<span>A zero pair is created when a pair of numbers, one positive and the other negative, equals a sum of zero.The main purpose of a zero pair is to simplify the process of addition and subtraction in complex mathematical equations featuring multiple numbers and variables. For example, in the problem 2+6-3-2, the positive 2 and the negative 2 cancel each other out because they are a zero pair, thus reducing the problem to 6-3. Examples of Zero Pair: -9 + 9 = 0</span>

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.

What is the value of x in the figure? Enter your answer in the box.<br> 145°<br> (2x + 15)°<br> x=

Nikolay [14]

Answer:

Answer: x=65

Step-by-step explanation:

Since they're vertical angles both sides are equal to 145 degrees

So, 145-15= 130 to get rid of the constant

Then, 130/2=65

To check you work add up all of your solutions to get 145

2*65=130 & 130+15=145

Therefore, x=65
