Answer:
The possibility is 1/4, with 1 representing both coins tails up, and the 4 representing all the outcomes possible.
Step-by-step explanation:
Let
be the amount of parts the student answered correctly. Suppose that
is a function between
and the score of a student's project. As the student initially receives a fixed
points for turning the project in and
points for each correct part, the function is initially:
When the students receive
points for each correct part, the coefficient of
changes, as the amount of points received per correct answer increases. Thus:
.
Answer:
Put another dot on 79

Because the plot shows that 79 must have 4 dot.So you need to add one more dot
Answer:
5 + 3.5h = 29.50
Step-by-step explanation:
The flat fee means that you will be paid the money with no change to it.
So you will not multiply it.
3.5h means that you are adding 3.50 every hour according to the question
So summary:
5+3.5h = 29.50
Evaluation:
5+3.5h = 29.50
24.50 = 3.5h
h = 7

Answer:
x = 4 is the solution
Step-by-step explanation:
given = x ( square both sides )
x + 12 = x² ( rearrange into standard form )
x² - x - 12 = 0 ← in standard form
(x - 4 )(x + 3 ) = 0 ← in factored form
equate each factor to zero and solve for x
x - 4 = 0 ⇒ x = 4
x + 3 = 0 ⇒ x = - 3
Insert these values into the original equation, and if both sides are equal, and those are the solutions.
x = 4 : = = 4 = x ← correct
x = - 3 : = = 3 ≠ - 3 ← false
the answer is x = 4
