Answer:
Step-by-step explanation:
I think the median you are asking is the middle value,
because there is a total of 20 vehicles, there are two middle number: 31 and 31.
To solve this:
you first plus these two numbers together, you will get 62.
then divide them by 2, then you will get the middle number.
the middle number will be 31. ( actually because theese two number are the same, you do not really need to plus them then divide by 2, you could just answer the question 31, but because when you do other question and has the same situation but not the same number, (suppose you got 20 and 21) Then you need to do this question like I said above)
I wish this could help you.
Answer:
(P+9s+21)/3
Step-by-step explanation:
hello :
P/3 + (3s + 7) = P/3 + 3(3s + 7)/3 = (P+9s+21)/3
First: the homogeneous solutions: the characteristic equation is4r^2 - 4r - 3 = 0which has roots r = 3/2, -1/2 hence the homogeneous solution isy = c1.exp(-x/2) + c2.exp(3x/2)
next you need the general form for the guess for yp and that isyp = A1cos(2x) + A2sin(2x)
Now substitute that into the equation and solve for A1, A2.
Answer:
Solution is 34
Step-by-step explanation:
to find f(8) you plug in 8 for x in the equation
f(x)=4(8)+2=34
hope this helps.
First distribute and then combine like terms, answer: -1.42x+2.8
