a turn consists of rolling a standard die and tossing a fair coin. the game is won when the die shows a $1$ or a $6$ and the coin shows heads. what is the probability the game will be won before the fourth turn? express your answer as a common fraction.

Answers

The probability that the game will be won before the fourth turn is [tex]\frac{91}{216}[/tex].

What is probability?

Probability refers to the possibility of the occurrence of an event.

P(E) = probability of occurrence of an event E = [tex]\frac{Number Of Favourable Outcomes}{Total Number Of Outcomes}[/tex]

Now,

Probability of winning the game in first turn = [tex]\frac{1}{3}\frac{1}{2}=\frac{1}{6}[/tex]

Probability of losing the first game but winning the second one = [tex]\frac{5}{6}\frac{1}{6} = \frac{5}{36}[/tex]

Probability of losing the first two games but winning the third one = [tex]\frac{5}{6}(\frac{5}{6})\frac{1}{6} = \frac{25}{216}[/tex]

Thus, the probability of winning the game before fourth turn = [tex]\frac{1}{6}+\frac{5}{36}+\frac{25}{216}=\frac{91}{216}[/tex]

Hence, The probability that the game will be won before the fourth turn is [tex]\frac{91}{216}[/tex].

The length and the weight of 7 pipes are 24.5m and 43.3kg respectively, find the length and weight of 12 pipes

Answers

The length and the weight of the 12 pipe is found as 42 meters and 74.23 kg

What is referred as the unitary method?"It is a method in which we obtain the value of a single unit by subtracting the results of multiple units and thus the value of multiple units by subtracting the value of a single unit."We must first divide to discover the value of one thing, and then multiply to determine the significance of more or fewer things.

As, per the given question;

For, the seven pipes, the length is 24.5m.

7 pipes ---------> 24.5 m.

For the one pipe, use unitary method for solving;

Divide the equation by 7.

1 pipe -------->24.5/7 m.

For 12 pipes, multiply with 12 on both sides.

12 pipes --------> 24.5×12/7 m.

12 pipes --------->  42 m.

Thus, the length of the 12 pipes is 42 meters.

Now, calculate the weight.

For, the seven pipes, the weight is 43.3 kg.

7 pipes ---------> 43.3 kg.

For the one pipe, use unitary method for solving;

Divide the equation by 7.

1 pipe -------->43.3 kg./7

For 12 pipes, multiply with 12 on both sides.

12 pipes --------> 43.3 kg×12/7

12 pipes --------->  74.23

Thus, the weight of the 12 pipes is 74.23 kg.

The graph of h is a translation 6 units down and 2 units left of the graph of f(x)=x^2−7x. For each value of x, g(x) is 115% of h(x). Write a rule for g

Answers

The rule for the function g(x) is:

g(x) = 1.15*(x^2 - 3x -16)

How to write a rule for the function g?

First we know that the function f(x) is f(x) = x^2 - 7x

And we know that h(x) is a translation of 6 units down and 2 units to the left of f(x), then:

h(x) = f(x + 2) - 6

Now we know that g(x) is 115% of h(x), then we can write:

g(x) = 1.15*h(x)

Replacing h(x) by the rule above we get:

g(x) = 1.15*(f(x + 2) - 6)

Replacing the actual function there:

g(x) = 1.15*( (x + 2)^2 - 7*(x + 2) - 6)

g(x) = 1.15*( x^2 + 4x + 4 - 7x - 14 - 6)

g(x) = 1.15*(x^2 - 3x -16)

This is the rule for function g(x).

Jeffrey caught 8 worms in his backyard. 4 worms had a length of 3 inches. The other 4 worms were all the same size. The total length of all the worms combined is 32 inches. Which equation below represents the lengths of all the worms?
A 4x + 3x = 324x + 3x = 32
B 4(x + 3) = 324(x + 3) = 32
C 4x + 3 = 324x + 3 = 32
D 3(x + 4) = 32

Answers

Option (B) 4 ( x + 3 ) = 32 is the equation that represents the lengths of all the worms.

We are given that:

Jeffrey has 8 worms

The 4 worms in it has the length of 3 inches.

The expression would become:

Length = 4 × 3

Also, we are given that the rest 4 worms are of equal length.

Let that equal length be x

The expression becomes:

Length = 4 × x = 4 x

Also, we are given that the total length of the worms = 32 inches.

The equation becomes:

32 = 3 × 4 + 4 × x

4 ( x + 3 ) = 32

Therefore, option (B) 4 ( x + 3 ) = 32 is the equation that represents the lengths of all the worms.

Answers

Total number of students in a class is 50.

A class has 40% of women.

Total Number of women in a class = 20                              equation 1

Let total number of students in a class = x

According to the question a class has 40% of women. Mathematically we can write it as,

Total Number of women in a class = 40 % of x

Total Number of women in a class = ( (40x) / 100 )               equation 2

On equating equation 1 and equation 2, we get

What is an circuit?

Electronic components such as resistors, transistors, capacitors, inductors, and diodes are connected by conductive wires or traces that allow electric current to flow between them. It is a specific kind of electrical circuit, and in order for a circuit to be called electronic rather than electrical, there usually needs to be at least one active component present. Signals may be amplified, calculations can be made, and data can be transported from one location to another thanks to the combination of components and wires.

Although discrete components can be assembled into circuits and connected by single wires, it is now far more typical to use photolithographic processes to make interconnections on laminated substrates and solder the individual components to these linkages.

We first subtract 8 from both sides. We now divide both sides by -1. However, something to keep in mind, is when you multiply/divide by a negative number, you just flip the sign. In this case, we need to divide both sides of the equation by -1, to get b and our answer. So now, we need to find an answer from our answer choices that is smaller than -19.

If m< EBC = 3y+10 and m< ABE = 2y-20, find m< EBF.

Answers

The value of angle m< EBF  is determined as 56⁰.

What is the sum of angles in a straight line?

The sum of angles in a straight line is 180 degrees. The value of angle EBF can be determine using the concept of sum of angles in a straight line as shown below.

m< EBC  + m< ABE = 180

3y + 10 + 2y - 20 = 180

5y - 10 = 180

5y = 180 + 10

5y = 190

y = 190/5

y = 38

The value of m< EBF is calculated as follows;

Assuming equal division, m< EBF = m< ABE

m< EBF = 2y - 20

m< EBF = 2(38) - 20

m< EBF = 56⁰

Thus, the value of angle m< EBF  is determined as 56⁰.

$59.50. If the original price was :
$70, what
percentage of its original price were soccer
cleats sold for?

Answers

The percentage of its original price is -17.65%

How to determine the percentage of its original price?

The given parameters are

Selling price = $59.50

Original price = $70

The percentage of the original price is calculated as

Percentage = (Selling price - Original price)/Original price * 100%

Substitute the known values in the above equation

So, we have

Percentage = (59.50 - 70)/59.50 * 100%

Evaluate the difference in the above equation

So, we have

Percentage = -10.5/59.50 * 100%

Evaluate the quotient in the above equation

So, we have

Percentage = -0.1765 * 100%

Evaluate the product in the above equation

So, we have

Percentage = -17.65%

Hence, the percentage of its original price is -17.65%
