Answer:
So the price of house 0f house after n number of year = 380,200 - 11800n
Step-by-step explanation:
Bob has a bought a new house for $380,200. He estimates the value of the house after each year and he also assumes that the value of the house decreases by the same amount each year.
So to find the equation to define the value of the house after each year, we have to find out how much depreciation happens for the value of the house in each year.
Final value = $321,200
Depreciation each year =
= $11,800
So the price of house 0f house after n number of year = 380,200 - 11800n
Answer:
The coefficients are therefore
1,1
1,2,1
1,3,3,1
1,4,6,4,1
1,5,10,10,5,1
1,6,15,20,15,6,1
1,7,21,35,35,21,7,1
Step-by-step explanation:
(a+b)^n
=a^n+na^(n-1)b+(n(n-1)/2)a^(n-2)b²+...+nab^(n-1)+b^n
=C(n,0)a^n+C(n,1)a^(n-1)b+C(n-2)a^(n-2)b^sup2;.....C(n,n)b^n
For n=1
(a+b)1=a+b
(a+b)2=a²+2ab+b^sup2;
(a+b)3=a³+3a^sup2;b+3ab²+b³
...
The coefficients are therefore
1,1
1,2,1
1,3,3,1
1,4,6,4,1
1,5,10,10,5,1
1,6,15,20,15,6,1
1,7,21,35,35,21,7,1

This is the Pascal's triangle
The sum of each pair of adjacent numbers gives rise to a number on the next line.
This also means that
(a+b)7
=a^7+7a^6b+21a^5b²+35a^4b³+....+7ab^6+b^7 ............(A)
which is almost the solution to the problem.
To solve the problem using the Pascal's triangle, substitute a=x, and b=2y in equation (A) to give the expression of the final answer.
Answer:
I'll give you the answers to the ones I know
I tried my best. Sorry if it took a long flippin time.
Theoretical probability is what you think will happen or what is expected to happen. So B) (Theoretical probability) goes to number 7.
Experimental probability is what happens after you test something. so C) (Experimental probability) is 6.
Probability = the number of ways of achieving success. the total number of possible outcomes. so A) (Probability) would be 3.
An outcome of a probability experiment is one possible end result. The total outcomes are the total number of possible outcomes for the probability experiment not sure what this would be but hope that gives you an understanding.
Sample space is all the possible outcomes of an event. E (Sample Space) is 2.
In probability theory, an event is a set of outcomes of an experiment. F (Event) would be 1.
Also for the last one I don't know what that is at all but hope this helps (:
Answer: p= 25n/7 358
n will be the total number of students on the field trip
g could represent the number of groups
p will represent the number of pencils
For this situation with 100 students, John will need 358 pencils. for 14 2/7 groups.
To be safe, since he has a partial group, he should round up to 15 groups and get 375 pencils. Especially if the pencils only come in boxes of 25, and he can't buy a partial box.
Step-by-step explanation:
25g = p
g =n/7
Combine these to get the ratio
g becomes unnecessary
p= 25n/7
the exact calculation for g was 100/7 = 14.28571
The exact calculation for p = 100/7 × 25 = 357.142857
But you can't buy partial pencils!
