The probability of getting 0 heads in 4 tosses (or equivalently, 4 tails) is
.
So the desired probability is
To find the answer,
multiply the amount of calories in one kit kat bar by 16
218 * 16 = ?
The final answer is 3,488 calories
The new shower head dispenses 3 gallons of water per minute, as shown in the equation y = 3x.
So, 3 x 8 = 24.
Then, to find out how much he saves each day, you would find how much he used before,
11 x 8 = 88
Next we want to see how much Nathan saved, so we subtract the total,
88 - 24 = 64
Nathan saved 64 gallons.
The correct answer is the first choice. You can determine which angles are congruent by looking at the corresponding angles (angles that are in the same position) on the similar trapezoids). The angles would be congruent even though the shapes are not the same size.
