Hello!
First you have to get the equation into slope-intercept form
Slope-intercept form is y = mx + b
-2x + 4y = -8
Add 2x to both sides
4y = 2x - 8
Divide both sides by 4
y = 1/2 x - 2
The graph is a line that goes through the points (0, -2), (-2, -3), (2, -1) and
(4, 0)
Hope this helps!
0.27 x 93 = 25.11
25.11 is the answer
Answer:
-2.25
Step-by-step explanation:
We have that the mean (m) is equal to 500, the standard deviation (sd) 20
They ask us for P (x <455)
For this, the first thing is to calculate z, which is given by the following equation:
z = (x - m) / sd
We have all these values, replacing we have:
z = (455 - 500) / (20)
z = -2.25
Answer:
110 is the correct answer...
The answer is 12 hours. It would take 12 hours.
