Answer:
Option B
Step-by-step explanation:
As per the question:
The variance of the 48 Econ 202, = 16 inches
The variance of 63 Econ 203 = 14 inches
Now, to test the variance of two populations:
For 48 Econ 202:
For 63 Econ 203:
On comparing the two, the test statistics is given by;
F = 
F = 
2x^2y√6x
the image has the answer in a mor clear form
Answer:
Step-by-step explanation:
slope intercept form is y = mx + b
17 = y + 4x....we have to get y on one side and everything else on the other side.....so the easiest way would be to subtract 4x from both sides
17 - 4x = y + 4x - 4x....combine like terms
17 - 4x = y...rearrange
y = -4x + 17 <===== slope intercept form
Answer:
reflected across the x-axis is 3,-2 and the y axis is -3,2
Step-by-step explanation:
When you reflect over the X axis it will stay the same numbers but change the Y axis sign. the same thing happens to the y -axis but the x changes siogns instead
