The residence of a city voted on whether to raise property taxes the ratio of yes votes to no votes was 7 to 4 if there were 367

Tresset [83]

Answer: 10,098 votes

Step-by-step explanation:

The ratio is 7 : 4 which means that for every 7 yes votes, there were 4 no votes.

To find the total votes, add the ratios:

= 7 + 4

= 11

4/11 are the no votes out of the total. Assuming the total is x, the formula is:

4/11x = 3,672

x = 3,672 / 4/11

x = 10,098 votes

For a binomial process, the probability of success is 40 percent and the number of trials is 5. Find the standard deviation.

Yakvenalex [24]

Answer:

$Sd(X) =\sqrt{1.2}=1.095$

Step-by-step explanation:

Previous concepts

The binomial distribution is a "DISCRETE probability distribution that summarizes the probability that a value will take one of two independent values under a given set of parameters. The assumptions for the binomial distribution are that there is only one outcome for each trial, each trial has the same probability of success, and each trial is mutually exclusive, or independent of each other".

Solution to the problem

Let X the random variable of interest, on this case we now that:

$X \sim Binom(n=5, p=0.4)$
