The marks obtained by Sean and Zack in a test are 4x+6 and 3x+15 respectively. If Sean obtains at least 2 marks more than Zack, what is the minimum value of x?

The minimum value of x will be 11.  

Step-by-step explanation:

We are given that the marks obtained by Sean and Zack on a test are (4x + 6) and (3x + 15), respectively. Sean obtained at least two more marks than Zack, and we want to find the minimum value of x.

Since Sean obtained at least two more marks than Zack, we can write that:

Solve for x:

Hence, the value of x must be greater than or equal to 11.

Then the minimum value of x will be 11.

0.16 or 16%

step-by-step explanation:

lets take a coin for example.

if you toss it twice, it has a 1/4 chance of landing on heads both times because 1/2 * 1/2 is 1/4.

with the cards, the chance of picking dog is 0.4. having two people pick one is like picking a card twice in a row. so 0.4 * 0.4 is 0.16, or 16%
