Answer:
19/30
Step-by-step explanation:
had this in an old problem in school
:D
Answer:
Step-by-step explanation:
Given that x = no of movies high school students watched is N(6.8, 1.8)
Sample size = 36 and hence std error = 1.8/6 = 0.3
(two tailed test)
Mean difference = 6.2-6.8 = -0.6
Test statistic z = -0.6/0.3= -2
p value = 0.02275
Since p <0.05 we reject H0.
There is evidence to show that college students watch fewer movies a month than high school students
Solve:
Recall that cot(x) really is just 1/tan(x).
Thus, we can say:
Isolate the variable to solve directly for theta.
However, that's not the only solution:
For instance,
is another solution.
In fact, there are an infinite amount of solutions we can have that will satisfy this equation because of the fact that the tangent wave is periodic every π.
Thus, we can say for every π periods, we will have a solution.
Or:
, where
By substituting Θ, we can say that the solutions are:
, where
Answer:
I think it's B like the other person, said.
Step-by-step explanation:
Step-by-step explanation:
Explanation: To find the width, multiply the length that you have been given by 2, and subtract the result from the perimeter. You now have the total length for the remaining 2 sides.
