First, we need the total number of people that used transportation. 
8+20+20+32 = 80
Next, we can make a ratio that represents the number of people who used bikes out of the total number of people. 8/80. Next, we set this equal to the ratio x/100 with x being the percent of people who used a bike.
8/80 = x/100
Finally, we solve for x. 
(100*8)/80 = x
800/80 = x10 = x
x equals 10, meaning 10% of people surveyed used a bike to get to the park.

Each bag of Skittles is supposed to have at least 30 Skittles. A machine that fills bags has a 0.005 probability of under fillin
telo118 [61]

Answer:

The standard deviation for the number of bags that are underfilled is 2.236.

Step-by-step explanation:

In a Poisson distribution, the probability that X represents the number of successes of a random variable is given by the following formula:

P(X = x) = \frac{e^{-\mu}*\mu^{x}}{(x)!}

In which

x is the number of sucesses

e = 2.71828 is the Euler number

\mu is the mean in the given interval. The variance is the same as the mean, which mean that the standard deviation is the square root of the mean.

In this question:

Expected number of underfilled bags in a sample of n bags is:

\mu = 0.005*n

1000 bags, so

\mu = 0.005*1000 = 5

Standard deviation S = \sqrt{5} = 2.236

The standard deviation for the number of bags that are underfilled is 2.236.
