Answer:
Integers, Terminating Decimals, Recurring Decimals, Proper and Improper Fractions.
Step-by-step explanation:
The following subset of the real number system can be written in the form , b≠0.
Integers(ℤ): These are positive and negative whole numbers. For example, 5 can be written as
Terminating Decimals: These are fractions that when converted to decimal numbers have an end.
e.g.
Recurring Decimals: These are fractions that when converted to decimal numbers do not have an end.
e.g.
Proper Fractions: These are fractions of the form where a<b. An examples is
Improper Fractions: These are fractions of the form where a>b. An examples is
Answer:
Simple linear equation is :
Y = 86.784 - 2.67x
Step-by-step explanation:
The educator wants to see the relationship between no of absences and final grades of the student. No. of absence of student is independent variable while final grade is dependent variable. The final grades of the student are dependent on the no. of absence they do.
b = Sxy / Sxx
b = { 2312 [ 37 * 422 ] / 6 } / 337 - 37^2 / 6 = -2.67
a = -2.67 * 37/6 = 86.784
The average rate of change of a continuous function <em>f(x)</em> in an interval (<em>a</em>, <em>b</em>) is
(<em>f(b) </em>- <em>f(a)</em>) / (<em>b</em> - <em>a</em>)
So for
<em>f(x)</em> = 3<em>x</em> ² + 2<em>x</em> + 5
on the interval (0, 2), we have
• <em>f</em> (2) = 3 • 2² + 2 • 2 + 5 = 21
• <em>f</em> (0) = = 3 • 0² + 2 • 0 + 5 = 5
so that the average rate of change is
(<em>f</em> (2) - <em>f</em> (0)) / (2 - 0) = (21 - 5) / 2 = 16 / 2 = 8
and the answer is B.

Answer:
Triangle = 5
Circle = 25
Square = 100
Pentagon = 1600
Rectangle = 155
Step-by-step explanation:
6 x triangle = 3 x 10
Solve for 3 x 10
6 x triangle = 30
Divide both sides by 6
Triangle = 5
•••••••••••••••••••••••••••••••
Triangle x 20 = Circle x 4
Substitute triangle for 5
5 x 20 = Circle x 4
Solve for 5 x 20
100 = Circle x 4
Circle = 100 divided by 4
Circle = 25
•••••••••••••••••••••••••••••••
Circle + triangle = square minus 70
Substitute Circle and Triangle for their values
25 + 5 = square - 70
Solve for 25 + 5
30 = square - 70
Add 70 to both sides
square = 100
•••••••••••••••••••••••••••••••
Square x 8 = 1/2 of pentagon
Substitute square for 100
100 x 8 = 1/2 of pentagon
Solve for 100 x 8
800 = 1/2 of pentagon
Pentagon = 1600
•••••••••••••••••••••••••••••••
Pentagon divided by square = rectangle + 5
Substitute pentagon and square for their values
1600 divided by 100 = rectangle + 5
Solve for 1600 divided by 100
160 = rectangle + 5
Subtract 5 from both sides
Rectangle = 155
••••••••••••••••••••••••••••••••••
Rectangle x rectangle = ?
Rectangle = 155
Rectangle x rectangle = 24025
