Answer: (5,8)
Step-by-step explanation:
So this is a matter of using a system of linear equations
To start if a total of 13 people got a ticket then we know that
x+y=13
x and y being explained in the problem
then if adult tickets are $40 and children tickets are $20 and the total cost is 360 we can set up the next equation
40x+20y=360
If you were to plug in 1 lets say into x that means that 1 person bought a ticket for $40 this shown by 40 (1) this is the same premise for the childrens tickets.
now we have
x+y=13
40x+20y=360
now we can solve by eliminating one of the variables this is done by either getting rid of the x or y and solving for the other. I solved for the y value first this looks like
-40(x+y=13)
40x+20y=360
Distribute the -40 to each value
giving you
-40x-40y=-520
40x+20y=360
add these together from the top down
the x's cancel leaving
-20y=-160
then isolate the y value by dividing both sides by -20
-20y/-20=-160/-20
leaving you with your y point
y=8
This is how many childrens rickets were sold now we can plug into the first linear equation
x+8=13
now easy subtration to isolate the x point
x+8-8=13-8
x=5
Finally leaving you with point (5,8)

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).

Rewrite y+3=−(x−5) in standard form .
Answers
Answer:
x + y = 2
Step-by-step explanation:
The equation of a line in standard form is
Ax + By = C ( A is a positive integer and B, C are integers )
Given
y + 3 = - (x - 5) ← distribute
y + 3 = - x + 5 ( subtract 3 from both sides )
y = - x + 2 ( add x to both sides )
x + y = 2 ← in standard form

can someone solve a - 3 over 7 s = -8
and a + 24 = -15
STEP BY STEP PLEASE.
Answers
Answer:
a=-39; s=0.75
Step-by-step explanation:
Solve the System of Equations by Substitution.
First, solve one of the equations for a variable. I'll do the 2nd one because it only has one variable.
a+24=-15 -------> a=-39
Now we know what a is just plug it back into the other equation and get s.
[tex]\frac{a-3}{7s} =-8[/tex]
[tex]\frac{-39-3}{7s} =-8[/tex]
[tex]\frac{-42}{7s} =-8[/tex]
Switch the -8 and 7s
[tex]\frac{-42}{-8} =7s[/tex]
Simplify the fraction
5.25=7s
Divide by 7 to isolate the s
0.75=s
Answer:
2)a+24=-15
a=-15-24
a=-39

Work out 5.9 + 3.172
Answers
Answer:
9.072
Step-by-step explanation:
Answer:
9.072
Step-by-step explanation:
For this problem, we will simply use the property of 0 and addition to accumulate a sum.
Note, any digit not shown to the right of a decimal can be written with a zero. So 5.9 can be rewritten as 5.900.
Let's perform the addition.
5.900
+ 3.172
-----------
9.072
Using the idea of zeros to the right of the decimal, we are able to trivially complete this sum.
Hence, the answer is 9.072.
Cheers.

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

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].
