Step-by-step explanation:
10.35 according to chemistry . product
90 seats are on the right and 60 seats are on the left.
Answer = 72°
Complementary angles always add up to be 90.
We can write the smaller angle as x and the bigger angle as 4x, because it is 4 times bigger than x.
x + 4x = 90
5x = 90
x = 18.
This proves the smaller angle, or angle B, is 18. We know angle A is 4 times as big as 18, so we can multiply 18 x 4 to get 72.
Double check = 72 + 18 = 90
Answer:
300 divided by 50=6 meters per second

Answer:
The minimum sample size is 
Step-by-step explanation:
From the question we are told that
The confidence interval is 
The margin of error is 
Generally the sample proportion can be mathematically evaluated as



Given that the confidence level is 98% then the level of significance can be mathematically evaluated as



Next we obtain the critical value of
from the normal distribution table
The value is

Generally the minimum sample size is evaluated as
![n =[ \frac { Z_{\frac{\alpha }{2} }}{E} ]^2 * \r p (1- \r p )](https://tex.z-dn.net/?f=n%20%20%3D%5B%20%5Cfrac%20%7B%20Z_%7B%5Cfrac%7B%5Calpha%20%7D%7B2%7D%20%7D%7D%7BE%7D%20%5D%5E2%20%2A%20%20%5Cr%20p%20%281-%20%5Cr%20p%20%29)
