Answer:

Mean =\sum x P(x) = 36.86

Standard deviation =\sum x^2P(X)=1360.9

Step-by-step explanation:

x          P(x) x \times P(x)       x^2 \times  P(x)

33         0.02     0.66          21.78

34          0.06     2.04         69.36

35           0.1      3.5        122.5

36           0.2      7.2         259.2

37           0.24     8.88        328.56

38           0.26     9.88        375.44

39            0.1     3.9         152.1

40            0.02     0.8         32

             1        36.86      1360.9

We are supposed to find mean and standard deviation

Mean =\sum x P(x) = 36.86

Standard deviation =\sum x^2P(X)=1360.9

loris [4]

Answer:

The complex number r = -14 - i\,5 belongs to the third quadrant of the complex plane.

Step-by-step explanation:

Let be r = -14 - i\,5. In the complex plane, if \Re (r) < 0 (real component) and \Im (r) < 0 (imaginary component), the number belongs to the third quadrant of the complex plane. The complex number r = -14 - i\,5 belongs to the third quadrant of the complex plane.
