Answer:

  1. Mean score=120

Step-by-step explanation:

  1. Areas of a triangle add upto 180degrees (63+78+x=180) 141+x= (x=180-141) x=39
  2. Areas on a straight line add upto 180degrees

180-78=102

180-63=117

180-39=141

  1. 102+117+141=360
  2. Mean=360/3 =120

12. The table shows the number of people who attended a
Nataly_w [17]

Answer:

1. See the graph attached

2. 13,400 thousands people will attend the new movie on the 8th day, if the pattern shown in the graph continues.

Explanation:

The <em>table </em>that shows the number of people who attend a new movie ofver teh course of a week is:

Day   Attendance (thousands)

1          12,200

3         12,600

5         13,000

7         13,400

8              x

The <em>graph</em> showing that pattern is attached.

It is a discrete graph because days can take only positive integer values.

You can see that the relation is linear and can calculate the change in the number of people every two days by subracting any two consecutive pairs of data:

  • 12,600 - 12,200 = 400
  • 13,000 - 12,600 = 400
  • 13,400 - 13,000 = 400

Hence, every two days the increase in the number of people is 400 thousands.

For one day the increase is: 400 thousands / 2 days = 200 thousands/day.

Since you know the attendance for the day 7, you can calculate the attendance for the day 8 adding 200 thousands to 13,400:

  • 13,400 thousands + 200 thousands = 13,600 thousands.

Cerrena [4.2K]

16t

• In mathematics, algebraic equation is the statement of equality of two expressions formulated by applying to a set of variables the algebraic operations, namely, addition, subtraction, multiplication, division, raising to a power, and extraction of a root.

• Algebra is divided into different sub-branches such as elementary algebra, advanced algebra, abstract algebra, linear algebra, and commutative algebra.

• Whatever is on one side of the equal sign must have exactly the same value on the other side else it becomes an inequality.

Algebraic equations are of various types. A few of the algebraic equations are:

• Polynomial Equations

• Quadratic Equations

• Cubic Equations

• Rational polynomial Equations

• Trigonometric Equations

The expression  the product of 16 and the time after the start represent the algebraic equation 16t
