Suppose that the handedness of the last fifteen U.S. presidents is as follows:40% were left-handed (L)47% were Democrats (D)If a

president is left-handed, there is a 13% chance that the president is a Democrat.Based on this information on the last fifteen U.S. presidents, is "being left-handed" independent of "being a Democrat"?(A) Yes, since 0.40 * 0.47 is not equal to 0.13.(B) No, since 0.40 is not equal to 0.13.(C) No, since 0.47 is not equal to 0.13.(D) Yes, since 0.47 is not equal to 0.13.

Answer: Option 'c' is correct.

Step-by-step explanation:

Since we have given that

Probability that they were left handed P(L)= 40%

Probability that they were Democrats P(D)= 47%

So, P(L∩D) = 135 = 0.13

Now, to check whether they are independent or not.

We will find P(L) × P(D) is given by

P(L)\times P(D)=0.47\times 0.40=0.188

Since P(L) . P(D) ≠ P(L∩D)

So, they are not independent.

Hence, Option 'c' is correct.

What is the value of x in the equation 1.5(x + 4) – 3 = 4.5(x – 2)? 3 4 5 9
Arisa [49]

1.5(x + 4) - 3 = 3.5(x - 2)

We need to use the distributive property to simplify this.

1.5x + 6 - 3 = 3.5x - 7

<em><u>Subtract 1.5x from both sides</u></em>

6 - 3 = 2x - 7

<em><u>Simplify left side</u></em>

3 = 2x - 7

<em><u>Add 7 to both sides</u></em>

10 = 2x

<em><u>Divide both sides by 2</u></em>

x = 5
