oncluded that the equation must have no solution. Is the student correct? Explain. A. The student is correct. When variables are eliminated from an equation, the equation must have no solution. B. The student is incorrect. When variables are eliminated from an equation, the equation must be an identity and therefore has infinitely many solutions. C. The student is correct. When variables are eliminated from an equation, the equation must be an identity and therefore has infinitely many solutions. D. The student is not necessarily correct. The integers on each side of the equation could be equal, so the equation has infinitely many solutions.

What is the measure of an angle that is it’s own complement ?
ValentinkaMS [17]

A complement is angle that can be added to another to equal 90 degrees.

So two times the same number would equal 90.

90 / 2 = 45

The angle that is its own complement is 45 degrees.

Ginger buys lunch at school every day. She always gets
shepuryov [24]

Answer:

The estimated probability that Ginger will eat a a pizza everyday of the week is;

D. 8/10 = 80%

Step-by-step explanation:

The given parameters are;

The frequency with which Ginger buys launch = Everyday

The percentage of the time the cafeteria has pizza out = 80%

The outcome of 0 and 1 = No pizza available

The outcome of 2, 3, 4, 5, 6, 7, 8, and 9 = Pizza available

Therefore, we have the;

Group number  {}                          Percentage of time pizza available

1                     {}                          80%

2                     {}                          80%

3                     {}                          80%

4                     {}                          80%

5                     {}                          40%

6                     {}                          100%

7                     {}                          80%

8                     {}                          100%

9                     {}                          80%

10                     {}                          80%

Therefore, the sum of the percentages outcome the days Ginger eats pizza = 0.8 + 0.8 + 0.8 + 0.8 + 0.4 + 1 + 0.8 + 1 + 0.8 + 0.8 = 8

The number of runs of simulation = 10 runs

The estimated probability that Ginger will eat a a pizza everyday of the week = (The sum of the percentages outcome the days Ginger eats pizza)/(The number of runs of simulation)

∴ The estimated probability that Ginger will eat a a pizza everyday of the week = 8/10
