Answer:
"GPS technology may accidentally leak confidential information about the location."
Explanation:
A good case in point was a watch tracking service that leaked classified GPS coordinates of our military servicemen and women's location. It jeopardized our ability to effectively operate in a foreign land without notice of occupied territory.
In this question, it places our military and journalists at risk because they know where they are at and so forth.
Ryan's Sparkling Jewels estimated its payroll for the coming year to be $84,000. Its workers' compensation insurance premium rate of 0.6% is paid at the beginning of each quarter required: Calculate the estimated cost of workers' compensation insurance for the year.
Answer:
$504 per year
$126 per quarter
Explanation:
workers' compensation insurance = payroll x insurance rate.
$84,000 x 0.6%
$84,000 x 0.006 = $504 per year
$504 ÷ 4 = $126 per quarter
The closest to the minimum number of consumers needed to obtain the estimate with the desired precision is (b) 271
Explanation:
When the prior estimate of population proportion is not given , then the formula to find the sample size is given by :-
where E = Margin of error.
z* = Critical z-value.
As per given , we have
E = 5%=0.05
Confidence level = 90%
The critical value of z at 90% is 1.645 (By z-table)
Put all values in the formula , we get
n=0.25(1.645/0.05)²
n=0.25(32.9)²
n=270.6025≈271
Thus, the minimum sample size needed = 271
Hence , the correct answer is 271 .
Answer:
So unit elastic at q = 5
inelastic above 5
and elastic below 5
Explanation:
The elasticity is determianted by the marginal revenue.
Our first goal is to find the marginal revenue function
p = 40 - 4q
total revenue(TR) = quantity times price
q x (40 - 4q) = -4q^2 +40q
marginal revenue TR(q)/d(q) = -8q + 40
Now, with this fuction the economic analisys states that a demand is unit elastic when marginal revenue is zero.
It will be inelastic below zero and elastic above zero
MR will be zero when q = 5
-8(5) + 40 = 0
As quantity increases the demand will be inelastic
