Answer to Problem 10PPE
Scatter plot of the data given is shown below:
It shows trend line and equation of this tread line is
Explanation of Solution
Given information: The below table shows the data related to average price and number sold.
Years | 1990 | 1992 | 1994 | 1996 | 1998 | 2000 | 2002 | 2004 | 2006 |
Revenue | 5.7 | 6.5 | 7.0 | 7.9 | 8.7 | 9.6 | 9.9 | 10.8 | 11.5 |
Concept used: In XY coordinate plane, years is represented on horizontal x axis and revenue ( in billions dollars) is represented on vertical y axis..
Calculation: Two data sets, on plotting in XY plane, show the related scattered plot as:
And as in year 2004, attendance is 328 and in 2006, it is 335, so estimated attendance in year 2005 will be 330 million.
Conclusion: Scatter plot shows that there is a strong

- Thank you.arrow_forwardThank you.arrow_forwardLet V, W, and Y be vector spaces. Suppose dim(V) dim(W) = dim(Y) = 2. = Let ("beta") be an ordered basis for V. Let ("gamma") be an ordered basis for W. Let ("zeta") be an ordered basis for Y. Suppose S is a linear transformation from V to W and that T is a linear trans- formation from W to Y. Remember that ToS is the function from V to Y defined by (TOS)(v) = T(S(v)). (a) Prove that To S is a linear transformation. (b) Prove that ° [T • S] = [T]{[S]}.arrow_forward
- Let W={(0, a, 0) | a Є R}. (a) List four elements from W. (b) Determine whether W is a subspace of R³, and prove that your answer is correct.arrow_forwardFor this problem, refer to the network as shown in Figure 1, answer the following questions. B A C FIGURE 1. For Problem (7). Let x₁ be the number of users at website A. Let x2 be the number of users at website B. Let x3 be the number of users at website C. Assume that there are a total of 900 users at these three websites. This gives us the following system of linear equations: x1 = x2 + 1x3 x2 = x1 + x3 x3 = x2 = 900 x1 + x2 + x3 = (a) Put this system into a standard form (with all variables on the left side and with the constants on the right), and convert that system into an augmented matrix, and then... (b) Use elementary row operations to put the augmented matrix into reduced row echelon form, and then... (c) Write down the solution space for this system of equations, and then... (d) Identify which website(s) would be ranked most highly by PageRank.arrow_forward4 2 Let C = -6 -3 (a) Find det(C). (b) Use your answer for (a) to determine whether C is invertible.arrow_forward
