The probabilities are 1. 27/50, 2. 3/4, 3. 31/100, 4. 25/46, 5. 25/48

What is probability ?

The area of mathematics known as probability deals with numerical descriptions of how likely it is for an event to happen or for a claim to be true. A number between 0 and 1 is the probability of an event, where, broadly speaking, 0 denotes the event's impossibility and 1 denotes its certainty.

A probability is a number that expresses the possibility or likelihood that a specific event will take place. Probabilities can be stated as proportions with a range of 0 to 1, or as percentages with a range of 0% to 100%.

A probability is the number of desired outcomes divided by the number of total outcomes.

Item 1:

54 out of 100 people prefer bacon, hence:

P = 54/100

  = 27/50

Item 2:

Out of 100 people, 54 prefer bacon, 21 prefer sausage but pancakes, hence 54 + 21 = 75 desired outcomes, hence:

P = 75/100

  = 3/4

Item 3:

31 out of 100 people prefer bacon and pancakes, hence:

P = 31/100

Item 4:

Out of 46 people that prefer sausage, 25 prefer french toast, hence:

P = 46 / 25

Item 5:

Out of 48 people that prefer french toast, 25 prefer sausage, hence:

P = 48 / 25

It will cost $225 to pour 25 yd3 of concrete with 3 workers working at a rate of $15 per hour.

To determine the cost to pour 25 yd3 of concrete, you can use the following formula:

cost = (number of workers * worker rate per hour * number of hours)

In this case, the number of workers is 3, the worker rate per hour is $15, and the number of hours can be calculated by dividing the volume of concrete to be poured (25 yd3) by the rate at which the workers can pour concrete (5 yd3 per hour). Therefore, the number of hours it will take to pour 25 yd3 of concrete is 25/5=5 hours.

Plugging these values into the formula gives:

cost = (3 workers * $15/hour * 5 hours) = $<<3155=225>>225

H² = b¹ × b²

So using this formula (which can be proven by triangle similarity) can help us to find x

10² = 4x × x ===>> x =5

Answer: Therefore, the range of values of x for which (3x-7)(x-5) ≥x+5 is x<5 or x>5, or x∈(-∞,5)∪(5,∞).

Step-by-step explanation: To find the range of values of x for which (3x-7)(x-5) ≥x+5, we first need to find the values of x for which the inequality is satisfied. We can do this by setting each factor equal to 0 and solving for x.

Setting (3x-7) equal to 0 gives us x=7/3. Setting (x-5) equal to 0 gives us x=5.

Next, we need to consider the signs of the factors. If both factors are positive or both are negative, the inequality will be satisfied. If one factor is positive and the other is negative, the inequality will not be satisfied.

For x<5, both factors are negative, so the inequality is satisfied. For x>5, both factors are positive, so the inequality is satisfied.

Therefore, the range of values of x for which (3x-7)(x-5) ≥x+5 is x<5 or x>5, or x∈(-∞,5)∪(5,∞).

Answer:

Let x be the shorter side of the rectangular house. Since the length of the house is two-and-a-half times its width, we can write this as 2.5x. The area of a rectangle is given by the formula length * width, so the area of the rectangular house in terms of x is 2.5x * x = 2.5x^2. This is the expression for the area of the rectangular house in terms of the shorter side x.

Answer:

[tex]2.5x^2[/tex]

Step-by-step explanation:

Let x be the shorter side of the rectangle, which is also its width (w), so:

[tex]w=x[/tex]

Given that the length of the rectangle is two-and-a-half times its width, this means the length (l) can be expressed as:

[tex]l=2.5x[/tex]

The area of a rectangle (A) is the product of its length (l) and width (w):

[tex]A =l \cdot w[/tex]

Substitute the expressions for length and width into the formula for area:

[tex]A=2.5x \cdot x[/tex]

Simplify this expression:

[tex]A=2.5x^2[/tex]

Therefore, the expression for the area of the rectangle in terms of x is:

[tex]\Large\boxed{\boxed{2.5x^2}}[/tex]

Answer: 26, 28, 30

Explanation:

Let's define a variable x to represent the least of the three consecutive even integers. This means that the three integers are x, x + 2, and x + 4.

