Answer:
P (X = i) = (i + 9 _ 9) (1/2)^(i + 10)
Step-by-step explanation:
Range of X = {0, 1, 2, 3......10}
P (X = i) = P (NB (10, ½) i = 10)
P (X = i) = (i + 9 _ 9) (1/2)^10 (1/2)^(1+10-10)
P (X = i) = (i + 9 _ 9) (1/2)^10 (1/2)^1
P (X = i) = (i + 9 _ 9) (1/2)^(i + 10)

PLEASE HELP! Determine the slope and the y-intercept of the table.
To find the slope, use two (or three) points and plug them into y2 - y1/ x2 - x1.
Once you have the slope, plug one point and the slope into . . .yup, point-slope form. y-y₁=m(x-x₁)
After doing this, you will have the slope and the y-intercept.

What is an expression?An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example: 2 + 3x + 4y = 7 is an expression.
We have,
20, 15, 50, 85, 75, 60
The range is the difference between the highest value and the lowest values in the given set of numbers.
Now,
The lowest value is 15
The highest value is 85
Range = 85 - 15 = 70
Midrange = 70/2 = 35
Thus,
The range of the set of numbers is 70
The midrange of the set of numbers is 35

Ben and Joel are raising money for their class trip by selling wrapping paper. Ben raised $43.50 by selling 12 rolls of solid paper and 9 rolls of printed paper. Joel raised $51.50 by selling 8 rolls of solid paper and 15 rolls of printed paper. Find the cost of each type of wrapping paper.
Answer:
Solid paper costs 1.75 each
Printed paper costs 2.50 each
Step-by-step explanation:
Given:
Ben = $43.50 (12 rolls solid paper and 9 rolls of printed paper)
Joel = $51.50 (8 rolls solid paper and 15 rolls of printed paper)
Let x = solid paper
Let y = printed paper
12x + 9y = 43.50
8x + 15y = 51.50
Find x:
8x + 15y = 51.50
8x = 51.50 - 15y
x = (51.50 - 15y)/8
Substitute x:
12x + 9y = 43.50
12(51.50 - 15y)/8 + 9y = 43.50
(618 - 180y)/8 + 9y = 43.50
8 (618 - 180y)/8 + 8*9y = 43.50 * 8
618 - 180y + 72y = 348
-108y = 348 - 618
-108y = -270
-108y/-108 = -270/-108
y = 2.50
x = (51.50 - 15y)/8
x = (51.50 - 15(2.5) /8
x = (51.50 - 37.50)/8
x = 14/8
x = 1.75
To check: x = 1.75 ; y = 2.5
12x + 9y = 43.50
12(1.75) + 9(2.5) = 43.50
21 + 22.50 = 43.50
43.50 = 43.50
8x + 15y = 51.50
8(1.75) + 15(2.5) = 51.50
14 + 37.50 = 51.50
51.50 = 51.50

A local hamburger shop sold a combined total of 762 hamburgers and cheeseburgers on Friday. There were 62 more cheeseburgers sold than hamburgers. How many hamburgers were sold on Friday?
Answer:
Step-by-step explanation:
We have to come up with a system of equations in order to solve this because we have 2 unknowns: hamburgers and cheeseburgers. h is hamburgers and c is cheeseburgers. We know that both of these together totaled 762, so
h + c = 762
We also know that more cheeseburgers were sold than were hamburgers. 62 more cheeseburgers, to be exact. So the second equation is
c = h + 62.
Now we will sub that second equation into the first one and solve for h:
h + c = 762 becomes
h + h + 62 = 762 and
2h + 62 = 762 and
2h = 700 so
h = 350. So 350 hamburgers were sold and 762 - 350 is the number of cheeseburgers. 412 to be exact.

I will give brainliest if you are correct
Answer:
C
Step-by-step explanation:
to be a linear function the change in X and the change in Y has to be the same hence slope
A. x changes by+ 1 see 2,3,4,5, and y changes by +5, +7, +9 so A is not a linear function
B. X changes by -1 in all, y changes +1 for first 3 then -1 last, so B is not a linear function
C. X changes by +1 for all and y changes by -6 for all so is it is a linear function
D x changes by +1 for all and y changes by -1, +1, +3 so no linear fn.

g(n) = 2n + 5; find g(-1)
Answer:
Solving g(n)=2n+5 by putting n=-1 we get g(-1)=3
Step-by-step explanation:
We are given g(n)=2n+5
We need to find g(-1)
For finding g(-1) put n=-1 in g(n)=2n+5
[tex]g(n)=2n+5\\Put \ n=-1\\g(-1)= 2(-1)+5\\g(-1)=-2+5\\g(-1)=3[/tex]
So, Solving g(n)=2n+5 by putting n=-1 we get g(-1)=3

What are some rules of transformations?Suppose we have a function f(x).
f(x) ± d = Vertical upshift/downshift by d units (x, y ±d).
f(x ± c) = Horizontal left/right shift by c units (x - + c, y).
(a)f(x) = Vertical stretch for a > 0, vertical shrink a < 0. (x, ay).
f(bx) = Horizonatal compression b > 0, horizontal stretch for b < 0. (bx , y).
f(-x) = Reflection over y axis, (-x, y).
-f(x) = Reflection over x-axis, (x, -y).
Given, A function y = (x + 2)² and it is translated to y = x² + 3.
Now, The part x² from (x + 2)² is translated 2 units to the left, and the part
+ 3 is translated up by 3 units.
