So, on solving the provided question we can say that Percent = 140/250 x100 = 56%

A percentage in mathematics is a figure or ratio that is stated as a fraction of 100. The abbreviations "pct.," "pct," and "pc" are also occasionally used. It is frequently denoted using the percent symbol "%," though. The amount of percentages has no dimensions. With a denominator of 100, percentages are basically fractions. To show that a number is a percentage, place a percent symbol (%) next to it. For instance, if you correctly answer 75 out of 100 questions on a test (75/100), you receive a 75%. To compute percentages, divide the amount by the total and multiply the result by 100. The percentage is calculated using the formula (value/total) x 100%.

A percentage is a ratio of one unit of an event's result to the entire sample multiplied by 100%. It denotes parts per 100. We divide the percentage of the sample that liked the options by the total sample to arrive at the calculation. As a result, we compute:

Percent = 140/250 x100 = 56%

There are 48 different possible outcomes.

The total number of possible outcomes in a scenario like this is determined by finding the product of the number of possible outcomes for each individual event.

Independent events are events that are not affected by each other and have no influence on each other's outcome. The probability of two independent events occurring together is the product of their individual probabilities.

When flipping a coin, there are 2 possible outcomes (heads or tails).

When rolling a fair die with 4 sides, there are 4 possible outcomes (1, 2, 3, or 4).

When rolling a fair die with 6 sides, there are 6 possible outcomes (1, 2, 3, 4, 5, or 6).

To find the total number of possible outcomes, we multiply the number of outcomes for each event:

2 * 4 * 6 = 48

Therefore, there are 48 different possible outcomes.

The number of candy bars that Beth has sold, given the total they have sold and the amount sold by Carly, is 125 candy bars

To find the number of candy bars that Beth has sold, you can assume that the amount of candy sold by Carly is denoted as x.

This means that the amount of candy bars sold by Beth is:

= 2x - 1

The total sold by both Beth and Carly is therefore:

= 2x - 1 + x

The number of candy bars sold by Carly is:

188 = 2x - 1 + x

188 = 3x - 1

3x = 188 + 1

x = 189 / 3

x = 63

This means that the candy bars sold by Beth is:

= 2 ( 63 ) - 1

= 126 - 1

= 125 candy bars

We know that;

If 4x + 3 is a factor of 20x³ + 23x² - 10x + k, then, the value of x satisfy the given equation.

Hence, We get;

The value of x is,

⇒ 4x + 3 = 0

The radius of the circle is 48 feet.

Circle:

The round plane figure whose boundary (the circumference) consists of points equidistant from a fixed point (the center)

The arc length of a circle is given by the formula arc length = (angle/360) * 2 * pi * radius.

In this case, the angle is 75 degrees, and the arc length is 10* pi feet.

So, we can set up the equation: (75/360) * 2 * pi * r = 10 * pi

Solving this equation for the radius, we get: r = (10pi) / ( (75/360) * 2 * pi) = (10360) / 75 = 48 feet. So, the radius of the circle is 48 feet.

The domain and range for the function W = 15T + 400 is domain = set of all real numbers from 0 to 90 and range = set of all real numbers from 400 to 1750.

What is the range and domain of a function?

A function's range includes all conceivable values for y. Y = f(x) is the formula to determine a function's range. It is only a function in a relation if each x value has exactly one y value.

The collection of all potential inputs for a function is its domain.

The function for Total amount of water in the tank is given as -

W = 15T + 400

Where, T is the total number of minutes when the water is added.

So, according to the definition of range and domain -

T = domain = Number of minutes when the water is added

W = range = Total amount of water in the tank

W was a function of T for the next 90 minutes.

So, the domain will be the set of all real numbers from 0 to 90.

At, T = 0 -

W = 15(0) + 400

W = 400

At, T = 90 -

W = 15(90) + 400

W = 1350 + 400

W = 1750

So, the range will be set of all real numbers from 400 to 1750.

The equation of a curve in the xy-plane is given by F(x,y) = 0. To find such a curve that passes through the point (0,3) and whose tangent line at a point (x,y) has a slope of 2x/y^2, we can use the method of implicit differentiation.

