Many retail stores offer their own credit cards. At the time of the credit

application, the customer is given a 10% discount on the purchase. The time required

for the credit application process follows a uniform distribution with the times

ranging from 4 minutes to 10 minutes.

a. Show the uniform distribution

b. Show that the area under the curve is equal to 1.

c. What is the mean time for the application process?

d. What is the standard deviation for the process time?

e. What is the likelihood a particular application will take less than 6 minutes?

f. What is the likelihood a particular application will take more than 5 minutes?

True or False

a. Based on a classical approach, the probability of an event is defined as the number of

favorable outcomes divided by the total number of possible outcomes.

b. To apply the special rule of addition, the events must be independent

c. To apply the special rule of addition, the events must be mutually exclusive

d. A coin is tossed four times. The probability is ¼ or 0.25 that all four tosses will result

in a head face up

e. A combination of a set of objects is defined by the order of the objects

f. Two coins are tossed. The tossing the coins is called an experiment, and one possible

event is two heads

g. The combination formula is: n! / (n - r)!

h. If two events are mutually exclusive, then P(A or B) = P(A) P(B).

I. A probability is a number from -1 to +1.

j. The closer a probability is to 0, the more likely the event will happen

The Apollo Space program lasted from 1967 until 1972 and included 13 missions. The missions lasted from as little as 7 hours to as long as 301 hours.

The duration of each flight is listed below:

9 / 195/ 241/ 301/ 216/ 260/ 7/ 244/ 192/ 147/ 10/ 295/ 142

a. Is the date given a sample or population? Explain why?

b. Find the mean, median and mode

c. Find the range, variance and standard deviation of the flight times

1.) Are Statistics used as a basis for making decisions. True / False

2.)The CIA World Factbook cited these numbers for the United States: • Birthrate is 14.14 births per 1,000 population

• Average life expectancy for females is 80 years

• Approximately 290 million persons residing in the United States Each of these numbers is referred to as statistic? True or False

3.) Is Statistics defined as a body of techniques used to facilitate the collection, organization, presentation, analysis and interpretation of information for the purpose of making better decisions.

True / False

4.)The order that runners finish in a race would be an example of continuous data. True/False

5.) The number of children in a family is a discrete variable. True/ False

6.) Is the principal difference between the interval and ratio scale is that the ratio scale has a meaningful zero point. True / False

7.) Is Categorizing voters as Democrats, Republicans and Independents is an example of interval level measurement. True / False

These are Questions I was iffy on and couldn't find them in the textbook. Thanks For the assistance :)

Suppose you have a rational function that it's denominator is (X-c) and numerator can be any function. Suppose you need to find the limit of this rational function given as x goes to value c. Can you always say that for this problem the limit does not exist? I need an explanation please see can see why

Change each logarithmic expression to an expression involving an exponent ?

I need help with these math problems (Not logarithms) Thanks 5^x = 1/25?

1.) 5^x = 1/25 ?

2.) 4^(11-3x) = 16^x ?

(Logarthims problems)- Im having trouble with?

3.) 2^2 = 20

4.) log(5) 12 = x

1.) 6^3 = 216 ?

I think is log(6) 216 =3

2.) 10^x = 1000 ?

3.) e^3.2 = x ?

1.) 6^3 = 216 ?

I think is log(6) 216 =3

1.) An in ground backyard pool can be filled in 12 hours if water enters through a pipe alone, or in 30 hours if water enters through a hose alone. If water is entering through both the pipe and the hose, how long will it take to fill the pool?

2.)A tugboat moves at a rate of 10 mph in still water. It travels 24 miles upstream and 24 miles downstream in a total of 5 hours. What is the speed of the current?
