By definition, an expression does not contain AN EQUALS SIGN (=).
Step-by-step explanation:
Slope: −2
y-intercept: (0,1)
Answer:
Sec^2 x - 1 = tan^2x
Proof:
Sec^2x = 1+ tan^2x
1/cos^2x = 1 + sin^2x/cos^2x
<span>1/cos^2x - sin^2x/cos^2x = 1
</span>Using common denominator:
(1-sin^2x)/cos^2x = 1
sin^2x + cos^2 x = 1
cos^2 x = 1 - sin^2x
Substituting :
cos^2x/<span>cos^2x = 1
</span>1 = 1
Left hand side = right hand side
The answer is 44%.!!!!!!!!!!!!!!!!!!!!!!!!!!!
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

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.
