Answer:
the probability that this employee belongs to group I is 0.2118
Step-by-step explanation:
Given the data in the question;
P( group 1 ) = 0.20
P( group 11 ) = 0.60
P( group 111 ) = 0.20
now
= 0.10
= 0.90
= 0.20
= 0.80
= 0.05
= 0.95
so
= [ × P( group 1 ) ] / [ × P( group 1 ) + × P( group 11 ) + × P( group 111 ) ]
we substitute
= [ 0.90×0.20 ] / [ 0.90×0.20 + 0.80×0.60 + 0.95×0.20
= 0.18 / [ 0.18 + 0.48 + 0.19 ]
= 0.18 / 0.85
= 0.2118
Therefore, the probability that this employee belongs to group I is 0.2118
Answer:
Step-by-step explanation:
given:
x=3 and y=-4
to find:
4x-y
substitute the value of x and y
=4*3-(-4)
=12+4
=16
-x+y
substitute the vaue of x and y
=-3+(-4)
=-3-4
=-7
7-y-x
substitute the value of x and y
=7-(-4)-3
=7+4-3
=11-3
=8
Hope this helps u !!
Answer:
The solution would be (0, 5)
Step-by-step explanation:
In order to solve this system by substitution, simply take the value of y in the first equation and use it in place of y in the second. This will allow you to solve for x.
4x + 4y = 20
4x + 4(x + 5) = 20
4x + 4x + 20 = 20
8x + 20 = 20
8x = 0
x = 0
Now that we have the value of x, we can find the value of y.
y = x + 5
y = 0 + 5
y = 5
Answer:
A. 2(x+y+1)
Step-by-step explanation:
The expression is
x+2y+x+2
Collect like terms
x+x+2y+2
Add like terms
2x+2y+2
Factorise the expression
2(x+y+1)
