Explanation Given that, the equation is e = T 1 r γ r − T 2 r γ r − T 1 + T 2 T 1 r γ r − T 2 r γ r . Consider the expression T 1 r γ r − T 2 r γ r − T 1 + T 2 T 1 r γ r − T 2 r γ r . Simplify the expression as follows. T 1 r γ r − T 2 r γ r − T 1 + T 2 T 1 r γ r − T 2 r γ r = ( r γ r ) ( T 1 − T 2 ) − T 1 + T 2 ( r γ r ) ( T 1 − T 2 ) ( Take the common term r γ r ) = ( r γ r ) ( T 1 − T 2 ) − 1 ( T 1 − T 2 ) ( r γ r ) ( T 1 − T 2 ) ( Take the common term − 1 ) = ( T 1 − T 2 ) ( r γ r − 1 ) ( r γ r ) ( T 1 − T 2 ) ( Take the common term ( T 1 − T 2 ) ) Simplify further as follows

Consider the following statement: For all integers a and b, if a 0 (mod 6) and b #0 (mod 6), then ab #0 (mod 6). Which of the following statements are true? (select all that apply) Original statement ✓ Contrapositive Converse Negation ☐ None of the statements are true

Proposition: If m is an odd integer, then m + 6 is an odd integer. Proof: For m + 6 to be an odd integer, there must exist an integer n such that m+6=2n+1. Subtracting 6 from both sides, we see that m = 2n+1-6 = = 2n― 6+1 = 2(n − 3) + 1. Since the integers are closed under subtraction, then n-3 € Z. Hence, the last equation implies that m = = 2q+1 where q = n = 3. This proves - that if m is an odd integer, then m + 6 is an odd integer. Based upon the Reading assignment and the Elements of Style >>, which of the following is the most significant error in the proof? The proof does not use complete sentences The proof contains a sentence that begins with a mathematical symbol The proof uses cumbersome notation The proof contains a variable used for more than one object The proof is written backwards The proof uses an example to prove the general case

Suppose that you want to estimate the mean monthly gross income of all households in your local community. You decide to estimate this population parameter by calling 150 randomly selected residents and asking each individual to report the household’s monthly income. Assume that you use the local phone directory as the frame in selecting the households to be included in your sample. What are some possible sources of error that might arise in your effort to estimate the population mean?
