The probability that the first winner randomly selects the card for the pizza topped with ham, artichoke hearts, and pepperoni is 1/560 given that there are 16 toppings to choose from. This can be obtained by finding the total number of all possible three-topping pizzas (3 distinct toppings) using combination formula and finding the probability.
What is the required probability?Given that there are 16 toppings,
the total number of all possible three-topping pizzas,
ⁿCₓ = [tex]\frac{n!}{x!(n-x)!}[/tex] = 16!/[3!(16-3)!] = 16!/[3!(13)!] = 14×15×16/3×2 =560
Probability of choosing pizza topped with ham, artichoke hearts, and pepperoni,
P(ham, artichoke hearts, pepperoni) = 1/560
Hence the probability that the first winner randomly selects the card for the pizza topped with ham, artichoke hearts, and pepperoni is 1/560 given that there are 16 toppings to choose from.

the toll on a highway us based on the miles driven. If the toll in a 15-mile stretch on a highway is $0.60. find the cost to drive a 80-mile stretch
Answer: $3.20
Step-by-step explanation:
We have
15-mile stretch = $0.60
80-mile stretch = x
Cross Multiply
15 × x = 80 × $0.60
x = 80 × $0.60/15
x = $3.20
Hence, the cost to drive an 80-mile stretch is $3.20

Find the length of side xx in simplest radical form with a rational denominator.
Answer:
x = √22

Does 8cm 15cm and 17cm form a right triangle?
Answer:
No, the sides of a right triangle must obey the Pythagorean theorem, which states that the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides. In this case, 8^2 + 15^2 = 64 + 225 = 289, which is not equal to 17^2 = 289. Therefore, 8cm, 15cm, and 17cm do not form a right triangle.

The perimeter of a rectangle is 108 ft. If the length is 24 ft more than the width, find the dimensions of the rectangle. 
The dimensions of the rectangle will be -
x {length} = 39 ft
y {width} = 15 ft
What is the area of a rectangle?The area of a rectangle is -
Area = Length x Breadth
A = L x B
Given is the perimeter of a rectangle is 108 ft. Also the length is 24 ft more than the width.
We can write the length is equivalent to -
x {length} = y {width} + 24
The perimeter will be -
2(x + y) = 108
x + y = 54
y + 24 + y = 54
2y = 30
y {width} = 15 ft
Then, we can write the length as -
x {length} = 15 + 24 = 39
x {length} = 39 ft
Therefore, the dimensions of the rectangle will be -
x {length} = 39 ft
y {width} = 15 ft

What is the formula to find centre?
The general equation to find centre of a circle is ( x - h )^2 + ( y - k )^2 = r^2, where ( h, k ) is the center and r is the radius.
Centre of the CircleThe location of a moving point on a plane such that its separation from a stationary point on the plane remains constant or fixed is described as a circle. The centre of the circle is the name given to the fixed point
A circle's centre and radius make up its 2D shape. Knowing the circle's centre and radius allows us to draw any circle. The number of radii that a circle can have is unlimited. The intersection of all the radii constitutes the centre of a circle. It is also known as the centre of the circle's diameter.
Center of Circle FormulaThe general equation of a circle is another name for the centre of circle formula. If the radius is r, the center's coordinates are (h,k), and any point on the circle is (x,y), the centre of the circle formula is as follows:
(x - h)2 + (y - k)2 = r2
2 = r2
Also known as center of the circle equation. we'll use this formula to determine a circle's equation or centre.

