In a study, 44% of adults questioned reported that their health was excellent. A researcher wishes to study the health of people living close to a nuclear power plant. Among 14 adults randomly selected from this area, only 3 reported that their health was excellent. Find the probability that when 14 adults are randomly selected, 3 or fewer are in excellent health. Group of answer choices
Answer:
Step-by-step explanation:
Probability(P) (k events out of n trials) = nCk * p^k * (1-p)^(n-k), where p=0.40, n=10 and nCk is the number of combinations of n things taken k at a time
:
P ( k < or = 3 ) = P ( k = 3 ) + P ( k = 2 ) + P ( k = 1 ) + P ( k = 0 )
:
P ( k = 3 ) = 10C3 * (0.40)^3 * (0.60)^(10-3) = 0.2149
:
P ( k = 2 ) = 10C2 * (0.40)^2 * (0.60)^(10-2) = 0.1209
:
P ( k = 1 ) = 10C1 * (0.40)^1 * (0.60)^(10-1) = 0.0403
:
P ( k = 0 ) = 10C0 * (0.40)^0 * (0.60)^(10-0) = 0.0060
:
******************************************************************************
P ( k < or = 3 ) = 0.2149 + 0.1209 + 0.0403 + 0.0060 = 0.3821 is approximately 0.38
The probability that when 14 adults are randomly selected and 3 or fewer are in excellent health is 0.072
What is probability ?Probability shows possibility to happen an event, it defines that an event will occur or not. The probability varies from 0 to 1.
Given that,
The percentage of adults who reported their health was excellent = 44 %
The probability of excellent health P = 0.44
The probability of not excellent health = Q - 1 - 0.44 - 0.56
Since, 14 adults are randomly selected.
To find the probability that 3 or fewer are in excellent health,
Use formula
Probability = [tex]^nC_rP^n Q^{n-r}[/tex]
Where P = probability to happen an event, and Q= probability to not happen an event.
The probability that 3 or fewer are in excellent health
= [tex]^{14}C_3 (0.44)^3(0.56)^{14-3} +^{14}C_2(0.44)^2(0.56)^{14-2}+^{14}C_1 (0.44)^1(0.56)^{14-1} + ^{14}C_0 (0.44)^0(0.56)^{14}[/tex]
= 0.0526 + 0.0167 + 0.00328 + 0.000298
= 0.072282
The required probability is 0.072282.

3 coffees and 4 donuts cost $10.05. In the same cafeteria, 5 coffees and 7 donuts cost $17.15. How much do you have to pay for 4 coffees and 6 donut
Answer
You need to pay $14.20 to get 4 coffees and 6 donuts.
Explanation
Let's say that the price of one coffee and x and the price of one donut is y.
In the first instance, 3x+4y=10.05.
In the second instance, 5x+7y=17.15.
You can use these equations to find the value of a coffee and the value of a donut.
We can find x and y using elimination. To do this, you should add or subtract one equation from another to "get rid" of a variable (I'll "get rid" of x). We can't just add or subtract the equations right now, since that wouldn't lead to 0x.
Multiply the first equation by 5, and the second equation by 3. After this, both equations will have 15x. Make sure to multiply each term by 5 and 3.
15x+20y=50.25. This means that 15 coffees and 20 donuts is $50.25.
15x+21y=51.45. This means that 15 coffees and 21 donuts is 51.45.
Now since there are an equal number of coffees, we can subtract these equations.
(15x+21y=51.45)-(15x+20y=50.25) equals y=1.20 (a donut costs $1.20).
Plug the price of the donut into y to find x; 3x+4(1.20)=10.05. The value of x is 1.75. The price of a coffee is 1.75.
You can multiply 1.75 by 4 to find the price of 4 coffees and 1.20 by 6 to find the price of 6 donuts.
1.75*4 is 7.00 and 1.20*6 is 7.20.
You can add those to find the total price; 7.00+7.20=14.20.

3 =f
Step-by-step explanation:
Since this is a right triangle, we can use trig functions
tan theta = opp/ adj
tan 60 = f/ sqrt(3)
sqrt(3) tan 60 = f
sqrt(3) * sqrt(3) = f
3 =f
Suppose f(x) = loga(x) and f(7) = 2. Find f(343)
Answer:
6
Step-by-step explanation:
The given function to us is ,
[tex]\rm\implies f(x)= log_a(x) [/tex]
And its value at 7 is 2 , that is ,
[tex]\rm\implies f(x)= log_a(7) =2[/tex]
Taking this ,
[tex]\rm\implies 2= log_a(7) [/tex]
In general we know that ,
[tex]\bf\to log_a b = c ,\ then \ a^c = b [/tex]
Using this , we have ,
[tex]\rm\implies a^2 = 7 [/tex]
Squarerooting both sides ,
[tex]\rm\implies a =\sqrt{ 7 }[/tex]
Therefore , when x is 343 ,
[tex]\rm\implies f(343)= log_{\sqrt7} ( 343) [/tex]
We can write , 343 as 7³ ,
[tex]\rm\implies f(343)= log_{\sqrt7}7^3 [/tex]
[tex]\rm\implies f(343)= log_{7^{\frac{1}{2}}} 7^3 [/tex]
This can be written as ,
[tex]\rm\implies f(343)= \dfrac{ 3}{\frac{1}{2}} [/tex]
[tex]\rm\implies \boxed{\blue{\rm f(343)= 6 }}[/tex]
Hence the required answer is 6.

