4.) numbers is a game in which you bet $1 on any 3-digit number from 000 to 999. if your number comes up, you get $500. find the expected payback.

Answers

Answer 1

As the probabilities of random variables are negative so we can expect to lose roughly 50 cents on each $1.00 ticket we purchase.

How did the math game function?

The rules of the "numbers" game are simple: a player selects a three-digit number between 000 and 999. Anyone who picks the winning number receives a payout equal to 600 times their original wager. The winning number is decided by a publicly disclosed source. The majority of bets were for $1 or less, and frequently.

What does a probability arrangement mean?

A permutation is an arrangement (or ordering) of a collection of items. (We can also arrange only some of the objects in the set.) The arrangement of the objects in a permutation depends on their order.

The random variable-0.499/1000

The random variable "winning" are $1 and $600.

and their probabilities are 999/1000 and 1/1000, respectively.

The expected "winnings" are calculated as follows:

=(999/1000)(-1)+(1/1000)(500)

=-0.499/1000

=-0.499 cents

so we can expect to lose roughly 50 cents on each $1.00 ticket we purchase.

geoff is about to open a restaurant. he has found two possible locations for the restaurant; one closer to the central business district (cbd) and one in the suburbs. geoff is concerned that if he chooses the cbd location, he will have to charge higher prices for his food to cover the higher rent. geoff is uncertain of the affect that this will have on his annual revenue. to help with his decision, geoff will carry out a multiple regression analysis to predict the annual revenue earned by restaurants based on their distance from the cbd in miles and the average price in dollars charged for a dish. geoff has collected a sample of 50 restaurants that are randomly spread around the city. the proximity to the cbd (x1i), average price of a dish (x2i) and annual revenues (yi) were recorded for each of these restaurants (i = 1, 2, ..., 50). Geoff believes that a multiple linear regression is appropriate for this data. After carrying out some analysis, geoff has noticed that moving one mile away from the CBD (assuming that the average price of a dish is held constant) will result in a decrease of $60,000 in annual revenues. Geoff has also noticed that increasing the average price of a dish by $1 (assuming that the distance from the CBD is held constant) will result in an increase of $40,000 in annual revenues. The data shows that a restaurant at the center of the CBD that gave away its food for free would have an annual loss of $20,000. Select the multiple linear regression equation that corresponds to Geoff's analysis: o ĝi = -20,000 - 60,000x11 + 40,000x2i o ĝi = 20,000 + 60,000x11 - 40,000x2i O Vi = -20,000 + 40,000x11 - 60,000x2i © y = 20,000 - 40,000x13 + 60,000x2i

Answers

The multiple regression linear regression equation is:

i = -20000 + -60000*x1i + 40000*x2i

The multiple regression equation here will be of the form

i = a*x1i + b*x2i + c

Where i is the annual revenue

a is the coefficient of x1i which is distance from CBD

where b is the coefficient of x2i average price of a dish

C is the constant term.

Given that moving one mile away from the CBD x1i , the annual revenues will i will decrease by $60000. So, the coefficient of x1i, a is -60000

Given that increasing the average price of dish x2i by $1 , the annula revenue will i will increase by $40000. So the coefficient of x2i, b is 40000

The data shows  that the restaurant at the center of the CBD which means, x1i = 0 and giving away its food for free which means x2i = 0 is resulting in a loss of $20000. so the value of the constant term is c=20000.

so the multiple regression linear regression equation is:

i = -20000 + -60000*x1i + 40000*x2i

hence option A is correct

if the null hypothesis is rejected in hypothesis testing, no conclusions can be drawn from the test. the sample size has been too small. the alternative hypothesis is true. the data must have been accumulated incorrectly.

Answers

if the null hypothesis is rejected in hypothesis testing the alternative hypothesis is true.

The relationship between important factors of interest and any apparent connection, according to a competing theory, is most certainly not accidental. The opposite of a null hypothesis is an alternative hypothesis. If we are able to rule out the null hypothesis, it signifies that we have enough data to support the alternative hypothesis. In one test, we cannot rule out both possibilities.

If one is disproven, it indicates that there is evidence to support the other. The opposing view is that a study's potential conclusion will materialize. It claims there is no coincidence in the relationship between important components of interest and the observed connection. As a result, the alternative hypothesis is true if the null hypothesis is disproved during hypothesis testing.

The plane has a cruising speed of 200 miles per hour when there is no wind. at this speed, the plane flew 500 miles with the wind in the same amount of time it flew 300 miles against the wind.

We have to find the speed of the wind.

Time = Distance/speed

Time = 500/200 = 2.5hrs

When the plane moves against the wind its effective speed reduces as it has to overcome the opposing force of the wind since it is given that it cover's a distance of 300 miles at the same time we can write

2.5 = 300/ V(plane) - v(wind)

[tex]106=2(2w-7)+2w\\106=4w-14+2w\\106=-14+6w\\120=6w\\20=w\\\\l=2w-7\\l=2(20)-7\\l=40-7\\\\l=33[/tex]

One equation in a linear system is x + y = 1. Is it possible for the system to have a
solution of (0, 0)? (100, -49)? Explain your reasoning.

Answers

answer:

no, because 0+0≠1 and 100+-49≠1 so the values are not a part of the system.

step-by-step explanation:

for this question, plug in the x & y values into the equation x+y=1. if the values add up to be 1, then it's possible for the system to have those solutions. hope that helps!

The expression -5g + 15h - 25 can be simplified as -5(g + 3h - 5)

Expression

Expressions in math are mathematical statements that have a minimum of two terms containing numbers or variables, or both, connected by an operator in between. The mathematical operators can be of addition, subtraction, multiplication, or division. For example, x + y is an expression, where x and y are terms having an addition operator in between. In math, there are two types of expressions, numerical expressions - that contain only numbers; and algebraic expressions- that contain both numbers and variables.

In the question given, the expression is -5g + 15h - 25;

a study of whether or not customers respond to odors took place in a small pizza restaurant in france on two saturday evenings in may. on one of these evenings, a relaxing lavender odor was spread through the restaurant. on the other evening, no scent was used. the restaurant owners computed the mean amount spent on each night and computed a 95% confidence interval for the difference of means (lavender minus no odor) in euros to be (2.40, 4.82). can the researchers conclude there is a difference between the two means

Answers

The limits of the confidence interval are positive and don't include 0.

What is the confidence interval?

A confidence interval is a range of estimates for an unknown parameter in frequentist statistics. A confidence interval is calculated at a specified confidence level; the 95% confidence level is most commonly used, but other levels, such as 90% or 99%, are occasionally used.

Yes, there is a significant difference between the 2 means.

Since both the limits of the confidence interval are positive and

doesn't include 0.

Hence, the limits of the confidence interval are positive and don't include 0.

write the slope intercept form of the equation of the line through the given points with given slope

Answers

The equation of the line passing through the point (-1, -5) with slope = 6 is y = 6x - 1

The coordinates of the point = (-1, -5)

The slope of the line is the change in y coordinates with respect to the change in x coordinates of the line

The slope of the line m = 6

The slope intercept form is

y = mx + b

Where m is the slope of the line

b is the y intercept

Substitute the values in the slope intercept form

-5 = 6(-1) + b

-5 = -6 + b

b = -6+5

b = -1

The slope intercept form

y = 6x - 1

Therefore, the equation of the line is y = 6x - 1
