Sedbober [7]

Answer: 0.8313

Step-by-step explanation:

As per given we have,

$\mu=15.5$ $\sigma= 3.6$

Also, the distribution of the number of suitcases that get lost each week on a certain route is approximately normal.

Since , $z=\dfrac{x-\mu}{\sigma}$

z-score corresponds to x= 10: $z=\dfrac{10-15.5}{3.6}\approx-1.53$

z-score corresponds to x= 20: $z=\dfrac{20-15.5}{3.6}=1.25$

P-value = $P(10$

$=P(z$

Hence, the probability that during a given week the airline will lose between 10 and 20 suitcases = 0.8313

Suppose A,B and C are 2 ×2 matrices , E,F and G are 3 × 3 matrices, H and K are 2×3 matrices and L and M are 3×2 matrices. For e

Alekssandra [29.7K]

Answer:

a) 2x2 b)3x3 c) Not possible d) 2x3 e) 3x2 f) 3x3 g)Not possible h)3x2

Step-by-step explanation:

-> we can only add matrices with same size

-> we can only multiply when columns of first equal to rows of second

-> nxm multiplied by pxq gives nxq eg 3x2 mul 2x2 gives 3x2

-> addition and mul by const number dont change the size

So considering the above facts :-

a) AB+C = [(2x2)(2X2)]+(2x2)=(2x2)+(2x2)=2x2

b) 3GF =3[(3x3)(3x3)]=3(3x3)=3x3

c)CK+B= [(2x2)(2x3)]+(2x2)=(2x3)+(2x2) which is not possible (see point 1)

d)CK+H =as CK is (2x3) so (2x3)+(2x3)=(2x3)

e)EMC=[(3x3)(3x2)](2x2)=(3x2)(2x2)=3x3

f)GLH=[(3x3)(3x2)](2x3)=(3x2)(2x3)=3x3

g)HLG=[(2x3)(3x2)](3x3)=(2x2)(3x3)= not possible(see point 2)

h)2EL+5MB=2[(3x3)(3x2)]+5[(3x2)(2x2)]=(3x2)+(3x2)=3x2
