M+5n=p for m <br> Solving for a variable
Verdich [7]

Answer:

M=p-5n

Step-by-step explanation:

Here we are given that M+5n=p

We are asked to solve this equation for M. In order to do that we will follow these steps.

Subtracting 5n from both sides we get

M+5n-5n=p-5n

M=p-5n

Hence , now we have our M as dependent variable,  whose value depends on the values of p and n. One or both  of them can be independent variable/.

Suppose task B follows task A. The likelihood that a problem will occur with task A is 0.5, and the time to correct the problem
jasenka [17]

Answer:

The risk consequence of both activities is 1.6 months.

Step-by-step explanation:

We can define a randome variable D: total delay time for the project, and calculate its expected value.

This would be the risk consequence of both activities.

The expected delay time for the project is the sum of the expected delay for task A plus the expected delay for task B. It is assumed the likelihood of a problem in any task is independent of the other.

Then, each expected delay for a task is equal to the probability of a problem multiplied by the consequence (delay time).

E(D)=E(D_a)+E(D_b)=p_aT_a+p_bT_b\\\\E(D)=0.5*2+0.2*3=1+0.6=1.6

The risk consequence of both activities is 1.6 months.

Let f(x) = x^2 + -8x + 19 what is the minimum value of the function? Enter your answer in the box
crimeas [40]
<h2>(4,3)</h2>

Function Template

ax^2 + bx + c

x^2 + -8x + 19

Max/Min Point Template

- (b / 2a)

- (-8 / 2 * 1)

- (-8 / 2)

- (-4)

4

Substitute the value into the function.

(x) = x^2 + -8x + 19

f(4) = 4^2 + -8(4) + 19

f(4) = 16 + (-32) + 19

f(4) = 3

Minimum point = (4,3)
