(a)
To predict the cost of attending the college in the 2016 − 2017 academic year.
(a)
Answer to Problem 3P
The cost of attending the college in the year 2016 − 2017 is
Explanation of Solution
Given information:
The equation of the line of best fit for the Average Tuition and fees at a Public College is:
Calculation:
Given,
Substitute 2016 for x
Simply the above equation.
Round to the nearest whole number.
We get,
∴The cost of attending a four − year public college in the 2016 − 2017 academic year is predicted to be about
(b)
To interpret slope of the line of best fit .
(b)
Explanation of Solution
Given information:
The equation of the line of best fit for the Average Tuition and fees at Public College is:
Formula Used:
An equation in the slope − intercept form is written as
Where m is the slope of the line and b is the y - intercept.
By comparing
Slope,
That is, rate of change of cost of attending the college is 409.43
That is, the cost of attending the college is increasing at a rate of 409.43

- 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
