Probability of getting a pen in the first box:
7/12 = 0.58
0.58 x 100% = 58%
probability of getting a crayon in the second box:
5/10 = 1/2
half of 100 is 50, so 50%
or:
1/2 x 100% = 50%
Answer:
The expected earnings of the attendant for this particular period are: $12.66
Step-by-step explanation:
We have to calculate expected mean here:
So,
E(x) = ∑x*f(x)
Therefore, the expected earnings of the attendant for this particular period are: $12.66 ..
Answer:
y=-x+8
Step-by-step explanation:
y = mx + b is the basic formula
use the formula y2-y1/x2-x1 to get the slope to get m
-2-5/4-(-3)
-7/7
-1
then use the point slope formula y-y₁=m(x-x₁)
y-5=-1(x-(-3)
y-5=-1x+3
y=-x+8
3p + 7c = p....subtract 3p from both sides
7c = p - 3p
7c = - 2p ....now divide both sides by 7
c = -2/7p <==
