from 0.5 to 0.75
And, the Ruby's ratio has decline from 1.5 to 1.25

Answer: net exports
Explanation:
Balance of payment simply shows the estimation of the inflows and outflow of a nation's money for a certain year. It should be noted that current account of the balance of payment consists of three main components which are the trade in Goods, the trade in services, and the transfer payments.
The trade in goods is segregated into imports and export. This therefore makes the net exports volatile and vital because it has higher share in a current account.
