The statement about the relationship of the data in the table is indicated in the option;

A proportional relationship is one in which one variable (the output variable) is a constant multiple of the input variable, such that a point on the graph of ordered pairs of variable is the point (0, 0), which is the origin.

The points on the graph are; (1, 3.5), (2, 4.5), (3, 5,5)

The slope of the graph is therefore; (4.5 - 3.5)/(2 - 1) = 1

The equation in point-slope form is therefore; y - 3.5 = x - 1

y = x - 1 + 3.5 = x + 2.5

y = x + 2.5

The equation is a linear relationship. The equation is in the form; y = m·x + c, with the slope m = 1 and a y-intercept, c = 2.5

The y-intercept is 2,5, therefore, the graph does not pass through the origin.

The relationship of the line passing through the points, is a linear relationship. The line passing through the points does not pass through the origin, therefore the relationship is not a proportional relationship

The correct option is therefore; It cannot be a proportional because the straight line through the points does not go through the origin.

The Law of Sines says that in any given triangle, the ratio of any side length to the sine of its opposite angle is the same for all three sides of the triangle. This is true for any triangle, not just right triangles.

The law of sines relates the ratios of side lengths of triangles to their respective opposite angles. This ratio remains equal for all three sides and opposite angles. We can therefore apply the sine rule to find the missing angle or side of any triangle using the requisite known data.

The ratio of the side and the corresponding angle of a triangle is equal to the diameter of the circumcircle of the triangle. The sine law is can therefore be given as,

[tex]\frac{a}{sin A} = \frac{b}{sin B} = \frac{c}{sin C}[/tex]

In a right triangle, the sine of an angle is the ratio of the length of the opposite side divided by the length of the hypotenuse.

Answer: 2/3

Step-by-step explanation:

To find the probability of A or B, we can use the formula: P(A or B) = P(A) + P(B) - P(A ∩ B)

Plugging in the given values:

P(A or B) = 1/2 + 1/3 - 1/4

To solve this, we must find a common denominator in order to add the fractions:

P(A or B) = 3/6 + 2/6 - 1/6

Simplifying:

P(A or B) = 4/6 = 2/3

So the value of P(A or B) is 2/3

Answer:

The value of x is -19.

Step-by-step explanation:

Given that ZA and B are vertical angles and m/A = (2x +20)°, and m/B = (3x + 1)°, we know that ZA and B are congruent, meaning they have the same measure. We can set the two given equations equal to each other: m/A = (2x + 20)° = m/B = (3x + 1)°. Then, by isolating x on one side of the equation, we subtract 20 from both sides of the equation, then subtract 2x from both sides of the equation, which gives us x = -19, thus the value of x is -19.

Answer:

x = 19

Step-by-step explanation:

since vertical angles are equal we can set the value of angles A and B equal and solve for 'x'

2x + 20 = 3x + 1

20 = x + 1

19 = x

The value of angle x is 45°. Thus, option B is correct.

A corner is an angle if it forms a projecting part or a partially enclosed space. An angle is a figure made up of two lines that extend from the same point. a measurement of an angle or the amount of turning required to align or make parallel two lines or planes.

step1:

o is center

JK is a tangent

so <OKJ =90°

<OKM=90°-30°=60°

OM=OK=><OMK=60°

step2:

because LO=LO, LM=LK, ON=OK

So Triangle OLM ≅ Triangle OLK => <LOM=<LOK

so <LOM=150° => <LMO =15°

so  60° +15° =30°+x°=>x= 45

The ordered pair which describes the location of M''M" is (4, -4).

In Geometry, a reflection over the y-axis is given by this transformation rule (x, y) → (-x, y). This ultimately implies that, a reflection over the y-axis would maintain the same y-coordinate while the sign of the x-coordinate changes from positive to negative or negative to positive.

By applying a reflection over the y-axis to the coordinates of the image coordinates include the following:

(x, y)                               →              (-x, y)

Coordinate M = (-4, 4)   →  Coordinate M' = (-(-4), 4) = (4, 4).

1/6 of the whole garden is planted in cucumber.

What is cucumber ?

Cucumber is a type of vegetable that belongs to the cucurbit family, which also includes melons, squash and gourds. They are typically long, cylindrical in shape, and have a green skin that is typically eaten raw.

The proportion of the garden planted in cucumber is 1/3 of the vegetable part of the garden. To find out what proportion of the entire garden is planted in cucumber, we can use this proportion and multiply it by the proportion of the garden that is planted in vegetables.

Half of the garden is planted in vegetables, so the proportion of the garden planted in vegetables is 1/2.

1/3 of the vegetable part of the garden is planted in cucumber, so the proportion of the garden planted in cucumber is ,

Julio needs to prove that two sides of the two triangles are congruent, in addition to the hypotenuse and one set of legs that are already congruent, to use the SAS Triangle Congruence Theorem.

Julio needs to prove that the two triangles have congruent sides in order to use the SAS Triangle Congruence Theorem. This means that he needs to show that one side of one triangle is congruent to a corresponding side of the other triangle and the same applies to the other two sides. This can be done by using methods such as measuring the sides, using algebraic equations, or using geometric constructions.

According to Julio statement, he has already constructed two right triangles to have congruent hypotenuses and one set of congruent legs, which means he has already proved that one side of one triangle is congruent to a corresponding side of the other triangle (hypotenuse) and one set of legs are congruent.

Therefore, Julio need to prove the remaining side of the triangle congruent to the corresponding side of the other triangle. Once he proves this, he can use the SAS Triangle Congruence Theorem to state that the two triangles are congruent.

To show that one value is greater than another, use the "greater than" symbol (>). It can be used to express a comparison between two values in mathematical operations, programming, and other forms of notation.

   For instance, the "greater than" symbol can be used to compare integers in mathematical operations. For instance, you would write "x > y" to indicate that x is greater than y. This can alternatively be understood as "x exceeds y."

  Other comparison symbols, such as "less than," "greater than," and "less than or equal to," can be used in addition to the "greater than" symbol. These symbols can be used to describe many forms of value comparisons in programming and mathematical processes.
