The answer is (A) which is 32..
If u can f(x) =160 when x=40 and if we divide 160 by 40 we get 4..
Therefore we can say that to get the f(x) we have to multiple the value of x by 4.
. *NB: as the value of x=40, f(x) is: 40×4=160
. * Therefore as the value of x=8, f(x) is: 8×4=32

Answer:
2. 4
Step-by-step explanation:
The "initial value" is the y-value corresponding to x=0. That is given in the first line of the table.
The initial value is 4.
Answer:
The mean of the number of restaurants that failed within a year is 28.38 and the standard deviation is 4.02.
Step-by-step explanation:
For each restaurant, there are only two possible outcomes. Either it fails during the first year, or it does not. The probability of a restaurant failling during the first year is independent of other restaurants. So we use the binomial probability distribution to solve this question.
Binomial probability distribution
Probability of exactly x sucesses on n repeated trials, with p probability.
The expected value of the binomial distribution is:
The standard deviation of the binomial distribution is:
In the city where she lives, the probability that an independent restaurant will fail in the first year is 43 %.
This means that
66 independent restaurants
This means that
Mean:
Standard deviation:
The mean of the number of restaurants that failed within a year is 28.38 and the standard deviation is 4.02.
