3 residents enter an elevator in an apartment complex at the ground floor. They each press a button 1-10 (each resident presses
1 answer:
Answer:
The answer is %2,4
Step-by-step explanation:
Residents can press on 10 different button choice when they enters the elevator. Number of components for the sample space for the event is
There are 8 different possibilities that 3 consecutive buttons are pressed those are:
-1,2,3
-2,3,4
-3,4,5
-4,5,6
-5,6,7
-6,7,8
-7,8,9
-8,9,10
When the pressing order doesn't matter, those buttons can be pressed 3 different ways for each possibility.
The probability is:

Answer:
2x^2-x+3
Step-by-step explanation:
Answer:
When we have a function like:
This function will have a discontinuity only if it diverges, and a divergence can happen when the denominator is equal to zero and the numerator is different than zero.
In this case, we have the equation:
Here the denominator is:
h(x) = x + 2
This is equal to zero when:
x + 2 = 0
x = -2
Now we need to see what happens with the numerator when x = -2
g(-2) = (-2)^2 + 2*(-2) = 0
Is equal to zero.
Then we need to see the limit when x -> -2, and use the L'Hopital theorem.
Because we have zero over zero at that point, we need to look at the quotients of the derivatives of both numerator and denominator.
Then the function does not diverge, then the function has no discontinuity.
We also could look at the graph of f(x) to see it:
Our function is a linear function, and this is because the numerator is x times the denominator, then the function is:
f(x) = x.

Given: The area of a square field is 841 sq.m
Since side of square = √Area
So, side of square field =
Thus , side of square field = 29 m
Perimeter of square = 4( side) = 4(29) = 116 m
Let x be the breadth of rectangle then 2x be the length
Perimeter of rectangle = 2 (length+breadth) = 2(2x+x)= 2(3x)=6x
As per question, perimeter of rectangle= Perimeter of square
Length :
Area of rectangle = length x breadth
Area of rectangle =
