Determine which of the following statements are true and which are false. (a) The equation 4x − sin (1)y + 2z = 3√5 is linear. (b) The equation xy + 4z = 4 is linear. (c) If a system of linear... more. Follows • 1. Expert Answers • 1. True Or False Linear Algebra Matrix Linear Transformation.
Demo H. asked • 01/21/22 A test consists of ten true/false questions. A student who forgot to study guesses randomly.
Since the true/false questions are independent of the multiple choice problems, you would multiply the two answers. So final answer would be (1/1024)*(1/1024) = (1/1024)^2 = 1/ (1024^2) = 1/ 1048576 Now to see this better, remember that probability problems can be much easier to understand when you look at the simplified version and then once ...
True or False Questions - Calculus State, with explanation, if the following statements are True or False. If f’(5) = 1.8 and g’(5) = 4.2 then f(x) + g(x) has slope 6 at x = 5
True or False: Exponents. What statement is always true for exponents? A negative base raised to the power of 2 has a negative value. Any number to the first power is zero.

Maria's final exam has true/false questions, worth 2 points each, and multiple choice questions, worth 3 points each. Let x be the number of true/false questions she gets correct, and let y be the number of multiple choice questions she gets correct. She needs more than 93 points on the exam to get an A in the class.
See tutors like this. The b statement is just the converse of the a statement, if you remember geometry. They are both TRUE. If limit of f (x) as x approaches a exists, then. lim x→a f (x) = L, where L is a finite number. lim x→a |f (x)| = |lim x→a f (x)| {Function of a limit = limit of the function; |.| is a function}
Matrix True and False Questions. a) If A and B are n x n matrices then (AB) 2 =A 2 B 2. b) If the product of two matrices AB is square, then A and B must be square. c) If A and B are matrices with sizes such that AB is square, then BA exists. d) If A and B are square matrices of the same size, then (AB) T = A T B T.
