Formula for the Conditional Probability is:
P ( A \ B ) = P ( A ∩ B ) / P ( B )
But it is not possible to have the probability greater than 1.
0 ≤ P ( n ) ≤ 1 
So let`s assume that: P ( A ∩ B ) = 1320 and P ( B ) = 1325
P ( A \ B ) = 1320 / 1325 = 0.9962

F(x) = 5x ^ 2 and g(x) = x + 1 find (fg)(x)
Vilka [71]

According to the question given,f(x)=5x^2,g(x)=x+1 (fg)(x)  is f(x).g(x)=5x^3+5x^2

Which is not given in the options.

Step-by-step explanation:

We are given:

f(x)=5x^2

g(x)=x+1

We need to find (fg)(x)

Solving:

(fg)(x)=f(x).g(x)\\f(x).g(x)= 5x^2*(x+1)\\f(x).g(x)=5x^3+5x^2

According to the question given, (fg)(x)  is f(x).g(x)=5x^3+5x^2

Which is not given in the options.

What is the distance between (-2 1/2, -3) and (1, -3)
Igoryamba

Answer:

D

Step-by-step explanation:

(-2 1/2, -3) = (-5/2 , -3)    &  (1, -3)

Distance=\sqrt{(x_{2}-x_{1})^{2}+(y_{2}-y_{1})^{2}}\\\\ =\sqrt{(1-[\frac{-5}{2}])^{2}+(-3-[-3])^{2}}\\\\ =\sqrt{(1+\frac{5}{2})^{2}+(-3+3)^{2}}\\\\ =\sqrt{(\frac{7}{2})^{2}} \\\\=\frac{7}{2}\\\\=3\frac{1}{2}
