Given:
Two points are N(-1,-11) and P(-1,-3).
To find:
The value of NP.
Solution:
Distance formula:
Two points are N(-1,-11) and P(-1,-3). Using distance formula, we get
On further simplification, we get
Therefore, the value of NP is 8 units.
Answer:15.7
Step-by-step explanation:
Answer:
374.4
Step-by-step explanation:
All items related to the maintenance are 20% more expensive, it means that each datum is 20% bigger including the average.
The variance its a dispersion measurof the data and its calculated of this way:
Here n is the number of data, is the average and represent each datum. The increment in 20% in each parameter can be represented multiplying for 1.2, of this way
Factorizing the 1.2 we have:
That is:
The new variance is
5:6 Hope this helps you!!
