Answer:
The answer to your question is: letter d
Step-by-step explanation:
Convert 75° to radians
360° ----------------- 2π rad Rule of three
75° ----------------- x
x = (75 x 2π rad ) / 360
x = 150π rad / 360
x = 15π rad / 36 Simplify
x = 5 π rad / 12
We are going to use a continuity correction factor. When you use a normal distribution to get the estimated binomial distribution, you're going to have to use a continuity correction factor. So with this, the data will become from <span>20 - 35 it will now become 19.5 to 35.5.
So we are going to use the z table for this problem. So if we are looking for the z value, the formula would be: </span>x – μ / σ<span>
get the value of the first z value:
</span>z1 = (19.5 - 30) / 9 = -1.167
get the value of the second z value:
<span>z2 = (35.5 - 30) / 9 = 0.61
</span>
So getting the probability of both:
P(-1.167 < z < 0.61) = P(Z ≤ b) – P(Z ≤ a) = <span>0.6075</span>

Minus the "yx" on the top from the ones on the bottom so the top has none and the bottom has 4
Ok, so...what is the question?...
