Tan(angle) = Opposite Leg / adjacent leg
tan(37) = x / 10
x = 10 *tan(37)
x = 7.5
Answer:
a) 0.923
b) 0.957
c) 0.88
d) 0.077
Step-by-step explanation:
We are given the following information in the question:
Mean, μ = 40
Standard Deviation, σ = 14
We are given that the distribution of number of milligrams of porphyritic per deciliter of blood is a bell shaped distribution that is a normal distribution.
Formula:
a) P(xis less than 60)
P(x < 60)
Calculation the value from standard normal z table, we have,
b) P(x is greater than 16)
Calculating the value from the standard normal table we have,
c)P(x is between 16 and 60)
d) P(x is more than 60)
P(x > 60) = 1 - P(x < 60) = 1 - 0.923 = 0.077
Mean = Arithmetic Average. Average = add the numbers and dividing by how many numbers there are. So,
711+533+664/3 = 1908/3 = 636
The mean weight is 636.
