Step-by-step explanation:
To calculate the weighted moving average for period 13 with weights 0.4 and 0.3.
P13 = (30.7x 0.4) + (42.0x 0.3)
P13 = 12.28 + 12.60
P13 = 24.88

Step-by-step explanation:
While working at his neighborhood math tutoring center researching the comprehension level of the students Dion investigated that the distribution of the student test scores are normally distributed with a mean of 79.13 and a standard deviation of 6.34. What is the probability that the student scores less than 60.11
We solve using z score formula
z = (x-μ)/σ, where x is the raw score, μ is the population mean, and σ is the population standard deviation.
z = 60.11 - 79.13/6.34
Answer:
It says double, so it means that:
