P(CIY)=[P((C and Y)]/P(Y)
P(C)=40/146=20/73
P(Y)=30/146=15/73
Thus:
P(C and Y)=15/146=
Hence:
P(CIY)=(15/146)/(15/73)=1/2
Answer:
24
Step-by-step explanation:
To find f(#) or g(#), plug the number into each x of the equation.
f(x) = -x + 5
f(2) = -(2) + 5
Simplify the parentheses by multiplying.
f(2) = -2 + 5
Add.
f(2) = 3
g(x) = 3x + 2
g(2) = 3(2) + 2
Simplify the parentheses by multiplying.
g(2) = 6 + 2
Add.
g(2) = 8
Now they are asking you to multiply
f(2) • g(2)
3 • 8
= 24
Hope this helps!
ANSWER:
f(x)⁻¹ = (x+10)/2
WORKING OUT:
f(x) = 2x - 10
y = 2x - 10
*Replace all 'y' values with 'x' and vice versa*
x = 2y - 10
*Make y the subject of the equation*
2y = x+10
y = (x+10)/2

Answer:
11.84% approx.
Step-by-step explanation:
Expected return = Respective return × Respective probabilities
= (18.5 × 0.71) + (-7.6 × 0.29)
= 10.931%
Probability Return Probability ×(Return - expected return)²
0.71 18.5 0.71×(18.5 - 10.931)² = 40.67573
0.29 -7.6 0.29×(-7.6 - 10.931)² = 99.585409
Total = 140.261139%
![SD=[\frac{\text{total probability(return-expected return)}^2}{\text{total probability}}]^{(\frac{1}{2})}](https://tex.z-dn.net/?f=SD%3D%5B%5Cfrac%7B%5Ctext%7Btotal%20probability%28return-expected%20return%29%7D%5E2%7D%7B%5Ctext%7Btotal%20probability%7D%7D%5D%5E%7B%28%5Cfrac%7B1%7D%7B2%7D%29%7D)
= ![[\frac{140.261139^2}{140.261139}]^{\frac{1}{2} }](https://tex.z-dn.net/?f=%5B%5Cfrac%7B140.261139%5E2%7D%7B140.261139%7D%5D%5E%7B%5Cfrac%7B1%7D%7B2%7D%20%7D)
= 11.84319 ≈ 11.84% approx.