We can write the given information as an equation:

3 * (x + 4) = 2 * x + 38

We can solve for x by moving all the terms with x to one side of the equation and all the other terms to the other side:

3 * (x + 4) - 2 * x = 38

Then we can distribute the 3 and the -2 to get:

3 * x + 12 - 2 * x = 38

And then we can combine like terms on each side of the equation:

x + 12 = 38

Finally, we can subtract 12 from both sides to solve for x:

x = 26

Therefore, the three consecutive even integers are 26, 28, and 30.

We can check our solution by substituting these values back into the original equation and verifying that it holds true:

3 * (26 + 4) = 2 * 26 + 38

3 * 30 = 52 + 38

90 = 90

The equation holds true, so our solution is correct.

The particular solution that satisfies the given initial condition is y = 1. This is the solution to the given initial-value problem.

To solve this initial-value problem, we must first note that the given differential equation is homogeneous. This means that if y is a solution to the given equation, then so is cy, where c is an arbitrary constant. Thus, the first step in solving this initial-value problem is to find the general solution of the homogeneous equation. To do this, we can use the method of separation of variables.

This method involves separating the variables x and y on opposite sides of the equation, and then integrating both sides with respect to their respective variables. Doing this yields:

∫xy2 dy = ∫(y3 − x3) dx

Integrating both sides of the equation with respect to y yields:

y3x2/3 + C1 = x4/4 + C2

where C1 and C2 are arbitrary constants. Rearranging this equation yields:

y3 = 4x4/3 − 4C2x2/3 + 4C1

Now, we can use the given initial condition, y(1) = 1, to determine the value of the arbitrary constants. Substituting x = 1 and y = 1 into the equation yields:

13 = 4/3 − 4C2/3 + 4C1

Solving for C1 and C2 yields:

C2 = 0, C1 = 3/4

With the arbitrary constants determined, we can now find the general solution of the homogeneous differential equation. Substituting the values of C1 and C2 into the equation yields:

y3 = 4x4/3 − 3/4

This equation is the general solution of the given homogeneous differential equation. To solve the initial-value problem, we must now find the particular solution that satisfies the given initial condition. To do this, we can substitute the initial condition, y(1) = 1, into the general solution to obtain:

13 = 4/3 − 3/4

Solving for y yields:

y = 1

Pentagon:

                  A pentagon is a geometrical shape, which has five sides and five angles. Here, “Penta” denotes five and “gon” denotes angle.

If a pentagon is regular, then all the sides are equal in length, and five angles are of equal measures. If the pentagon does not have equal side length and angle measure, then it is known as an irregular pentagon.

The sum of all the interior angles for a regular pentagon is 540°.

hence,

           Value of each interior angle = 540°/5

                                                       = 108°

You must babysit for 8 weeks to earn enough money to buy the new gaming chair.

Step-by-step explanation:

To determine how many weeks you must babysit to earn enough money to buy the new gaming chair, we need to write and solve an equation that represents the relationship between the money you have saved, the money you earn each week, and the cost of the gaming chair.

First, we can let w represent the number of weeks you must babysit. Then, we can set up the equation:

Earnings + Savings = Total Cost

Substituting the known values into the equation, we have:

Earnings + Savings = Total Cost

$37.50w + $155.95 = $455.95

To solve the equation, we can first subtract $155.95 from both sides of the equation:

$37.50w + $155.95 - $155.95 = $455.95 - $155.95

$37.50w = $300.00

Next, we can divide both sides of the equation by $37.50 to find the value of w:

$37.50w / $37.50 = $300.00 / $37.50

w = 8

Therefore, you must babysit for 8 weeks to earn enough money to buy the new gaming chair.

Answer:

1.5A

Step-by-step explanation:

To find the current that the motor will require, we can use the formula for power, which is given by:

P = E * I

where P is the power, E is the voltage, and I is the current. Substituting the values for the power and voltage into the formula, we get:

180 = 120 * I

Dividing both sides of the equation by 120, we get:

1.5 = I

Therefore, the current that the motor will require is 1.5 amps.

Step-by-step explanation:

The formula for power is P = E x I, so the current required by the motor is equal to the power divided by the voltage. In this case, the current required by the motor is 180 watts / 120 volts = 1.5 amps.
