Th relationship between Jose's age and Mario's age can be modelled as a linear equation. A linear equation is an equation that when graphed is a straight line. The straight line can either slope upward or downward.

A linear equation is an equation that increases at a constant rate. It has a single variable that is raised to the power of one.

Looking at the table, there is a proportional relationship between  Jose's age and Mario's age.

The equation is d = 3m + 5

What is an equation?

An equation is a formula in mathematics that expresses the equivalence of two expressions by linking them with the equals symbol =. The word equation and its cognates in various languages may have somewhat different definitions; for example, in French, an équation is defined as including one or more variables, but in English, an equation is any well-formed formula consisting of two expressions linked by an equals sign. Solving an equation with variables entails finding which variables' values make the equality true. The variables for which the equation must be solved are also known as unknowns, and the values of the unknowns that fulfill the equality are known as equation solutions. Identity equations and conditional equations are the two types of equations.

The cost function is given by the equation d = 3m + 5

F. Dilations of an angle are congruent to the original angle.

In Geometry, there are different types of transformation and these include the following:

Dilation simply refers to a type of transformation which changes the size of a geometric object, but not its shape. This ultimately implies that, the size of the geometric object would be increased or decreased based on the scale factor used.

In this context, we can reasonably infer and logically deduce that a dilation of perpendicular lines would always remain perpendicular lines because it takes each of the line to another perpendicular line.

What is distance?

Distance is how much ground travelled by an object during its motion.

Here,

For River Edge

Number of animals seen = 8

Length of hike =  3 km

Number of Animals seen per km = 8/3

                                                      =2.66

For Wooden Marsh

Number of animals seen = 24

Length of hike =  8 km

Number of Animals seen per km = 24/8

                                                       =3

For Canyon Creek

Number of animals seen = 35

Length of hike =  15 km

Number of Animals seen per km = 35/15

                                                      =2.33

Area of rectangular park = [tex]50 \times 30[/tex]

                                         = [tex]1500[/tex] [tex]m^2[/tex]

Length of rectangular park with safety zone = (x + x + 50) m

                                                                         = (2x + 50) m

Breadth of rectangular park with safety zone = (x + x + 50) m

                                                                         = (2x + 30) m

Step-by-step explanation:

6C3 = 6! / ( 3! * 3!) = 20 COMBOS

Answer: 1.28

Step-by-step explanation:

1. P(Z > 0.99) = 1 -Ф (0.99) = 1-0.8389 = 0.1611

2.P(Z <-0.99) = Ф(-0.99) = 0.161 (known that from [a] by symmetry)

3.P(Z <0.99) = Ф(0.99) = 0.8389

4. P(Z >0.99) = P(Z <-0.99) + P(Z > 0.99) = 2(0.1611) = 0.3222

The value z = 10.0 is out because it is too large. On comparing with the largest value, z = 3.99,

we get

5. P(Z < 10.0) > P(Z <3.99) = 1.0

6.P(Z > 10.0)<P(Z > 3.99) =10.0

7. On solving the equation

Ф(Z) = 0.9

for Z.

In Table A4, find the value of z corresponding to the probability 0.9. The  nearest value is Ф(1.28) = 0.8997. Therefore, z ≈ 1.28

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)

So, we want a graph with a closed circle at 2 with the arrow pointing to the right.

Answer:

2nd choice

Step-by-step explanation:

6x - 2 ≥ 10

add 2 to both sides

6x - 2 + 2 ≥ 10 + 2

6x ≥ 12

divided b0th sides by 6 to get x alone

6x/6 ≥ 12/6

x ≥ 2

x is greater than or equal to 2

equal to 2 is shown by a shaded in circle (cannot be option 3 or 4)

x is bigger than 2 so the arrow is to the right

y - 9 = 2( x - 5). Thus, option (1) is the answer.

The point-slope form is a method that uses the slope of the line and a random coordinate on any point of the line to create an equation of that line.

The equation in the point-slope form is written in the format: [tex]y-y_{1}=m(x-x_{1})[/tex] , where m is the slope and [tex]x_{1}[/tex] and [tex]y_{1}[/tex]are the coordinates of the point on the line.
