Jim likes to day-trade on the Internet. On a good day, he averages a $1200 gain. On a bad day, he averages a $800 loss. Suppose that he has good days 25% of the time, bad days 55 % of the time, and the rest of the time he breaks even. What is the expected value for one day of Jim's day-
trading hobby?

go and ask your mom to you

d) 30 units^2

area of rectangle = l × b

we know,

length = 10 unit

breadth = 3 unit

applying the formula,

= l × b

= 10 × 3

= 30 unit^2

happy to

pls mark as brainliest

logv3(x+2)=1

rewrite in exponential form:

logb(x) = y is equal to b^y =x

b = 3, y = 1

now solve for x:

3^1 = x+2)

x = 3-2

x = 1

see the picture for the graph.
