The constant of proportionality is 10 in the given graph which represents the total number of plants and number of seed packets used.
What is proportionality?Equivalence between two ratios is referred to as proportionality in algebra. A and B are in the same proportion as C and D in the expression a/b = c/d. When one of a proportion's four quantities is unknown, a proportion is typically used to solve a word problem.
It is resolved by multiplying one numerator by the opposing denominator and equating the result to that of the other numerator and denominator. Any relationship that always has the same ratio is referred to as proportional.
For instance, the ratio of proportionality is the average number of apples per tree, and the quantity of apples in a crop is proportional to the number of trees in the orchard.
Here, when number of seeds packet is 1 plants are 10 and when seeds packet are 5 plants are 50, we can divide each of the variables to find the constant,
10/1 = 10
20/2 = 10
30/3 = 10
Thus, constant is 10 represented as y = kx
where y = no. of plants = 30
k = 10
x = no. of seeds packet = 3

The distinction among rational numbers as well as fractions is that fractions cannot include a negative denominator or numerator. As a result, the numerator and denominator of the a fraction are all numbers (denominator 0), whereas the numerator and denominator of rational numbers are integers.A rational number, p/q, is considered to be in standard form if its numerator and denominator (p and q) share no common divisor (or factor) other than 1 and its denominator "q" is positive.For the given number-
π, 5/4, -8, 2.35 bar, 19/7, 8, 0
All numbers except π are rational as they are either ending number or have the bar which means they will repeat after some point.
π is the only number which have the value 3.14........and so o such that, it is nether terminating nor repeating.
Thus, π is the irrational number.
Therefore, rational numbers are- [5/4, -8, 2.35 bar, 19/7, 8, 0]

customers arrive at a checkout counter in a department store according to a poisson distribution at an average of seven per hour. what are the probabilities that
From the information given in the Poisson Distribution, the probability that that no more than three customers arrive that is P (X≤3) = 0.0817.
What is a Poisson Distribution?
The Poisson distribution is a discrete probability distribution in probability theory and statistics that articulates the likelihood of a specific number of events happening in a fixed interval of time or space if these events occur with a particular frequency mean rate and regardless of the time since the last event.
What Are the Poisson Distribution's Assumptions?
To be correct, all events must be independent of one another, the pace of occurrences must be steady across time, and events cannot occur concurrently. Furthermore, the mean and the variance will be equal.
What is the justification for the above result?
According to a Poisson distribution, seven people come at a checkout counter in a department store every hour on average. i.e λ=7
Probability (P) that no more than three customers arrive is notated as P(X≤3)
= P(X=0) + P(X=1) + P(X=2) + P(X=3)
= Poisson (3,7,1)

Answer:
u=11
Step-by-step explanation:
7u-12u+17=-38-combine like terms
-5u=-38-17
-5u=-55
-u=-11
which means u=11
Answer:
u = 11
Step-by-step explanation:
7u + 17 - 12u = - 38 , that is
- 5u + 17 = - 38 ( subtract 17 from both sides )
- 5u = - 55 ( divide both sides by - 5 )

Diana severs breakfast to two groups of children at a daycare center. One box of Oaties contains 12 cups of cereal. She needs ⅓ cup for each younger child and ¾ cup for each older child. Is one box of Oaties enough for everyone
One box of oaties will be enough for two groups of children.
We can state the box of oaties is enough for everyone, if the amount required by number of children in each group is less than or equal to 12.
So, amount of cereal required by younger/older children = amount required by one child × number of children
Amount of cereal required by younger children = 1/3 × 11
Amount of cereal required by younger children = 11/3 cups of cereal
Amount of cereal required by older children = 3/4 × 10
Amount of cereal required by younger children = 15/2 cups of cereal
Amount of cereal = 12 - (11/3 + 15/2)
Taking LCM in the bracket, we get 6
Amount of cereal = 12 - (11×2 + 15×3/6)
Solving the bracket
Amount of cereal = 12 - (22 + 45/6)
Performing addition = 12 - (67/6)
Amount of cereal = (12×6 - 67)/6
Amount of cereal = 72 - 67/6
Performing subtraction in numerator
Amount of cereal = 5/6
As 5/6 cups of cereal is remaining, thus, a box of oaties will be enough for 11 younger children and 10 older children.

The ordered pair for A' is (4, 0).The ordered pair for B' is (7, 2).The ordered pair for C' is (9, 9).What is a rotation?A rotation can be defined as a type of transformation which moves every point of the object through a number of degrees around a given point, which can either be clockwise or counterclockwise (anticlockwise) direction.
In Geometry, rotating a point 180° about the origin in a clockwise or counterclockwise (anticlockwise) direction would produce a point that has the coordinates (-x, -y).
By applying a rotation of 180° counterclockwise (anticlockwise) to triangle ABC, the coordinate of the image of triangle A'B'C' is given by:
(x, y) → (-x, -y)
Points at A = (-4, 0) → Points at A' = (-(-4), -(0)) = (4, 0)
Points at B = (-7, -2) → Points at B' = (-(-7), -(-2)) = (7, 2).
Points at C = (-7, -2) → Points at C' = (-(-9), -(-9)) = (9, 9).

Find the Standard deviation of 2, 2.6, 3.2, 4.3 5, 4.7, 6.2
The most appropriate choice for standard deviation will be given by-
Standard deviation is 1.41
What is Variance and standard deviation?
At first, it is important to know about mean of a data.
Mean gives the average value of the data.
Variance is calculated by taking the sum of the square of deviation of each value of the data set and then dividing the sum by the total number of values of the data set.
On taking the square root of the variance, we will obtain the standard deviation of the data set.
Here,
The data set is 2, 2.6, 3.2, 4.35, 4.7, 6.2
Mean = [tex]\frac{2 + 2.6 + 3.2 + 4.35 + 4.7 + 6.2}{6}[/tex]
= 3.84
Variance = [tex]\frac{(2-3.84)^2+(2.6-3.84)^2+(3.2-3.84)^2+(4.35-3.84)^2+(4.7-3.84)^2+(6.2-3.84)^2}{6}[/tex]
= [tex]\frac{11.9021}{6}[/tex]

Prove: m<1 +m<+m<3 = 360
Sum of Exterior Angles of Triangle is 360°.
Define Exterior Angle
The angle between any side of a shape and a line that extends from the next side is known as the exterior angle.
Let's Prove: ∠1 + ∠2 + ∠3 = 360°
The angle that is created between one of a triangle's sides and its adjacent extended side is known as the external angle. A triangle has three external angles. Let's learn about the equation for adding a triangle's exterior angles.
From the figure, we can observe that ∠1, ∠2, and ∠3 are the exterior angles of triangle ABC. We know that the sum of all the exterior angles of any polygon is equal to 360°.
Thus, sum of all the exterior angles of a triangle = 360°

Step-by-step explanation:
a + b - 8 = p solve for a
a + b - 8 = p
subtract b from both sides:
a + b - 8 - b = p - b
a - 8 = p - b
add 8 to both sides:
a - 8 + 8 = p - b + 8
a = p - b + 8

a = −b + p + 8
Answer:
a = p + 8 - b
