3/7 * 4 = 12/35 (Is this what your asking for?)
Answer:
C.) f(x) = −4x + 200
Step-by-step explanation:
Since the number is decreasing, you know the slope will be negative, eliminating the first two choices. The equation in the last choice does not match the given data, so it can be eliminated.
In other words, the easiest way to solve this problem is to check the answers against the given data.
_____
If you want to write the equation from scratch, you need to find the slope. That is ...
(change in number of cars)/(change in weeks) = (184 -192)/(4 -2) = -8/2 = -4
This matches only one answer, but you can go on to finish the equation by starting with point-slope form:
y -192 = -4(x -2)
y = -4x +8 +192 . . . . add 192, eliminate parentheses
y = -4x + 200 . . . . matches choice C.)

The correct answer is 'C'
First 3/4: this is actually 0.75. but the percent means we have to divide it by 100:
0.0075
3/25 is actually 0.12 (because it's equal to 12/100: i multiplied both numbers by 4)
and if it's a percent, again we "move to "move the point" or in other words divide by a 100:
0.0012 (think of dividing by 10 as of moving the coma to the left and adding zeros if there is noone to move)
the last one is equal to 55/100 (multiplied both by 5), so 11/20 % is 0.0055
I hope this was clear, let me know if you have questions!

Step-by-step explanation:
all i know is that it is not the IQR maybe its the MAD but im not sure
