QNT 501 EXAM 7.1. Solve for the unknown in the equation. 11A = 77 Divide both sides of the equation by the known factor to isolate the unknown value. 11 A 11 = 77 11 Now simplify. A= 7 Check. 11(7) = 77 77 = 77 Therefore, the solution of the equation is 7. 2. Solve for the unknown in the equation. B + 5 = 21 Subtract the known value from both sides of the equation to isolate the unknown value. B + 5 (5) = 21 (5) Now simplify. B = 16 Check. 16 + 5 = 21 21 = 21 Therefore, the solution of th...

QNT 561 FINAL EXAM Q&A.Set 1  A market researcher is interested in determining the average income for families in San Mateo County, California. To accomplish this, she takes a random sample of 300 families from the county and uses the data gathered from them to estimate the average income for families of the entire county. This process is an example of o Inferential statistics  If x is a binomial random variable with n=10 and p=0.8, what is the probability that x is equal to 4? o ...
