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: Graph 3
Explanation: Because the parabola goes down so the vertex must be the maximum point and it's coordination is (1,3)
Answer:

Step-by-step explanation:
In order to find the measure of angle KMI, we need to note some angle relationships here.
GK and HJ are parallel lines cut by a transversal, meaning the angles formed by this transversal line will be the same along the parallel lines.
We know that the 29° angle is an alternate interior angle to KMI. This means their angle measures are the same.
Therefore, KMI is also 29°.
Hope this helped!
