nikdorinn [45]

<h2>Answer with explanation:</h2>

Given : The probability that telephone bills mailed to house-holds in Hong Kong are incorrect.=0.01

<h2>Binomial distribution :-</h2>

$P(x)=^nC_xp^x(1-p)^{n-x}$

If a sample of 10 bills is selected, then the probability that at least one bill will be incorrect :-

$P(x\geq1)=1-P(0)\\\\=1-^{10}C_{0}(0.1)^0(0.9)^{10}\\\\=1-(0.9)^{10}=0.6513$

Hence, the probability that at least one bill will be incorrect =0.6513

<h2>Poisson distribution: </h2>

$P(x;\mu)=\dfrac{e^{-\mu}\mu^x}{x!}$

Mean : $\mu=np=10\times0.1=1$

Then , If a sample of 10 bills is selected, then the probability that at least one bill will be incorrect :-

$P(x\geq1)=1-P(0)\\\\=1-\dfrac{e^{-1}1^0}{0!}\\\\=1-0.3678=0.6321$

Hence, the probability that at least one bill will be incorrect =0.6321

Vicky starts a new job with an hourly pay of 7.15$. Suppose that her hourly pay increases by 5% each year. What will Vicky’s hou

Bingel [31]

Answer:

$8.28

Step-by-step explanation:

This is a compound growth problem.

The formula is:

$F=P(1+r)^t$

Where F is the future amount (amount in 3 yrs)

P is the initial amount (here, it is 7.15)

r is the rate of growth, in decimal (5% means 5/100 = 0.05)

t is the time , in years ( t = 3)

Now, substituting, we find the hourly wage after 3 years:

$F=P(1+r)^t\\F=7.15(1+0.05)^3\\F=7.15(1.05)^3\\F=8.28$

Hence,

<u>after 3 years, at 5% growth, the new hourly wage would be $8.28</u>
