Answer:
[4 + 1] *[7-2] =25
Step-by-step explanation:
[4 + 1] *[7-2] =25
We need to get to 25
What makes 25
5*5
4+1 =5
7-2 =5
5*5 =25
So we need brackets around 4+1 and around 7-2
Answer:
B
Step-by-step explanation:
The circle has to be hallow in order for it to be greater than or less than. The arrow is going below 4 because the circle is on 4 and the arrow is pointing to the left side.
The answer to this question is D
Answer: d 9/4
Step-by-step explanation: Multiplicative inverse is simply flipping the number (reciprocal). When multiplied the value is always 1. 4/9 * 9/4 =36/36 =1
Answer:
the standard deviation of the critical path is 8
Step-by-step explanation:
The computation of the standard deviation of the critical path is shown below:
As we know that
Variance = Standard deviation^2
Now the variance of the critical path is
= Variance 1 + variance 2 + variance 3 + variance 4
= 4^2 + 4^2 + 4^2 + 4^2
= 64
Now the standard deviation would be
= √64
= 8
hence, the standard deviation of the critical path is 8
