If the table is not proportional, drag and drop "not proportional" into the box.
The constant of proportion in the proportional relationship is 3/2
What is constant of proportionalityThe constant of proportionality is a value that represents the ratio of two variables in a proportional relationship. The constant of proportionality is represented by the letter "k" in the mathematical equation y = kx, where y and x are the variables in the relationship, and k is the constant of proportionality. It is a fixed value that does not change regardless of the specific values of the variables. The value of k can be determined by dividing the y-value of any point on the relationship by the corresponding x-value of that point.
To determine the constant of proportionality, we have to use the formula;
y = kx
Taking one point from the table;
9 = k(6)
k = 9/6
k = 3 / 2
Taking another point to confirm
3 = k(2)
k = 3/2
The constant of proportionality is 3/2

What are trigonometric functions?
Trigonometric functions are also known as Circular Functions can be simply defined as the functions of an angle of a triangle. It means that the relationship between the angles and sides of a triangle are given by these trigonometric functions. The basic trigonometric functions are sine, cosine, tangent, cotangent, secant and cosecant.
The angles of sine, cosine, and tangent are the primary classification of functions of trigonometry. And the three functions which are cotangent, secant and cosecant can be derived from the primary functions.
Now, To find the trigonometric function from the given graph
we can check by putting values in the functions
As at angle zero degree only sine is zero so 2 and 4 are cancelled
and as cosine at angle of zero degree is 1 but with multiplying it with -1/2 it will be negative.
Hence,

Suppose that a baseball player's long-run batting average (number of hits per time at bat) is. 300. Assuming that each time at bat yields a hit with a consistent probability, independently of other times, what is the chance that the player's average over the next 100 times at bat will be a). 310 or better
The likelihood that the player's average will be.310 or higher during the following 100 at-bats is. 9267
What is meant by probability?A probability is a number that expresses the possibility or likelihood that a specific event will take place. Probabilities can be stated as proportions with a range of 0 to 1, or as percentages with a range of 0% to 100%.
The likelihood of obtaining at least 31 hits in 100 at-bats when the likelihood of getting a hit in each at-bat is.300 must be taken into account in order to calculate the likelihood that the player's average during the subsequent 100 times at bat will be.310 or higher.
The likelihood of obtaining at least 31 hits in 100 at-bats when the likelihood of a hit occurring in each at-bat is.
You may calculate 300 as follows:
P(31 hits or more in 100 at-bats) = 1 - P(30 hits or fewer in 100 at-bats)
When the likelihood of getting a hit in each at-bat is, we can determine the likelihood of getting at least 31 hits in 100 at-bats using the normal approximation. the following 300:
P(31 hits or more in 100 at-bats) = 1 - P(30 hits or fewer in 100 at-bats)
substitute the values in the above equation
= 1 - P(z ≤ (30 - 100(.300)) / √(100(.300)(1 - .300)))
simplifying the equation, we get
= 1 - P(z ≤ -1.44)
= 1 - .0733
= .9267
As a result, there is a roughly.9267 chance that the player's average over his next 100 at-bats will be.310 or higher.

(2/7 * x + 5/8) - (1/6 * x - 3/7)
Answer: To simplify the expression (2/7 * x + 5/8) - (1/6 * x - 3/7), we need to combine like terms.
(2/7 * x + 5/8) - (1/6 * x - 3/7) = (2/7 * x) + (5/8) - (1/6 * x) + (3/7)
= (2/7 * x - 1/6 * x) + (5/8 + 3/7)
= (2/7 - 1/6) * x + (5/8 + 3/7)
= (2/42) * x + (40/56)
Since 2/42 and 40/56 are in lowest terms, this is the simplified expression.
Note that we cannot simplify the expression further unless we know the value of x.

fellix built a ramp based on the scale drawing below. if the height of felix's ramp is 6 inches from the ground, how long is the part of the ramp that is on the ground?
The scale drawing and applying proportion, the length of the part of the ramp that is on the ground is calculated as 72 inches.
In a scale drawing, proportion can be used to find actual measurements.
height of Felix's ramp = 6 inches
height on scale drawing = 1 inches
Length of ramp on the ground = x = ?
length of ramp on scale drawing = 12 inches
Thus, the following proportion can be created:
6 = 1
x = 12
Cross multiply
x = (6×12)/1
x = 72 inches
Therefore, given the scale drawing and applying proportion, the length of the part of the ramp that is on the ground is calculated as 72 inches.

