Answer:
1/4 feet long should each pieces be.
Step-by-step explanation:
Unit rate defined as the rates are expressed as a quantity of 1 such as 3 miles per second or 4 km per hour
As per the statement: Becky has a board that is 2 and 3/4 feet long.
⇒ Length of a board = 
feet
Also, she need to cut the board into 11 pieces.
by unit rate definition:
or
Therefore, 1/4 feet long should each pieces be.

Answer:</h3>
The real solutions are -5, -4, 4, 5. There are no complex solutions.
<h3>
Step-by-step explanation:</h3>
The equation ...
... x^4 -41x^2 +400 = 0
can be factored as ...
... (x^2 -16)(x^2 -25) = 0
... (x -4)(x +4)(x -5)(x +5) = 0
So, all roots are real and are ...
... x ∈ {-5, -4, 4, 5}
_____
These are the values of x that make the factors zero.
Answer:
The experimental probability P(E) is 0.1818 = 18.18%
Step-by-step explanation:
The experimental probability is the number of desired outcomes divided by the number of total outcomes.
In this question:
11 trials(11 outcomes)
2 kings(2 desired)
So
P(E) = 2/11 = 0.1818
The experimental probability P(E) is 0.1818 = 18.18%
(1, 2)
plug 1 in for x and 2 in for y
2x1=2 is 2=2
