Commutative property is "a + b = b + a"

Therefore your answer is 1. 5 + 6 = 6 + 5

Answer:

1.5+6=6+5

Step-by-step explanation:

We have to find the equation which represents the commutative property of addition.

Commutative property of addition:Let a and b are two integers satisfied the commutative property of addition , then

a+b=b+a

1.5+6=6+5

5+6=11

6+5=11

Hence, 5+6=6+5.

Therefore, it is an example of commutative property.

2.2+(4+6)=(2+4)+6

Associative property of addition : a+(b+c)=(a+b)+c

Hence, it represents the associative property of addition not commutative property of addition.

3.3\times 8=8\times 3

It represents the commutative property of multiplication.

Associative property of multiplication:a\times b=b\times a

4.10+3=7+6

It does not satisfied the commutative property of addition.

Hence, option 1 is true.

The table shows the numbers y of students absent from school x days after a flu outbreak.

  1. A function that models the data is given by this quadratic equation, y = -0.4908x² + 5.8845x + 1.3572.
  2. The number of students that are absent 10 days after the outbreak is equal to 11 students.

<h3>What is a scatter plot?</h3>

A scatter plot can be defined as a type of graph which is used for the graphical representation of the values of two (2) variables, with the resulting points showing any association (correlation) between the data set.

<h3>What is a quadratic function?</h3>

A quadratic function can be defined as a mathematical expression (equation) that can be used to define and represent the relationship that exists between two or more variable on a graph.

In Mathematics, the standard form of a quadratic equation is given by;

ax² + bx + c = 0

By critically observing the graph (see attachment) which models the data in the given table, we can infer and logically deduce that the quadratic function is given by:

y = -0.4908x² + 5.8845x + 1.3572

For the number of students that are absent 10 days after the outbreak, we have:

y = -0.4908(10)² + 5.8845(10) + 1.3572

y = -0.4908(100) + 58.845 + 1.3572

y = -49.08 + 58.845 + 1.3572

Number of students, y = 11.12 ≈ 11 students.

Which equation could represent the relationship shown in the scatter plot?
Allisa [31]
Y = mx + b, where m is the slope, and b is the y-intercept. If we were to consider a line of best fit that would represent all these points with a linear line, it'd cross the y-axis with a y-value of 10, so we can fill in y = mx + b to y = mx + 10. Now, it runs down from left to right, so we know the slope must be negative. The only equation that fits this description is y= -3/4x + 10
