Answer:
B. the mean of city A is greater than the mean of city B
Step-by-step explanation:
Find mean by adding every number than dividing by the total of numbers added so...
97+98+96+98+99=488 and 488/5=97.6 which is higher than the mean of city B
Answer:
Step-by-step explanation:
Slope-intercept from: y = mx +c
Here, m is the slope & c is the y-intercept.
So, we have to isolate y. To isolate y first subtract 2x from both sides.
2x - 3y = -9
-3y = -2x -9
Now, divide the entire equation by the co efficient of y (-3)
If it's parallel to the y axis this means the slope will be any number over 0 with means it's D undefined
