The probability that a randomly selected pigeon gets an incorrect result is; 0.0103
<h3>How to find the Probability?</h3>
We are told that;
1.5% pigeons are infected.
Inaccuracy of the test = 1 - 97% = 3%
1.5% of the pigeons are infected. Thus;
1 - 1.5% = 98.5% pigeons are un-infected.
Inaccuracy of test is 1 - 99% = 1% .
Thus;
0.03 and 0.01 are the probability of an error being made in infected and un-infected respectively.
Meanwhile, probability of infected and un-infected are 0.015 and 0.985 respectively.
Thus, the probability of a randomly chosen person gets an incorrect result = (0.03*0.015) + (0.985*0.01) = 0.0103

Answer:
Yes, the graph makes it appear as if sales increased three folds.
Step-by-step explanation:
The graph presented by the advertising company is misleading, as it attempts to exaggerate the effect of its advert on sales. This can be attributed to the scale which is isn't uniform.
Last year sale was about 137000 and it grew to 150000 as a result of advertisement.
But from the bar chart, it seems there was three times increase in sales.
Answer:
Nominal interest rate is = 9% converible quaterly
we need to find monthy effective interest rate
0.09
i = 0.00744 or 0.75% approximately
i can also be taken as = 0.09/12
now PV of annuity will be the market price i.e x
6 60 *2 ---------------------a
Multiply equation by \frac{1}{1+i} both sides
6 60 2 PV ---------------b
Subtract equation b from a
60 2 PV (1 1+i (1+2)1 (1+2)2 (1+2)3 (1+2)60 (1+961
60 2 PV( 1 +i
on putting i = 0.00744
PV = 2733.88 approximately
X = 2733.88
Step-by-step explanation:
No the student is incorrect the answer is actually 332
