You have to substitute the values for x and y to get the other output. When I put 0 into the equations I get back 0

The value of x and y in the triangle given are 15 and 4 respectively

An Equilateral triangle is a triangle in which all three sides are equal and angles are also equal. The value of each angle of an equilateral triangle is 60 degrees therefore, it is also known as an equiangular triangle. The equilateral triangle is considered as a regular polygon or a regular triangle as angles are equal and sides are also equal.

In the triangle given, we can equate equal sides and find the missing sides on the triangle.

12/18 = y + 12 / 18 + 6

12/18 = y + 12 / 24

2/3 = y + 12 / 24

solve for y

y = 4

Taking another side and solve for x

12 / x = 12 + y / x + 5

but y = 4

12 /x = 12 + 4 / x + 5

12/x = 16 / x + 5

x = 15

The proportion of heads after the first 10 tosses of a coin is zero i.e 0/10 = 0

A probability is a number that reflects the likelihood or probability that a particular event will occur. Probabilities can be expressed as percentages ranging from 0 to 1, and can also be expressed as percentages ranging from 0% to 100%. A probability of 0 indicates that the particular event is unlikely to occur, and a probability of 1 indicates that the event will definitely occur.

Probability is calculated by dividing the number of ways the event can occur by the total number of outcomes.

We have given the following points ,

A coin is tossed 10 times and it comes with tail in each time of first 10 tosses.

When a coin is toosed , there two possibilities either it comes with head or tail. Both can't be come at once.

As we see first ten tosses of a coin gives tails as a result . Then, there is no chance of occurrence head in first 10 tosses.

So, there in no heads in first 10 tosses. The probability or proportion of heads after the first 10 tosses is 0/10 = 0..

Probability works not by compensating for imbalances but by overwhelming them. Suppose that the first 10 tosses of a coin give 10 tails and that tosses after that are exactly half heads and half tails.

The domain of the given function y = 2√(x - 6)

In Mathematics, a domain can be defined as the set of all real numbers for which a particular function is defined.

This ultimately implies that, a domain is the set of all possible input numerical values or numbers (x-values) to a function and the domain of a graph comprises all the input numerical values which are located on the x-coordinate.

In order to determine the domain of this function, we would equate the x-value to zero and then evaluate as follows:

x - 6 ≥ 0

x ≥ 6

Therefore, the domain of this function in interval notation is [6, ∞] as shown in the graph attached below.

Answer: -1/3

Step-by-step explanation:

The formula for slope =y1-y2/x1-x2. You first subtract the numbers for the y coordinate which is -6-(-5), and thats -1. Then you subtract the x coordinates. -6-(-9)=3. So the slope is -1/3

The value of y is 11.

That quadrilateral in which opposite sides are parallel is called a parallelogram.

Thus, a parallelogram is always a quadrilateral but a quadrilateral can or cannot be a parallelogram.

Given that Parallelogram ABCD is a rectangle.

Consider that AC and BD are opposite sides. In a parallelogram, we know that opposite sides are congruent which means:

AC = BD

2y + 7 = 3y - 4

Solving;

2y - 3y = -4 - 7

-y = -11

y = 11

The require angle, angle ABD = 40 degrees

A bisector has two primary characteristics:

Any point along an angle's bisector is equally - spaced from the angle's sides.

The angle bisector divides the other side of a triangle in proportion to the other two sides.

Given : ∠ ABC is bisected by a ray BD

∠ ABC = 80°

Since the angle ABC is being bisected this means that the angles are equal

Let the bisected angle be x

thus we can write it mathematically as

x + x = 80

Answer:

The graph is a function.

Step-by-step explanation:

Answer:

Option B is perpendicular to y=-3x+4 and goes through point (-1,5)

Step-by-step explanation:

We will look for an equation of the form y=mx+b, where m is the slope and b the y-intercept.  The reference line, y=-3x+4, has a slope of -3.  A line perpendicular to this line will have a slope that is the "negative inverse" of the refence lines slope.  In this case, it's slope would be +(1/3).

We could graph each of the equation options and look for one that is perpendicular, but it might be faster to simply rearrnaged the options into standard format of y=mx+b. which we'll do here:

Option   Rearranged Equation   Slope

A) 3y=-x+16

                  y = -(1/3)x+(16/3)           -(1/3)

B) 3y=x+16

                   y = (1/3)x + (16/3)         (1/3)

C) y=-3x+8                                           -3

D) y=-3x+2                                            -3

There is only one option that has the required slope to be parallel to the reference equation (y=-3x+4), option B:  y = (1/3)x + (16/3)

Does it go through point (-1,5)?

y = (1/3)x + (16/3)

Enter x = -1 and find 5:

y = (1/3)(-1) + (16/3)

y = (16/3)-(1/3)

y = (15/3) or 5

 Yes, it goes through point (-1,5)

Option B is perpendicular to y=-3x+4 and goes through point (-1,5).

Here, we have

Jodie aimed to beat Mandy's 74.6-second mark on the obstacle course. She had already spent 10.56 seconds on the ropes and fifty-and-a-fourth seconds ascending the wall. To match the record, we must determine how much time she had remaining.

Jodie's total time for climbing the wall is fifty and one fourth seconds=50.25 seconds

The total time on ropes is 10.56 seconds

The total time she spent is 50.25+10.56=60.81

Left time = Record Time-Spent time

The alternative to random sampling is called as systematic sampling which is accepted by a pollster to poll every 10th person that comes out of a store.

Systematic sampling is a probability sampling technique where researchers choose individuals from the population at predetermined intervals (or k).

This method will provide you with a representative sample that can be used to make generalizations about the population if the order of the population is random or random-appearing (for example, alphabetical).

Simple random sampling has numerous advantages over systematic sampling in terms of randomization, but systematic sampling is a little bit simpler to carry out.

Similar to basic random sampling, systematic sampling can be used with a list of the complete population. Contrary to basic random sampling, one can still utilize this technique if you don't have access to a list of the population beforehand.

The function's y = 3(x + 5)² +11 width will be narrower.

In mathematics, a function from a set x to a set y assigns each element of x precisely one element of y. The subsets x and y are referenced to as the function's domain and codomain, correspondingly. A relationship between a number of inputs and one output per input is referred to as a function. Simply described, a function is an association between inputs in which each piece of data is connected to exactly one output. There is a domain and a codomain, or range, for every function. A function is a type of rule that produces one output from one input. y = x² is a good illustration of this. Any information for x yields a single output for y.

A parabola is made narrow by a large positive value of a and wide by a large positive value of a that is close to 0.

Compare the given equation y = 3(x + 5)² + 11 with y = x² + c

So, a = 3

Therefore, the function will be narrower.
