Multi step problems what is -10(10+b)=5(3b+5)

Mathematics
1 answer:
Alla [95]2 years ago
5 0

Answer:

b= -5

Step-by-step explanation:

-10(10+b)=5(3b+5)

Distribute

-100 -10b = 15b +25

Add 10b to each side

-100-10b+10b = 15b+10b +25

-100 = 25b+25

Subtract 25 from each side

-100-25 = 25b+25-25

-125 = 25b

Divide by 25

-125/25 =25b/25

-5 =b

Darren has the option of investing in either Stock A or Stock B. The probability of the return of Stock A being 25% is 0.45, 14%
Lunna [17]

Answer:

C)A is 15.95% ,B is 11.85%

Step-by-step explanation:

We know that the expected value in probability distribution is given as

Lets X is the expected value then

X= \sum_{i=1}^{i=n} X_i P_i

For stock A

X=0.25 x 0.45+0.14 x 0.25+0.04 x 0.3

X=0.1595

So the expected return for A is 15.95%

For stock 9

X=0.3 x 0.3+0.09 x 0.25+0.02 x 0.3

X=0.1185

So the expected return for B is 11.85%

So our option C will be the answer of that problem.