First, we can find the equation of the tangent line at a point (x,y) on the curve by computing the derivative of F(x,y) with respect to x and setting it equal to 2x/y^2. This gives us:

F_x(x,y) = 2x/y^2

Next, we can use the fact that the curve passes through the point (0,3) to set up the following equation:

F(0,3) = 0

Solving for F(x,y) in terms of x and y and substituting in the equation for F_x(x,y) gives the implicit equation of the curve is

y^2 = 2x*F(x,y) or y^2 = 2x*F(x,y) + C where C is constant

This is the equation of a curve in the XY-plane that passes through the point (0,3) and whose tangent line at a point (x,y) has a slope of 2x/y^2.

Therefore, The equation of the curve in the XY-plane that passes through (0,3) and whose tangent line at a point (x,y) has slope 2x/y^2 is y^2 = 2x*F(x,y) or y^2 = 2x*F(x,y) + C where C is constant.

To prove that the diagonals of an isosceles trapezoid are congruent, we will first define the terms and draw a diagram of the isosceles trapezoid.An isosceles trapezoid is a quadrilateral with two congruent legs, a pair of parallel bases, and congruent base angles.Let's call the isosceles trapezoid ABCD and let the parallel sides be AB and CD, and the congruent legs be AD and BC. Let the diagonals be AC and BD.Since, AD and BC are congruent legs, therefore ∠BAD = ∠CAD by the definition of congruent legs.And since ABCD is a trapezoid, therefore, AB || CD and therefore, ∠BAD = ∠CBD, due to alternate angles are congruent.Therefore, ∠CAD = ∠CBD, by CPCTC (corresponding parts of congruent triangles are congruent)AC = BD , since both are congruent by ASA (angle-side-angle) congruence.Thus, the diagonals of an isosceles trapezoid are congruent.

1. Calculate the expected value (μ) for the Poisson Distribution:

μ = λ × t = (1 leak per 1,000 meters) × (2,500 meters) = 2.5

2. Calculate the probability of no leaks using the Poisson Distribution:

P(X=0) = e-μ × (μ^0/0!) = e-2.5 × (2.5^0/0!) = 0.857

A probability is a numerical representation of the likelihood or chance that a specific event will take place. Both proportions ranging from 0 to 1 and percentages ranging from 0% to 100% can be used to describe probabilities.

A long hit with success has a 0.4 chance of happening. The following formula can be used to determine which strategy—the short hit or the long hit—will improve the expected value of the score:

Expected value of long hit = P(successful hit)4.2 + P(unsuccessful hit)5.4

"A rational number is a number that can be expressed as the quotient or fraction p/q of two integers, a numerator 'p' and a non-zero denominator 'q'."

Therefore, when we are multiplying two rational numbers, their product must be a rational number.

Step-by-step explanation:

To make a boxplot, we need to know the minimum, Q1, median, Q3, and maximum.

The minimum is the smallest value: 15

The maximum is the largest value: 34

The median is found by arranging the numbers from smallest to largest and finding the middle point:

15, 20, 25, 25, 27, 28, 30, 34; there is not an exact middle here so we take the two middlemost points and divide by 2: 25+27/2 = 52/2 = 26

Q1 takes the numbers to the left of the median and finds the middle of those points. 15, 20, 25, 25. Again, there is no exact middle, so we use the same method as above. 20+25/2 = 22.5

Q1 takes the numbers to the right of the median and finds the middle of those points. 27, 28, 30, 34. Again, there is no exact middle, so we use the same method as above. 28+30/2 =  29

Step-by-step explanation:

the sumof angles of triangle is 180

so 6x+10+x+17+4x-34=180

11x-7=180

11x=187

x=17

Answer:

x = 17

Step-by-step explanation:

Since we know the angles of a triangle add up to 180, we can make the equation:

6x + 10 + x + 17 + 4x - 34 = 180

Then, we add 34 to both sides and put like terms near each other:

6x + x + 4x + 10 + 17 = 214

Then, combining like terms and subtracting 27 from both sides gives us:

11x = 187

Divide both sides by 11 gives us:

x = 17

So, the value of x = 17.
