The statement is sometimes true.
The given statement is ' The geometric mean for two positive integers is another integer.'
Geometric mean of two integers is the square root of their product.
If a and b are two integers, then geometric mean = [tex]\sqrt{ab}[/tex]
Its value need not be an integer always. In some cases the statement fails.
For example, let a = 3 and b = 6
Then geometric mean = [tex]\sqrt{3 \times 6} = \sqrt{18}[/tex] = 4.24, which is not an integer.
Now if a and b are equal numbers, we will get an integer as the geometric mean. Because then their product will be a perfect square and taking square root, we get the same number as the geometric mean.
Also consider a = 9 and b = 4
Then their geometric mean = [tex]\sqrt{36}[/tex] = 6
So sometimes the statement is true but not always.

F 155.9 ft
G 141.6 ft
H 127.3 ft
J 118.2 ft
The length from 3rd base to 1st base is 127.3 ft
The correct answer is an option (H)
In this question,
A baseball diamond is a square with 90 -ft sides.
A baseball "diamond" is a square, each side of length 90 ft, with home plate and the three bases on the four corners.
Let s be the side length of the square.
The length from the 3rd base to 1st base is the diagonal of the square.
Using Pythagoras theorem, we formulate
diagonal = √(s² + s²)
diagonal = √(2s²)
diagonal = s√2
diagonal = (90)√2
diagonal = 127.28 ft
Therefore, the length from 3rd base to 1st base is 127.3 ft
The correct answer is an option (H)

Find the missing angle
Find the value of x
Angle ∠ABC and angle ∠CDE are supplementary angles. Then the value of the variable x will be 18°.
What is an angle?The angle is the distance between the intersecting lines or surfaces. The angle is also expressed in degrees. The angle is 360 degrees for one complete spin.
Supplementary angle - Two angles are said to be supplementary angles if their sum is 180 degrees.
From the figure, the angle ∠ABC and angle ∠CDE are supplementary angles. Then we have
∠ABC + ∠CDE = 180°
2x + 8x = 180°
10x = 180°
x = 180° / 10
x = 18°
Then the value of the variable x will be 18°.

Are parallel lines (parallelism) and collinear points (collinearity) preserved under all transformations? Explain.
Yes, all transformations such as translations, reflections, dilations, and rotations preserve parallel lines (parallelism) as well as collinear points (collinearity).
Parallel lines:
Parallel lines are coplanar straight lines that don't intersect at any point in geometry. Parallel planes are planes that never meet in the same three-dimensional space. Parallel curves are those that do not touch or intersect and maintain a constant minimum distance.Collinear points:
The collinearity of a series of points in geometry is the property of their being on a single line.A set of points with this property is known as a collinear set. In a broader sense, the term has been applied to aligned objects, that is, things that are "in a line" or "in a row."So,
Translation, reflection, dilation, and rotation are all examples of transformation. In all of the preceding cases, parallel lines or collinear points will remain parallel or collinear.Therefore, yes, all transformations such as translations, reflections, dilations, and rotations preserve parallel lines (parallelism) as well as collinear points (collinearity).

A triangle with an angle that measures greater than 90° is a right triangle.
The given statement that A triangle with an angle that measures greater than 90° is a right triangle is a FALSE statement.
What is a triangle?A triangle is a 3-sided shape that is occasionally referred to as a triangle. There are three sides and three angles in every triangle, some of which may be the same.
There are many types of triangles such that right-angle triangles, equilateral triangles, and much more.
A right-angle triangle is a triangle whose any one interior angle is 90°.
Let's say the remaining angles are x and y degrees.
The sum of all interior angles is 180 degrees.
So,
x + y + 90 = 180
x + y = 90
x = 90 - y ⇒ x ≤ 90°
y = 90 - x ⇒ y ≤ 90°
Hence "The given statement that A triangle with an angle that measures greater than 90° is a right triangle is a FALSE statement".

Explain why the sum of the probabilities of two mutually exclusive events is not always 1 .
The probabilities of mutually exclusive events are always smaller than 1.
In statistics, what does a probability mean?
The probability serves as a gauge for how likely an event is to occur. It gauges how likely an event is. P(E) = Number of Favorable Outcomes/Number of Total Outcomes is the formula for probability.The probability of events that are mutually exclusive cannot ever be added up to greater than one.
Unless the same set of occurrences is also exhaustive, in which case the total of their probabilities is exactly 1, the probabilities of mutually exclusive events are always smaller than 1.
The likelihood that none of these occurrences, which are mutually exclusive, will occur is (1 - the sum of their probabilities).

A circular pillar candle is 2.8 inches wide and 6 inches tall. What are the lateral area and surface area of the candle? Round to the nearest tenth if necessary.
Lateral area and surface area of candle is 52.8 inches² and 65.1 inches².
We are given the height and width of pillar candle. So, firstly writing the formula of lateral area and surface area of cylinder followed by calculation.
Lateral area of cylinder = 2πrh, where r stands for radius and h represents height.
Surface area of cylinder = 2πrh + 2πr²
Radius = diameter÷2
Radius = 2.8÷2
Radius = 1.4 inches
Keep the values in formula for calculation -
Lateral area of cylinder = 2×3.14×1.4×6
Lateral area of cylinder = 52.78 inches²
Surface area of cylinder = 2×3.14×1.4×6 + 2×3.14×1.4²
Surface area of cylinder = 65.09 inches²
Rounding off to nearest tenth-
Lateral area of cylinder = 52.8 inches²
Surface area of cylinder = 65.1 inches²
Hence, the lateral area and surface area of cylinder is 52.8 inches² and 65.1 inches².

A central angle of a polygon is formed by line segments drawn from the center to two __ vertices.
The central angle is the angle made at the center of the polygon by any two adjacent vertices of the polygon.
The central angle is the angle made at the center of the polygon by any two adjacent vertices of the polygon. If you were to draw a line from any two adjacent vertices to the center, they would make the central angle. Because the polygon is regular, all central angles are equal. It does not matter which side you choose.
All central angles would add up to 360° (a full circle), so the measure of the central angle is 360 divided by the number of sides. Or, as a formula:
[tex]central \ angle = \frac{360}{n}[/tex] degrees
where n is the number of sides
The measure of the central angle thus depends only on the number of sides. The angle depends only on the number of sides, not the size of the polygon. If you change the number of sides, you will see that as the number of sides gets larger, the cenral angle gets smaller.

Chantel has a goal to complete a triathlon. The race consists of a 2.4-mile swim, a 112-mile bike ride, and a 26.2-mile run. In training, Chantel can swim at an average pace of 1.2mph. She rides her bike at an average of 18.8mph and runs at 6.2mph. Estimate how long it will take her to complete the triathlon.
Chantel will take approximately 12.19 hours to complete the triathlon with the given speed of his.
Total distance covered for the race is:
For swimming = 2.4 miles
Speed of Chantel in swimming = 1.2 miles per hour.
So, time taken for completing the swimming part = 2.4 / 1.2 = 2 hours.
For bike ride = 112 miles
Speed of Chantel in bike riding = 18.8 miles per hour
So, time taken for completing the bike riding part = 112 / 18.8 = 5.96 hours.
For running = 26.2 miles
Speed of Chantel in running = 6.2 miles per hour.
So, time taken for completing the running part = 26.2 / 6.2 = 4.23 hours.
Total time = 2 + 5.96 + 4.23 = 12.19 hours.
