We have been given that the total number of households she surveyed = 150
Now, out of 150, 35 of them said they turn out the lights each year on Halloween.
Now, in order to find the percentage of households that turn out the lights each year on Halloween, we will divide 35 by 150 and then multiply the result with 10.
Thus, we the required percentage is given by
Therefore, to nearest percent is 23%.
Hence, the estimated population proportion of households that turn out the lights each year on Halloween is 23%
Answer:
b ≈ 7.8
Step-by-step explanation:
using the law of sines
∠ A = 180° - 105° - 40° = 180° - 145° = 35° , then
=
( cross- multiply )
b × sin35° = 7 × sin40° ( divide both sides by sin35° )
b = ≈ 7.8 ( to the nearest tenth )
