Steps To Solve:
17 - 2v = -53
~Subtract 17 to both sides
17 - 2v - 17 = -53 - 17
~Simplify
-2v = -70
~Divide 2 to both sides
-2v/-2 = -70/-2
~Simplify
v = 35

Answer:
Standard deviation gets smaller
Step-by-step explanation:
No. of students = 45
The class had an average of 56 words per minute (WPM) with a standard deviation of 7 WPM.
The teacher realized that the data from one student who typed 55 WPM was not entered.
So, new sum = 2520+55
New sum =2575
So, new mean =
New mean =57.22
Standard deviation is the measure of distance between observation and mean
So, if number gets closer to mean , Standard deviation gets smaller . if the numbers get bigger , Standard deviation gets bigger.
Since 55 is closer to 57.22
So, Standard deviation gets smaller
