The value of expression is 33
For evaluating the expression, we will keep the given values of variables in the expression. Further solving will be done according to the mathematical operators.
Rewriting the equation -
Value = 11 (a + 2b) + 2 (a - 2b)
Now keeping the values of variables in expression -
Value = 11 (-3 + 2×4) + 2 (-3 - 2×4)
Firstly solving the brackets
Value = 11 ( -3 + 8) + 2 (-3 - 8)
Value = 11 (5) + 2 (-11)
Performing multiplication
Value = 55 - 22
Performing subtraction
Value = 33
Hence, the expression for the given values of the variables is 33.

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).

How is finding a missing term of a geometric sequence using the geometric mean similar to finding a missing term of an arithmetic sequence using the arithmetic mean? How is it different?
The two are similar, because: in both AP and GP, we can find the mean value using first and last values.
The two are different because: in both AP and GP, different methods are used to find the mean value.
What is an arithmetic and a geometric progression?A series of numbers called an arithmetic progression or arithmetic sequence (AP) has a constant difference between the terms.A geometric progression, sometimes referred to as a geometric sequence in mathematics, is a series of non-zero numbers where each term following the first is obtained by multiplying the preceding one by a constant, non-zero value known as the common ratio.Now,
AP and GP are similar because the middle value, or mean value in both AP and GP, can be determined by using the initial and last values. They differ because there are various methods for calculating that number, and each phrase is distinguished by either a common ratio or a common difference.To learn more about arithmetic and geometric progressions, refer to the link: https://brainly.com/question/13899779

How much volume (in cm3 ) is gained by a person who gains 11.0 lblb of pure fat?
The person who have gained 11 lb. of pure fat will gain 5,500 cm³ of volume.
It is given in the question that the person gains 11 lb. of pure fat.
We have to find the volume (in cm3 ) gained by the person.
We know that,
The density of fat is about 0.9 grams/ml
Converting this in pounds, we get :-
0.9 grams/ml * 1 lb. / 454 grams * 1 ml / 1 cm³= 0.002 lb./cm³
We know the formula of density:-
Density = mass / volume
Hence,
Volume = mass / density
Volume = 11 / 0.002
Volume = 5,500 cm³.

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.
Therefore, Chantel will take approximately 12.19 hours to complete the triathlon with the given speed of his.

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.

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 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.
Therefore, The central angle is the angle made at the center of the polygon by any two adjacent vertices of the polygon.
