The expected activity time in PERT analysis is calculated as: the weighted average of a, m, and b, with m weighted 4 times as he

maria [59]

Answer:

$\text{the weighted average of a, m, and b, with m weighted 4 times as heavily as a and b.}$

Step-by-step explanation:

$\text{The expected activity time in PERT analysis is calculated as:}$

$\mathbf{\dfrac{a+4m + b}{6}}$

$where;$

$\text{a = optimistic duration; }$

$\text{m = most likely duration and;}$

$\text{ b = pessimistic duration from the above formula.}$

Find the values of x and y. The diagram is not to scale.

Aleksandr [31]

Step 1

<u>Find the value of x</u>

we know that

$(x-1)\°=74\°$ -------> by corresponding angles, because the given lines are parallel

Solve for x

$(x-1)\°=74\°\\x=74+1 \\ x=75\°$

Step 2

<u>Find the value of y</u>

we know that

$(x-1)+40+(y-2)=180$

substitute the value of x and solve for y

$(75-1)+40+(y-2)=180$

$74+40-2+y=180$

$112+y=180$

$y=180-112$

$y=68\°$

therefore

<u>the answer is the option B</u>

$x=75\°, y=68\°$

Y=-2/3x+3 please show the work thank you ;)

Ivahew [28]

Answer:

Step-by-step explanation:

Looking at y=-%282%2F3%29x%2B3 we can see that the equation is in slope-intercept form y=mx%2Bb where the slope is m=-2%2F3 and the y-intercept is b=3

Since b=3 this tells us that the y-intercept is .Remember the y-intercept is the point where the graph intersects with the y-axis

So we have one point

Now since the slope is comprised of the "rise" over the "run" this means

slope=rise%2Frun

Also, because the slope is -2%2F3, this means:

rise%2Frun=-2%2F3

which shows us that the rise is -2 and the run is 3. This means that to go from point to point, we can go down 2 and over 3

So starting at , go down 2 units

and to the right 3 units to get to the next point

Now draw a line through these points to graph y=-%282%2F3%29x%2B3

So this is the graph of y=-%282%2F3%29x%2B3 through the points and
