Answer:

0.25 or 1/4

Step-by-step explanation:

P(coin is flipped as head) = 0.5 or 1/2 (one of 2 sides)

P(coin is flipped as head twice) = P(coin is flipped as head) x P(coin is flipped as head)

= 0.5 x 0.5

= 0.25 or 1/4

<h3>How to calculate percentage of a number. Use the percentage formula: P% * X = Y</h3>
  • Convert the problem to an equation using the percentage formula: P% * X = Y.
  • P is 17%, X is 7.20, so the equation is 17% * 7.20 = Y.
  • Convert 10% to a decimal by removing the percent sign and dividing by 100: 10/100 = 0.10.

Therefore, It costs $122.4 dollars before the increase.

Answer:

The third option, -1/2(30) = -15

Step-by-step explanation:

If it decreases by 1/2, we know it has to be -1/2, and the days we are given are 30. We need to multiply -1/2 by 30 in order to find the water level after 30 days, which would be -15 (inches?) I hope this helped.
