Answer: 5%

Step-by-step explanation:

Firstly, Convert metre to centimetre

100cm = 1m

Therefore,

4.5m = 450cm

If 450cm is X% of 90cm

That becomes :

450= X% × 90

450= 90X%

X% = 450/90

X% = 5%

There are four activities on the critical path, and they have standard deviations of 1, 2, 4, and 2. what is the probability tha
Anit [1.1K]

Standard deviations of the four activities of the critical path are 1,2,4,2.

Standard deviation of this critical path = Sum of square root of variance of this corresponding critical path

Standard deviation of critical path =\sqrt{1^2+2^2+4^2+2^2}

=\sqrt{1+4+16+4}

=\sqrt{25}

=5

Now we need to find the probability that the project will completed in 38 weeks given that its expected completion time is 40 weeks.

That is, we need to find P(X<38) :

z=\frac{38-40}{5}= \frac{-2}{5}=-0.4

P(X

Probability =0.5-0.16=0.34

Thus the probability that the project will be completed in 38 weeks is 0.34.

klasskru [66]

Answer: Rs. 1,52,550

Step-by-step explanation:

CP of motorcycle = 125000

Selling Price fixed = 125000 + 20% = 150000

10% discount = 150000*10% = 15000

SP after 10% discount

= 150000-15000= 135000

VAT at 13% = 135000 * .13 = 17550

Mr Gurung paid total

135000 + 17550 = 152550
