What is the probability of tossing a penny and landing on heads three times in a row

Mathematics

Dahasolnce [82]2 years ago

Answer:

\boxed {\frac{1}{8}}

Keys:

• \frac{a^x}{b^x} = \frac{?}{?}

For this problem, the exponents will be 3 since the coin is being tossed 3 times, meaning we multiply the number next to the exponent by itself the number of times the exponent says to. On the other hand, we have two sides of a coin; heads and tails, so we represent heads with the fraction of one-half.

Step-by-step explanation:

\frac{1^3}{2^3} = \frac{1}{8}

|\Omega|=2^3=8\\|A|=1\\\\P(A)=\dfrac{1}{8}=12.5\%

Target sells AAA batteries for $1.10 and AA batteries for $0.50. They sold 350 total batteries earning a total of $560. How many
satela [25.4K]

Answer:

This is not possible because the selling of  number of AA  batteries cannot be negative.

Step-by-step explanation:

Let us assume that the number of AAA batteries sells be x .

Let us assume that the number of AA batteries sells be y.

As given

Target sells AAA batteries for $1.10 and AA batteries for $0.50. They sold 350 total batteries earning a total of $560.

Equations becomes

x + y = 350

1.10x + 0.50y = 560

Simplify the above equation

\frac{110x}{100} + \frac{50y}{100} = 560

110x + 50y = 56000

Two equations becomes

x + y = 350

110x + 50y = 56000

Multiply x + y = 350 by 50 and subtracted from 110x + 50y = 56000 .

110x - 50x + 50y - 50y = 56000 - 17500

60x = 38500

x = \frac{38500}{60}

x = 641 .6 (Approx)

Put this value in the equation x + y = 350 .

641.6 + y = 350

y = 350 - 641.6

y = -291.6

This is not possible because the selling of  number of AA  batteries cannot be negative.

Which table represents an arithmetic sequence?
andriy [413]

An arithmetic sequence is a sequence of integers with its adjacent terms differing with one common difference. The table that represents an arithmetic sequence is the third table.

<h3>What is arithmetic sequence?</h3>

An arithmetic sequence is a sequence of integers with its adjacent terms differing with one common difference.

The explicit formula for any arithmetic series is given by the formula,

aₓ = a₁ + (x-1)d

where d is the difference and a₁ is the first term of the sequence.

For the table to be in an arithmetic sequence, the difference between any two consecutive terms must be equal.

  • For the first table, the difference between the first two terms is -6, while for the next two terms it is -12. Thus, it is not an arithmetic sequence.
  • In the second table, the difference between the first two terms is 2 while the difference between the next two terms is 4. Thus, it is not an arithmetic sequence.
  • In the third table, the difference between the first two terms is 1.4, the difference between the next two terms is 1.4. Also, it last two terms the difference is 1.4. Thus, it is an arithmetic sequence.

Hence, the table that represents an arithmetic sequence is the third table.

The measure of the vertex angle in an isosceles triangle is six less than four time the measure of the base angle. find the meas
blagie [28]
An isosceles triangle is a special type of triangle that has two equal sides. Consequently, the two base angles are also equal. Since the interior angles of a triangle should sum up to 180°, the general equation should be

180° = 2*Base angle + Vertex angle

Let the base angle be x. Thus, the vertex angle is equal to
Vertex angle = 4x - 6
Substituting,
180 = 2x + 4x - 6
x = 31°

Vertex angle = 4(31°) - 6 
Vertex angle = 118°
