What is the answer to: 3x-11(that part is under a square sign) then =7. Please give an explanation to this problem thank you!

Step-by-step explanation:

We want to solve the radical equation:

We squat both sides to get;

We evaluate the exponent to get:

Add 11 to both sides:

Divide both sides by 3 to get:

This implies that:

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%
