2/3(6x+12) = -24 can be simplified to
4x+8 = -24 so the first answer is right and if you further simplify it by subtracting the 8 you get
4x = -32
Which is the other right answer.
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:
switchy switchy
Step-by-step explanation:
sin 15 = 38/x
We need to switch the sin15 and the x by multiplying both sides by x and dividing both sides by sin 15
x = 38/sin 15
