Answer:
1/36
Step-by-step explanation:
A dice have 6 faces, each face have 1/6 chance to land on, so the chance of landing on 3 two times in a row is 1/6 x 1/6 = 1/36
Answer:
nbr2 = 0
Step-by-step explanation:
Given
The following program segment
<em>nbr2 = 0 </em>
<em>calc = 1 </em>
<em>x= 7 </em>
<em>while x >=3: </em>
<em> calc = calc * x </em>
<em> x = x - 2</em>
<em />
Required
The value of nbr2
In the first line, nbr2 was initialized to 0 i.e.
<em>nbr2 = 0</em>
<em />
From the second line of the program till the last, no operation was carried out on nbr2
This means that nbr2 will maintain its original value (which is 0)
Hence,
<em>The value of nbr2 is 0</em>
Answer:
(x-1) (x+4)^2
Step-by-step explanation:
1 goes into the function as it gives a remainder 0.
Then use synthetic division and it gives x^2+8x+16
Looking at that, root of 16 is 4 meaning (x+4)^2
I: x-3*y=12
II: 2*x+6*y=60
add I*2 to II:
2*(x-3y)+2x+6y=2*12+60
2x-6y+2x+6y=24+60
4x=84
x=21
insert x=21 into I:
21-3y=12
9-3y=0
9=3y
3=y
is the only solution (21,3), sou you probably have another option which you didn't copy :)
