Area of big rectangle =8x7=56cm²
area of small rectangle =5x4=20cm²
hence area of shaded region=56-20=36cm²
By definition
... sec(θ) = 1/cos(θ) . . . . trig identity
... sec(θ) = 1/(9/10) . . . . substitute the given value, then simplify to ...
... sec(θ) = 10/9
Answer:
The expected value is also known as the expectation, mathematical expectation, mean, average, or first moment.
Answer:
μ = 1.3468
Step-by-step explanation:
Given data:
Observations
0.85
0.88
0.88
1.06
1.09
1.12
1.29
1.31
1.42
1.49
1.59
1.62
1.65
1.71
1.76
1.83
sum of the observations = 21.55
now,
the total number of the given data, n = 16
now, the mean is given as:
Mean = (Sum of all the observation) / (Total number of observations)
on substituting the values in the above formula, we get
Mean = 21.55 / 16
or
Mean = 1.3468
Since, it is given that the data follows normal distribution.
thus, the normal mean can be used as the point of estimator (μ)
i.e μ = 1.3468
