Answer:
im going to be honest i havent done this since las year and so i dont remember the value of that line outside but i think its 70*
Step-by-step explanation:
reason is because the c is originally 180* but it has more of and angle so the angles obv increases and you can get the angle by multiplying 70*times 7x and divide by 3
i say 3 because of the amount of angles in a triangle and the line outside if i remember correctly is the "angles" of a triangle and that would be your answer
The margin of error of the random selection is 0.29
The given parameters are:
--- the sample size
--- the standard deviation
--- the mean
--- the confidence level.
The margin of error (E) is calculated as follows:
So, we have:
The z-value for 90% confidence level is 1.645.
Substitute 1.645 for z
Take square roots
Multiply
Approximate
Hence, the margin of error is 0.29
