Answer:

57.1%

Step-by-step explanation:

We know that a coin has only two sides, heads or tails. Therefore if of the 84 times, 36 times he fell in heads, the other times he fell in tails.

84 - 36 = 48 times fell in tails.

Therefore to calculate the percentage that fell in tails, it would be the ratio between the number of times it fell in tails and the total number of experiments:

48/84 = 0.571, and that is 57.1%

Which means that 57.1% of the times the coin was thrown fell into tails.

Answer:

57%

Step-by-step explanation:

Total number of times the coin was flipped=84

Number of Times the Coin Landed on Heads=36

Therefore:

Total Number of Flips=Number of Heads + Number of Tails

84=36+Number of Tails

Number of Tails=84-36=48

We want to calculate what percentage of the coin flips landed on Tails

=\frac{Number of tails}{Total Number of  Trials} X100\\=\frac{48}{84}X100

=57.14

The percentage of the coin flip that landed on Tails =57% ( to the nearest percent)

What is the value of x in the figure? Enter your answer in the box.<br> 145°<br> (2x + 15)°<br> x=
Nikolay [14]

Answer:

Answer: x=65

Step-by-step explanation:

Since they're vertical angles both sides are equal to 145 degrees

So, 145-15= 130 to get rid of the constant

Then, 130/2=65

To check you work add up all of your solutions to get 145

2*65=130 & 130+15=145

Therefore, x=65

How do I simplify the n^-6*n^3 topic "Negative and Zero Exponents"
Alchen [17]
Since you’re multiplying n^-6 and n^3, you can add the exponents: -6+3 = -3

n^-6 * n^3 = n^-3

If you need to finish without having a negative exponent in your answer, then remember a negative exponent means that factor is on the wrong side of the fraction.

n^-3 = n^-3 / 1 = 1/n^3

when the factor moves to the other side of the fraction, the side of the exponent changes.

A line segment is defined by which of the following statements?
kaheart [24]

The only given option that correctly defines a line segment is;

<u><em>Option C; All points between and including two given points.</em></u>

      In geometry in mathematics, a line segment is defined as a part of a line that is bounded by two distinct end points.

Now, let us look at the options;

Option A; This is not correct because a line segment must have 2 distinct endpoints

Option B; This is not correct because a line segment is a part of a line and not a set of points.

Option C; This is correct because it tallies with our definition of line segment.

Option D; This is not correct because a line segment does not extend infinitely.

For the graph Y equals 1 find slope of a line that is perpendicular to it in the slope of a line parallel to it
marishachu [46]

Answer:

The answer is Undefined (∞).

Step-by-step explanation:

The line y = 1 has a slope of 0, and the line parallel to it, for instance, y = 3, has the same slope, m1 = 0. For the slope of the line perpendicular to that parallel line is m2 = -1/m1, which is -1/0 = ∞
