The value of the symbol to represent the ray XY is →
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as A
Now , the value of A is
Substituting the values in the equation , we get
A ray of light is the direction that light energy moves through a medium. It is represented by a line that is straight and has an arrow on it
So , the symbol to represent the ray of light XY will be denoted by →
Hence , the equation is solved

Answer:
D
Step-by-step explanation:
choice A is not guaranteed since the values varied from 0 to 7.
choice B seems alright, but doesn't include about or anything about the long run.
choice C is incorrect because 50% are less than 3.12 and 50% are greater than 3.12.
choice D seems pretty good, since it says average, long run, approach, etc.
choice E is incorrect because it says "will be". It is not definite.
Final answer:
The mean of 3.12 represents the average number of days per week that members are expected to visit the fitness center.
Explanation:
The mean of the random variable X, which represents the number of days per week that members visit a fitness center, is 3.12. This means that on average, members go to the fitness center about 3.12 days each week when considering all the members surveyed. It's an overall trend that indicates the central tendency or the 'typical' value that we would expect in this data set. It is calculated by multiplying each number of visit days by its relative frequency and adding all these products together, then dividing by the total number of members.
Step-by-step explanation:
x + y = 16 (*)
x^2 + y^2 = 146 (**)
(*) <=> x= 16-y
substitute x = 16 - y
(**) <=> (16-y)^2 + y^2 = 146
<=> y^2 - 2.16.y + 16^2 + y^2 = 146
<=> 2y^2 - 32y + 110 = 0
<=> y^2 - 16y + 55 = 0
<=> (y-11)(y-5) = 0
<=> y=11 or y= 5
For y = 11, we have x= 16-11=5
For y=5, we have x= 16-5=11
Answer: (x,y) = (11,5) ; (5,11)
The ribbon was 3 feet
long. How many pieces
would he cut if they were
all 0.75 feet long?
Answer: The required number is -3.
Step-by-step explanation: Given that three added to 8 times a number is the same as 3 times the value of 2 times the number minus 1.
We are to find the number.
Let x represents the given number.
Then, according to the given information, we have
Thus, the required number is -3.
B. A three-dimensional solid made from a pile of similar two-dimensional circles that grow smaller as the solid gets taller until it reaches a point at the vertex
C. A three-dimensional solid consisting of a base, a point not in the same plane as the base, and all the points between them
D. A three-dimensional solid consisting of two parallel congruent polygons and all the points between them
A cone is best described in the point:
B. A three-dimensional solid made from a pile of similar two-dimensional circles that grow smaller as the solid gets taller until it reaches a point at the vertex.
Three-dimensionalfigures are solid shapes, having three dimensions: length, width, and height.
Some examples of three-dimensionalfigures are cube, cuboid, cone, and cylinder.
We will discuss the description of all the figures given to us, try to know which figure is the description about, and then will tell what is the description of a cone.
A. A three-dimensional solid made from two parallel and congruent discs not in the same plane and all the points between them.
- The description is of a cylinder. A cylinder has both its end as two parallel and congruent discs, which are not on the same plane and include all the points between the discs.
B. A three-dimensional solid made from a pile of similar two-dimensional circles that grow smaller as the solid gets taller until it reaches a point at the vertex.
- The description is of a cone. A cone has a circular base, which grows smaller and smaller to a point.
C. A three-dimensional solid consisting of a base, a point not in the same plane as the base, and all the points between them.
- The description is of a pyramid. A pyramid can have any base, that grows smaller and smaller to a point.
D. A three-dimensional solid consisting of two parallel congruent polygons and all the points between them.
- The description is of a prism. On either end of a prism are two polygonal forms that can be any shape with three or more sides.
∴ A cone is best described in the point:
B. A three-dimensional solid made from a pile of similar two-dimensional circles that grow smaller as the solid gets taller until it reaches a point at the vertex.
