The mean of on road accidents reported to the police for the days in December is 6.7
What is the meaning of mean ?In a group of numbers, the mean is the average or most common value. It is a measure of central tendency of a probability distribution along the median and mode in statistics.
It is given in the question about the information on road accidents reported to the police for the days in December.
Mid point of (0-5) = 2.5
Mid point of (6-10) =8
Mid point of (11-15)=13
Mid point of (16-20) = 18
Mean = (∑Midpoint * frequency )/ (∑ frequency)
[tex]\rm Mean = \dfrac{2.5\times18+8 \times4+13\times6+18\times3}{18+4+6+3}\\\\\\\rm Mean = \dfrac{209}{31}\\[/tex]
Mean = 6.74
Mean = 6.7

List the steps for developing a model.
Answer:
This is for mathematical modeling. . .
Step-by-step explanation:
Mathematical Modeling-
There are four steps to mathematical modeling:
1. Identify the problem and develop a well-defined question.
2.Look for relations and connections between the variables that are involved.
3. Translate features and relationships you have identified into a mathematical model
4. Verify that the mathematical model accurately represents the situation under investigation.
Priya bought these items at the grocery store. Find each unit price. A. 12 eggs for $3. How much is the cost per egg? B. 3 pounds of peanuts for $7.50. How much is the cost per pound? C. 4 rolls of toilet paper for $2. How much is the cost per roll? D. 10 apples for $3.50. How much is the cost per apple?
Answer: A. Cost per egg = $4 .
B. Cost per pound = $ 2.5
C. Cost per roll = $ 0.5
D. Cost per apple = $0.35
Step-by-step explanation:
Formula: cost per item = (total cost) ÷ (number of items)
A. 12 eggs for $3.
Cost per egg = $ (12÷3) = $4
So, Cost per egg = $4 .
B. 3 pounds of peanuts for $7.50
Cost per pound of peanuts = $ (7.50 ÷ 3)= $ 2.5
So, Cost per pound = $ 2.5
C. 4 rolls of toilet paper for $2.
Cost per roll = $ (2 ÷4 ) = $ 0.5
So, Cost per roll = $ 0.5
D. 10 apples for $3.50.
Cost per apple = $ (3.50 ÷ 10)= $ 0.35
So, Cost per apple = $0.35

Consider the graph and equation, y = 3x, that represent Alonso’s walking speed. What relationship is represented by this equation and graph? What would the points (3, 9) and (5, 15) represent? Explain.
Answer:
The equation, y=3 x,
Step-by-step explanation:
y=Distance traveled
x =Total time
Also, in terms of straight line
Slope =3= uniform Velocity
Point (3,9) and (5,15) represents Distance traveled in 3 (unit of time) =9 unit, and 15 unit=Distance traveled in 5 (Unit of time).
→Alonso is moving with uniform speed=3 (unit of time), as velocity remains constant in the entire process.
Answer:
The equation y = 3x represents a proportional relationship, where y represents distance in miles, and x represents time in hours. The point (3, 9) represents that Alonso walks 9 miles in 3 hours. The point (5, 15) represents that Alonso walks 15 miles in 5 hours.

Step-by-step explanation:
Write the equation of a line in slope-intercept form with a slope of -1 and a y-
intercept of -1.
y = -x - 5
y = -5x - 1
y = -x-1
y= -5x -5
Answer:
y = -x - 1
Step-by-step explanation:
Slope intercept form is y = mx + b, where m is the slope and b is the y intercept.
Plug in the slope and y intercept into the equation
y = mx + b
y = -x - 1 is the equation in slope intercept form
Answer:
y = -x - 1
Step-by-step explanation:
Slope intercept form is y = mx + b, where m is the slope and b is the y intercept.
Plug in the slope and y intercept into the equation
y = mx + b
y = -x - 1 is the equation in slope intercept form
