Answer:
We need to evaluate this: [(-16)+4] / [(-2)+5]
First, we do the brackets:
[(-16)+4] = -16 + 4 = -12
[(-2) + 5] = -2 + 5 = 3
Now, we only need to divide, as we have calculated both brackets:
-12/3 = -4
(Remember that when dividing a negative number by a positive one, we always obtain a negative)
So the result is -4
Step-by-step explanation:
D (-2,2)
:) good day
good day
Its 4 by the way cause it is
The difference in gallons per day used is 3.6.
The formula to calculate a z-score is:

,
where X is the value used to calculate the score, μ is the mean and σ is the standard deviation. We have the z-scores so we must work backward:

For both equations, we will cancel the 1.2 by multiplying both sides:

Now we will cancel 2.2 from both equations by adding it to both sides:
3.6+2.2=X-2.2+2.2 and 0+2.2=X-2.2+2.2
5.8=X and 2.2=X
The difference in gas used per day would be given by
5.8-2.2 = 3.6.
Answer:
3/2
Step-by-step explanation:
The equation 3x-2y=4 can be written in the form of y=mx+c where m is the slope and c is the y intercept.
Therefore
2y=3x-4 and dividing both sides by 2 to have y at the LHS
y=3/2x-2
Therefore, 3/2 represents the gradient/slope
