Leona [35]

Answer:

The right answer is "0.70".

Step-by-step explanation:

The given query seems to be incomplete. Please find below the attachment of the full query.

By using the Bayes' theorem, we get

⇒  P[(X

By putting the values, we get

                                     =\frac{[P(2)+P(3)]}{[1-P(0)-P(1)]}

                                     =\frac{(0.20+0.15)}{1-0.20-0.30}

                                     =\frac{0.35}{0.5}

                                     =0.70

What is the value of x in the equation 1.5(х + 4) – 3 = 4.5(х – 2)?<br>​
Pavlova-9 [17]

Answer:

4

1.5(x+4) - 3 = 4.5( x-2)-----------------------open brackets on both sides

1.5 x +6 -3= 4.5x- 9.................................collect like terms

3+9 = 4.5 x- 1.5x

12=3x..................................divide by 3 both sides to get x

12/3=x

x=4
