Answer:
0 = -54
Step-by-step explanation:
4(3x + 8) − 9 = 2(6x − 8) − 15
12x + 32 - 9 = 12x - 16 - 15
12x + 23 = 12x - 31
12x = 12x - 54
0 = -54

Answer:
30
Step-by-step explanation:
Given :
Mean, m = 30 metric tons
Standard deviation (s) = 1.5 metric ton
Sample size, n = 4
Since the impact force in the test model is normally distributed, the shape of the sampling distribution will also be approximately normal with a mean equal to the mean of the test model.
Hence, the sample mean impact force will be equal to the population mean.
Therefore, sample mean = 30 ; population mean = 30
