In a NiCd battery, a fully charged cell is composed of nickelic hydroxide. Nickel is an element that has multiple oxidation states. Assume the following proportions of the states:

X 0 2 3 4
p(X) p 0.23 0.35 0.20

(a) The missing probability p is equal to?

The missing probability p = 0.22.

Step-by-step explanation:

A fully charged cell is composed of nickelic hydroxide in a NiCd battery.

Nickel is known to be such an element that it has multiple oxidation states.

The proportions of the states are given as following.                                          

                   X                                   p(X)

                   0                                    p

                   2                                    0.23

                   3                                    0.35

                   4                                    0.2

The total probability of an event, which in this case, is the event that Nickel has oxidation states of either 0, 2 , 3 or 4, is always equal to 1.

Therefore we can write p + 0.23 + 0.35 + 0.2  = 1

Therefore  p = 1 - (0.23 + 0.35 + 0.2) = 1 - 0.78 = 0.22

The missing probability p = 0.22.

boxplot e is the answer

the length of o'p' is .

step-by-step explanation:

it is given that the quadrilateral m'n'o'p' is the image of quadrilateral mnop after dilation.

the center of dilation is origin and the scale factor is 1.5.

in dilation the image and preimge are similar figures. it means the sides of image and preimage are proportional.

the scale factor is defined as

the scale factor is 1.5.

multiply both sides by op.

note: if the value of op is given, then multiply the value of op with 1.5 to get the length of side o'p'.

therefore length of o'p' is .
