Explanation:
The formula i.e.
Fuel Efficiency = 32-0.1*speed
represents that the efficiency on very lower speeds will be affected very minor as the multiple of 0.1 which will be subtracted from 32 will be small value.
Secondly, as per attached full question and graph plot, it is clear that up to 26.5 predicted (mpg), the trend of Residual (mpg) is increasing while after 26.5, it starts to decrease nearly linearly.
It's slop can be find out by two point formula i.e.
slope = m =(y2-y1)/(x2-x1)
=(1-2.5)/(27.5-27)
=(-1.5)/(0.5)
=-3
negative sign shows decreasing trend of second half plot
The answer would be 24x10 to the fourth
Answer:
B
Step-by-step explanation:
500 x 6 = 3000
154 x 6 = 924
Hope that helps!
Answer:
x=4
Step-by-step explanation:
To solve for x, we need to isolate it.
Start by adding 16 to each side to cancel out the -16:
-x=-4
-x is essentially -1 * x which can be written as -1x
-1x=-4
Divide both sides by -1 to isolate x
x=4
We can also plug this back into the equation to check:
-16-x=-20
-16-4=-20
-20=-20 --> correct!
