In a popular online role playing game, players can create detailed designs for their character's "costumes," or appearance. Scarlett sets up a website where players can buy and sell these costumes online. Information about the number of people who visited the website and the number of costumes purchased in a single day is listed below. 236 visitors purchased no costume. 202 visitors purchased exactly one costume. 40 visitors purchased more than one costume. Based on these results, express the probability that the next person will purchase no more than one costume as a fraction in simplest form.

Answers

Answer:

The probability that the next person will purchase no more than one costume [tex]\frac{219}{239}[/tex].

Step-by-step explanation:

The data for a single day is s follows:

236 visitors purchased no costume. 202 visitors purchased exactly one costume. 40 visitors purchased more than one costume.

The total number of customers is, N = 236 + 202 + 40 = 478.

Let X denote the number of costumes purchased by the next person.

Compute the probability that the next person will purchase no more than one costume as follows:

[tex]P (X\leq 1)=1-P(X>1)[/tex]

               [tex]=1-\frac{40}{478}\\\\=\frac{478-40}{478}\\\\=\frac{438}{478}\\\\=\frac{219}{239}[/tex]

Thus, the probability that the next person will purchase no more than one costume [tex]\frac{219}{239}[/tex].

Small- 12 oz for $3.95

Medium 16 oz for 4.25$

Large - 20oz for $4.55

Answers

Answer:

medium

Step-by-step explanation:

yea sure so according to my calculations small is 3.95 so if we subtract the medium size minus 3.95 which would be 4.25-3.95 the difference is 30 cents now if we subtract large size by small size 4.55-3.95 the difference is .60 cents therefore if she wants to save .60 cents i would choose medium size but large minus medium 4.55-4.25 it would also be .30 cents

40 POINTS- Are a logistic equation and a logistic regression model the same thing? If not, what's the difference?
I have a logistic equation and need to make a logistic regression model from it but I'm not sure how to. Any help is appreciated :)

Answers

Answer: They are diffrent

Step-by-step explanation: The logistic equation was first published by Pierre Verhulst in 1845. This differential equation can be coupled with the initial condition P(0) = P0 to form an initial-value problem for P(t). Suppose that the initial population is small relative to the carrying capacity. Then P K is small, possibly close to zero.

The logistic regression coefficients are the coefficients b 0, b 1, b 2,... b k of the regression equation: An independent variable with a regression coefficient not significantly different from 0 (P>0.05) can be removed from the regression model (press function key F7 to repeat the logistic regression procedure).

Answers

Answer:

No

In the first week of​ July, a record 1,060 people went to the local swimming pool. In the second​ week, 100 fewer people went to the pool than in the first week. In the third​ week, 140 more people went to the pool than in the second week. In the fourth​ week,146 fewer people went to the pool than in the third week. What is the percent decrease in the number of people who went to the pool over these four​ weeks?

Answers

Answer: 10%

Step-by-step explanation:

As per given ,

Initial number of people went to pool = 1060

After 4 weeks periods, number of people went to pool = 1060 - 100 +140 -146  ['+' for addition . '-' for decrease]

= 954

The percent decrease in the number of people who went to the pool over these four​ weeks = [tex]\dfrac{1060-954}{1060}\times 100[/tex]

[tex]=\dfrac{106}{1060}\times100\\\\=10\%[/tex]

Hence, the percent decrease in the number of people who went to the pool over these four​ weeks = 10%
