Step-by-step explanation:
if u see the parallel line then it should be the same and similar
Answer:
With n = 50, both conditions(np > 5, n(1-p) > 5) are satisfied, so a random sample of 50 cars would have been large enough.
Step-by-step explanation:
Binomial probability distribution
Probability of exactly x sucesses on n repeated trials, with p probability.
Can be approximated to the normal distribution if:
np > 5, n(1-p) > 5
70% of the drivers traveling on a major interstate highway exceed the speed limit.
So p = 0.7.
Would a random sample of 50 cars have been large enough and why?
With n = 50
np = 50*0.7 = 35 > 5
n(1-p) = 50*0.3 = 15 > 5
With n = 50, both conditions(np > 5, n(1-p) > 5) are satisfied, so a random sample of 50 cars would have been large enough.

Step-by-step explanation:
in a 45-45-90° triangle, the length of legs to hypotenuse is 1 :
Answer:
x=-8
Step-by-step explanation:
y=8 is a horizontal line crossing the y-axis at 8
A line perpendicular to this would be a vertical line crossing the x-axis at -8
