Step-by-step explanation:
In a popular online role playing game, players can create detailed designs for their character's "costumes," or appearance. Fwam 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. 417 visitors purchased no costume. 63 visitors purchased exactly one costume. 7 visitors purchased more than one costume. Based on these results, express the probability that the next person will purchase no costume as a decimal to the nearest hundredth.
Answers
Answer:
0.86
Step-by-step explanation:
The probability that the next person will purchase no costume is 36%.
What is probability ?To express the probability that the next person will purchase no costume as a percent to the nearest whole number, we will use the total number of visitors to the website as the denominator and the number of visitors who purchased no costume as the numerator.
The total number of visitors to the website,
168 + 252 + 47 = 467
The number of visitors who purchased no costume = 168.
So, the probability that the next person will purchase no costume is:
168/467 = 0.360
0.3609 × 100
= 36.09
Rounding this to the nearest whole number, we get,
36%

Step-by-step explanation:
Slope of line passing through [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is given by,
m = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
From the graph attached,
Slope of the line passing through (-3, 0) and (0, 5) = [tex]\frac{5-0}{-3-0}[/tex]
= [tex]-\frac{5}{3}[/tex]
Line passing through a point (h, k) and slope 'm' will be,
y - h = m(x - k)
Since, line passing through (11, 0) is parallel to the line given in the graph,
Slope of the parallel line will be same as [tex]-\frac{5}{3}[/tex]
Equation of a line passing through (11, 0) and slope = [tex]-\frac{5}{3}[/tex]
y - 0 = [tex]-\frac{5}{3}(x-11)[/tex]
y = [tex]-\frac{5}{3}(x-11)[/tex]
Now satisfy this equation with the points given in the options,
Option (1)
For (1.67, -15.59),
-15.59 = [tex]-\frac{5}{3}(1.67-11)[/tex]
-15.59 = -15.55
False.
Therefore, given point doesn't lie on the line.
Option (2)
For (-0.33, -13.59)
-13.59 = [tex]-\frac{5}{3}(-0.33-11)[/tex]
-13.59 = -18.88
False
Option (3)
For (0.67, -18.59),
-18.59 = [tex]-\frac{5}{3}(0.67-11)[/tex]
-18.59 = 17.22
False
Option (4)
For (1.67, -15.59)
-15.59 = [tex]-\frac{5}{3}(1.67-11)[/tex]
-15.59 = -15.55
False.
Therefore, none of the points given in the options are lying on the line.

Answers
Answer:

Let the number of pages is xTim has read 30 % of a bookRemaining
100% - 30% = 70%70% of x is 0.7x
0.7x = 56x = 56/0.7x = 80 pagesAnswer:
[tex] \bf \huge 80 \: pages[/tex]
Step-by-step explanation:
Given that :Tim has read 30 % of a book.He has 56 more pages to finish.to find :How many pages are there in the book ?let us assume :total pages of book is 100•/•explanation :⟼ total book = 100•/•
⟼ Tim has read 30 % of a book.
⟼ 100 - 30 •/• = 70 •/•
⟼ 70 •/• = 56 pages
⟼ 1 •/• = 56 / 70
⟼ 100 •/• = 56 / 70 × 100
⟼ 100 •/• = 56 / 7 × 10
⟼ 100 •/• = 8 × 10
⟼ 100 •/• = 80 pages
∴ tim has 80 total pages in book.

A deli is offering two specials. The roast beef special gives a profit of $2.30 per sandwich, and the turkey special gives a profit of $3.10 per sandwich. The roast beef special uses two slices of bread and three slices of cheese. The turkey special uses two slices of bread and four slices of cheese. The deli has 120 slices of bread and 160 slices of cheese available for the specials. The deli wants to maximize its profit selling specials. Let x represent the number of roast beef specials and y represent the number of turkey specials. What are the constraints for the problem?
Answers
Answer:
The constraints are as follows;
1) 2·x + 2·y ≤ 120
2) 3·x + 4·y ≤ 160
3) x = 2.30
4) y = 3.10
5) P = 2.3·x + 3.10
Step-by-step explanation:
The question is a word problem, with the analysis as follows;
The profit from the roast beef special per sandwich = $2.30
The profit from the turkey special per sandwich = $3.10
The number of slices of bread in the roast beef special = Two slices
The number of slices of cheese in the roast beef special = Three slices
The number of slices of bread in the turkey special = Two slices
The number of slices of cheese in the turkey special = Four slices
The number of slices of bread the deli has = 120 slices
The number of slices of cheese the deli has = 160 slices
Let 'x' and represent the number of roast beef special and 'y' represent the number of turkey special the deli makes, then we have the constraints as follows;
For the number of slices of bread used;
2·x + 2·y ≤ 120...(1)
For the number of slices of cheese used;
3·x + 4·y ≤ 160...(2)
x = 2.30
y = 3.10
The profit 'P' is given by the following equation
P = 2.3·x + 3.10.

[tex] \displaystyle ( x_{1},y_{1}) = (0.82, - 3.18) \\ ( x_{2},y_{2}) = ( - 0.82, - 4.82)[/tex]
Step-by-step explanation:
we are given a system of quadratic and linear equation
we want to figure out x and y
in other words the coordinates where the linear function intercept quadrilateral function
to do so
you can use substitution method
since y equals to both equation so substitute:
[tex] \displaystyle {3x}^{2} + x - 6 = x - 4[/tex]
move right hand side expression to left hand side and change its sign so there's only 0 left on the left hand side:
[tex] \displaystyle {3x}^{2} + x - 6 - x + 4= 0[/tex]
simplify addition:
[tex] \displaystyle {3x}^{2} -2=0[/tex]
add 2 to both sides:
[tex] \displaystyle {3x}^{2} = 2[/tex]
divide both sides by 3
[tex] \displaystyle \frac{ {3x}^{2} }{3} = \frac{2}{3} [/tex]
[tex] \displaystyle {x}^{2} = \frac{2}{3} [/tex]
square root both sides:
[tex] \displaystyle {x} = \sqrt{\frac{2}{3} } \\ x = \frac{ \sqrt{2} }{ \sqrt{3} } [/tex]
rationalise the denominator by multiplying √3/√3:
[tex] \displaystyle x = \pm\frac{ \sqrt{6} }{3} = \pm0.82[/tex]
now let's figure out y
substitute the value of x to the linear equation:
[tex]y = \pm0.82 - 4[/tex]
when positive
[tex]y = - 3.18[/tex]
when negative
[tex]y = - 4.82[/tex]
Answer:
(x1,y1) = (0.82, - 3.18)
(x2,y2) = (-0.82, -4.82)
