Answer:
4
Step-by-step explanation:
f(p) = 3p-2
Let p=2
f(2) = 3*2-2
= 6-2
= 4
The mean does not always equal the median.
The mean does not never equal the median.
But the mean does sometimes equal the median.
Answer:
$19,100
Step-by-step explanation:
The expected profit would be the probability of profit multiplied by the profit and the sum of probability of loss multiiplied by the loss.
So, we can say:
E(p) = P(p)*P + P(L)*L
Where
E(p) is expected profit
P(p) is probabilty of profit (0.7)
P is the profit (35,000)
P(L) is probability of loss (0.3)
L is the loss (-18,000)
Substituting these values, we get:
E(p) = P(p)*P + P(L)*L
E(p) = (0.7)(35,000) + (0.3)(-18,000)
E(p) = 19,100
The expected profit is $19,100
T=(h*5)+6.5 should be it because it is the number of hours multiplied by 5 days and then you add the 6.5 hours
Answer:
x = -2 and y = 0
Step-by-step explanation:
5x + y = -10
4x - 7y = -8
Rearrange the first equation to equal y.
5x + y = -10
y = -10 - 5x
Replace y in the second equation with the first equation.
4x - 7y = -8
4x - 7(-10 - 5x) = -8
4x - (-70 -35x) = -8
4x + 70 + 35x = -8
Rearrange the equation to find x.
4x + 35x = -8 - 70
39x = -78
x = -2
Now that you know x, use the rearranged first equation to find y.
y = -10 - 5x
y = -10 - 5(-2)
y = -10 + 10
y = 0
