Hey can you please help me posted picture of question
When Stephan moved from Illinois to Florida, his average monthly electric bill increased from $83 to $102. He is curious to know whether his IL or FL electric bill is relatively more or less expensive, when compared to the distribution of electric bills for each state. In Illinois, the mean monthly electric bill is $85, with a standard deviation of $3.20. In Florida, the mean monthly electric bill is $105, with a standard deviation of $4.00. Compute the z-scores for Stephan's IL and FL electric bills. Round to three decimal places if necessary.
Use the method illustrated in the solutions to Exercise 9.2.39 to answer the following questions. (a) How many ways can the letters of the word DANCER be arranged in a row? Since the letters in the given word are distinct, there are as many arrangements of these letters in a row as there are permutations of a set with elements. So the answer is . (b) How many ways can the letters of the word DANCER be arranged in a row if D and A must remain together (in order) as a unit? (c) How many ways can the letters of the word DANCER be arranged in a row if the letters NCE must remain together (in order) as a unit?

HELP ME I WILL GIVE BRAINLIEST California has a population of approximately 4 × 10^7 people and South Dakota has a population of approximately 8 × 10^5 people.

Answers

The population in California is 50 times greater than the population in South Dakota.

The number of times the population in California is higher than that in South Dakota

To find out how many times greater the population in California is than in South Dakota, you can divide the population of California by the population of South Dakota:

Population of California = 4 * 10⁷

Population of South Dakota = 8 * 10⁵

Population ratio = (Population of California) / (Population of South Dakota)

Population ratio = (4 * 10⁷) / (8 * 10⁵)

Population ratio = 50

Therefore the population in California is 50 times greater than the population in South Dakota.

The probability that a person has a certain disease is 0.03. Medical diagnostic tests are available to determine whether the person actually has the disease. If the disease is actually​ present, the probability that the medical diagnostic test will give a positive result​ (indicating that the disease is​ present) is 0.92. Of the disease is not actually​ present, the probability of a positive test result​ (indicating that the disease is​ present) is 0.01. a. If the medical diagnostic test has given a positive result​ (indicating that the disease is​ present), what is the probability that the disease is actually​ present

Answers

Answer: 0.74

Step-by-step explanation:

A= "The person is sick"

B= "The test gives a positive result"

P(A)=0.03

P(B|A)=0.92

P(B|A')=0.01

P(A')=1-P(A)=1-0.03=0.97

P(B)=P(B|A)P(A)+P(B|A')P(A')=0.92*0.03+0.01*0.97=0.0373

Based in Bayes Rule

P(A|B)=P(B|A)P(A)/P(B)=0.92*0.03/0.0373=0.74

A dolphin ate 2604 pounds of fish during the 31 days in march. What is the average amount of fish the dolphin ate per day.

Answers

To find the average of something you add up all of the data points (in this case it would be how many pounds offish were eaten per day but this is already done for us) then you would divide by the number of points you have (the number of days which is 31). So all you have to do is 2604/31. This equals 84 pounds of fish per day on average.

the dolphin ate

2604 lbs of fish in 31 days

this can also be written as

2604/31

we want the denominator to be 1, since the denominator represents days

to do this, we can divide 31 by 31. but we must do the same to the numerator

2604 ÷ 31 = 84

so our new fraction is

84/1

so per day, the dolphin ate 84 pounds of fish

plzzzzz help me I can fail algebra. on Sunday, Sean ran 5/7 of the distance he ran on Thursday (9/10). fill in the number of miles he ran on Sunday

Answers

Answer:

9/14

Step-by-step explanation:

You multiply the two fractions. So 5/7*9/10, you just multiply across. This would give you 45/70. Then, after simplifying, this fraction is 9/14. So, Sean ran 9/14 of a mile on Sunday. Hope this helps, Sorry if im wrong!!

HELP!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Answers

Answer:

  the correct answer is marked (1/2)

Step-by-step explanation:

The average rate of change is the slope of the line between the two points at the ends of the interval.

  m = (g(3) -g(-4))/(3 -(-4))

The values of the function we need are ...

  g(3) = 5/(3-1) +2 = 2.5 +2 = 4.5

  g(-4) = 5/(-4-1) +2 = -1 +2 = 1

So, the slope is ...

  m = (4.5 -1)/7 = 3.5/7 = 1/2

The average rate of change is 1/2.

On the attached graph, that value shows up as the coefficient of x in the equation of the line through the two points.

Say a business found that 29.5% of customers in Washington prefer grey suits. The company chooses 8 customers in Washington and asks them if they prefer grey suits. What assumption must be made for this study to follow the probabilities of a binomial experiment?

Answers

Answer:

The assumption that must be made for this study to follow the probabilities of a binomial experiment is that there must be only two outcomes of each trail in this study (meaning that it is either they prefer grey suits or they do not prefer grey suits). There must be no other option apart from those two options and each of the independent trails must be mutually exclusive, meaning that the two required options cannot occur together. It is either the first option (prefer grey suits) or the second option (do not prefer grey suits).
