A stock has a 25% probability of increasing by $10 and a 75% probability of decreasing by $5. What is the stocks expected increase or decrease?

Please help me!!

The stocks expected decrease is of $1.25.

Step-by-step explanation:

To find the expected change, we multiply each change by it's probability.

We have that:

There is a 25% probability of increasing by $10.

There is a 75% probability of decreasing by $5(that is, 75% probability of the value being -5).

What is the stocks expected increase or decrease?

0.25*10 - 0.75*5 = -1.25

Negative, so a decrease.

The stocks expected decrease is of $1.25.

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 .
