The larger of two numbers is 12 more than the smaller number. If the sum of the two numbers is 74, find the two numbers. Show ho

olya-2409 [2.1K]

Set up two equations.
s + 12 = l , s + l = 74 (these equations represent the problem)

s + (s + 12) = 74 plug in "l" to the second equation.

2s + 12 = 74 combine like terms.

2s + 12 - 12 = 74 - 12 subtract to isolate the variable

2/2s = 62/2 divide to isolate the variable.

s = 31. This means the smaller number is 31.

31 + 12 = 43. since the larger number is 12 more than the smaller, add 12.

l = 43 the larger number has a value of 43.

small number = 31
larger number = 43

hope this helps! :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<u> </u><u>0.73</u> .

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.
