Answer:
The percent error is 40%.
Step-by-step explanation:
5 (actual time) - 3 (estimated time) = 2
2 divided by 5 (actual time) = 0.4
0.4 x 100 = 40%
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:
the perimeter is 36
Step-by-step explanation:
Answer:
1/5
Step-by-step explanation:
The stick has a length of 5 units
The stick is broken at two points chosen at random
First break: the probability that you get a piece that is 1 unit or longer than 1 units= 1/5.
Second break, the probability that you get a piece that is 1 unit or longer than 1 units is 1/5.
Therefore,
The total probability =probability of first break * probability of second break * original stick unit
=1/5 * 1/5 * 5
= 1/25 *5
=5/25
=1/5
