Evaluate the given expression. Subscript 5 Baseline P Subscript 2 a. 40 c. 25 b. 32 d. 20

Leto [7]

Answer:

d. 20

Step-by-step explanation:

The given question implies 5 permutation 2, i.e $_{5}$ $P_{2}$ .

But,

$_{n}$ $P_{r}$ = $\frac{n!}{(n - r)!}$

So that for $_{5}$ $P_{2}$ , n = 5 and r = 2.

$_{5}$ $P_{2}$ = $\frac{5!}{(5 - 2)!}$

= $\frac{5!}{3!}$

= $\frac{5*4*3*2!}{3*2!}$

Cancel out 3 and 2 with respect to the numerator and denominator.

$_{5}$ $P_{2}$ = 5 * 4

= 20

Therefore,

$_{5}$ $P_{2}$ = 20

So that the correct option is D.

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.

H(x) = x^2+6 g(x) = 8x-5 show that hg(x)=19 simplifies to 16x^2 - 20x + 3 = 0

Studentka2010 [4]

Answer:

h(x)=x²+6 and g(x)=8x-5

prove that hg(x)=19

Step-by-step explanation:

step 1: hog(x)=h[g(x)]

step 2: h(8x-5)

step 3: h(8x-5)= (8x-5)²+6

step 4: (8x-5)(8x-5)+6

step 5: 16x² +15x +6
