Answer:
Use inequalities.
At certain x values.
Step-by-step explanation:
The sample mean of the random sample is 50
The margin of error (E) is the amount of error allowed in the random sample.
The confidence interval (CI) is given by:
CI = μ ± E = (μ - E, μ + E)
Given a confidence interval of (38.02, 61.98), hence:
μ - E = 38.02 (1)
μ + E = 61.98 (2)
Hence solving equations 1 and 2 simultaneously gives:
μ = 50, E = 11.98
Hence the sample mean of the random sample is 50

Answer:
The correct option is the last diagram.
Step-by-step explanation:
The sign is greater than(>) which is represented with broken lines.
If you have 90 students going on a trip and have a budget, (including a fee), of $542.94 you can subtract the fee from this total to find how much each students ticket costs. $542.94 - $45.82 = $497.12 and then divide that by 90 students to determine the ticket cost. $497.12 / 90 = $5.52333… or $5.52 per ticket.
