4 is B.

5 is true.

6- Statement 3: NO and ON are the same line. They are congruent by the reflexive property (a line segment is a reflection of itself)

If the mean score on a stress test is 5, the standard deviation is 2, and the distribution is normal, what would be the mean val

expeople1 [14]

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

A 100-meter-long christmas train needs 30 seconds to cross a 400-meter-long bridge. assuming the train goes at a steady speed, h

san4es73 [151]

Length of train : 100
length of bridge : 400
distance covered by the train to cross the bridge : (100 + 400) = 500
time taken by the train to cross : 30

speed = distance / time
speed = 500/30
speed = 16.67 meters per second <===
