This is the concept of probability and statistics, the z-score associated by the probability of 25% will be obtained using the z-tables, and hence we shall have:
P(x)=25=0.25
thus checking the z-score that gives us the probability of 0.25 we get:
-0.67
the answer is z=-0.67
Answer:
85%
Step-by-step explanation:
The whole is 100 squares or 100%. Eighty-five squares are shaded in. 85/100 or 85% is the percentage! Hope this Helps!

Answer:
slope = 1
Step-by-step explanation:
In the attachment, we have shown rise and run as 3 units each. The segments could be drawn 1 unit long. In any event, the ratio is the slope:
slope = rise/run = 3/3
slope = 1
_____
It is most convenient to draw the rise and run segments from/to places where the line crosses grid intersections. Often, but not always, the y-intercept will be such a point. Then you can look for the nearest grid crossing for figuring rise and run.
Here, the y-intercept is (0, 1), and the closest grid crossing to the right is (1, 2). The rise is 2-1 = 1, and the run is 1-0 = 1. The ratio is 1/1 = 1, same as above. The ratio of rise to run will be the same everywhere for a straight line.
Answer:
80°
Step-by-step explanation:
4x + 5x = 180, so 9x = 180, x = 180/9 = 20
So m∠SVW = 4x + 4*20 = 80°
Answer:
16
Step-by-step explanation:
2x+3 = 11
2x= 8
x = 4
4(x) = 4(4) = 16
