Question
Chapter 7, Problem 1SE
To determine
To decide: if the given statement is true or false.
Expert Solution & Answer

Answer to Problem 1SE
True.
Explanation of Solution
Given information:
The statement, “If A is orthogonally diagonalizable, then A is symmetric.”
Theorem Used:
An
The given statement is true.
By the above theorem, it is clear that since the matrix A is orthogonally diagonalizable, so it must also be symmetric.
Hence, given statement is true.

Amy and Samiha have a hat that contains two playing cards, one ace and one king. They are playing a game where they randomly pick a card out of the hat four times, with replacement.
Amy thinks that the probability of getting exactly two aces in four picks is equal to the probability of not getting exactly two aces in four picks. Samiha disagrees. She thinks that the probability of not getting exactly two aces is greater.
The sample space of possible outcomes is listed below. A represents an ace, and K represents a king. Who is correct?
Consider the exponential function f(x) = 12x. Complete the sentences about the key features of the graph.
The domain is all real numbers.
The range is y> 0.
The equation of the asymptote is y = 0
The y-intercept is 1