Answer:
attributed to enhanced NAVs made possible by brands’ disclosure in the Balance
Sheet. However, there is a biggest handicap of reliable and independent assessment
of the brand value. This is the single most important reason for the brands not
allowed to be placed on the Balance Sheet by the Authorities concerned. Though,
value is assigned to externally acquired brands, there is no effective way for
assessment of home-grown brands. Nevertheless, it is gratifying to note that the
Institute of Chartered Accountants of England and Wales (ICAE & W), has given due
recognition to the internally generated brand values and allow disclosure in the
Balance Sheet which necessitates periodic revaluation.
The brands are to be explicitly recognized, as part of purchased Goodwill, by the
ICAI of India, which would make possible the recognition of brand values. Rules and
methodologies necessary for the valuation accounting and disclosure of brands may
be framed in this regard. This would go a long way in governing the brand
accounting practice and contribute to healthy business combinations in India,
especially where the brand values are given serious consideration in the emerging
strategic alliances, mergers and acquisitions fueled by the entry of MNCs. This
assumes special significance in the environment of globalization, liberalization and
privatization of Indian economy.
It emerges from the above discussions that Goodwill, brand valuation and
accounting are definite to take the world of accounting by storm in the near future
which would mark the beginning of a new era of accounting practice. Thus, there
exists a strong and a clear case for brand accounting, especially in view of the
imminent benefits of brand accounting to the corporate bodies and the investors alike.

Consider the probability that more than 97 out of 120 people will get the flu this winter. Assume the probability that a given person will get the flu this winter is 97%. Specify whether the normal curve can be used as an approximation to the binomial probability by verifying the necessary conditions.
Answer:
Since [tex]n(1-p) = 3.6 < 5[/tex], the normal distribution cannot be used as an approximation to the binomial probability to approximate the probability.
Using the binomial distribution, 100% probability that more than 97 out of 120 people will get the flu this winter.
Step-by-step explanation:
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
In which [tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
And p is the probability of X happening.
Can be approximated to a normal distribution, using the expected value and the standard deviation.
The expected value of the binomial distribution is:
[tex]E(X) = np[/tex]
The standard deviation of the binomial distribution is:
[tex]\sqrt{V(X)} = \sqrt{np(1-p)}[/tex]
Normal probability distribution
Problems of normally distributed distributions can be solved using the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
When we are approximating a binomial distribution to a normal one, we have that [tex]\mu = E(X)[/tex], [tex]\sigma = \sqrt{V(X)}[/tex].
Assume the probability that a given person will get the flu this winter is 97%.
This means that [tex]p = 0.97[/tex]
120 people
This means that [tex]n = 120[/tex]
Verifying the necessary conditions.
[tex]np = 120*0.97 = 116.4[/tex]
[tex]n(1-p) = 120*0.03 = 3.6[/tex]
Since [tex]n(1-p) = 3.6 < 5[/tex], the normal distribution cannot be used as an approximation to the binomial probability to approximate the probability. Thus, the binomial distribution has to be used.
Probability using the binomial distribution:
[tex]P(X > 97) = P(X = 98) + ... + P(X = 120)[/tex]
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]P(X = 98) = C_{120,98}.(0.97)^{98}.(0.03)^{22} \approx 0[/tex]
Probability close to 0, but below the mean, which means that the probability of the number being above this is 100%.
Using the binomial distribution, 100% probability that more than 97 out of 120 people will get the flu this winter.

After a special medicine is introduced into a petri dish full of bacteria, the number of bacteria remaining in the dish decreases rapidly.
The relationship between the elapsed time t, in seconds, and the number of bacteria, B(t) in the petri dish is modeled by the following function:
B(t) = 9300 x (1/64)^t
Complete the following sentence about the rate of change of the bacterial culture
The bacterial culture loses 1/2 of its size every_______ seconds
Answer:
1/6
Step-by-step explanation:
We want to find how long it takes for the bacteria to lose half its size. We can do this by taking one point of the bacteria and finding how long it takes to go to half its size. When t=0, 9300 * (1/64)^t = 9300 * 1 = 9300 as anything to the power of 0 is 1. Therefore, we can solve for t when the end result of the bacteria is 9300/2= 4650, making our equation
4650 = 9300 * (1/64)^t
divide both sides by 9300
1/2 = (1/64)^t
First, we can tell that 2^6 = 64*. Because of this, we can say that (1/2)^6 = 1^6/2^6 = 1/64, so (1/64)^(1/6) = 1/2. We know this because
(1/2)^6 = 64
take the 6th root of both sides
(1/2) = (64)^(1/6)
. This means that t=1/6, so the bacterial culture loses 1/2 of its size every 1/6 seconds

Find an equation of the tangent to the curve at the point corresponding to the given value of the parameter. x=t−t−1, y=1+t2, t=1
Answer:
Step-by-step explanation:
First, I would find the point on the curve. By substituting t=1, I get (x, y). Next, I will try to eliminate the t and make a xy equation. In this case, the t's will cancel out in 'x=t-t-1" which wouldnt make this a curve. To find the equation of the tangent line, find the deretitave of the xy equation, and subsitute x in to find the slope at that point. Next, use point slope form to find the equation at the point.
