The question is incomplete other wise it is really easy to solve if you now how to make the line of equation. As we know the formula to calculate the line of equation is y - y1 = m (x - x1)

Where m is the slope. y1 is the first y co ordinate. x1 is the first x co ordinate.

And the formula for slope is as we know is m = y2 - y1 divided by x2 - x1.

Where m is the slope. y2 is the second y co ordinate. y1 is the first y co ordinate. x2 is the second x co ordinate. x1 is the first x co ordinate.

Find the maximum value of c=4x+2y 2x+2y less than or equal to 10 3x+y less than or equal to 9

svp [43]

Answer: 14

Step-by-step explanation:

Step 1: Graph both equations to find the vertices (see attached):

The graph shows vertices at: (0, 0), (3, 0), (0, 5) and (2, 3)

Step 2: Input the coordinates of the vertices into the given function (c = 4x + 2y):

(0, 0): 4(0) + 2(0) = 0
(3, 0): 4(3) + 2(0) = 12
(0, 5): 4(0) + 2(5) = 10
(2, 3): 4(2) + 2(3) = 14

Step 3: Evaluate the value from Step 2 to find the maximum (largest).

the largest value between {0, 12, 10, 14} is 14

You have just used the network planning model and found the critical path length is 30 days and the variance of the critical pat

ollegr [7]

Answer: The probability that the project will be completed in 33 days or less is equal to 0.73 .

Step-by-step explanation:

We assume that this is a normally distribution.

Given : The critical path length is 30 days .

i.e. Population mean = $\mu=30$

Variance : $\sigma^2=25$

Then, standard deviation : $\sigma=\sqrt{25}=5$

Z-score : $z=\dfrac{x-\mu}{\sigma}$

The value of z corresponding to 33 = $z=\dfrac{33-30}{5}=0.6$

Now, the p-value = $P(x\leq33)=P(z\leq0.6)=0.7257469\approx0.73$

Hence, the probability that the project will be completed in 33 days or less is equal to 0.73.
