I drew these, as I just did these in math not too long ago. When I shaded it, it was in all four quadrants.
A linear equation can be represented by:
y = mx + b
Where m = slope, and b = y intercept.
The slope is a rate of change, so our slope is $150.
The y intercept is the point where the equation crosses the y axis, or the "initial amount" in this case $500.
So our equation will be:
y = 150x + 500.
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
Hey I'm looking for this answer, I saw you posted it 5 days ago, did you get the answer? thanks
