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).

Is it necessary to have a common denominator when you multiply two fractions? Explain.
Answers
Answer:
No
Step-by-step explanation:
Multiplying fractions does not require that the fractions have the same denominator. Instead, the numerators are multiplied with each other and the denominators are multiplied with each other. However, the resulting fraction may not be in lowest terms so it may need to be reduced.

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%

Answer: A
Step-by-step explanation:
We need to convert each city to percentage. Los Angeles is 13/50 and we can double that to convert it to a percentage of 26%. Next is Seattle which is 3/10 and we can multiply that by 10 to get a percentage of 30%. Next is San Francisco, which is at 2/5 and we multiply that by 20 to get a percentage of 40%. Next is Boston which is 43%. The final city is New York City which is 48%. The order of these cities in least to greatest in percentage of public transport use is Los Angeles, Seattle, San Francisco, Boston, and New York City. Therefore the answer is A.

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

ABCD is a rhombus.
Find each angle.
Reason:
Plz answer ASAP, thank you
Answers
Answer:
Step-by-step explanation:
I sympathize. The question is not very clear: you don't know what A and B really are (I mean which vertex).
However it is a rhombus, and you are to assume that B follows A. So put A anywhere and make B follow it. They are supplementary which means they add to 180 degrees. All rhombi have that property.
A + B = 180
A/B = 2/1
Cross Multiply the second equation
A = 2*B
Put 2B into the first equation.
2B + B = 180 Combine the left terms
3B = 180 Divide both sides of the equation by 3
B = 180 / 3
B = 60
B = 60
A = 180 - 60 = 120
Label the two acute angles as 60 and the two obtuse angles as 120.
Acute: means less than 90
Obtuse: means more than 90

two boats leave a ramp traveling in opposite directions. The second boat is 10 miles per hour faster than the first. After 3 hours they are 150 miles apart. Find the speeds of the boats.
Answers
Answer:
220 mph ; 230 mph
Step-by-step explanation:
Given that :
Speed of First boat = x
Speed of Second boat = y
y = (10 + x) mph
Distance apart after 3 hours = 150 miles
Speed of the boats :
Speed / time = distance
First boat distance = x / 3
Second boat distance = (10+x) /3
x/3 + (10+x)/3 = 150
x + 10 + x = 150 * 3
2x + 10 = 450
2x = 450 - 10
2x = 440
x = 220 mph
Speed of second boat = 220 + 10 = 230 mph

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].