4x + y = -12
x − 5y = -3
help, please
Answer:
x = -3
y = 0
Step-by-step explanation:
4x + y = -12
x − 5y = -3
Times the second equation by -4
4x + y = -12
-4x + 20y = 12
21y = 0
y = 0
Now put 0 back in for y and solve for x
4x + 0 = -12
4x = -12
x = -3
Let's check
4(-3) + 0 = -12
-12 + 0 = -12
-12 = -12
So, x = -3 and y = 0 is the correct answer.
Answer:
(-3,0)
x = -3
y = 0
Step-by-step explanation:
4x + y = -12
x − 5y = -3
Enter the second equation by -4
4x + y = -12
-4x + 20y = 12
21y = 0
y = 0
Now enter 0 for y
4x + 0 = -12
4x = -12
x = -3
Plug that info in
4(-3) + 0 = -12
-12 + 0 = -12
-12 = -12
Therefore x = -3 and y = 0

Find the zeros of the function and explain their meaning within the context of the situation.
The zeros of the given function y = 3p³ – 8p² + 4p are p = 0, p = 2, and p = 2/3
What are the zeros of a function?The zeros of a function are the values of the independent variable (in this case, p) for which the function equals zero.
To find the zeros of the function y = 3p³ – 8p² + 4p, we need to set y equal to zero and solve for p.
y = 3p³ – 8p² + 4p = 0
3p³ – 8p² + 4p = 0
We can factor this as p(3p-2)(p-2) = 0
So, the zeros of the function are p = 0, p = 2, and p = 2/3
In the context of the situation, these zeros represent the values of plastic pollution (p) at which the population size of mackerel (y) reaches 0.

Anyone know the answer? I’ve tried doing the math but I can’t seem to get any of the answers
By understanding the characteristics of an isosceles trapezoid, we can conclude that TQ = 17.4
Trapezoid is a two-dimensional flat shape formed by four sides, two of which are parallel to each other but not the same length. It comes in various forms: arbitrary, right-angled, and isosceles.
Isosceles trapezoid can be characterized as follows:
It has one axis of symmetryIt has a pair of sides that are the same length (the legs)It has two pairs of equal anglesIt has a pair of diagonals that are the same sizeWe are given an isosceles trapezoid with the following information:
ST = 16.1
PR = 33.5
As we know the characteristics of a trapezoid, we can determine:
SQ = PR = 33.5
SQ = ST + TQ
33.5 = 16.1 + TQ
TQ = 33.5 - 16.1
= 17.4

What is the speed of a car which covers a distance of 15 km in 20 minutes?
A scalar quantity known as speed is used to describe "the rate at which an item changes its position" or "the distance travelled in a unit of time." It is a way to gauge how quickly something is moving and is frequently expressed in terms of the amount of space covered in one unit of time, such as miles per hour (mph) or kilometers per hour (km/h). Speed is calculated as follows: speed = distance / time.
Step 1: To determine a car's speed, divide the distance travelled by the time required.
Step 2: In this instance, the journey took 20 minutes and covered 15 kilometers.
Step 3: Divide the number of minutes by 60 to convert it to hours. Therefore, 20 minutes equals 20/60, or 0.333 hours.
Step 4: Now divide the number of kilometers (km) travelled by the number of hours travelled (0.333 hours)
= 15 km / 0.333 hours
=45 km/h
Therefore speed of the car is 45km/hr.
