x in (-oo:+oo)
2/7 = x/14 // - x/14
2/7-(x/14) = 0
2/7-1/14*x = 0 // - 2/7
-1/14*x = -2/7 // : -1/14
x = -2/7/(-1/14)
x = 4
x = 4
i hope this helps
Answer:
58
Step-by-step explanation:
Solution:
p = 0.25
q = 1 - p = 0.75
x = 127
n = 480
psample = x/n = 127/480 = 0.2645
test statistic, z = (psample - p) / sqrt(pq/n) = (0.2645 - 0.25) / sqrt(0.25×0.75/480) = 0.733
Answer:
D
Step-by-step explanation:
Remember that parallel lines have equal slopes.
So, if the green line is parallel to the red line, and the slope of the green line is -2, this means that the slope of the red line <em>must</em> also be -2!
So, our answer is D.
And we're done!