2 students did not attend the Sports Day.
In mathematics, a fraction is used to denote a portion or component of the total. It stands for the proportionate pieces of the whole. The numerator and denominator are the two components that make up a fraction.
Given that,
Total number of students in a class = 24
Total number of students chosen for drills = 7/14 = 7/14 *24 = 12
Total number of students chosen for various races = 4/16 = 4/16 *24 = 6
Total number of students chosen for gymnastics= 1/6= 1/6* 24 = 4
Thus, the Total number of students participating in sports day = 12+6+4 = 22
Hence, the Total number of students that did not attend sports day= 24 - 22 = 2
Therefore, 2 students did not attend the Sports Day
Correct question: Out of a class of 24 students, 7/14 of the total students were chosen for drills, 4/16 of the total students were chosen for various races, and 1/6 of the total took part in gymnastics. The rest of them did not attend the Sports Day.

A transformation modifies the parent function's graph.
What is meant by Transformations?The graph of a parent function is changed by a transformation. Transformations come in three different flavors: translations, reflections, and dilations.
A point, line, or geometric object can be changed in four different ways that are all collectively referred to as transformations. The pre-image is the shape of the object as it was originally, and the transformed shape of the object is termed the image.
Making pictures or replicas of an object is part of transformation geometry. You are introduced to transformation geometry in grade 9 through the use of translation, reflection, dilation, and rotation.
The foundation of the problem transformation approach is the notion that, if we are unable to address the given problem directly, we will move it to a setting where we can do so. The method's fundamental component is how the problem is broken down into smaller tasks.

By Using Pythagorean Theorem, the value of x is 6.2 units.
Pythagorean Theorem:
In mathematics, the Pythagorean Theorem or Pythagorean Theorem is the fundamental relationship in Euclidean geometry between the three sides of a right triangle. It states that the area of a square whose side is the hypotenuse (opposite the right angle) is equal to the sum of the areas of the squares on the other two sides. This theorem can be written as an equation for the lengths of sides a, b and hypotenuse c and is often called the Pythagorean equation.
a² +b² =c²
Now,
By using the Pythagorean theorem:
Hypotenuse² = Perpendicular² + Base²
Now,
In the Δ ABD
As given
DB² = DA² + AB²
As given
DB = 13 units
AB = 9 units
Putting values in the above
13² = 9²+ DA²
169 - 81 = DA²
88 = DA²
Now,
In ΔABC
AB² = AC² + CB²
(As given AB = 9 units , CB = x)
9² = AC² + x²
AC ² = 81 - x²
Now in ΔADC.
AD² = AC² + DC ²
As
AC ² = 81 - x²
DC = 13 - x
AD = [tex]\sqrt{88}[/tex]
(√88)² = 81 -x² +( 13 - x²)
By using the formula (a + b)² = a² + b² + 2ab
88 = 81 - x² + 13²- 2 × 13 × x + ²
⇒ 88 = 81 - x² + 13² - 26x + x²
⇒ 88-81 - 169 = -26x
⇒ 88-250 =-26x
⇒ -162 = - 26x
x = 6.2 (Approx.)
Therefore the value of x is 6.2 units.

you select a sample of 30 scores from a population of 1,000 scores. you compute the mode, median, and mean on the sample of 30 scores. you then select another sample of 30 scores from the same population. what measure of central tendency is likely to vary least between your first and second samples
The measure of central tendency that is likely to vary least between the first and second samples of 30 scores is the median.
The median is less affected by outliers and variations in the sample compared to the mean and mode, making it less likely to vary between samples.
The median is a measure of central tendency that represents the middle value of a dataset when it is ordered by value. It is a robust statistic, which means that it is not easily affected by outliers or variations in the sample. This is because the median only looks at the middle value of a dataset, and does not take into account the values of the entire dataset, unlike the mean.
The mode, on the other hand, is the value that appears most frequently in a dataset. It is affected by variations in the sample because it is based on the frequency of values. A different sample of the same population may have a different distribution of values, resulting in a different mode.
The mean is the sum of all the values in a dataset divided by the number of values. It is affected by outliers, as a single large or small value can greatly affect the mean. In small samples, the mean can be affected by small variations in the sample.
In conclusion, since the median is based only on middle value of the sample, it is less affected by variations in the sample and outliers, making it less likely to vary between samples.
