Answer: 0
Step-by-step explanation:
Given that :
Mean score on test = 5
Standard deviation on test = 2
Distribution = normal
The mean value when Converted to a z - distribution :
Zscore = (x - mean) / standard deviation.
Hence z score for the mean score will be :
X = mean score
Zscore = ( 5 - 5) / 2
Zscore = 0 / 2
Zscore = 0
Mean value when Converted to a z distribution will be 0
SAS. Sides because PN and MN are congruent as well as RN and QN. Since angle PNQ and angle MNR are vertical angles they are also congruent.
Answer:
4,151,347,200
Step-by-step explanation:
To find how many ways the train can be made up we use the permutation formula and the values given.
n = 16
k = 9
So there will be 4,151,347,200 different ways that the train can be made.
